Life-saving and fire-fighting readiness in sub-zero temperatures
What is being checked
The inspector is checking whether winterisation procedures and repeated onboard checks keep life-saving appliances, fire-fighting systems, escape routes and emergency equipment immediately operable at the lowest expected temperature.

0/7 completePractice questions
Answer aloud, then open the preparation point.
1Where are the lowest drain points for the deck fire and foam mains?
Identify them physically and explain the drain, verification and reclosing sequence that leaves the system ready for immediate use.
2How will this lifeboat engine start at the forecast temperature?
Show the correct fuel, battery condition, heater use, oil or cold-start instructions and a recent cold-weather readiness check.
3What prevents the lifeboat spray or cooling system from freezing?
Explain the fitted drain, antifreeze or heating arrangement and show its verified status.
4What happened to water or foam extinguishers exposed on deck?
Confirm their rated temperature is suitable or show how they were relocated and replaced by an appropriate extinguisher at the required position.
5How are eyewash and decontamination arrangements maintained?
Describe the heating, relocation or other approved measure that provides usable fluid without creating a freezing injury risk.
6How often are safety systems checked during exposure?
State the risk-based interval and show time-stamped rounds that cover operability, ice removal and failed heating or protection.
Where an observation may arise
The procedure or checklist did not identify LSA and FFA systems vulnerable to the expected temperature.
Water remained in an unheated fire, foam, water-curtain or spray-system dead leg, or a hydrant or monitor could not be operated.
Ice accretion, unsuitable fuel, weak batteries, frozen doors or undrained systems prevented immediate use.
A liferaft, extinguisher, hose, protective aid or other item was not suitable for the lowest expected temperature.
Temperature-sensitive emergency equipment was relocated but the required station was left without equivalent protection.
Trace heating, insulation or a space heater relied upon instead of draining was defective or not monitored.
Snow or ice obstructed an escape route or access to fire-fighting or life-saving equipment.
Master's practical note
Test the weakest point in each protection chain. A warm machinery space does not prove that an exposed release pin, drain pocket, fire nozzle or lifeboat door will move at the forecast temperature.
Equipment boundary and references
Equipment boundary: This conditional question applies where ice class, winterisation class, a Polar Ship Certificate or routine sub-zero trading is declared. Follow maker limitations and the vessel's approved arrangements where heating replaces draining.
