Which of the following statements is true about respiratory protective equipment (RPE)?

1. It must be worn at all times

2. It will only be effective if it fits the wearer's face

3. It can be shared among workers

4. It is sufficient to wear it occasionally

The correct answer is: It will only be effective if it fits the wearer's face

The statement regarding respiratory protective equipment (RPE) being effective only if it fits the wearer's face is crucial because the primary function of RPE is to create a seal around the face to protect against airborne hazards. If the equipment does not fit properly, it cannot effectively filter out harmful substances, which compromises the safety of the wearer. Proper fitting ensures that the RPE will function as intended, maintaining a protected environment by preventing inhalation of dust, gases, vapors, and other contaminants that could cause health issues over time. In contrast, the other statements present misconceptions about RPE usage. For example, while it is vital to wear RPE in certain situations, suggesting it must be worn at all times does not consider the specific conditions or risks present. Additionally, RPE should not be shared among workers due to hygiene and individual fit requirements; what fits one person comfortably may not fit another, leading to inadequate protection. Lastly, suggesting that occasional use is sufficient undermines the protective purpose of RPE, as exposure to harmful substances can occur at any time, necessitating consistent and proper use when required.
