Which statement about re-entry is true?

• A. Re-entry is safe if you can see no flames.
• B. Re-entry is allowed only after clearance; otherwise hazards exist.
• C. Re-entry is never allowed.
• D. Re-entry should be rushed.

Answer: (B)

Entering back into a fire or hazardous area must be a controlled action that is cleared by incident command and verified as safe before anyone goes in again. The essential point is that safety isn’t guaranteed by what you can see—no flames doesn’t mean the environment is safe. Hidden dangers like toxic smoke, high heat, oxygen depletion, or structural instability can persist even after flames are out. Clearance involves a thorough check: atmospheric testing for oxygen and contaminants, structural assessment, and confirmation that safeguards and rescue plans are in place. Only after this clearance is given should re-entry occur. This is why that statement is correct: re-entry is allowed only after clearance; otherwise hazards exist.
