GAS (GAS):

Explanation: This is a signal sent from the premises alerting us to the possibility of toxic or explosive gas present. (Usually carbon monoxide or natural gas) This information should come from the alarm company verified by the fire department at the time of installation.)

Response Plan: The Monitoring Center will call the premises, unless in a dispatch-immediately city or otherwise noted in account, and attempt to abort the alarm. If someone answers at the premises they will be notified of the type of alarm we are receiving and asked if they need assistance. An ID and name will be obtained, and the person will be asked if everyone at the premises is feeling all right. They will be asked if anyone is experiencing any headache, dizziness, or nausea. If they answer yes to any of these questions, then the fire department should be notified to investigate the source of the toxic gas even if proper ID is given. If premises number is busy, there is an answering machine, no answer, or no ID given, we will dispatch the fire department and notify the call list. If ID given and no adverse symptoms or signs of gas, then the person will be advised to have service check the gas detectors for malfunction.

Procedure: Hit Enter to retrieve the signal from the traffic screen and check comments and history (ALT-F3, ALT-F4, and ALT-F6) to be certain alarm is verifiable. (Some cities require dispatch immediately on all gas alarms.) Verify at premises\by picking up a phone line and hitting F2 to autodial the premises, unless comments indicate otherwise. Get name and ID of person answering, notify of type of alarm received and ask if all at the premises are all right. Ask if anyone is experiencing headache, dizziness or nausea. If anyone is experiencing these symptoms, advise them the fire department will be sent to check and they should wait outside for them to arrive. If proper ID is given and sub says everyone at premises is fine and no reason for alarm, then advise them to have service check the detector. If no answer, no ID or improper ID is given, dispatch fire department and notify the call list.

Possible Causes: Actual toxic gas leak from a gas heater, gas dryer, generator, gas grill, propane tank, etc. Dirt or dust in detector, spray- painting or construction work going on without detector covered, or possible detector malfunction.

Suggested Operator Script:

Does anyone feel dizzy, nauseous, or have a headache? Can I have your ID and your name?
