However, playgrounds must be designed with safety in mind. One of the most important elements in reducing the risk of injury is the surface beneath equipment. Properly specified playground or play area matting can significantly reduce the severity of injuries caused by falls.

For specifiers, contractors, schools, councils, and facilities managers, understanding the legal framework surrounding playground surfacing is essential. Failing to comply with relevant legislation and safety standards can increase the risk of injury and expose organisations to legal liability.

This article explains the key legislation and safety standards affecting playground and play area matting in the UK, how a risk-based framework helps organisations remain compliant, and what to consider when selecting and maintaining appropriate surfacing.

Why Playground Matting Matters

Playgrounds are designed to encourage movement, exploration, and social interaction, but they are also environments where falls are inevitable.

Because climbing frames, swings, and other equipment introduce height and motion, the surface beneath them plays a critical role in reducing injury risk. Without appropriate surfacing, even relatively low falls onto hard ground such as concrete or compacted soil can result in serious harm.

This is why shock-absorbing playground matting is so important. It helps reduce the impact energy of a fall and is a key factor in safer play area design, particularly in commercial and public-use environments.

A key measure used to assess this performance is Critical Fall Height (CFH), which indicates how effectively a surface can absorb impact from different heights.

Understanding the Legal Framework and Safety Standards

The use of playground surfacing is not governed by strict prescriptive legislation on materials or construction methods. Instead, organisations are required to ensure that playground environments are safe through risk assessment and appropriate control measures.

This duty is set out in key UK legislation, including:

• Health and Safety at Work etc. Act 1974 – requires safe systems of work for both employees and the public
• Occupiers’ Liability Acts 1957 and 1984 – establish a duty of care to ensure visitors are reasonably safe
• Management of Health and Safety at Work Regulations 1999 – requires suitable and sufficient risk assessments

To support these legal duties, organisations rely on recognised industry standards that define how safety performance should be assessed.

The most important of these is BS EN 1177, which sets out how playground surfacing is tested for impact attenuation. This standard measures how well a surface reduces injury risk from falls, using the Head Injury Criterion (HIC) as the benchmark for safety performance.

Alongside this, BS EN 1176 provides guidance on playground equipment design, including the requirement that appropriate surfacing is installed within defined fall zones.

Together, legislation and standards ensure that playground surfacing is not chosen arbitrarily, but selected and installed based on measurable safety performance.

Critical Fall Height and Fall Zones

To correctly specify playground matting, two key concepts must be understood: Critical Fall Height and fall zones.

Critical Fall Height (CFH)

Critical Fall Height refers to the maximum height from which a child can fall onto a surface without sustaining a life-threatening head injury. It is determined through controlled testing, where impact performance is measured using the Head Injury Criterion (HIC).

The resulting CFH rating indicates the protective capability of a surface and is central to safe product selection.

Fall Zones

Fall zones are the areas surrounding playground equipment where a child is likely to land during use or in the event of a fall. This includes not only the immediate area beneath equipment, but also surrounding zones influenced by movement—such as the arc of swings or slide exit paths.

For a surface to perform effectively, the entire fall zone must be fully covered with appropriate surfacing. Gaps, uneven coverage, or exposed hard ground can significantly increase injury risk.

Correct fall zone design, combined with the right CFH-rated material, ensures the surface performs as intended under real-world conditions.

Independent Testing and Product Performance

To demonstrate compliance and performance, playground surfacing is tested using recognised standards such as BS EN 1177. This provides measurable data on impact attenuation and ensures products perform consistently in real-world conditions. 

Grass-Based Safety Mats

Products such as EASI Grass Mats and ORBIK Grass Mats are designed for installation over natural turf, providing reinforced protection while maintaining a grass surface.

Independent testing has demonstrated that our Polymax EASI and ORBIK grass mats can provide significant fall protection when installed correctly on suitable ground conditions.

These products are tested in accordance with BS EN 1177 safety standards, confirming their suitability as shock absorbing surfaces in playground environments.

