Which safety measure should be posted at all entries to a confined space?

• A. PPE
• B. Signage
• C. Lighting
• D. Barriers

Answer: (B)

Posting signage at every entry to a confined space is essential because it immediately communicates that the space is hazardous and may have permit requirements, warns about potential hazards, and identifies who is authorized to enter. This visible notice helps prevent unauthorized or unprepared entry and guides workers and responders to follow the proper procedures before and during entry. PPE, while crucial for protection inside the space, is about what to wear, not the warning itself. Lighting and barriers support safety, but they don’t provide the clear, standardized warning at the entry that signage does.
