Spot The Safety Violation: Protecting Workers from One Hazard Shouldn’t Expose Them to Another

Do we really need to explain the safety hazards depicted in this picture’

Heat stress is a real safety hazard during the summer. For example, in the summer of 2012, there were about 82 heat-related deaths in the US and Canada. And yes, providing workers with a shady spot for breaks is one way to help protect them from getting overheated. But there isn’t any situation in which it would be proper for the equipment in this picture to be in this position’much less for workers to take refuge from the heat underneath it.

Heat-Related Illnesses

Heat stress is an umbrella term used to describe the stress or impact on the body when it’s exposed to high temperatures and/or humidity for lengths of time. There are several different types of heat-related illnesses:

  • Heat stroke: the most serious type of heat illness is a result of body heat overload;
  • Heat exhaustion, which is caused by excessive loss of water and salt;
  • Heat edema, which is a swelling of hands, feet and ankles;
  • Heat rash, a red bumpy rash with severe itching; and
  • Heat cramps, which usually occur in the most worked muscles, such as arms, legs or stomach.

The OHS laws in every jurisdiction either directly or indirectly require employers to protect workers from heat stress‘whether the source of that heat is the weather or equipment in the workplace.

Example: An Ontario bakery worker died of heat stress on the job. Inside the bakery, the temperatures topped 36o. The MOL charged the bakery with violating the general duty clause because it didn’t have a heat stress policy as required by the MOL guidelines. The bakery pleaded guilty and was fined $215,000 [Weston Bakeries Limited, Govt. News Release, Feb. 18, 2004].

10 Ways to Protect Workers from Heat Stress