Additional benefits include:

• Excellent drainage
• Reduced mud formation
• Natural grass appearance
• Durable water resistant mats
• Suitable for high traffic areas

Critical Fall Height Performance – Polymax Play Safety Tiles

Rubber crumb safety tiles are one of the most common forms of commercial playground surfacing, particularly where defined fall heights must be matched to specific safety surfaces.

Polymax Play Safety Tiles are manufactured from recycled rubber crumb and provide consistent shock absorption across the surface.

Independent laboratory testing of Polymax Play Safety Tiles, carried out in accordance with EN 1177:2018 for the determination of impact attenuation (HIC), produced the following results when the tiles were installed over a concrete base:

These results demonstrate how surfacing thickness directly affects fall protection performance.

When specifying rubber tiles, the chosen thickness must always match or exceed the free height of fall of the playground equipment.

For example:

• Equipment with a fall height of 1.5 metres should use Polymax Play Safety Tiles tiles that have a minimum thickness of 50mm or greater. 

Correct specification ensures the surface provides effective protection across the designated fall zone.

Why Certification Matters

Testing conducted by a UKAS-accredited laboratory confirms that playground surfacing has been evaluated using controlled laboratory procedures and calibrated equipment in accordance with relevant standards.

For specifiers and operators, this means:

• Verified Critical Fall Height performance
• Confidence in compliance with BS EN 1177
• Consistency in product quality and safety performance
• Supporting documentation for duty of care requirements

This evidence-based approach helps organisations demonstrate that reasonable steps have been taken to manage risk effectively.

Installation Compliance Considerations

Even high-quality playground matting will only perform correctly if installed appropriately.

Several factors influence installation compliance, including:

• Ground preparation
• Base stability
• Surface levelness
• Drainage conditions
• Correct fall zone coverage

For example, poor drainage can allow water to accumulate beneath the surface, potentially affecting performance during frost conditions.

Ensuring the installation follows manufacturer guidance helps maintain the intended safety performance of the surface.

Who Is Legally Responsible for Playground Safety?

Responsibility for playground safety usually lies with the organisation that owns or manages the site.

This may include:

• Local authorities
• Schools and academies
• Nurseries
• Leisure centres
• Property owners
• Commercial playground operators

Under occupiers' liability legislation, these organisations must take reasonable steps to ensure playground equipment and surfacing remain safe for users.

This includes selecting appropriate playground or play area matting and maintaining it throughout its lifespan.

The Impact of Weather on Playground Matting Performance

Outdoor playground surfaces must withstand continuous exposure to weather conditions.

Several environmental factors can influence performance.

UV Exposure

Long-term ultraviolet exposure may gradually degrade certain materials, potentially reducing elasticity.

Frost and Freeze-Thaw Cycles

Freeze-thaw cycles can cause ground movement if water becomes trapped beneath the matting.

Rain and Drainage

Surfaces designed to allow water to pass through help prevent pooling and maintain consistent safety performance.

High-quality playground matting systems such as the Polymax Play Tiles are designed to remain durable despite seasonal weather variations.

Playground Maintenance and Ongoing Inspection

Regular inspection is an essential part of playground maintenance.

Typical checks should include:

• Surface wear or damage
• Loose or lifted tiles
• Grass growth through reinforcement mats
• Drainage effectiveness
• Changes in ground levels

Routine inspections help identify issues early before they develop into safety hazards.

Is Ongoing Assessment a Legal Requirement?

UK legislation does not specify a fixed inspection schedule for playground surfacing. However, operators are required to ensure that playground environments remain safe.

Industry guidance from organisations such as RoSPA recommends three types of inspection:

• Routine visual inspections
• Operational inspections
• Annual independent inspections

These assessments demonstrate that operators are actively managing risk in accordance with health and safety obligations.

Common Compliance Mistakes

Several issues can lead to non-compliance in playground environments.

