The OSHA Respiratory Protection Standard (“the Standard”; 29 CFR 1910.134) uses 19.5 percent oxygen as the level below which an oxygen-deficient atmosphere exists and requires, generally, that all oxygen-deficient atmospheres be considered immediately dangerous to life or health (“oxygen-deficient IDLH”).
Is 19.5 oxygen safe?
Oxygen Atmospheres Based on OSHA guidelines, a confined space is considered to have safe oxygen levels if readings are between 20.8-21 percent, while a space with readings of less than 19.5 percent are considered to be oxygen deficient.
What is a good oxygen level?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
