Which criterion is used for selecting PPE for cold stress?

• A. Insulation, layering, and venting principles
• B. Color of fabric
• C. Only cost considerations
• D. Availability

Answer: (A)

Selecting PPE for cold stress focuses on how well the gear controls heat loss and handles moisture. The best criterion is insulation, how it can be layered, and venting capabilities. Insulation reduces heat loss from the body, which is crucial in cold environments. Layering lets workers tailor protection to different activity levels and changing conditions—adding or removing layers to stay warm without overheating. Venting or breathable fabrics are important because they let sweat escape so moisture doesn’t build up inside the clothing, which would chill the worker once they stop moving or environments cool further. This approach directly affects safety and comfort: proper insulation combined with versatile layering and moisture management minimizes the risk of hypothermia, numbness, and fatigue. In contrast, the color of the fabric doesn’t determine thermal protection, cost considerations don’t guarantee adequate protection, and availability doesn’t ensure the PPE meets the necessary thermal performance.
