Part 18 Personal Protective Equipment

Section 247 Selection of equipment

Respiratory protective equipment must be selected in accordance with CSA Standard Z94.4-02, Selection, Use and Care of Respirators. There are a number of factors that need to be considered when selecting the appropriate respiratory equipment:

(a) identity of the airborne contaminants;
(b) concentration of airborne contaminants;
(c) oxygen concentration in the air;
(d) physical form of the contaminant;
(e) occupational exposure limits;
(f) length of time that the respirator will need to be worn;
(g) toxic properties of the contaminants;
(h) warning properties of the contaminants; and
(i) need for emergency escape.

These same factors apply whether an employer is dealing with an airborne contaminant, typically a chemical, or an airborne biohazardous material.

More details regarding the selection of respiratory protective equipment are provided in the publication shown below.
