Who should be aware of all hazards and convey emergency procedures during explosive operations?

• A. Casual
• B. Supervisors
• C. Visitors
• D. Commanders

Answer: (B)

In explosive operations, the supervisor is the on-site point person responsible for knowing all hazards and conveying emergency procedures to the crew. They have direct oversight, authority to halt work if conditions are unsafe, and the duty to brief everyone on potential hazards, controls, and the exact steps to take during an emergency. This ensures clear, consistent communication and a rapid, coordinated response if something goes wrong. Casual personnel or visitors may receive general safety information, but they aren’t the designated on-site hazard communicator. Commanders set overall safety direction, but the day-to-day hazard awareness and emergency briefing on the job site rests with the supervisor.
