Respiratory protective equipment keeps workers safe in environments where they’re routinely exposed to hazardous airborne particles. It’s designed to provide a barrier between the workers faces and substances in the air, but even with the best equipment, if the fit isn’t right then then it’s unlikely to work. That’s where face fit testing comes in – a process that ensures RPE does exactly what it’s supposed to do: protect.

At its core, face fit testing is about ensuring a proper seal between the mask and the wearer’s face. No two faces are the same. Differences in face shape, size or even facial hair can affect how well a mask fits. A poorly fitting mask allows contaminants to bypass the filter and be inhaled by the wearer, rendering the RPE ineffective. Face fit testing helps to identify whether a specific mask will work for a specific person and keep them protected at all times.

You might be wondering, why go to such lengths for a mask? The truth is, exposure to airborne contaminants can have serious life-threatening consequences. From silicosis to occupational asthma, the long-term health risks of inhaling harmful particles are significant. Face fit testing isn’t just about ticking boxes for health and safety; it’s about safeguarding the well-being of employees. Employers have a duty of care to make sure their workforce is protected and face fit testing is a key part of meeting that responsibility.

So when should face fit testing be performed? Ideally, every time new RPE is introduced or when there are changes that could affect the fit, like weight loss, dental work or new facial hair. It’s also important to test periodically to account for natural changes in the face over time. While a mask may fit perfectly when first issued, that fit could deteriorate months later without anyone realising. Regular testing verifies that the equipment continues to provide the necessary level of protection.

There are two types of face fit testing commonly used: qualitative and quantitative. Qualitative testing is a simpler method, often involving the wearer identifying certain tastes or smells to assess whether the mask is leaking. This is generally suitable for half masks, such as disposable masks or reusable half masks. Quantitative testing, on the other hand, is more precise. It uses specialised equipment to measure the amount of contaminant particles that enter the mask, providing an exact numerical fit factor. This method is typically used for full-face masks or when a higher level of accuracy is needed.

For businesses in the West Midlands, face fit testing is a must. The region is home to a wide range of industries where exposure to airborne hazards is common. By investing in proper testing, businesses can avoid fines and legal proceedings, and become compliant with health and safety regulations. More importantly, it demonstrates a commitment to their employees’ health. It’s not just about following the rules, but about doing what you can to protect your workers.
