What respirators do not require fit testing?

Respirator fit testing

Fit testing should not be confused with user seal inspection. A user seal inspection is a quick check performed by the same person who wears the respirator each time the respirator is donned. Determine if the respirator is correctly positioned on the face, or if the respirator needs to be readjusted.

Qualitative fit tests are commonly used for half-mask respirators-those that cover only your nose and mouth. Half-mask respirators can be filtering facepiece respirators, often called N95s, as well as elastomeric respirators.

Many workers must wear prescription eyewear or personal protective equipment, such as safety glasses or earmuffs, while working. If you are one of them, you should wear those items during the fit test to make sure they do not interfere with the fit of the respirator.

Remember, if you don’t know if you need a respirator for your tasks, or if you are unsure about how to properly wear a respirator, or about which filter or cartridge to use, talk to your supervisor before entering the hazardous area.

Some employers and consumers are considering the purchase of escape hoods or other respirators to protect against potential terrorist threats, including those related to biological and chemical substances. This guidance page will provide information on what respirators are, how they work, and what is needed for a respirator to provide the desired protection.

Respirator with gas mask or chemical cartridge Gas masks are also known as “air-purifying respirators” because they filter or clean the air of chemical gases and possibly particles as you breathe. This respirator consists of a facepiece or mask that covers the face and a filter or cartridge (if the filter is in a metal canister, it is called a “canister”). Straps secure the mask to the head. The cartridge may have a filter to extract particles (as in the case of a biological weapon), charcoal (to extract certain chemicals), both or other components. When the user inhales, it forces air through the filter.

Types of respirator filters

Half-mask respirators can be filtering facepiece respirators, often called “N95s,” as well as elastomeric respirators. Quantitative fit testing uses a machine to measure the actual amount of leakage in the facepiece and does not rely on your sense of taste, smell or irritation to detect leakage.

In other work areas, usually construction-related, respirator fit testing is required to protect employees from dirt, dust, sand, toxic chemicals, etc. Employees can have serious health problems if they are exposed to contamination and do not have the means to adequately protect themselves.