Common examples include:

• Installing surfacing with insufficient Critical Fall Height
• Incorrect fall zone coverage
• Poor drainage beneath surfaces
• Failure to conduct regular inspections
• Replacing damaged tiles with incompatible materials

Working with Polymax and using our products tested to recognised safety standards can help avoid these problems.

Legislation and safety standards referenced in this article are correct at the time of publication. Organisations should ensure they review the most current regulations and guidance when specifying playground safety surfacing.

Choosing the right O-ring involves more than just size and material. One of the most critical but often overlooked factors is the material hardness. This indicates how soft or firm a rubber compound is, influencing how well the O-ring seals, resists pressure, and performs in real-world conditions.

For most O-ring applications, Shore A hardness (abbreviated ShA or HA) is the primary scale used. However, understanding how different Shore scales work provides important context for making the best choice.

What Is Shore Hardness?

Shore hardness is a measure of how resistant a material is to indentation, indicating how soft or hard it is on a standardised scale. It is determined using a device called a durometer, which applies a standardised force to a material and measures its resistance to indentation. The result is a numerical value that helps compare the hardness of different materials.

Overview of Shore Hardness Scales

There are several Shore scales, but the most commonly used for polymers and elastomers are:

• Shore A (ShA or HA): Used for soft, flexible materials like rubber, silicone, and other elastomers. This is the standard scale for O-rings. The scale ranges from 0 (very soft) to 100 (very hard). For example, a 70 ShA O-ring offers a balance of flexibility and durability.
• Shore D (ShD or HD): Designed for harder plastics such as nylon, polycarbonate, and rigid thermoplastics. Shore D is not used for standard rubber O-rings, but may be referenced for rigid back-up rings (PTFE) or non-elastomeric sealing components.
• Shore 00: Less common in O-ring applications, Shore 00 is used for very soft gels or foams, like sponge rubber or soft silicone gels.

Which Shore A Hardness Rating is Best for your Application

The Shore A hardness rating of an O-ring has a direct impact on its ability to seal, resist deformation, and withstand pressure. As a guide what rating should you use for different applications.

• Soft O-rings (40–60 ShA): Highly flexible, excellent for low-pressure applications or when sealing against rough or uneven surfaces. However, they may wear more quickly and be prone to extrusion under high pressure.
• Medium O-rings (70 ShA): The most commonly used hardness for O-rings, striking a balance between elasticity and strength. Suitable for both dynamic and static sealing in hydraulics and pneumatics.
• Hard O-rings (80–90 ShA): Best for high-pressure environments. These O-rings are more resistant to extrusion and abrasion but require smooth sealing surfaces and higher installation force.

Reduce Cost and Downtime by Getting your Selection Right

Understanding the Shore Hardness scale, especially Shore A (ShA) for elastomers, is essential for selecting the right O-ring. By matching the material hardness to your application's requirements, you can ensure a more reliable, longer-lasting seal that minimises downtime and maintenance.  To find out more contact our team of experts.

Ensuring food-contact O-rings, seals, gaskets, and silicone tubing are safe and compliant is essential for manufacturers, installers, and end-users operating in the United States, European Union, and global food-processing markets.

Regulatory compliance helps:

• Protect consumer health
• Reduce contamination risk
• Ensure export-ready certification
• Support hygienic design standards in processing systems

This guide compares the three most important frameworks for food-contact elastomers and sealing components:

• FDA 21 CFR (U.S.) – focuses on ingredient safety, extractable limits, and migration testing.
• EC 1935/2004 (EU) – prioritises migration limits, traceability, and documentation.
• 3-A Sanitary Standards (3-A SSI) – ensures hygienic design, cleanability, and bacterial prevention in equipment.

Achieving FDA and EC 1935 compliance is essential for manufacturers exporting to the U.S. and EU, while 3-A compliance ensures hygienic design in food and pharmaceutical systems worldwide.

