3 Outdoor Heat Exposure – Employee Training The following 8 slides contains Table 1 with the outdoor temperature action levels, the supervisor training requirements, and the employee training requirements from the Outdoor Heat Exposure standard for background information. You can use the provided quiz to start the training or use another method to capture the audience’s attention.There are slides towards the end of the presentation for you to fill in employer specific information.
4 Information and training All training must be provided:To employees and supervisorsIn a language the employee or supervisor understands,Prior to outdoor work at or above the temperatures listed in WAC (2) Table 1, andAt least annually thereafter.
5 Outdoor Temperature Action Levels Table 1To determine which temperature applies to each worksite, select the temperature associated with the general type of clothing or personal protective equipment (PPE) each employee is required to wear.Note: There is no requirement to maintain temperature records The temperatures in Table 1 were developed based on Washington State data and are not applicable to other states.All other clothing89 degrees FDouble-layer woven clothes including coveralls, jackets and sweatshirts(Note: also regular rain gear)77 degrees FNon-breathing clothes including vapor barrier clothing or PPE such as chemical resistant suits52 degrees F
6 Information and training (2) Supervisor trainingPrior to supervising employees working in outdoor environments with heat exposure at or above the temperature levels listed in WAC (2) Table 1, supervisors must have training on the following topics:
7 Information and training for supervisors The information required to be provided in subsection (1) of this section;The procedures the supervisor must follow to implement the applicable provisions of WAC through ;The procedures the supervisor must follow if an employee exhibits signs or symptoms consistent with possible heat-related illness, including appropriate emergency response procedures;Procedures for moving or transporting an employee(s) to a place where the employee(s) can be reached by an emergency medical service provider, if necessary.
8 Information and training Employee training.Training on the following topics must be provided to all employees who may be exposed to outdoor heat at or above the temperatures listed in WAC (2) Table 1:
9 Information and training for employees The environmental factors that contribute to the risk of heat-related illness;General awareness of personal factors that may increase susceptibility to heat-related illness including, but not limited to, an individual’s age, degree of acclimatization, medical conditions, drinking water consumption, alcohol use, caffeine use, nicotine use, and use of medications that affect the body’s responses to heat. This information is for the employee’s personal use;
10 Information and training for employees The importance of removing heat-retaining personal protective equipment such as non-breathable chemical resistant clothing during all breaks;The importance of frequent consumption of small quantities of drinking water or other acceptable beverages;e) The importance of acclimatization;
11 Information and training for employees f) The different types of heat-related illness and the common signs and symptoms of heat-related illness; andg) The importance of immediately reporting signs or symptoms of heat-related illness in either themselves or in co-workers to the person in charge and the procedures the employee must follow including appropriate emergency response procedures.
12 Quick Quiz – True or False Cola drinks are the best way to hydrate when you are working outside.Light colored clothing is better than dark when working in the sun.Your medicine may make you more vulnerable to heat-related illness.It is important to drink your water all at once.Answers:1. False2. True3. True4. False
14 Why is it important to know about and address outdoor heat exposure? Hot weather can cause mental and physical fatigueExtra care is needed when working and drivingHeat exposure can cause heat-related illness under certain conditionsHeat-related illness:Happens when the body is not able to cool itself and the body overheatsCan cause injury, disability or deathIs preventableNASA
15 Where does heat illness happen? Heat illness can affect anyone.It can happen in logging, construction projects, landscaping, agriculture, field work, transportation, etc.
16 Environmental factors that contribute to the risk of heat-related illness
17 Environmental Factors Direct sun, heat and humidityMore direct sun the greater the riskLimited air movementLow or no wind
18 Environmental Factors Hot equipmentEngines add more heatHeat reflected from ground or objectsWatch out for reflected heat
19 Environmental factors Physical exertionWhat kind of work are you doing?How hard are you working?Photo credit:
20 Workload ActivityCategoriesExample ActivitiesRestingSitting quietlySitting with moderate arm movementLightSitting with moderate arm and leg movementsStanding with light work at machine or bench while using mostly armsUsing a table sawStanding with light work at machine or bench and some walking aboutDriving a tractor (at times can be moderate)
21 CategoriesExample ActivitiesModerateScrubbing in a standing positionWalking about with moderate lifting or pushingWalking on level at about 4 miles/hr while carrying 6-7 pound weight loadHeavyCarpenter sawing by handGoing up and down laddersChopping weedsHeavy assembly work on a non-continuous basisIntermittent heavy lifting with pushing or pulling (e.g. pick-and-shovel work)Very HeavyShoveling wet sandBucking hay balesHand chopping hops vines
22 Environmental factors Clothing and Personal Protective Equipment (PPE)Heavy clothingMultiple layersDark colored clothingProtective ClothingVapor barrier clothingChemical resistant suitsRespiratory Protection
23 Personal factors that may make you more susceptible to heat-related illness
24 Personal risk factors Dehydration Failure to drink enough water can make you dehydratedLoss of electrolytesWhen you sweat you lose electrolytesElectrolytes are needed for your body to functionIllness/fever
25 Personal risk factors Age, weight, and personal fitness Past heat-related illnessMedical conditionsHeart conditionsDiabetesEtc.Certain medicationsSee next slideAge over 40, overweight, and poor fitness increase the risk of heat illness.
