Heat Illness

Heat illness can affect warehousing workers performing physical work in high ambient heat, especially if the facility is also humid.

Warehousing employers should:

• Allow new or returning workers to gradually increase workloads and take more frequent breaks as they acclimatize, or build a tolerance for working in the heat.
• Provide workers with drinking water, rest breaks, and cool, shaded areas.
• Ensure the warehouse is well-ventilated.
• Train workers on heat-related illnesses, how to spot common symptoms, and what to do when a worker suspects a heat-related illness is occurring.
• Monitor workers for signs of illness and ensure access to first aid/prompt medical attention.

Hydration

It is important to drink water regular to prevent heat-related illnesses.

• Hydrate Before, During and After Work
• Drink 1 CUP (8oz) of cool water every 20 minutes, even if you aren’t thirsty.
• Water is generally sufficient for most task in the warehouse.
• If you find yourself lifting and or moving heavy objects for a long period of time
  • You may want to consider an electrolyte-containing beverage
• Avoid energy drinks, Sodas and alcohol.
