What is required before using any respirator on the job?

Before using any respirator on the job, it is essential for the worker to complete a fit test for the mask. This fit test ensures that the respirator forms a proper seal on the wearer's face. A good seal is crucial because it prevents harmful airborne contaminants from bypassing the respirator and entering the worker's breathing zone.

The fit test will identify the appropriate size and style of respirator required for the individual worker, taking into account factors such as facial hair or other conditions that might affect the mask's effectiveness. Without proper testing, even the best respirator can fail to provide adequate protection, leading to potential exposure to hazardous substances.

Other options do not meet the safety standards typically required in the workplace. Specialized training certification, while beneficial, does not directly address the fit and seal essential for respirator effectiveness. Using any available mask is unsafe because not all masks are designed for the same hazards. Simply reading the user manual is insufficient for safe operation; practical fit testing is necessary for optimal protection.
