It  is important that respirators are used and maintained properly. If not, they can be ineffective in controlling the hazard and in some cases do more harm than good.

Like most types of personal protective equipment, respirators should be the last choice in controlling a hazard. It is important that the hazard be thoroughly evaluated and the hierarchy of controls considered before assigning a respirator. OSHA has standards for the use of respirators that include 1910.134 for general industry and 1926.103 for construction.
If it is determined that respiratory protection is necessary, it is important that procedures are followed. These may include:

• A medical determination should be made that the user is physically able to wear a respirator. A pulmonary function test is often used to help in that determination. This should be repeated annually or whenever there is a change in production or medical status.
• The employee must be trained in the chemicals or contaminants he/she may work with and how to best control exposures that may include respiratory protection.
• The respirator(s) chosen is appropriate for the hazard. This may include an N95 respirator (dust mask), dual cartridge respiratory, PAPR, or air suppled respirator, etc. Filters should be included that control exposures to particulates, organic vapors, acid gas or other chemicals.
• The wearer should be tested for fit on each assigned respirator. This may include a qualitative or quantitative fit test depending upon the hazard and the type of respirator.
• Respirators should be cleaned after use and stored in a dry/clean location, free from contaminants. Replacements for one-time use respirators should be available.
• It should be determined how often a respirator and/or filter cartridges should be changed and a log kept on the dates when this occurs.
• The wearer should check the respirator to determine that it is not deformed and that all valves and straps are in place.
• Facial hair that interferes with the seal of respirator is not allowed.
• Supervision should regularly check respirator users to determine that these procedures are followed.

Select and maintain respiratory protection when needed. It can help protect your health.
