The degree of worker risk from the exposure to any given substance does not depend on the magnitude and duration of exposure. The position of workers and the organization of their tasks should be appraised in view of the location and nature of the contaminant sources. THE UNIVERSE OF AIR CONTAMINANTS "Air contaminant" and "air pollutant" are terms frequently mentioned in state and federal air quality regulations. Official websites use .gov These include*: To determine IDLH level of a contaminant, consult the NIOSH Pocket Guide to Chemical Hazards. 7. 3. Without a complete respiratory protection program, workers will not receive the best protection from a respirator even if it is the correct choice for a specific job.

Each, however, has its own drawbacks, and all these factors should be taken into account during selection. Quantitative evaluations of airborne constituents may be performed for a number of reasons, for example: to assess workers exposure in relation to an adopted standard, to determine the need for control measures or to assess the effectiveness of control strategies. In order to select an appropriate respirator you must: Employers must characterize the nature and magnitude of employee exposures to respiratory hazards before selecting respiratory protection equipment.
