Marine Gas Detection

Suitable means for detecting the leakage of gas should preferably be provided in each compartment containing a gas-consuming appliance. Gas sensor heads should be protected against damage cause by water and other corrosive agents, and the risk of mechanical damage.

The consequences of a LP gas leak on board a boat can be disastrous. Every year there are deaths and injuries on board boats, which could have been avoided with the installation of easy to use and cost effective gas detection equipment.

LP Gas is not regarded as poisonous but is explosive and can lead to devastating explosions if it builds up to sufficient levels. It is measured using what's called the Lower Explosive Limit (LEL). This means that when the concentration of gas reaches 100% LEL it becomes explosively dangerous (i.e. if you lit a match it would go bang). Most gas alarms are calibrated to alarm at 10% LEL, well before the gas becomes explosively dangerous.

A strong smell of gas can be noticed when the concentration is only 0.5% to 1% LEL because gas suppliers add a harmless but strong smelling chemical to the gas. Despite the strong smell this level is not dangerous and therefore the alarm will not sound. This reduces the possibility of false alarms. If your alarm sounds follow the action plan list on our emergency action notice.
