Risk Factors for Heat-Related Illness

Workplace Factors

Certain workplace conditions and practices can increase the risk of heat-related illnesses.

These include:

  • Outdoor Work: Jobs that require working outside, such as construction or landscaping, expose workers to high temperatures and direct sunlight.
  • Hot Indoor Workplaces: Environments like kitchens, factories, and foundries can have high ambient temperatures due to heat-producing equipment.
  • Protective Clothing: Wearing heavy or non-breathable protective gear can trap heat and restrict the body’s ability to cool down.
  • Physical Exertion: Jobs that involve intense physical activity raise body temperature and increase the risk of heat stress.
  • Insufficient Breaks: A lack of adequate rest breaks in a cool environment can prevent the body from cooling down properly.

To mitigate these risks, employers and workers should consider measures like scheduling work during cooler parts of the day, using ventilation or cooling systems, providing hydration, and allowing regular breaks in shaded or cooler areas.
