If a person smells or tastes a chemical while wearing a respirator, what should they do?

When a person smells or tastes a chemical while wearing a respirator, it indicates that the respirator is not providing adequate protection against that substance. This situation suggests that the respirator may not have an effective seal, that it is the wrong type for the hazard present, or that the filter is saturated or damaged, which can result in significant inhalation exposure to harmful chemicals.

Changing the respirator immediately is the appropriate action to ensure safety. Doing so prevents further exposure to potentially hazardous chemicals that can lead to health complications. The objective of a respirator is to block harmful particles and gases from being inhaled; therefore, if any leakage or failure to filter is detected, it is essential to replace it right away.

Continuing to use the same respirator could lead to serious health risks, and taking a break may not adequately mitigate exposure to the chemicals involved. Seeking medical attention, while important if there has been exposure, does not address the immediate need for effective respiratory protection.
