Respirator Selection Guide

Select a Respirator in 4 Simple Steps

One First, Identify the Contaminants You're Dealing With

The primary source of information on a chemical's state and physical form is the Material Safety Data Sheet(MSDS). The MSDS may also make recommendations for what type of respirator may be needed to work safely with the product. Once the potential contaminants are identified, air sampling should be done to determine how much of the contaminant is likely to be present in a work shift.

Two Then, Test Your Environment

Air Sampling can be performed by a consulting firm or by OSHA Consultation. This evaluation should include a reasonable estimate of emplyee exposures to respiratory hazards and an identification of the contaminant's chemical state and physical form.

Once the contaminant level is established, you should investigate effective hazard control methods, such as engineering and administrative controls, before resorting to a respirator. If you do need a respirator, our Certified Safety Professionals can help you make the appropriate choice. Email them now.

If the employer cannot identify or reasonably estimate the employee exposure, the employer shall consider the atmosphere to be IDLH(Immediately Dangerous to Life and Health).

Three Next, Choose a Level of Protection

Select a filter that is designed to remove air-borne particulates which may be harmful to the lungs in your workplace. Particulates which may be blocked by a filter include dust,fumes(metal particles from welding),fibers and mists. Dry particulates can be removed with an N95, N99 or N100 filter. Dry or Oily particulates can be removed with and R95, R99, P95, P99 or P100 filter. See our Respirator FAQ for more specifics.

You may even need a cartridge and a filter, depending on the nature of your work. Cartridges contain activated carcoal which can be chemically treated to remove various gases and vapors. We have several types of cartridges to select from. Certain chemicals will not be blocked by the cartridges and you may need to consider a supplied air system.

Four Finally, Size Your Respirator

A mask must fit properly and be fit tested to ensure complete protection. It should have a tight seal around the nose and mouth to prevent leakage. We offer a complete line of fit test kits to assist you with this process. Remember that all persons who wear respirators for a chemical hazard must conform with the OSHA requirements, which includes fit testing and medical evaluations.
