I'm the CEO and cofounder of Glowforge - we're so saddened by this tragedy. Our product was not involved, but that doesn't make us feel any better about this loss.

If you use a laser, ours or anyone else's, please go back right now and re-read the safety instructions. Accidents like this should never happen. My heart breaks for those affected by this.

OK, it's good to know it wasn't yours. Thanks.

It would be appropriate to put a CO detector in your units before somebody does that with one of yours. That definitely needs to be in the "filtered" units that are supposed to operate with no ventilation.

Might be worth editing your original comment to remove the suggestion that it's a Glowforge, just to avoid unnecessarily associating a specific company that wasn't involved in this tragedy.

Are there CO detectors to buy to react before it's too late ?

[justincormack]

Many smoke alarms also measure CO now.

Even if there were smokealarms with CO dedection it's really bad practice. Carbon monoxide dedectors need to be installed on to walls 100-150cm from the floor. In the bedroom I would recommend the height of bed. The reason for all that is the fact that CO molar mass is really similar to air molar mass AKA "that shit will reach the sealing when you're long dead".

Sorry, but what are you talking about?

Yes, CO is similar to air's molar mass (it's actually slightly lower), meaning it will diffuse evenly through the vertical space in the room. The concentrations at the ceiling will be the same as the concentrations on the floor.

Stop spreading misinformation.

[agumonkey]

But if sources are at human head level, by the time it reaches the ceiling, you already inhaled a fair amount of CO ? what did I get wrong ?

[pixelbill]

Nope.

Diffusion of gasses in the air is an extremely rapid process. In a minute the concentration would be the same throughout the room.
