If you smell gas or suspect carbon monoxide
If you smell gas, turn off the supply if it's safe to do so, get everyone out, ventilate the boat and have the system checked by a competent engineer.
A carbon monoxide alarm will not detect a gas leak so both risks need to be taken seriously. If a carbon monoxide alarm sounds or anyone feels unwell with symptoms such as headache, dizziness or nausea, move into fresh air immediately and seek urgent medical advice.
Gas Safety on Boats (Gas Safe Register)
In an emergency
If there is a fire, get everybody off the boat if you can do so safely, stay out, and call 999. Do not re-enter the boat. If the boat is moored, help people move away from smoke and flames and warn nearby boaters if there is immediate danger.
Check your smoke and carbon monoxide alarms today and test them regularly. Arrange servicing and safety checks for gas, heating and fuel-burning appliances by a competent boat-qualified engineer. Review escape arrangements and make sure everyone on board knows what to do in an emergency. Use the trusted external resources below for more detailed guidance.
