Which items are examples of personal protective equipment (PPE) associated with RWP?

Personal protective equipment (PPE) is essential for ensuring the safety of roadway workers in potentially hazardous environments. The examples given in the correct choice – hard hats, reflective vests, safety glasses, and hearing protection – are all designed to protect workers from various types of risks they may encounter on the job.

Hard hats protect the head from falling objects or potential bumps, which is crucial in construction and maintenance areas. Reflective vests increase visibility, particularly in areas with vehicle traffic, ensuring that workers are seen by operators of machinery and vehicles. Safety glasses shield the eyes from flying debris and other hazards, and hearing protection is vital in environments where noise levels may exceed safe limits, helping to prevent hearing loss.

The other options contain items that may provide some utility in certain contexts but do not all meet the standards or primary purposes of PPE defined in roadway worker protection. For instance, while helmets and knee pads (another set of choices) may offer protection, they are not as universally required as the items in the correct answer. Gloves and masks can be important for specific health and safety scenarios but do not universally match the specific risks associated with roadway work. First aid kits and water bottles, while important for overall safety and health management, are not classified as
