Respiratory Protective Equipment
Respiratory protective equipment (RPE) protects the individual from inhalation of hazardous substances. These can be particles such as solids, liquids and radioactive material or gases, vapours and micro-organisms that pose a threat to health either in the short or long term. They can also include contaminants from work activities in confined spaces, scrubbing of contaminated surfaces and air deficiency due to oxygen depletion or lack of sufficient ventilation.
There are two basic types of RPE. Particulate or “dust masks” remove airborne particles from the atmosphere and chemical and gas respirators filter out chemicals and gases. These can be powered or unpowered. Non-powered respirators are often referred to as “non-powered breathing apparatus” and use a filter that requires the user to pass air through it using a breathing hose from an independent source of clean, respiratory-quality air. These include a variety of facepieces from tight-fitting to loose-fitting and can have hoods or helmets.
Respiratory Protective Equipment: Types, Uses, and Benefits
When selecting RPE, employers must consider the work to be performed, the duration of the activity and other personal factors such as facial hair and scars. The contaminant to be controlled, its chemical state and physical form, as well as the ability of the worker to wear the chosen RPE must also be evaluated. The RPE selected must be NIOSH-certified and the user must undergo a medical evaluation and a fit test to ensure that the respirator is a good fit for them. A record of all evaluations, medical and fit testing as well as training must be maintained by the department. The Respiratory Protection Office can assist with these activities including providing an exposure evaluation, model written programs and training for employees who will be required to wear a respirator or use a respirator voluntarily.…
