Final answer:
OSHA is responsible for classifying soil and setting standards for employers to protect their workers from hazards.
Step-by-step explanation:
The Occupational Safety and Health Administration (OSHA) is responsible for classifying soil. OSHA sets and enforces standards that employers must follow to protect their workers from hazards.
These standards include requirements for employers to provide fall protection, prevent exposure to hazardous chemicals, and ensure the safety of workers in confined spaces.
Employers are also required to comply with the General Duty Clause of the OSH Act, which mandates keeping workplaces free from recognized hazards.
