Which of these statements about respirators is true?

The statement regarding the necessity to be fit-checked to a specific respirator is accurate because proper respiratory protection requires that each individual be fitted for their specific model. A fit check ensures that the respirator forms a proper seal around the face, which is critical for the respirator to function effectively. If the respirator does not fit well, contaminants can bypass the filter, leading to inadequate protection.

This is particularly important in various workplaces, including healthcare settings, where exposure to airborne pathogens can pose serious health risks. The fit-testing process typically occurs before the respirator is first used and is usually repeated periodically to account for changes in the user’s facial structure or weight.
