Which of the following is NOT a recommended practice before using a respirator?

Using a respirator without proper training is not a recommended practice because training ensures that the individual understands how to properly use, maintain, and wear the respirator. Proper training equips workers with knowledge about the specific types of respiratory hazards they may encounter, how to correctly don and doff the respirator, and the importance of performing checks like seal tests and fit checks. These practices are essential for ensuring the respirator functions effectively and provides adequate protection.

Conversely, performing a seal check, inspecting for damage, and ensuring proper fit are all critical pre-use practices designed to maximize safety and effectiveness while using a respirator. Engaging in these actions helps to confirm that the respirator is not only functioning correctly but also that the wearer will receive the intended level of protection against airborne contaminants.
