With the sprinkler system and air system on, and all hatches shut, the survival craft will be protected from __________.

Correct Answer: Option B — a fire and toxic environment

Totally enclosed survival craft feature external water spray systems and compressed air supplies. These systems create a protective envelope, preventing heat transfer and the ingress of smoke or toxic gases, allowing the craft to transit through fire-affected waters safely as mandated by SOLAS and USCG equipment standards for life-saving appliances.
