how much is deadly in a 10 by 10 room
Copilot
Carbon monoxide (CO) levels can be extremely dangerous in enclosed spaces1. Here are some key points to consider:
9 ppm (parts per million) is the maximum safe level for indoor exposure over 8 hours1.
 
200 ppm or greater can cause physical symptoms and is fatal within hours1.
800 ppm or greater is fatal within minutes1.
 
In a 10 by 10 room, even a small amount of CO can quickly reach dangerous levels, especially if the room is not well-ventilated. It's crucial to get fresh air immediately and seek medical attention if you suspect CO exposure. #CARBONMONOXIDE
