Methods of Fire Extinguishment
Feb 18, 2026



Methods of Fire Extinguishment

Fire remains one of the most serious hazards on board ships and offshore installations. Effective firefighting depends on understanding the fire tetrahedron heat, fuel, oxygen, and the chemical chain reaction. By removing or interrupting any of these elements, a fire can be controlled and extinguished. Below are the four primary methods of fire extinguishment used in maritime operations.

1. Cooling

Cooling reduces the temperature of the burning material below its ignition point. Water is the most commonly used cooling agent because of its high heat-absorbing capacity. When applied properly, water removes heat from the fire and surrounding surfaces, preventing re-ignition. Foam may also provide a cooling effect while offering additional smothering benefits. Cooling is particularly effective for Class A fires involving solid combustibles such as wood, paper, and textiles.

2. Smothering

Smothering works by cutting off the oxygen supply required to sustain combustion. This can be achieved using foam, CO₂, fire blankets, or fixed fire suppression systems. By creating a barrier between the fire and the surrounding air, smothering suppresses flame spread and prevents further combustion. This method is commonly used for liquid fires and enclosed space incidents on board vessels.

3. Starvation

Starvation involves removing or isolating the fuel source feeding the fire. On ships, this may include shutting off fuel valves, isolating electrical supplies, or removing combustible materials from the affected area. By eliminating the fuel component, the fire cannot continue to burn. Quick identification and isolation of the fuel source are critical to successfully applying this method.

4. Inhibiting the Chemical Reaction

This method interrupts the chemical chain reaction occurring within the flame. Dry chemical powders and certain clean agent extinguishers are designed specifically for this purpose. They stop the combustion process at a molecular level, making them highly effective for flammable liquid, gas, and electrical fires. Rapid application ensures that the chain reaction is broken before the fire escalates.


The Importance of Proper Firefighting Knowledge

Understanding these four methods allows seafarers and offshore personnel to respond effectively during emergencies. Proper training, routine drills, and familiarity with onboard firefighting equipment are essential to ensuring safety at sea.

WILLIAMSON TURN

The Williamson Turn is a maneuver used to reverse the course of a vessel and return along its original track. It is primarily applied during Man Overboard (MOB) situations, especially when the exact position of the casualty is uncertain or when visibility is poor, such as at night or in fog. Purpose: • To bring the ship back onto its previous course line, improving the chance of relocating the person who fell overboard. • Ensures the vessel returns to the point of incident efficiently and safely. • Helps maintain visual and navigational reference in low-visibility conditions. Procedure: 1. Apply full rudder toward the side where the person fell overboard. 2. Allow the vessel to deviate 60° from its original course. 3. Shift full rudder to the opposite side. 4. Continue the turn until the vessel is heading about 20° from the reciprocal (opposite) course. 5. Return rudder to midships. 6. Steady the vessel on the reciprocal course and proceed back along the original track to search for and recover the casualty.

Mooring Equipment

Mooring Equipment plays a critical role in ensuring the safe berthing and securing of vessels in ports and terminals. Designed to handle heavy loads and dynamic forces, these fittings guide, control, and hold mooring lines in place while minimizing wear and operational risk. Double Bollards ‣Used for securing mooring lines on deck; allows multiple lines to be fastened and provides strong holding capacity during berthing. Mooring Roller ‣Guides mooring lines smoothly during heaving or paying out, reducing friction and preventing line damage. Horn Cleat ‣Simple deck fitting used to secure light mooring lines or ropes by wrapping them around its two horns. Panama Bow Curved Bulwark ‣Reinforced bow fitting designed to guide mooring lines safely over the ship’s bulwark with minimal wear. Cruciform Bollard ‣Cross-shaped bollard that allows multiple mooring lines to be secured from different directions. Smit Bracket ‣Heavy-duty fitting used for towing operations; guides towing lines and absorbs high towing loads.

PERSONAL PROTECTIVE EQUIPMENT (PPE)

Personal Protective Equipment (PPE) is the frontline defense of every seafarer working onboard. It protects crew members from physical, chemical, and environmental hazards while ensuring safe and efficient operations. Each piece of PPE serves a specific purpose that collectively reduces risk, prevents injury, and promotes a safety-first mindset onboard. 1. Protective Helmet Provides essential head protection against falling objects, impact, and accidental bumps in confined or elevated spaces. A mandatory requirement in all deck and engine operations. 2. Eye Wear (Safety Goggles) Shields the eyes from dust, debris, chemicals, sparks, and flying particles. Crucial during maintenance, grinding, chipping, or chemical handling. 3. Earmuff / Hearing Protection Reduces excessive noise levels from machinery, engines, and power tools. Helps prevent long-term hearing damage and fatigue. 4. Dust Mask (Respiratory Protection) Protects the wearer from inhaling dust, fumes, mist, and harmful airborne particles commonly encountered during painting, sweeping, or chemical tasks. 5. Safety Overalls Flame-retardant coveralls designed to protect the body from heat, sparks, oil splashes, and minor chemicals. High-visibility strips ensure the wearer remains easily seen. 6. Safety Gloves Provides hand protection against abrasions, cuts, chemical contact, and heat. Different glove types may be used depending on the task. 7. Safety Harness Critical for working aloft or in elevated areas. Prevents falls and secures the crew while working at height or over the side. 8. Safety Shoes Steel-toe or composite-toe footwear that protects the feet from heavy impacts, sharp objects, slips, and electrical hazards. Designed for tough marine environments.

Safety First: Essential Welding PPE for Maritime Professionals

Safety First: Essential Welding PPE for Maritime Professionals In the maritime industry, safety is not optional it is a responsibility. Welding operations on board vessels and in shipyards expose workers to intense heat, sparks, radiation, and heavy materials. That is why wearing complete and proper Personal Protective Equipment (PPE) is critical Complete Welding Protection from Head to Toe Welding Helmet A high-quality welding helmet protects the eyes and face from harmful UV and infrared radiation, flying sparks, and intense light. Auto-darkening features enhance visibility while ensuring maximum eye protection during arc welding. Protective Coverall Flame-resistant coveralls provide full-body protection against heat, sparks, and minor splashes of molten metal. Designed for durability and comfort, they allow welders to move freely while staying protected.