Key Differences Between FDA, EC 1935, and 3-A Sanitary Standards

Key Insight

• FDA focuses on chemical safety and permitted substances
• EU EC 1935/2004 focuses on migration limits and traceability across materials
• 3-A SSI focuses on equipment design, cleanability, and hygienic performance

Together, they define the global compliance landscape for food-contact sealing components.

Steps to Achieve FDA 21 CFR Compliance

FDA compliance for food-contact elastomers and plastics follows a structured process:

1. Verify Approved Materials (Positive List Compliance)

Materials must comply with FDA 21 CFR regulations, especially:

• 21 CFR 177 (polymers used in food-contact applications)
• Only listed additives, stabilisers, and resins may be used
• New substances require a Food Contact Notification (FCN)

2. Extraction & Migration Testing

FDA requires lab testing to measure migration of substances into food simulants. EC 1935/2004 also requires migration testing but uses different simulants and measurement units.

3. Good Manufacturing Practices (GMP)

• Clean, traceable production environments guarantee consistent quality and contamination prevention.
• Essential for manufacturers and reassuring for installers and end-users.

4. Declaration of Compliance (DoC)

• A self-issued document summarising compliance, usually backed by independent lab reports.
• Required for audits, inspections, and export documentation.

Authority cue: A properly prepared DoC demonstrates regulatory compliance to FDA, EC, and 3-A standards, reinforcing credibility with customers and regulators.

Selecting the Right O-Rings, Seals, and Tubing

When specifying components for food-contact applications, consider:

• Regulatory compliance: FDA & EC 1935 for chemical safety; 3-A SSI for hygienic design.
• Material properties: Durometer/hardness, chemical compatibility, temperature resistance.
• Documentation: Lab reports, DoC, audit-ready datasheets.
• Installation suitability: CIP/SIP systems, hygienic operation, maintenance access.

Compliance Comparison at a Glance

• • FDA: Focused on ingredient safety and extractable limits; critical for the U.S. market.
  • EC 1935/2004: Ensures migration limits, traceability, and safe food-contact materials for EU export.
  • 3-A SSI: Ensures hygienic design, cleanability, and bacterial prevention, supporting CIP/SIP systems.
  • Manufacturers exporting to U.S. and EU markets need both FDA and EC 1935 compliance.
  • Proper documentation and independent testing support audits, inspections, and global market access.

Tip: Following these standards ensures high-quality, safe O-rings, gaskets, and tubing for food-contact applications worldwide.

Selecting the correct gasket material is critical to preventing leaks, reducing downtime, and ensuring long-term system reliability. Whether in chemical processing, food production, or high-pressure systems, material choice directly impacts performance, safety, and cost.

Choosing the right material starts with understanding the operational parameters under which the gasket will function. Choosing the right material ensures reliability, longevity, and safety.

Step 1: Define Operating Conditions (External Environment)

The first step in material selection is to clearly define the conditions in which the gasket or seal will operate. These external factors determine the baseline requirements for performance and durability.

Key considerations include:

• Temperature: Materials must withstand both the minimum and maximum operating temperatures. For example, graphite gaskets perform well in high-temperature environments, whereas elastomers are typically better suited to moderate ranges.
• Pressure: Higher pressures require materials with sufficient compressive strength and structural integrity, such as metal gaskets or reinforced composites.
• Chemical Exposure: The material must resist any fluids or gases it will contact. In chemically aggressive environments, fluoroelastomers such as Viton® are often preferred due to their superior resistance to fuels, oils, and solvents.

Understanding these operating conditions helps narrow down suitable material groups before evaluating specific properties.

Step 2: Evaluate Material Behaviour (Performance Properties)

Once operating conditions are defined, the next step is to assess how candidate materials perform under those conditions. This focuses on the inherent properties that determine sealing effectiveness over time.

