Final answer:
Steam and compressor plants shall conform to the requirements of the Occupational Safety and Health Act (OSHA), which grants OSHA the authority to issue workplace health and safety regulations.
Step-by-step explanation:
The Occupational Safety and Health Act's (OSHA) regulations must be followed by steam and compressor plants. The OSHA Act gives OSHA the power to impose rules pertaining to workplace health and safety, such as making sure employees operating hazardous machinery are safe, shielding them from dangerous chemicals, requiring training for certain dangerous jobs, and providing personal protective equipment. The OSHA Act's General Duty Clause, which mandates that employers maintain their workplaces free of major recognized hazards, must also be followed by employers.
