Heat Illness Prevention

Review and understand the regulation Review and understand heat illness preventive measures Increase awareness and commitment to safety and health at the work sites Training Goals

Heat Related Deaths Since 1936, 30,000 people have died from heat related illnesses 384 people die each year from heat stroke Heat related injuries occur more often with: – the elderly – people who are not in good physical condition; or – acclimatized to the heat. Source: National Safety Council

Two ways our bodies produce heat: 1.Metabolic Heat The body generates heat through the digestion of food, work and exercise. 2.Environmental Heat Body absorbs heat from the surrounding environment

The Body’s Cooling Systems Convection: the transfer of heat through the circulation of air (wind or a fan). Evaporation: the process which occurs when a liquid changes into a vapor (sweating). Radiation: heat is naturally emitted from the body surface.

Conditions Affecting the Cooling System Temperature: The hotter it is, the hotter it feels! Air Velocity: Wind can cool you Humidity:The amount of water vapor in the air affects the rate of evaporation Clothing:Type of clothing affects the amount of heat we absorb Metabolic Load:How hard you are working) Radiant Heat:Sun light or other sources Personal:Some do not sweat; some are more susceptible; skin pigment

Heat Illness Serious Medical Conditions resulting from the body’s inability to cope with a heat load. – Heat Rash – Heat Cramps – Heat Exhaustion – Heat Syncope – Heat Stroke

How do we gauge heat?

Heat Rash Produces a rash which in some cases causes severe pain, insomnia, or permanent disability Occurs in hot, humid environments where sweat can't easily evaporate from the skin.

Heat Cramps Muscle spasms in the arms, legs, and stomach Caused by the loss of salt and fluids through heavy sweating or lack of rehydrating.

Heat Exhaustion When the body's cooling system struggles to compensate in high temperatures and dehydration. Symptoms include heavy sweating, cool moist skin, and a weak pulse. A victim of heat exhaustion may begin to feel weak, clumsy, confused, or upset.

Heat Syncope (Fainting) Heat syncope, or fainting, can occur if a worker is not acclimatized to heat and if the worker stands still rather than moving around.

Heat Stroke – potentially life threatening The body's internal thermostat can no longer deal with the stress caused by heat. The body quickly stops sweating and begins storing heat. Symptoms include lack of sweating, hot dry skin, and a rise in body temperature to 105° or higher. The victim may become weak and dizzy, confused nauseated, or fall unconscious

Confusion is Common At all levels of illness confusion is a possible symptom You may not recognize when you become ill Call your supervisor if you begin to have symptoms

Treatment For Heat Illnesses Treat heat cramps by resting in a cool place and slowly drinking water. A victim of Heat Exhaustion or Heat Stroke should be moved to a cool area, loosen or remove excess clothing, slowly drink water, and fan and spray them with cool water. Heat Stroke call 911 and contact your supervisor

Who may be effected Grounds Workers Athletic Field Workers Pool Technicians Irrigation Workers Grounds Equipment Operators Maintenance Workers Custodians Athletic Coaches/Trainers Teachers/Substitutes Campus Security/Monitors or Playground Supervisors

Personal Risk Factors Age (very young and elderly are more affected) Personal Health/Fitness/Obesity and other Health Conditions Personal Stress Dehydration Alcohol Use Certain Drugs, Medications, or Supplements Lack of Acclimatization to Hot Weather or Hot Weather Work

Environmental Risk Factors Job Related – Duration of Activity – Metabolic Load (how strenuous the work is) – Wearing Heavy Attire or Protective Clothing (PPE) Environmentally related – Temperature – Humidity – Air Velocity – Radiant Heat Sources (sunlight, reflection, etc.)

Heat Illness Prevention Hydration – Keeping yourself well hydrated can keep you from experiencing the effects of heat illness. Acclimatization – Working for shorter periods of time in the heat until you build up a tolerance. Whether you’re coming from a different climate or at the beginning of the summer. Cool Down/Shade – Taking your rest break in the shade, taking additional breaks if you feel fatigued or begin to feel symptoms of heat illness.

The Buddy System When its hot, work with a buddy, check on each other regularly. If you can’t work with a buddy, take a radio and check in frequently.

PREVENTING HEAT-RELATED HEALTH PROBLEMS Dress Light – Lightweight, light- colored clothing reflects heat and sunlight and helps your body maintain normal temperatures. Wear loose-fitting clothes such as cotton which lets air move over your body. Wide brimmed hats should also be worn.

Proper Diet – Eat light Avoid heavy foods Eat smaller, well-balanced meals more often Rest Periods – Pace activities slower during high heat Frequent rest in shade Drink plenty of fluids

Drink How Much? Drink until “urine” is clear. If your urine is yellow or dark yellow, you are not drinking enough fluids!

Hydration Loss of fluids is a major contributor to heat illness. Thirst isn't a reliable indicator of the body's need for fluids. When you’re thirsty, you're already dehydrated.

Hydration 1.6 quarts of fluid per hour can be lost through sweating. Health experts recommend drinking 8 ounces of fluids for every 20 to 30 minutes of work being performed.

Hydration How can you re-hydrate during the work day? All schools have running water, find a water fountain, take a drink, fill a bottle. If working away from a building (landscaping), fill an igloo with water and ice before heading out and take it with you. Drink often - 8 oz. every 20 minutes

Acclimatization Working in the heat, whether you’re new to the job or it’s a sudden heat spell can be difficult. Over a one week period, work up to full days working in the heat. An acclimatization period may also be necessary upon return from vacation or other extended periods away from the workplace.

Breaks/Shade Take more frequent breaks when working in extreme temperatures or at the first sign of heat stress symptoms. Try to schedule tasks around the weather. Complete more physical tasks in the morning and evening when the sun isn't at its peak and the temperature is cooler. Reduce manual labor by using mechanical assistance when possible.

Breaks/Shade/Cooling Move to shaded areas Move to cool indoors Move to a cooled vehicle Use fans Use moist cloths

Breaks/Shade Where to find shade at a school site? – Next to a building – Under a tree – Sun Umbrella (Playground Supervisor) – Easy Up (Maintenance) – Cooled Vehicle (Maintenance/Landscaping) – Inside a cooled building

When to take precautions Any time the temperature reaches 80 degrees Fahrenheit, precautions should be taken. Ensure you will be on a campus with running water or take water with you. Ensure you know where to take a break – Shade areas – Cooled buildings – Cooled vehicles
