Protective clothing should be utilized when exposure to a hazard could cause impairment through which of the following?

Protective clothing is essential in situations where there is a risk of harm due to various exposure pathways, such as absorption, physical contact, or inhalation. Hazards can manifest in many forms, including chemicals, biological agents, or particulate matter, each presenting different risks of exposure.

When considering absorption, harmful substances can penetrate the skin and enter the bloodstream, leading to systemic effects. Physical contact can result in direct skin injuries or irritation from hazardous materials. Inhalation involves breathing in harmful particles or vapors, which can affect the respiratory system and overall health.

Utilizing protective clothing serves as a barrier, mitigating the risks associated with these multiple exposure routes. Therefore, when any of these pathways pose a potential hazard, protective clothing is warranted to ensure safety. This comprehensive approach acknowledges that hazards can affect individuals through various means simultaneously. Thus, the answer that encompasses all these possibilities is the most appropriate choice.
