What should workers do before using respirators in an emergency?

Before using respirators in an emergency, it is essential for workers to familiarize themselves with how the respirator operates, conduct a risk assessment, and ensure they have been fit-tested for the respirator. Each of these actions plays a critical role in ensuring the safety and effectiveness of the respiratory protection equipment.

Familiarizing oneself with the operation of the respirator allows workers to understand how to properly wear and use the equipment, including how to adjust straps for a secure fit and how to perform checks for proper seal and functionality. This knowledge is vital in high-stress emergency situations where proper usage can directly impact safety.

Conducting a risk assessment helps identify hazards present in the environment that may require respiratory protection. Understanding the types and concentrations of contaminants enables workers to determine the appropriate type of respirator needed to protect their health. This proactive approach is crucial in emergency scenarios where conditions may change rapidly.

Fit-testing is another critical step. It ensures that the respirator has a proper seal on the face, which is necessary to prevent exposure to hazardous substances. A poorly fitting respirator can allow contaminated air to leak in, negating the effectiveness of the protective device. Regular fit-testing is essential for maintaining safety standards and ensuring that the respirator will function as intended when
