"Alarm Pattern (L-LL)"
<Response to Gas Alarm>
When a gas alarm is triggered, take actions in accordance with your company’s safety practices for a gas
alarm. In general, take the following actions.
1. Check the reading of the detector.
NOTE
If a gas leak is momentary or if the alarm is triggered by noise, the reading may already have dropped by
the time you get to the instrument to check it.
2. Based on your company’s safety practices, no one can be allowed to access the monitored zone to ensure
safety.
3. If the detector display is still indicating the presence of gas, close the area’s main gas valve, and then verify
that the detector’s gas concentration reading dropped.
4. While wearing protective equipment in case gas is still present, use a portable gas detector to ensure the
area is free from gas.
5. If you can determine that the leak point is free from dangers, take actions to fix the gas leak.
