Which of the following is NOT a factor typically used to determine PPE for a chemical hazard?

• A. Color of the worker's uniform
• B. Chemical properties
• C. Exposure route
• D. Duration of exposure

Answer: (A)

PPE selection for a chemical hazard is driven by the hazard and how workers could be exposed. The chemical’s properties—toxicity, corrosivity, flammability, volatility, and reactivity—tell you what kind of barrier is needed, such as the appropriate glove material, eye and skin protection, and whether respiratory protection is required. How exposure could occur matters too: if inhalation is possible, a respirator is needed; if skin contact is possible, protective clothing and gloves are essential; if ingestion risk exists, controls around handling and hygiene are considered. The duration and intensity of exposure also influence PPE choices because higher or longer exposure might require stronger or more durable protection and may interact with ventilation or engineering controls. The color of a worker’s uniform does not convey any information about chemical hazards or exposure risk, so it does not influence PPE decisions. The other factors are fundamental to protecting workers, whereas uniform color has no bearing on hazard assessment or protection needs.
