FFP1: Protection against non-toxic solid and liquid aerosols up to 4.5 x O.E.L. (Occupational Exposure Limit), or 4 x APF (Assigned Protection Factor).
FFP2: Protection against non-toxic and low-to-average toxicity solid and liquid aerosols in concentrations up to 12 x O.E.L., or 10 x APF.
FFP3: Protection against non-toxic, low-to-average toxicity and high toxicity a solid and liquid aerosols (e.g. oil mists) in concentrations up to 50 x O.E.L., or 20 x APF.
You should conduct a risk assessment to decide on the level of protection required, and this is dependant on the contaminant concentration. |
