What is the maximum allowable concentration of nitrous oxide in a healthcare facility according to OSHA?

The maximum allowable concentration of nitrous oxide in a healthcare facility, as established by OSHA (Occupational Safety and Health Administration), is indeed 25 parts per million (ppm). This concentration limit is set to ensure that workers are not exposed to hazardous levels of nitrous oxide over the course of their work, as prolonged exposure can lead to health issues, including potential neurological effects. Maintaining levels at or below this threshold is essential for protecting the safety and health of both staff and patients in medical environments. This standard reflects OSHA's commitment to ensuring safe working conditions, particularly in areas where anesthetic gases like nitrous oxide are used extensively.
