What is the maximum allowed concentration for formaldehyde exposure during embalming procedures?

• A. 0.5 ppm
• B. 2.0 ppm
• C. 1.0 ppm
• D. 0.75 ppm

Answer: (C)

The maximum allowable concentration for formaldehyde exposure during embalming procedures is established to protect the health and safety of embalmers and other workers in the funeral industry. The Occupational Safety and Health Administration (OSHA) sets the permissible exposure limit (PEL) for formaldehyde at 0.75 parts per million (ppm) for an 8-hour workday. In certain contexts, including specific embalming conditions, temporary exposures may peak at higher levels, which is why some regulatory frameworks specify a limit of 1.0 ppm as a guideline for peak exposures.

This level reflects a balance between effective embalming practices and minimizing health risks associated with formaldehyde, which can be harmful when inhaled in larger quantities over time. Understanding this standard is critical for maintaining safe work environments in mortuary science, contributing not only to the safety of embalmers but also to overall public health.
