Final answer:
When engineering and administrative controls are not feasible to reduce hazards, Personal Protective Equipment (PPE) must be used to ensure worker safety as mandated by OSHA.
Step-by-step explanation:
When engineering and administrative controls are not feasible or practical for reducing exposure to potential hazards in the workplace, Personal Protective Equipment (PPE) must be used. This is because employers have a responsibility under the Occupational Safety and Health Act (OSHA) to provide a safe workplace, which includes finding and correcting safety and health problems. Employers should prioritize eliminating or reducing hazards by making changes in working conditions, but when that is not possible, providing required PPE at no cost to workers is the next step. PPE can include items such as masks, gloves, safety harnesses, or earplugs to protect workers from specific hazards. If workers believe that their workplace is not safe or that their employer is not following OSHA standards, they have the right to file a complaint with OSHA.
