What is the permissible exposure limit (PEL) for an 8 hour period?

• A. .50 PPM
• B. .75 PPM
• C. 1.0 PPM
• D. 1.5 PPM

Answer: (B)

The permissible exposure limit (PEL) for an 8-hour work period is set to ensure that workers are not exposed to harmful levels of substances over a standard working day. The correct answer indicates that 0.75 parts per million (PPM) is considered a safe concentration level for certain hazardous substances, allowing for minimal risk of adverse health effects during regular occupational exposure.

This limit is based on extensive research and guidelines provided by organizations such as the Occupational Safety and Health Administration (OSHA), which establish these parameters to protect workers from the cumulative effects of exposure. Maintaining exposure below the PEL helps minimize the risk of long-term health complications, ensuring a safer environment for those engaged in activities like embalming, where exposure to chemicals is a significant concern.

The other choices represent levels that may exceed established safety guidelines for specific substances, potentially increasing the risk for negative health consequences. Thus, adhering to the PEL of 0.75 PPM is crucial for protecting the health and safety of workers in a mortuary setting.
