What cooling equipment must be planned for site setup during high heat?

• A. Fans, insulated coolers or water jugs, and shaded shelters
• B. Portable heaters
• C. Dehumidifiers only
• D. None

Answer: (A)

When workers face high heat, the aim is to reduce heat strain and keep everyone hydrated and able to rest comfortably. Fans help by moving air, which makes heat feel cooler and helps sweat evaporate, lowering the body’s heat buildup. Shaded shelters provide relief from direct sun and give a cooler place to take breaks. Insulated coolers or water jugs ensure a steady supply of cold drinking water, promoting hydration, which is crucial in hot conditions. Put together, these elements support safer, more comfortable work conditions in heat.

Portable heaters would worsen the problem in hot conditions, as they add warmth rather than remove it. Dehumidifiers target moisture in the air but don’t cool the environment or ensure hydration. And choosing none ignores the risk of heat illness.
