Description

A respiratory protective equipment is meant to protect a person against hazardous substances present in the atmosphere where he/she should work under forms like solid or liquid aerosols or gas, vapours or steam.

The user of a respiratory protective equipment must know the nature of the present risks (composition and concentration of the toxic substances) in the atmosphere in which he/she should work on one hand, and the performance level and limits of the respirator on the other hand. It’s important to take into consideration the time during which the protection must be ensured as well as the physiologic charge (breathing rhythm) of the user in order to select a respirator having the adapted autonomy.

The Occupational Exposure Limit values are the levels of toxic contaminants to which an unprotected worker may be exposed during a given period without adverse health effects. Are distinguished the Long Term Exposure Limit (LTEL for exposure to an 8-hour period) and the Short Term Exposure Limit (STEL for exposure to a 15-minute interval).

These values depend on national legislations.