• Key factors include:
  • Thermal Stability: The material must maintain its integrity, flexibility, and sealing capability across the full temperature range without hardening, cracking, or degrading.
  • Chemical Compatibility: Ensure the material will not swell, corrode, or chemically break down when exposed to process media.
  • Pressure Retention: The material must be capable of maintaining a reliable seal under system pressure without extrusion or permanent deformation.
  • Environmental Resistance: Consider exposure to moisture, UV radiation, abrasion, or outdoor conditions that may affect long-term performance.
  • Durability and Lifespan: Evaluate how the material performs under continuous operation, including resistance to wear, compression set, and ageing.

  This step ensures the selected material not only meets initial requirements but continues to perform reliably over time.

Step 3: Consider Compliance and Industry Standards

Many industries require seals and gaskets to comply with specific standards to ensure safety, reliability, and regulatory compliance. Key standards to consider include:

• ASME B16.20: Governs metallic gaskets used in high-pressure piping applications.
• PN Ratings (e.g., PN16, PN40): Define the nominal pressure a gasket or flange can withstand in metric piping systems.
• FDA and EU Regulations: Ensure materials used in food, beverage, and pharmaceutical applications are safe and non-reactive.
• DIN and EN Standards: Common in Europe, covering gasket dimensions, materials, and performance criteria.
• API Standards (e.g., API 601, API 622): Relevant for the oil and gas industry, specifying gasket design, material, and leak performance.
• NACE Standards: Address corrosion resistance requirements, especially for chemical and petroleum industries.

Ensuring compliance with these standards helps guarantee that the selected gasket material not only meets operational requirements but also adheres to industry and regulatory mandates, reducing the risk of failures and legal or safety issues.

Step 4: Evaluate Cost vs. Performance

While it’s tempting to select the cheapest material, cost-effectiveness comes from balancing initial cost with longevity and reliability. A slightly more expensive gasket material may deliver a better whole life cost value, as it can reduce disruption, maintenance costs and downtime significantly.

By following these steps, you can confidently select the ideal gasket material for your application, minimising risk and maximising efficiency.

Key Considerations:

• Assess temperature, pressure, and chemical exposure first 
• Match the material properties to your application
• Ensure compliance with industry standards
• Balance cost with long-term performance

The following comparison table evaluates common elastomeric, fibrous, and metallic materials, such as Nitrile (NBR), EPDM, Silicone, and PTFE against some  key criteria to help you identify the most cost-effective and reliable solution for your specific application.

Choosing the correct gasket material is not just a specification decision, it directly impacts system safety, maintenance frequency, and operational cost. By evaluating operating conditions, material properties, and compliance requirements, engineers can ensure reliable sealing performance across even the most demanding applications.

In the world of logistics and warehousing, the line between operational efficiency and safety compliance can often feel like a balancing act. However, a robust safety strategy is not just about ticking boxes for the Health and Safety Executive (HSE); it is a fundamental component of a profitable, smooth-running facility.

For Warehouse Managers, Facility Maintenance teams, and Directors, understanding site safety equipment is critical. It is about more than just avoiding fines, it is about protecting your most valuable assets: your people and your infrastructure.

This guide explores the essential site safety solutions available to modern warehouses, how to mitigate common hazards, ensure legislative compliance, and ensure the safety of your teams.

The Legal Landscape and Your Responsibilities

Under the Health and Safety at Work Act and regulations enforced by the HSE, warehouse operators have a strict legal obligation to ensure the health, safety, and welfare of their employees. This includes maintaining safe passageways, managing traffic effectively, and preventing slips and trips, which remain the single most common cause of major injury in UK workplaces accounting for 31 - 33% of all injuries, at a cost of £800 million to £1.1 billion as a result of lost production and other costs. 

Failing to implement adequate safety measures can lead to severe consequences, from hefty fines to operational downtime. However, compliance does not have to be complex. By integrating targeted solutions, you can create a "safety-first" culture that aligns perfectly with business objectives.

Managing Warehouse Traffic: Forklifts and Pedestrians

One of the most critical risks in any warehouse is the interaction between heavy machinery (such as forklifts and HGVs) and pedestrians. Effective traffic management is essential to separate these two groups and control vehicle speed.

