WARNING! Actions to be taken in case of alarm
1) Put out all free flames.
2) Close the main gas tap or the LPG cylinder tap.
3) Do not turn any lights on or off; do not turn on any electrical device or appliance.

If the alarm continues and the cause of gas presence cannot be found or removed, abandon the building
and call the emergency services when outside (fire department, distributors, etc.)

sufficient concentration to activate the general alarm.
