OSHA Launches Campaign to Prevent Heat-Related Illnesses
Acclimatization critical in preventing problems
OSHA has announced the launch of its annual Campaign to Prevent Heat Illness in Outdoor Workers. For the fourth consecutive year, OSHA’s campaign aims to raise awareness and educate workers and employers about the dangers of working in hot weather and provide resources and guidance to address these hazards. Workers at particular risk are those in outdoor industries, such as agriculture, construction, landscaping, and transportation.
“Heat-related illnesses can be fatal, and employers are responsible for keeping workers safe,” says U.S. Secretary of Labor Thomas E. Perez. “Employers can take a few easy steps to save lives, including scheduling frequent water breaks, providing shade, and allowing ample time to rest.”
The Importance of Acclimatization
Thousands of employees become sick each year and many die from working in the heat. In 2012, there were 31 heat-related worker deaths and 4,120 heat-related worker illnesses. Labor-intensive activities in hot weather can raise body temperatures beyond the level that normally can be cooled by sweating. Heat illness initially may manifest as heat rash or heat cramps, but can quickly escalate to heat exhaustion and then heat stroke if simple preventative measures are not followed. Heat illness disproportionately affects those who have not built up a tolerance to heat (acclimatization), and it is especially dangerous for new and temporary workers.
“Acclimatization is a physical change that the body undergoes to build tolerance to heat, and it is a critical part of preventing heat illnesses and fatalities,” said Dr. David Michaels, assistant secretary of labor for occupational safety and health. “Over the past three years, lack of acclimatization was the cause in 74% of heat-related citations issued. Employers have a responsibility to provide workplaces that are safe from recognized hazards, including outdoor heat.”
Last year, OSHA issued 11 heat-related citations. In some of these cases, the employer and staffing agency were cited because they involved temporary workers.
In preparation for the summer season, OSHA has developed heat illness educational materials in English and Spanish, as well as a curriculum to be used for workplace training, also available in both English and Spanish. Additionally, OSHA provides online information and resources on heat illness for workers and employers: including how to prevent it and what to do in case of an emergency.
OSHA also has released a free app that enables workers and supervisors to monitor the heat index at their work sites. The app displays a risk level for workers based on the heat index, as well as reminders about protective measures that should be taken at that risk level. Since its 2011 launch, more than 130,000 users have downloaded the app. Available for Android-based platforms and the iPhone, it can be downloaded in English and Spanish here.
In developing its inaugural national campaign in 2011, federal OSHA worked closely with the California Occupational Safety and Health Administration and adapted materials from that state’s successful campaign. Additionally, OSHA is partnering with the National Oceanic and Atmospheric Administration to incorporate worker safety precautions when heat alerts are issued across the nation. NOAA also will provide pertinent worker safety information on its heat watch Web page.
