When should respirators be checked for safety?

The correct answer is that respirators should be checked for safety before each use. This practice is essential because respirators are critical personal protective equipment (PPE) that help protect individuals from inhaling hazardous substances in the air. Conducting a safety check before each use ensures that the respirator is in proper working order, which includes checking for any signs of damage, ensuring a proper fit, verifying that filters and cartridges are appropriate for the task, and determining that the overall equipment is clean and functional.

Regular checks help to identify any potential issues that may compromise the effectiveness of the respirator and protect users from exposure to harmful chemicals or other airborne contaminants. This proactive approach is crucial, particularly in environments where air quality may pose immediate risks.

Other options suggest less frequent checks, such as monthly or only during annual inspections, which could leave users exposed if the respirator fails or is not functioning properly. Additionally, checking after every use does not address the need for ensuring the equipment is ready and safe before the next use. Such practices can lead to complacency and inadequate safety measures in environments with hazardous air contaminants.
