4 Fire prevention
4.1 Cooking and heating appliances
4.1.1 General
Cooking and heating appliances shall be suitable for use in a marine environment. When selecting appliances consideration should be given to the size and design of the space into which the appliance is to be installed and the appliance’s stated heat output.
Cooking and heating appliances shall be installed in accordance with the manufacturer’s instructions for small craft installations and secured against accidental or unintended movement. Gimballed appliances shall include a retaining mechanism that meets this requirement.
4.1.2 Appliances with flues
Where flues and associated flue pipes are installed they shall be:
— installed in accordance to manufacturer’s instructions;
— routed directly to the open air so that no exhaust gases can enter the interior of the craft;
— insulated or shielded in accordance with 4.2.3.1, where necessary to avoid overheating or damage
to adjacent material or to the structure of the craft.
4.1.3 Permanently installed fuel systems
Permanently installed (non-integral) tanks and supply lines using fuel which is liquid at atmospheric pressure shall meet the applicable requirements of ISO 21487, Iso 14895 and Iso 10088 respectively. In addition:
— permanently installed fuel tanks shall be installed outside Zone II according to Figure 1
— filler openings for tanks shall be prominently identified to indicate the type of fuel to be used with the system;
— unless covered by the design and installation requirements of ISO 14895, a readily accessible shut-off valve shall be installed in the supply line at the tank connection. If this is outside the space containing the appliance a second valve shall be fitted in the fuel line in the space containing the appliance, outside Zone II according to Figure 1, but not behind the appliance. This requirement does not apply where the tank is located lower than the cooking appliance/heater and there is no possibility of back siphoning or where a fire or fusible valve that prevents fuel from continuing to flow to an appliance in the event of a fire is installed in the appliance or near to the final fuel supply joint to it.
4.2 Materials near cooking or heating appliances
4.2.1 General
4.2.2 to 4.2.4 address the potential for the ignition of materials adjacent to cooking and heating appliances.
Materials and finishes used in the vicinity of open flame devices within the ranges as defined in Figure 1 shall comply with 4.2.2. taking into account the movement of the burner up to a heel angle of 200 for monohull sailboats or 100 for multihulls and monohull motorboats, where gimballed stoves are fitted.
These requirements do not apply to the materials of the appliance itself.
4.2.2 Protection from open flames
4.2.2.1 Free hanging curtains or other fabrics adjacent to open flame devices shall not be fitted in Zone I and Zone II according to Figure 1.
4.2.2.2 Exposed materials adjacent to open flame devices installed in Zone I and Zone II shall not support combustion and accordingly shall have an oxygen index (01) of at least 21 according to ISO 4589- 3 at an ambient temperature of 60°C, or be tested as meeting an equivalent standard. They shall be thermally insulated from the supporting structure to prevent combustion of the supporting structure, if the surface temperature exceeds 80°C during the fire test described in Annex A.
Thermal insulation may be achieved by an air gap or the use of a suitable material.
4.2.3 Protection from radiated heat devices
4.2.3.1 If their surface temperature can exceed 85°C, combustible materials adjacent to radiated heat devices and other appliances, whether exposed or covered, shall be thermally insulated to ensure that the surface temperature of the combustible materials does not exceed 85°C with the appliance operating at its maximum nominal output.ISO 9094 pdf download.
