Which acronym would a safety manager most frequently refer to concerning health hazards?

The acronym OSHA stands for the Occupational Safety and Health Administration, which is a key organization in the United States responsible for ensuring safe and healthy working conditions. A safety manager would refer to OSHA most frequently when dealing with health hazards in the workplace because OSHA sets and enforces standards to prevent work-related injuries and illnesses. The regulations and guidelines established by OSHA provide critical information on health hazards, helping organizations to comply with legal safety requirements and promote a safe working environment.

The other acronyms, while relevant in various contexts, do not focus specifically on health hazards in the workplace. KPI refers to Key Performance Indicators, which are metrics used to evaluate success in achieving goals. MASC and MRL are not widely recognized acronyms in the context of workplace safety and health, further emphasizing that OSHA is the most pertinent reference for a safety manager.
