What should you do before changing a filter or cartridge while using a respirator?

Before changing a filter or cartridge while using a respirator, it is essential to always leave the respirator use area first. This practice is crucial because respirators are used in environments where there may be hazardous airborne contaminants. By leaving the area, the individual minimizes the risk of exposure to those contaminants during the filter or cartridge change.

Additionally, the act of changing a filter or cartridge could potentially release trapped contaminants, which poses a risk to the user if done in a contaminated area. Therefore, ensuring that the change is made in a safe environment protects the individual’s health and safety, making it a fundamental part of proper respirator usage protocols. This safety measure aligns with OSHA guidelines to prevent inhalation of harmful substances while maintaining effective respiratory protection.
