Which of the following is stated as a precaution when donning the PBE?

• A. The neck seal must not be damaged when putting on the PBE
• B. The neck seal can be damaged if mishandled
• C. The neck seal is optional during use
• D. The neck seal should be adjusted after use

Answer: (A)

Protecting the seal around the neck is essential when donning a PBE because it creates the barrier that keeps contaminated air from entering the breathing zone. If the neck seal is damaged during putting on the equipment, leaks can form and the PBE may fail to provide the intended protection. That’s why the instruction emphasizes that the neck seal must not be damaged as you put on the suit. To follow this precaution, handle the PBE gently, inspect the neck seal for tears or wear before donning, and smooth the hood into place without pulling or snagging the seal on jewelry, rough edges, or sharp objects. The idea isn’t that damage is acceptable or that adjustments after use are the goal; instead, maintaining an intact, properly seated neck seal during donning is the key safeguard for effective protection.
