Final answer:
OSHA protects employees and patients from physical harm and hazardous substances by setting and enforcing regulations for safe working conditions, hazard communication, and worker training.
Step-by-step explanation:
The Occupational Safety and Health Administration (OSHA) issues and enforces regulations that protect employees and patients from physical harm and hazardous substances. This includes enforcing standards and regulations that require employers to provide safe workplaces free from recognized hazards, ensure the safety of workers who enter confined spaces, prevent exposure to harmful chemicals, and provide necessary training and equipment to handle such risks. Employers are also required by law to inform workers about chemical hazards and not retaliate against workers for using their rights under the law.
