Dust & Face Masks

Not using a dust respirator in a industrial environment has been linked to disease and even death, so using the correct mask for the hazard identified under a risk assessment is paramount.

Choosing the right level of dust mask protection

Dust masks need to meet European standard EN149:2001. This directive specifies three levels of protection; P1, P2 & P3.

Face mask protection is classified as basic, medium & high.

• Basic protection. FFP1 filters 80% of particles & is appropriate for low levels dusts & mists. Not considered sufficient protection for most tasks & rarely seen in the market.
• Medium protection. FFP2 masks offer 94% protection from particulate matter such as that generated by metal working, sanding & drilling and are a minimum requirement for those tasks.
• High protection. FFP3 offers 99% protection & is recommended for welding, biohazard agents, hazardous chemicals and radioactive elements.

Choosing between valved & non-valved dust masks

• Valved masks offer more comfort & great for hot environments or where fogging of glasses may occur. Excellent for all day use with exhalation via the valve.
• Un-valved masks offer two way protection, protecting those around you from your exhalation. Generally a tighter fit.

Dust mask Fit testing requirements 

You should carry out a fit test for your Respiratory Protective Equipment(RPE). Ensuring you have the proper fit will keep you safe while at work. It will also reduce humidity, so that your goggles don't fog up and make it hard or impossible to see. All masks are adjustable to fit any face shape or size, so use the head straps and nose clip to create a tight seal. The mask is essentially useless if airborne particles can sneak in the sides.

The HSE is clear in it's message when it comes to the fit testing of tight fitting face pieces(masks). In summary they expect the following.

• The dust mask must be matched to the work environment. Cross check with COSHH & MSDS sheets to make sure you're adequately covered.
• The test must be undertaken undertaken by a competent person. Foster Industrial can organise this for you.
• Tests must specify; Name of person, the model of mask, date, pass level, date, person carrying out the test etc.
