Know the fire classes
Class A is solids such as wood and fabric, class B is flammable liquids such as fuel and oil, and class C is gases. Multi-purpose dry powder extinguishers cover A, B and C and suit most small boats. The rating on the label, such as 13A 89B C, shows how large a fire it is tested to put out.
Where to mount them
Mount extinguishers where you can reach them without passing the fire: near the helm, near the engine space and in the cabin. Use the supplied bracket so they stay put in a seaway.
Fire blankets
A fire blanket smothers small fires in a galley pan or on clothing without the mess of powder. Keep it beside the cooker.
Monthly checks
Check the pressure gauge is in the green, the safety pin and seal are intact and the body has no corrosion or dents. Replace or service extinguishers after use or when the gauge drops.
Rules and approvals
Marine Equipment Directive (MED) approval means the extinguisher is tested for use at sea. Check how many extinguishers and what size your maritime authority requires for your boat's length.
