What is the IDLH level of carbon monoxide according to OSHA?

The IDLH, or Immediately Dangerous to Life or Health, level of carbon monoxide according to OSHA is set at 1,000 ppm (parts per million). This designation indicates that exposure to this concentration presents an immediate risk of severe health effects or death.

In occupational safety, the IDLH level is crucial for determining safe working conditions, especially in environments where carbon monoxide might accumulate, such as in confined spaces or during firefighting operations. The threshold of 1,000 ppm was established because at this concentration, even short-term exposure can pose serious health risks, such as loss of consciousness, nervous system effects, and potentially fatal outcomes. Understanding these limits is vital for emergency responders and safety professionals to ensure that they take appropriate precautions and use necessary personal protective equipment when dealing with carbon monoxide.
