What are the requirements for anyone using an air purifying respiratory?

To be trained and certified only
To be medically certified, fit tested, and trained
To have received safety training
To be supervised while using the device

The correct answer is: To be medically certified, fit tested, and trained

Using an air purifying respirator requires individuals to be medically certified, fit tested, and trained to ensure their safety and the effectiveness of the device. Medical certification is essential because it ensures that the user does not have any underlying health conditions that might be exacerbated by wearing a respirator. Fit testing is crucial to confirm that the respirator properly seals to the user’s face, providing adequate protection against airborne contaminants. Lastly, training equips users with the knowledge on how to properly use, maintain, and recognize when a respirator may not be working effectively. This combination of requirements ensures optimal performance and safety for individuals working in environments where airborne hazards exist.
