We know all know this summer is hot, but what does it mean for workers? In These Times published an article by Elizabeth Grosman in July, “As Temperatures Climb Across the Country, Workers Will Suffer”. Her article examines the situation in the U.S., reporting that in 2015, “the federal Occupational Safety and Health Administration (OSHA) received more than 200 reports of workers hospitalized because of heat-related illness and at least eight deaths associated with heat exposure. In 2014, 2,630 U.S. workers suffered from heat illness and 18 died on the job from heat stroke and related causes. Since 2003, an average of more than 30 workers a year have died of heat-related causes. The article also point out that 9 of the 30 deaths occurred to workers who had been on the job less than 3 days – making this an issue which might be improved by training and stronger OHS contract language. In 2014, OSHA launched a “Heat Rest Shade” campaign to remind employers of their obligation to provide respite for workers , and with online training materials and information resources .
The Ontario Ministry of Labour updated their guidance re Heat Stress in 2014, and the Heat Stress Awareness Guide published by the Occupational Health and Safety Council of Ontario in 2007 is still valuable. It too points out the risks to new employees and those who are not conditioned to heat. For Canada-wide information, see the Canadian Centre for Occupational Health and Safety Fact Sheets here or see (from 2010) Protecting Workers from Heat Stress: What are an Employer’s Legal Obligations?
Being unemployed is also a factor in heat-releated illness according to an article in Environmental Health Perspectives . Researchers led by Hung Chak Ho of Simon Fraser University in B.C. developed a block-by-block map of neighbourhoods in Vancouver and discovered that those blocks with a high proportion of low-income earners, a high proportion of renters and a high unemployment rate are at greater risk of mortality than the elderly. See “Unemployed people, not the elderly, at highest risk” for a summary.
And amidst the high heat and drought that all of us are feeling in central Canada this summer comes scientific validation of our experience: the release of State of the Climate 2015 , the 26th edition of the assessment released each summer as a supplement to the Bulletin of the American Meteorological Society. Canada is profiled in Chapter 7 : “The annual average temperature in 2015 for Canada was 1.3°C above the 1961–90 average, and was the 11th warmest year since nationwide records began in 1948.” (The warmest year on record for Canada to date has been 2010, at 3.0°C above average.) Globally, the report catalogues several symbolic mileposts: notably, it was 1.0°C warmer than preindustrial times, and the Mauna Loa observatory recorded its first annual mean carbon dioxide concentration greater than 400 ppm in 2015. A thorough summary appeared in The Guardian (August 2). ( State of the Climate is compiled by the U.S. National Oceanic and Atmospheric Administration’s Center for Weather and Climate, from contributions from scientists from 62 countries, and is the recognized authority on global climate indicators and notable weather events).
