What must an individual be to wear a respirator effectively?

To wear a respirator effectively, it is essential for an individual to be clean-shaven. This is because respirators rely on a tight seal against the skin to function properly, preventing any contamination from entering through gaps. Facial hair, such as a beard or mustache, can compromise this seal, leading to potential exposure to hazardous materials, including lead dust or particulates.

While glasses may be worn with certain types of respirators, they should be compatible and not interfere with the mask's fit. Similarly, cosmetics and facial hair can hinder the effectiveness of the respirator's seal. The emphasis on being clean-shaven highlights the importance of proper fit for ensuring the safety and protection that respirators are designed to provide.
