Gas Detection

7.1

Suitable means for detecting the leakage of gas should be provided in any compartment containing a gas-consuming appliance, or in any adjoining space of a compartment into which the gas (more dense than air) may seep.

7.2

Gas detectors should be securely fixed in the lower part of the compartment in the vicinity of the gas-consuming appliance and in other space(s) into which gas may seep.

7.3

Any gas detector should, preferably, be of a type that will be actuated promptly, and automatically by the presence of a gas concentration in air of not greater than 0.5% (representing approximately 25% of the lower explosive limit) and should incorporate an audible and a visible alarm.

7.4

Where electrical detection equipment is fitted, it should be certified as being flameproof or intrinsically safe for the gas being used.

7.5

In all cases, the arrangements should be such that the detection system can be tested frequently while the yacht is in service.
