A fire has been reported in the ship's laundry room. As Chief Engineer you direct the team leader of the #1 emergency squad to secure ventilation to the space. What would your next command be to the emergency team leader, before they can actually start extinguishing the fire?

Correct Answer: Option B — Have electrical power secured to the laundry room. A lock-out tag should be placed on the breaker or switch stating the circuit has been de-energized, to protect crew members from electrical shock.

Laundry rooms house high-amperage electrical washers and dryers. Securing power and applying formal lockout/tagout procedures to the breaker panel is a strict safety prerequisite to prevent accidental re-energization and protect personnel from severe electrical shock during firefighting.
