What is the effect of not adhering to proper respirator fit testing?

Not adhering to proper respirator fit testing primarily increases the risk of exposure to hazardous substances, such as asbestos fibers. Fit testing ensures that the respirator creates an adequate seal around the user's face, which is crucial in preventing air contaminants from entering the breathing zone. If a respirator does not fit properly, it may allow unfiltered air to bypass the filter and enter the mask, significantly reducing its effectiveness. This can lead to unintended inhalation of harmful particles, thus compromising the user’s health and safety.

While reduced comfort, higher costs, and limited training opportunities may also be issues associated with improper respirator use or fit, they are secondary to the main concern of safety. The primary goal of respirator fit testing is to ensure that users have a reliable barrier against dangerous airborne substances, emphasizing the importance of adherence to fit testing protocols to protect health.
