What is the IDLH (Immediately Dangerous to Life or Health) level for ammonia according to OSHA?

The IDLH level for ammonia is set at 300 parts per million (ppm) according to OSHA (Occupational Safety and Health Administration) guidelines. This value reflects the concentration at which exposure is considered immediately dangerous to life or health.

The IDLH determines the maximum concentration of a hazardous substance in the air that is likely to pose a risk of death or permanent health impacts. For ammonia, concentrations at or above this level can lead to severe health effects, including irritation of the respiratory tract, choking, or even more severe respiratory distress, which is why it is crucial to monitor and mitigate exposure at this concentration.

Understanding the IDLH level is essential for ensuring proper safety protocols are in place in environments where ammonia is present, protecting workers from potentially life-threatening situations.
