Which protective measure is essential for embalmers according to OSHA regulations?

The essential protective measure for embalmers according to OSHA regulations is adopting work practice controls. This approach focuses on the implementation of safe practices and procedures to minimize exposure to hazardous materials during embalming. Work practice controls can include using tools and techniques that reduce contact with blood or body fluids, thereby ensuring a safer work environment.

By following established work practices, embalmers can effectively safeguard their health while performing their duties, which is crucial given the potential exposure to pathogens and chemicals in this line of work. This aligns with OSHA's overarching goal of ensuring workplace safety through comprehensive risk management and prevention strategies.

Wearing masks and changing clothing might be important in certain contexts but do not encompass the broader framework of operational safety that work practice controls provide. Relying solely on hand sanitizer does not address all possible modes of exposure and should be part of a more holistic approach to safety, rather than a standalone solution.