Speed Control Solutions Implementing physical speed deterrents is a proven way to enforce site speed limits. Polymax Speed Ramps offer a durable solution for controlling traffic flow. For areas requiring strict speed control (up to 5mph), the Arrow Speed Ramp provides high visibility with reflective arrows, ensuring drivers are aware of the hazard well in advance. For slightly higher speed zones (10mph), the Economy Speed Bump serves as an effective traffic calming measure for loading areas and car parks.

Vehicle Positioning and Impact Prevention To prevent vehicles from overshooting parking bays or rolling into pedestrian zones, Rubber Wheel Stops and Kerbs are indispensable. Polymax offers a range of high-visibility wheel stops and extruded rubber kerbs that can be bolted directly to concrete, providing a physical barrier that protects both the vehicle and the facility structure.

Protecting Infrastructure: Wall and Corner Guards

In a busy warehouse, accidental collisions are almost inevitable. Scuffs and impacts from forklifts or carts can cause significant structural damage over time, leading to costly repairs, and safety hazards.

Heavy-Duty Wall Protection Installing robust rubber profiles can absorb impact energy and prevent damage to brickwork and plaster. Polymax Wall Guards, such as the Double D Wall Guard or the Extruded Wall Protector, are designed to buffer vehicles and heavy goods carts. For areas with lower lighting or high traffic, Reflective Chevron Wall Guards offer the dual benefit of physical protection and increased visual warning.

Corner and Racking Protection Corners are notoriously vulnerable. Corner Protectors (including Bull Nose and Racking Corner Protectors) shield these weak points from collision damage. Additionally, High-Viz Foam Guards can be applied to sharp edges or protruding racking to prevent injury to operatives and damage to machinery.

Mitigating Slips, Trips, and Falls

While traffic accidents are high-impact, slips and trips are high-frequency. Wet or oily floors, along with trailing cables, create immediate hazards for operatives.

Anti-Slip Flooring Ensuring sure footing is paramount. Polymax PYRAMIC Matting features a raised pyramid surface that provides exceptional grip even in wet environments. For premium durability, the Chek Pro Hi Viz Yellow matting offers an oil-resistant, studded anti-slip surface that withstands heavy footfall and increases visibility, making it ideal for walkways and general warehouse flooring.

Cable Management Loose cables are a major trip hazard. Cable and Hose Protectors are a simple yet effective solution. From light-duty profiles for pedestrian walkways to Heavy Duty Cable Ramps capable of withstanding HGV loads, these products ensure that power and data cables are neatly housed and protected from damage, reducing the risk of trips significantly.

At Polymax, we regularly speak with site managers and contractors who know they must comply with UK site safety requirements, but are unsure how those duties translate into practical flooring and walkway decisions.

Safe walkways are not just a recommendation. They sit at the heart of Health & Safety at work obligations across construction sites, industrial facilities and commercial buildings. Slips and trips remain one of the most common causes of workplace injury in the UK, and in many cases the risk can be significantly reduced through correct specification and ongoing maintenance of walkway surfaces.

This article sets out the key legislation, what it means in practical terms, and how the right safety matting can help you meet walkway safety regulations UK wide.

The Legal Framework Behind Walkway Safety

Walkway safety is underpinned by several pieces of UK legislation.

The Health and Safety at Work etc. Act 1974 places a clear duty on employers to ensure, so far as reasonably practicable, the health, safety and welfare of employees and anyone affected by their operations. That includes providing safe access and egress around a site.

On construction projects, the Construction (Design and Management) Regulations 2015 - CDM 2015 - require risks to be considered from the design stage onwards. Pedestrian routes, temporary walkways and permanent flooring systems must all be assessed as part of that process.

Guidance from the Health and Safety Executive reinforces the importance of slip resistance, good housekeeping and suitable surfaces. In short, walkway surfaces must be safe, stable and properly maintained.

