Final answer:
Supervisors ensure safety by regularly checking and providing guidance on the proper use of hazard controls, aligning with OSHA's enforcement efforts. Regular inspections, safety training, and the use of checklists are key methods to maintain workplace safety and compliance with health standards.
Step-by-step explanation:
Supervisors ensure that employees are using the established hazard controls to perform work safely through option c: Through regular checks and guidance. This enforcement approach aligns with the Occupational Safety and Health Administration's (OSHA) efforts to reduce workplace injuries, illnesses, and fatalities by maintaining inspections without advance notice, addressing violations, and ensuring employers provide safe workplaces.
Employers must comply with OSHA standards which may include requirements like providing fall protection, preventing trenching cave-ins, and preventing exposure to harmful chemicals. To effectively enforce these regulations, supervisors conduct regular safety inspections and monitor adherence to safety practices. Furthermore, they offer safety training in a language workers understand, keep accurate records of work-related injuries, and use methods such as checklists—like those used in aviation and healthcare—to reduce accident risks.
Adherence to these procedures and the use of safety checklists, such as the WHO surgical checklist, aid in making the work environment safer by systematically confirming that all necessary precautions are in place before a task is undertaken.
