Warmer temperatures have brought the Black-legged tick  to Ontario, bringing an increase of Lyme’s Disease, especially for outdoor workers.

A  Guidance Document was released by the  American College of Occupational and Environmental Medicine in February 2018.  Responsibilities of the Occupational and Environmental Medicine Provider in the Treatment and Prevention of Climate Change-Related Health Problems  (also appearing  in the Journal of Occupational and Environmental Medicine ) is intended to set standards for physicians specializing in workplace health.  The Guidance Document  provides concise and very current information about  the direct physical impacts related to climate change (heat stress and ultraviolet exposure, air quality, and allergic sensitivities) as well as indirect impacts (disaster zone exposure, stress and mental health, and waterborne and vector-borne disease).  Most of this information is not new:  two previous major reports have covered the same ground: The Lancet Countdown Report for 2017,  (which links climate change and specific health conditions for the population at large, not just workers, and which included a report for Canada ), and the landmark U.S . Global Change Research Program report, The Impacts of Climate Change on Human Health in the United States: A Scientific Assessment (2016)  .

What is important about this new Guidance Document?  It focuses on the workplace, and sets standards for the role of occupational health physicians which include a responsibility to protect workers.  For example:  “Provide guidance to the employers on how to protect working populations in the outdoors or in the field who are potentially exposed to the extreme temperatures…. Quickly identify employees with acute and chronic cardiovascular and respiratory illnesses within the organization who will be significantly affected by increasing temperature and worsening air quality, an increase in ozone, particulate matter, and high pollen count  ….Provide effective guidance to employers about seasonal activity and address the increasing risk of vector-borne disease among the working population…. Deliver support to the employees at risk for mental illness due to disasters, loss, and migration by providing more comprehensive programs through their employment….  The article concludes with: “ OEM providers are called to be on the forefront of emerging health issues pertaining to working populations including climate change. The competent OEM provider should address individual and organizational factors that impact the health and productivity of workers as well as create policies that ensure a healthy workforce.”

There is also a call to action in a new report from France’s Agency for Food, Environmental and Occupational Health & Safety.  The full expert analysis is available only in French ; an English abstract is here .  The report  predicts the occupational risks associated with climate change, from now till  2050, and identifies the main drivers of change: rising temperatures, changes in  the biological and chemical environment, and a change in the frequency and intensity of extreme events.  What’s new in this report?  It highlights the breadth of impact of climate change, stating that it will affect all occupational risks, except those associated with noise and artificial radiation.  The report also makes recommendations,  urging immediate workplace awareness campaigns and training about the health effects of climate change, with a preventive focus. From the English summary: “The Agency especially recommends encouraging all the parties concerned to immediately start integrating the climate change impacts that are already perceptible, or that can be anticipated, in their occupational risk assessment approaches, in order to deploy suitable preventive measures.”  The full report (in French only):  Évaluation des risques induits par le changement climatique sur la santé des travailleurs  (262 pages) is dated January 2018 but released in April. It was requested by France’s Directorate General for Health and the Directorate General for Labour, to support the country’s 2011 National Adaptation to Climate Change Action Plan (PNACC).
