In Case Of Alarm

Extinguish any naked flames.
Do not switch lights or electrical devices on or off.
Open all windows and doors to increase ventilation.
If the audible alarm changes from continuous to
intermittent the levels of gas have dropped. A
responsible, qualified person is now safe to find the
cause of the alarm.

If the alarm sound remains constant, and the cause
is not evident or possible to eliminate turn off the
emergency isolation valves to the area and contact
your gas provider emergency line. They will advice
accordingly.
