Which statement best describes OSHA's stance on safety in confined spaces?

• A. Confined spaces are always safe with no precautions
• B. OSHA requires safety measures but does not guarantee 100% safety
• C. OSHA bans all work in confined spaces
• D. OSHA requires only PPE for confined spaces

Answer: (B)

The key idea here is that protecting workers in confined spaces relies on a planned safety program with concrete controls, but cannot promise absolute safety. OSHA’s approach requires a permit-required confined spaces program: identify and evaluate hazards, continuously monitor the atmosphere, isolate or purge the space, implement an entry permit system, provide trained entrants and attendants, ensure proper ventilation and equipment, and have a rescue plan ready. Even with these precautions, conditions can change unexpectedly—there can be delayed gas releases, oxygen levels can shift, or procedures may not go exactly as planned—so OSHA stops short of promising 100% safety. PPE is part of the toolbox, but it isn’t the sole solution; controlling the space through procedures, engineering controls, and precautions is essential. That’s why the statement that OSHA requires safety measures but does not guarantee 100% safety best captures OSHA’s stance.
