I am seeking guidance on what type of carbon monoxide detector would be appropriate for a public works garage. Would an alarm installation company need to be consulted or are there "off the shelf" detectors that could be used? Thank you!
What are you trying to accomplish with these??
What is going on in the garage???
Working on vehicles??
working on equipment??
Is there a fire alarm system installed in the building/garage already???
Thank you for your follow up questions. CO detection is to alert employees in the garage or perhaps adjacent office of high level of CO present due to vehicles and/or other equipment (heating equipment, for example) usage/malfunction. Vehicles are being warmed up, moved in and out of garage; equipment is being repaired. Some garages have a fire detection system, some don't. Some with systems are able to get CO detection from alarm companies. Others say alarm company can't help with CO.
I will say that if you have CO detection devices of the off the shelf variety, they will be set off constantly on a equipment bay floor unless all vehicles are connected to an exhaust extraction system. Especially if any vehicles are gasoline powered. We used to set off our CO monitors in the apparatus just by starting a pick-up of chief's buggy (before extraction system). We did install them in the quarters are of the station and found that without extraction we commonly set off the detectors closest to the bay floor doors. Of course most off the shelf units are set to alarm in the 25-35 ppm range which OSHA still considers OK for an 8 hr work day, so...
