List hazards that require the use of PPE.

The correct choice centers around the broader category of hazards known as "processes or environment." This encompasses a wide range of potential hazards present in various job sites or environments where operational tasks are conducted, making it crucial for workers to wear appropriate personal protective equipment (PPE).

Processes or environmental hazards can include elements like working in confined spaces, exposure to adverse weather conditions, or interacting with machinery and equipment. These situations require protective measures to ensure worker safety and health, thus necessitating the use of PPE tailored to the specific conditions faced.

While chemical, radiological, and mechanical hazards are indeed specific hazards that also require PPE, they fall under the wider umbrella of environmental hazards. The concept of processes or environment is more comprehensive and represents the necessity of PPE in various operational contexts beyond just the specifics of chemical, radiological, and mechanical risks. This is important in understanding that safety measures must be adapted to the overall environment and processes at work, prompting appropriate PPE usage for comprehensive protection.
