Entry into a confined space begins when which occurs?

• A. Any part of your body passes through the entrance
• B. The entire body enters and stays
• C. You obtain a permit
• D. An observer signs in

Answer: (A)

Entry into a confined space starts the moment any part of your body crosses the entrance boundary. Once a hand, arm, shoulder, or any other part passes through the opening, you are exposed to the space’s hazards and must follow the safety rules that apply to confined-space entry, including permit requirements, atmospheric testing, ventilation if needed, and a standby/rescue plan. You don’t need to have the entire body inside for the entry to be considered underway. Getting a permit is a necessary step before work begins, but it marks the authorization to enter, not the moment entry begins itself. Similarly, having an observer sign in is part of the safety procedure, not the defining moment of entry. And waiting for the entire body to be inside is unnecessary—the hazard exposure can start as soon as any portion crosses the boundary.