What UK Site Safety Requirements Mean in Practice

Across construction and industrial environments, compliant walkways should be:

• Clearly defined and, where necessary, segregated from vehicles
• Even, secure and capable of handling expected loads
• Slip resistant in both dry and wet conditions
• Maintained in good condition
• Free from avoidable trip hazards

These principles apply to everything from temporary construction site walkway safety measures through to permanent factory aisles and high level access routes.

For many sites, the challenge is balancing compliance with durability and speed of installation.

Construction Phase - High Visibility and Slip Resistance

During construction, walkways are exposed to debris, dust, moisture and heavy traffic. Under CDM 2015, these risks must be anticipated and managed.

This is where high visibility anti-slip matting plays a crucial role.

Chek PRO Hi-Viz - Defined, Durable Walkways

Our Chek PRO Hi-Viz roll has been developed for medium to heavy foot traffic in demanding environments. With an R12 slip resistance rating and strong abrasion resistance, it is well suited to construction site walkway safety where contamination and moisture are common.

The 2mm thick roll format allows for quick deployment across:

• Temporary pedestrian routes
• Welfare unit entrances
• Access corridors
• Plant and service areas

The high visibility yellow finish clearly demarcates safe walking zones, supporting effective trip hazard prevention UK wide. On busy construction sites, that visual definition is not only useful for pedestrians, it also makes designated routes far more obvious to plant and crane operators working at height, helping them quickly identify where people are likely to be moving on the ground.

Chek PRO Hi-Viz also offers strong fire performance and dimensional stability, making it suitable for enclosed site cabins and internal construction environments as well as open areas.

Because we hold stock with short lead times, contractors can implement compliant solutions quickly without disrupting project programmes.

Industrial and High Level Walkways - A Modular Approach

In operational facilities, walkways must cope with constant traffic, machinery movement and, in some cases, oils or chemicals. High level walkways introduce additional considerations around stability and long-term wear.

Easi Lok - Interlocking Strength and Flexibility

Our Easi Lok interlocking PVC tiles provide a robust, modular solution for industrial flooring and defined pedestrian lanes.

The interlocking format means:

• Installation is straightforward
• Sections can be replaced individually if damaged
• Layouts can be adapted as operations change

For sites requiring clear segregation, Easi Lok can be supplied with yellow edging pieces. This allows you to create permanent, highly visible walkway boundaries within warehouses, production lines or maintenance areas.

The textured surface provides reliable slip resistance, while the tile construction supports demanding commercial and industrial loads. For high level walkways where safety and surface integrity are critical, Easi Lok offers a stable, long-term solution.

Disabled Access and Inclusive Design

Walkway safety regulations UK wide extend beyond industrial use. Inclusive access must also be considered.

Safe surfaces should provide:

• Consistent slip resistance
• Minimal trip edges
• Clear visual contrast at boundaries and transitions

High visibility materials, whether through Chek PRO Hi-Viz rolls or Easi Lok edging, help define routes clearly for all users. Good contrast and flush transitions reduce the risk of trips and support broader accessibility obligations.

Maintenance and Post-Occupancy Responsibilities

Meeting UK site safety requirements does not end at installation.

Under the Health and Safety at Work etc. Act 1974, employers must ensure that flooring and walkways remain safe over time. That includes:

• Routine inspections
• Prompt replacement of worn or damaged areas
• Cleaning regimes appropriate to site conditions
• Reviewing risk assessments if usage changes

Both Chek PRO Hi-Viz and Easi Lok are designed with practical maintenance in mind. Roll matting can be lifted and replaced where needed, and interlocking tiles allow individual sections to be swapped without disturbing the surrounding floor.

This makes it easier to maintain compliance without extensive downtime.

Creating a Proactive Safety Culture

While legislation such as CDM 2015 sets minimum expectations, the most effective sites go further.

Clear walkway definition, high visibility demarcation and investment in durable, slip resistant flooring demonstrate a proactive approach to construction site walkway safety. They also send a clear message to staff and visitors that safety is taken seriously.

At Polymax, we see the difference that properly specified matting can make. It supports compliance, protects productivity, and sends everyone home safely at the end of the day.

