'Extreme weather and weather-related disasters that are triggered by climate change now routinely affect most states, such as wildfires in the west, hurricanes in the south, and flooding in the northeast. With longer, hotter summers, climate change has also affected the safety of those working under these more routine extreme conditions, including workers in construction, utilities, landscaping, refineries, agriculture, and emergency services and law enforcement.
The that more than 67,000 individuals visit the emergency room and more than 700 people die from heat-related health issues each year, making heat the nation’s leading weather-related killer. Meanwhile, a joint report by NPR and Columbia Journalism Investigations found that at least 384 workers in the last decade died from heat-related exposure.
According to , “between 2015 and 2019, environmental heat cases resulted in an average of 35 fatalities per year and an average of 2,700 cases with days away from work. However, the total number of heat-related fatalities may be underreported and/or improperly diagnosed. The cause of death is often listed as a heart attack when the actual cause or aggravating cause may have been exposure to a heat-related hazard. Heat-related illnesses (symptoms) range from heat cramps to heat stroke, which can potentially lead to death.”
After several states such as California, Washington, and Oregon instituted their own heat illness prevention regulations, Occupational Safety and Health Administration (OSHA) has followed suit by a notice of proposed rulemaking in October 2021 for a Federal OSHA standard for heat illness prevention for indoor and outdoor environments.
If you have employees who work outdoors or in hot conditions indoors, implementing a three-step, risk-based approach for managing heat illness at your place of work will help your organization better mitigate risks. Here we’ll cover step 1.
Step 1: Identify “at risk” workers and work activities
Managers, supervisors, and safety personnel must first develop an attunement to their employees’ working conditions by directly engaging with stakeholders. Currently, a communication gap exists between workers and managers, as they often do not experience the sweltering conditions in the same way as their employees. For example, if workers are performing strenuous labor in direct sunlight and must wear heavy clothing or PPE, even mild temperatures can make them vulnerable to heat illness.
Organizations and their employees should work together to perform heat stress risk assessments of work activities for both indoor and outdoor settings. An at-risk screening checklist, such as the HSE UK (United Kingdom’s version of OSHA) “Heat Stress Observation Checklist,” helps identify and prioritize heat-illness prevention efforts.
The American Conference of Governmental Hygienists, an independent organization that produces guidelines for occupational health and safety, offers the 2021 Threshold Limit Values guide that takes a quantitative approach to assessing heat stress risk. If companies ask their employees to assess heat-related hazards, it will serve to better identify latent risks and contribute to mitigation measures while also grasping the challenges that rising temperatures pose regular or specific work duties.
