How should a supervisor warn an operator about the presence of a confined space? By clearly posting the appropriate ____________ at all entries to a confined space.

• A. Signage
• B. Warning labels
• C. Barricades
• D. PPE requirements

Answer: (A)

Communicating a confined-space hazard at the entry is essential for safety. The supervisor should post clear signage at all entries to a confined space. Signage immediately informs anyone approaching that a confined space is present and may require a permit or specific procedures, helping prevent unauthorized or unprepared entry. Other options don’t provide the same broad, initial warning: warning labels are tied to specific equipment or hazards inside, barricades can block access but may not convey the hazard or permit requirements, and PPE requirements describe protection but don’t reliably warn entrants about the space itself. Durable, legible signage at every entry ensures workers know to obtain authorization and follow the proper procedures before entering.
