If the fire is small and there is not too much smoke, tackle the fire with a suitable extinguisher. In machinery spaces, there is high voltage electricity so try to isolate the circuits. For this type of fire, use dry powder or CO2.
Isolation is crucial in machinery space fires: isolate oil and diesel valves and switch off the pumps that feed them. Use the panel by the emergency generator or in the alleyway.
Firefighting conditions are difficult in such spaces. Access is confined and temperatures can be very high. Using water in these conditions creates a great deal of steam and high levels of humidity. BA activity in these conditions must be strictly controlled to avoid the effects of heat and humidity.
Hydrocarbon fires rapidly produce high temperatures and high levels of radiated heat from the flames. Entry must be made from as low down as possible and partial ventilation maintained to remove heat and humidity as long as people remain inside.
Evacuate unnecessary crew members from the machinery space. From the engine room, this will often involve using the escape trunking. Use the protected escape route rather than the normal vertical routes. Smoke and heat rise creating greater dangers the higher you go. Even so, wear 10 minute escape hoods for extra protection, where provided.
Once the engine room personnel are safe, close off engine room ventilation fans that may feed the fire with air.
It is essential that everyone goes to their muster station. The first task of the Officer in Charge is to carry out a roll call. If someone is missing, injured, or trapped, a search and rescue party, equipped with breathing apparatus, must go in to find them.