Ensuring the Safety and Compliance of Materials for Potable Water

Ensuring the safety and compliance of materials in contact with drinking (potable) water is a critical responsibility for engineers, manufacturers, and contractors in the UK. The Water Regulations Advisory Scheme (WRAS) provides a robust framework to certify materials for potable water use, verifying that products will not compromise water quality, public health, or system performance.

Is WRAS Approval a Legal Requirement?

While WRAS approval itself is a voluntary certification and not a legal requirement, compliance with the Water Supply (Water Fittings) Regulations (or Scottish Byelaws) is mandatory by law.

In the context of O-rings, this means:

• The Legal Risk: Installing a non-compliant O-ring, such as a generic automotive seal, that leaches chemicals or promotes bacterial growth is a criminal offense.
• The Performance Gap: In the UK, compliance is viewed through two lenses: Safety (BS 6920/WRAS) and Reliability (EN 681-1). While WRAS ensures the water stays pure, EN 681-1 (the standard for elastomeric seals) ensures the O-ring is physically strong enough to prevent leaks and structural failure.
• The Practical Solution: Because individual homeowners and plumbers cannot easily perform laboratory tests on a single rubber seal, using WRAS-approved O-rings is the only practical way to guarantee that a component meets the required legal standards for both safety and mechanical integrity.

The regulations state that every water fitting must be of "an appropriate quality and standard." While other certifications (like KIWA or NSF) are also legally valid, WRAS remains the most recognised "stamp of approval" in the UK to ensure your plumbing stays on the right side of the law.

What WRAS Approval Ensures

WRAS certification confirms that materials and components in contact with potable water:

• Do not leach harmful substances into water.
• Maintain taste, odour, and clarity.
• Prevent microbial growth (Standardised via EN 16421).
• Retain structural integrity under normal service conditions (Standardised via EN 681).

Materials undergo rigorous testing, including:

• Chemical extraction testing: Ensures no harmful compounds migrate into water.
• Organoleptic assessment: Evaluates taste and odour impacts.
• Microbial growth testing (EN 16421 / BS 6920-2.6): Ensures the material does not provide a "food source" for bacteria. EN 16421 tests the Enhancement of Microbial Growth (EMG), preventing biofilms that could harbor pathogens like Legionella.
• Mechanical performance (EN 681-1): Verifies hardness, tensile strength, and "compression set" to ensure the seal doesn't degrade over time.

Only materials that meet all criteria are approved, providing confidence in long-term water safety for engineers, contractors, and water authorities.

Scope of WRAS-Certified Products

WRAS certification is relevant to non-metallic components in contact with potable water, including:

• Seals and gaskets
• O-rings
• Cords
• Tubing and hoses
• Sheets and linings
• Rubber mouldings

Checking WRAS Approval

• Verify that a product has a current WRAS approval mark.
• Approvals are valid for 5 years and must be re-evaluated after expiration.
• Formulations can change over time; only verified approvals ensure regulatory compliance.
• Manufacturers display the WRAS Certification Mark on packaging or websites.
• Check out the official Polymax WRAS listings on the WRAS website.

Key point: WRAS approval covers individual products or materials, not an entire manufacturer’s product range.

WRAS vs Global Potable Water Standards

Elastomer and Non-Elastomer Material Comparison

Selecting the correct elastomer or material is critical for WRAS compliance. Only chemically inert, water-stable, and microbiologically safe materials should be used in drinking water systems.

WRAS at a Glance

• Chemical safety (via BS 6920)
• Microbiological safety (via EN 16421)
• Mechanical reliability (via EN 681)
• Regulatory compliance (Water Supply Regulations 1999)

For UK potable water applications, engineers and specifiers should prioritise WRAS-approved Silicone (VMQ) and EPDM, as these consistently meet stringent testing requirements.

Tip: Always verify material WRAS status and consult technical datasheets to ensure safe, compliant, and long-lasting potable water systems.
