Which statement best describes permit-required entry vs risk-based entry?

• A. Risk-based entry adapts to hazards based on ongoing assessment
• B. Permit-required entry uses formal authorization and controls
• C. They are the same
• D. Permit-required entry is the only valid approach

Answer: (B)

Permit-required entry rests on a formal authorization process that requires an entry permit and clearly defined controls before anyone enters. This means hazards are identified, isolation and testing are confirmed, and specific procedures and supervision are in place to ensure safe entry and immediate rescue if needed. That formal permit and its documented controls is the hallmark of permit-required entry.

Risk-based entry, by contrast, is about adapting to hazards as conditions change, using ongoing hazard assessment to guide controls rather than relying on a single, formal permit with fixed requirements. This is why the statement describing permit-required entry focuses on formal authorization and controls, making it the best description of that approach.

The idea that they are the same is incorrect because the two approaches handle authorization and controls differently. And saying permit-required entry is the only valid approach isn’t accurate in all contexts, since different regulatory frameworks allow risk-based or alternative entry strategies when appropriate.
