ARC Training Tools • Alabama Retail is committed to partnering with our members to create and keep safe workplaces. • Be sure to check out all of the training tools that are available in our Safety Library. This training tool is brought to you by
Session Objectives • You will be able to: • Understand how hot conditions affect your body • Recognize symptoms of heat illness • Take precautions to reduce the risk of heat illness
What You Need to Know • Why working in hot conditions can be hazardous to your health and safety • Types of heat-related illness • Measures to prevent heat stress on the job
Body’s Cooling System • Blood circulates closer to the skin so heat is lost • Body sends sweat to the skin’s surface • Sweat evaporates off the skin, cooling the body
The Heat Equation • High Temperature • + High Humidity • + Physical Work • = Heat Illness
Additional Heat Stress Factors • Radiant heat • Air velocity
Personal Sensitivity To Heat • Acclimatization (getting used to heat) • Age • Physical condition and overall health • Metabolism • Use of alcohol
Heat Rash • Hot, humid environments where sweat can’t evaporate • Red, bumpy rash that often itches • Uncomfortable, making sleep difficult • Treatment and prevention: • Rest in a cool place • Keep your skin dry and clean
Fainting (Heat Syncope) • Worker not used to hot environment • Worker stands still in heat • Blood pools in the legs, so less blood goes to the brain • Quick recovery after lying down in cool place • Prevent by moving around a little rather than standing still all the time
Heat Cramps • Painful muscle cramps • Caused by loss of salt when sweating • Treated/prevented by drinking electrolyte liquids • Severe cases require intravenous saline solutions
Heat Exhaustion • Loss of fluids and salt • Feeling weak, dizzy, or nauseous • Skin is clammy and complexion is pale or flushed • Treatment: • Rest in cool place • Drink electrolyte solution • Severe cases: victims vomit or lose consciousness
Heatstroke • Victim stops sweating • Symptoms include hot, dry skin • Confusion, convulsions, or loss of consciousness may follow • Call for an ambulance immediately • Keep victim cool and provide fluids if conscious
Heat-Related Illness • Do you understand the information presented in the previous slides?
Heat Can Cause Accidents • Decreased strength, increased fatigue • Reduced comprehension and ability to retain information • Safety procedures not followed • Other risks
Engineering Controls • General ventilation • Spot cooling
Engineering Controls (cont.) • Shielding from radiant heat sources • Substituting machinery for manual labor
Administrative Controls • Schedule heavy work for a cooler time of year or in the evening and early morning • Allow more frequent breaks or longer rest periods • Allow time for workers to become conditioned to heat
Administrative Controls (cont.) • Reduce physical demand on workers • Use relief workers • Limit hours on hot work environments • Pace the work
PPE • Shade-providing hats • Portable water products • Reflective clothing • Systems that circulate air around the body
Medical Surveillance • Periodic medical evaluation • Determining risk of heat-related illness • Removing high-risk employees from hot working environments
Work Monitoring Programs • Check heart rate at the beginning of a rest period • Check pulse 2.5 minutes after break starts
Work MonitoringPrograms (cont.) • Take oral temperature at end of workday • Check for body water loss
Investigating Heat-Related Illness • Events leading up to the incident • Work being done at time of incident • Length of time employee working • Engineering and administrative controls • PPE • Medical surveillance and worker monitoring
Preventing Heat-Related Illness • Do you understand the information presented in the previous slides?
Water, Water, Water • Drink plenty of water all day • Drink electrolyte-balanced fluids if you sweat a lot • Drink at least one cup of fluid every 15-20 minutes when working in hot conditions • Avoid caffeine and alcohol
Key Points to Remember • Working in hot conditions can affect your health and safety • Understand the risks and the precautions • Know symptoms of heat-related illness and first-aid response • Use all available measures to reduce heat stress and keep safe and healthy when working in hot conditions
