- Fire tetrahedron
- A model of fire that includes fuel, oxygen, heat, and the chemical chain reaction. Removing any one element extinguishes the fire.
- Flashpoint
- The lowest temperature at which a liquid releases enough vapour to form an ignitable mixture with air near its surface.
- Lower explosive limit
- The minimum concentration of vapour in air below which the mixture is too lean to ignite. Also called lower flammable limit.
- Spontaneous combustion
- Self-heating of materials such as oily rags or coal that leads to ignition without an external heat source, caused by oxidation.
- Hot work permit
- A formal authorisation required before welding, cutting, or grinding. It ensures fire precautions, gas-free conditions, and a fire watch are in place.
- Gas-free certificate
- A document confirming that a space has been tested and found free of flammable or toxic gases before hot work or entry.
- Bonding and grounding
- Connecting equipment to equalise electrical potential and to earth, preventing static sparks during fuel transfer or tank cleaning.
- Fire door wedged open
- A violation of fire safety; fire doors must be kept closed to prevent fire and smoke spread through the ship.
- Rate-of-rise detector
- A heat detector that activates when the temperature increases faster than a predetermined rate, indicating a growing fire.
- Photoelectric smoke detector
- A detector that uses a light beam and sensor to detect smoke particles scattering light. It responds well to visible smoke from smouldering fires.
- Fixed CO2 system
- A total flooding system that discharges carbon dioxide to displace oxygen. It requires evacuation and headcount before release.
- General emergency alarm
- Seven or more short blasts followed by one long blast on the ship's whistle and alarm, signalling all crew to muster.
- Water extinguisher
- An extinguisher containing water, suitable for Class A fires (wood, paper, textiles). Never use on electrical or flammable liquid fires.
- CO2 extinguisher
- An extinguisher that smothers fire by displacing oxygen. Suitable for electrical and flammable liquid fires; leaves no residue.
- Storz coupling
- A symmetrical, quick-connect hose coupling with interlocking lugs. It allows fast connection without regard to orientation.
- SCBA
- Self-contained breathing apparatus. It provides breathable air from a cylinder, allowing firefighters to work in smoke-filled spaces.
- Boundary cooling
- Applying water spray to adjacent bulkheads and decks to absorb heat and prevent fire from spreading to neighbouring compartments.
- Ventilation control
- Closing doors, hatches, and vents to limit oxygen supply to a fire and to prevent smoke spread through the ship.
- Indirect attack
- Using fog or spray from a protected position to cool hot gases and reduce flashover risk before making entry.
- Class A fire
- Fire involving solid combustibles such as wood, paper, and textiles. Extinguish with water, foam, or dry powder.
- Class B fire
- Fire involving flammable liquids such as oil, petrol, or paint. Extinguish with foam, CO2, or dry powder; never use water jet.
- Class C fire
- Fire involving flammable gases such as LPG or methane. Extinguish with dry powder or CO2; shut off gas supply if possible.
- Class D fire
- Fire involving combustible metals such as magnesium or sodium. Extinguish with special dry powder; never use water, foam, or CO2.
- Class E fire
- Fire involving live electrical equipment. Extinguish with CO2 or dry powder after de-energising if possible.
- Muster station
- A designated safe assembly area on board where all crew report upon hearing the general emergency alarm.
- On-scene leader
- The officer in charge of firefighting operations at the scene, usually the Chief Officer or Chief Engineer, reporting to the Master.
- Muster list
- A document posted on board showing each crew member's assigned duty and station during an emergency.
- Fire control plan
- A ship's diagram showing the layout, firefighting equipment, and escape routes, available at the bridge and outside accommodation.
- Entry control point
- A designated location where a supervisor records firefighters entering a space, their air supply time, and maintains communication.
- SCBA cylinder pressure
- The pressure of air in the SCBA cylinder, which must be at least 80% of full capacity before use.
- Fire scene preservation
- The practice of not disturbing a fire scene until investigation is complete, to allow determination of origin and cause.
- Fire report
- A document detailing the time, location, cause, extinguishing methods, and damage of a fire, used for investigation and insurance.
