Blog Post #337 – Manitoba WCB Warns Against Poor Heat Preparedness

Excerpt from the OH&S Canada magazine

When a heat wave hit the prairies a few years ago, an official with the Manitoba Workers Compensation Board said employers should have had a plan in place to protect people on the job.

Warren Preece of the WCB said hot weather is as much a hazard in the workplace as an unguarded saw or working on a roof without fall protection. “High heat can cause exhaustion, dizziness and even seizures in some instances.

At one Winnipeg roofing company, Randy Van Elslander said their strategy is to start early in the day and finish by noon or 1 p.m.

Another strategy some companies are using is to do split shifts, with employees working in the morning and in the evening to avoid the hottest daytime hours.

Officials also advised that if anyone spotted a co-worker appearing to suffer from heat stress to move them to a cool, shaded area, loosen or remove heavy clothing, provide cool drinking water and call 911 immediately.

My opinion

I was wondering what took so long for the recognition of Heat Stress, Heat Stroke and Heat Cramps as very real examples of a physical hazard? Steps have to be taken to protect the workers. Does anyone remember what happened at the Weston Bakery up in Barrie Ontario? Canadian employers have been fined for not protecting employees against heat-related injuries. For example, the Weston bakery was fined $215,000 after an employee died of heat stroke. The temperature in the bakery was 36 degrees Celsius, and the outside temperature 34. The bakery had a heat stress plan but hadn’t implemented at the time of the accident [Weston Bakeries Limited, Ont. MOL News Release, Feb. 18, 2004].

Some provinces, including British Columbia and Saskatchewan, have OHS regulations requiring specific measures to guard employees against extreme heat. All provinces also have a ‘General Duty’ clause similar to the one in the OSHA law.

Please consider your employees and review your company’s policy for heat stress. It will be a variation to your regular procedures but the weather changes dictate other arrangements need to be made. An employer would NEVER consider to not protect an employee during cold weather work so why would consideration not be made for employees working in hot weather?
