In regulated areas, what must be done for workers exposed to a substance with a specific standard?

• A. Monitored and protected
• B. Monitored and trained
• C. Monitored but not protected
• D. Protected but not monitored

Answer: (A)

Exposures to regulated substances must be both measured and controlled. Monitoring checks the actual level of a worker’s exposure to ensure it stays within allowable limits, while protection reduces that exposure through engineering controls, proper work practices, and appropriate PPE. These two elements work together to keep workers safe; without monitoring you wouldn’t know if exposure is acceptable, and without protective measures you could still be harmed even if a standard exists.
