Residential CO detector sensitivity?

[Viper GTS]

Anybody happen to know at what level typical residential CO detectors sound an alarm?

It doesn't list the sensitivity in the manual somewhere?

i think around 25-35 ppm

OSHAs limit is 50ppm for 8 hours, and I think 200 ppm is considered dangerous.

So probably something a little under 50 ppm.

That's what I would have figured.

Basically there are two residential CO detectors that have been going off in part of our office. The powers that be have removed the batteries, claiming that the only problem is they're not designed for use in a warehouse environment.

Problem is they aren't in the warehouse, they're in office space. And they're all of 3' off the ground.

My logic says if they're going off there's a problem, even if it is localized to that area.

Nevermind that outside people coming in are commenting that they smell gas.

I have always found the best way to fix a problem is to remove whatever is detecting said problem. 😛

I would call the police immediately, that is simply unacceptable.

Yeah that is pretty ridiculous, call 911 or local fire department I'm sure they have detectors that can count ppm.

Get a detector with a readout of PPM.
Or tell the boss
"I'm getting sleepy...."

The CO detectors that I've put in our farm houses all go into a 'chirp' alarm at 36 PPM, I believe. They go into full alarm at like 45-50 PPM, IIRC.

And whether or not they're suitable for use in a warehouse (propane forklifts, tractors, etc.) if they're going off that means they're detecting that level where they are...

Correct?

I believe you can buy commercial version that are programmable.

Correct - no alarm will sound, regardless of where they are suitable for use, unless they are detecting a problem (of whatever setpoint they are configured to alarm).

There are many, many false alarms at this time of year because of numerous reasons (and I've honestly not looked into all of them, though having a faulty detector and/or weak batteries is typically the #1 culprit). If anyone is saying that they smell gas, or if anyone is feeling sleepy, then the fire department needs to be notified, and/or an evacuation performed if the situation gets too bad.

The ppm level may not be *that* high, but it's *ALWAYS* better to be safe than sorry, with CO. I've had neighbors die because their alarms failed.

Call OSHA, too. BIG fine, possible loss of jobbage.
