1200 ppm
A level of carbon monoxide (CO) greater than 70 parts per million (ppm) is considered dangerous and can lead to symptoms like headaches, dizziness, and nausea. Levels exceeding 150 ppm can be life-threatening and require immediate evacuation and medical attention. It is crucial to have a working CO detector in your home to monitor levels and ensure safety.
800 ppm
The acceptable levels of carbon monoxide in a normal home are typically below 9 parts per million (ppm) in the air over an 8-hour period or below 35 ppm over a 1-hour period. It is important to have a working carbon monoxide detector to monitor levels and ensure safety.
Yes, dogs are susceptible to carbon monoxide poisoning. Inhaling high levels of carbon monoxide can be lethal for dogs, as it prevents oxygen from reaching their organs and tissues. It's important to ensure that your living space is properly ventilated and that carbon monoxide detectors are installed to protect both you and your pets.
The European safe limit for carbon monoxide exposure is typically set at 10 parts per million (ppm) averaged over an 8-hour period according to the European Union Ambient Air Quality Directive. Short-term exposure should not exceed 30 ppm averaged over a 15-minute period.
Practically instant unconsciousness followed by a quick death.
The First Alert Plug-In With Battery Backup Carbon Monoxide Detector has all the features you are looking for.
A good level for a carbon monoxide detector is one that meets the UL (Underwriters Laboratories) safety standards, which typically range from 30 to 70 parts per million (ppm) for a residential setting. It is important to check the specific guidelines provided by the manufacturer of the detector to ensure it is set at a safe level to effectively detect and alert you to any potential carbon monoxide hazards.
Carbon Dioxide according to Walter Adams and Theardore Dunham.
Carbon dioxide (CO2) makes up about 0.04% of the Earth's atmosphere by volume. This translates to approximately 400 parts per million (ppm). While this percentage is small, it plays a crucial role in regulating the Earth's climate and supporting life through the greenhouse effect. Other forms of carbon, such as carbon monoxide and methane, are present in even smaller amounts.
Active on-duty firefighters are likely to experience adverse health effects from inhaling 300 ppm of carbon monoxide faster than off-duty firefighters due to their increased physical exertion and stress levels while fighting fires. This heightened activity raises their heart rate and respiratory rate, leading to faster absorption of carbon monoxide into the bloodstream. Additionally, on-duty firefighters may be exposed to other hazardous substances and conditions that can exacerbate the effects of carbon monoxide exposure, making them more vulnerable to its toxic effects.
It depends how much traffic is about. Carbon monoxide is not a naturally-occurring molecule, & is only produced by engines; once it gets into the atmosphere, the carbon satisfies its valency by pairing up with any stray atoms it can find, preferably oxygen.
