Question: 1 / 400

According to OSHA, what is the Permissible Exposure Limit (PEL) for Ammonia?

5 PPM

50 PPM

The Permissible Exposure Limit (PEL) for ammonia as specified by OSHA is set at 50 parts per million (PPM) as an 8-hour time-weighted average. This limit is established to protect workers from the harmful effects of ammonia exposure, which can include respiratory issues, irritation to the eyes and skin, and other health concerns related to both acute and chronic exposure.

Setting a PEL is crucial for maintaining safe working environments, as it helps to mitigate the risk of toxic exposure while allowing for some level of environmental exposure that is considered safe under normal operating conditions. The value of 50 PPM reflects an extensive review of scientific data regarding ammonia's toxicity and establishes a guideline that employers must adhere to for the safety of their employees.
