A safe and healthful workplace includes hazards removed and workers trained. What else is included?

• A. When hazards cannot be removed completely, protection such as respirators or earplugs must be provided.
• B. It requires no training if hazards are removed.
• C. It requires only verbal warnings, not PPE.
• D. It requires only signage with no training or PPE.

Answer: (A)

When hazards cannot be removed completely, protection such as respirators or earplugs must be provided to keep workers safe. This reflects the layered approach to workplace safety: first try to eliminate or control hazards, and if some risk remains, supply appropriate personal protective equipment and train workers on how to use it correctly. PPE is needed because warnings alone or signage don’t reduce exposure, and training is still required even if some hazards are removed to ensure workers know how to stay protected.