26 Some medications can make you more sensitive to the effects of heat. Allergy medicines (antihistamines)Cough and cold medicinesBlood pressure and heart medicinesIrritable bladder or bowel medicinesLaxativesMental health medicinesSeizure medicinesThyroid pillsWater pills (diuretics)A health care provider or pharmacist can tell you for sure.
27 Diet Personal risk factors Sugar added drinks Heavy foods Alcohol Hangover
28 Don’t fall for these beliefs – we want you healthy! Personal risk factors“I’m tough ~ I don’t need a water break”“I’m not thirsty ~ I don’t need to drink”“I’ll lose pay if I take a water break”“I’ll be letting my team down”“I’m new here ~ I need to prove myself”POSSIBLE WORKPLACE DISCUSSIONS – IMPORTANT THAT LEADERS SUPPORT HEAT STRESS PREVENTION MEASURESdiscussion of how protective gear can be inconvenient and uncomfortable - and how to minimize these problems;how economic and other pressures of crop production can cause employers and workers themselves to resist interrupting work, even when heat stress conditions become hazardous;how some workers deliberately limit the amount of water they drink;and how flexibility and the use of experience and good judgment are important when setting work/rest cycles.Don’t fall for these beliefs – we want you healthy!
29 Helpful tips for working in the heat – Work smart Have a “Buddy System” to keep an eye on co-workers for symptoms of heat illness such as crankiness and denialIncrease breaks if:Conditions are very hot; orHigh exertion levels; orProtective clothing limits evaporative coolingAlternate heavy work with light work when possibleWhen possible, schedule the hardest work for the cooler parts of the day
30 Helpful tips for working in the heat - Work smart Work in the shade or out of direct sun when possibleAvoid getting sunburnedWear proper clothingLight coloredLight weightNatural fibersHat with a brimCooling vest may be helpful in some cases.
31 Remove PPE and excess clothing during breaks This is important to help you stay cool
32 WaterIt is important to drink small quantities of water throughout the day.One quart or more over the course of an hour may be necessary when the work environment is hot and you may be sweating more than usual as you work.Employers are responsible for encouraging water consumption.Employees are responsible for monitoring their own personal factors for heat-related illness including consumption of water or other acceptable beverages to ensure hydration.
33 Proper hydration is key to preventing heat illness DODrink plenty of waterStart work well hydratedConsider sports drinks for electrolyte replacement when sweating a lotAVOIDDrinking pop and other sugary drinksDrinking lots of coffee and teaDrinking alcoholWaiting for thirst before drinking waterBy “hydration” we mean drinking enough water. If you become dehydrated, heat illness can occur.The most effective way for preventing heat stress is to steadily replenish the water that the body loses as sweat.Drinking a large amount of water all at once after sweating heavily for a long time is not as effective and can even be dangerous.About 1 quart every hourCool liquids are better than ice coldSupply adequate water and encourage employees to drink regularly.Workers in restricted environments (sewers, etc.) should drink before entry and at regular intervals.
34 Drinking water sources: Closeable & have tapClearly markedSuitably cool (60 degrees Fahrenheit or less)Individual cupsNote: Suitably cool water should be sixty degrees Fahrenheit or less. During hot weather, employees may require up to three gallons of water per day.With this water consumption comes a need to use the bathroom. Facilities need to be available and workers must be given the opportunity to use them as needed.Other options:Bottled waterHydration packs (“camelbacks”)Lightweight bags carried on the back. Users sip water through a tube.Hydration packWorker wearing hydration pack
35 AcclimatizationWhen people are not used to being in the heat they need to adjust (acclimate) to hot working conditions over a few days.In severe heat, gradually build up exposure time especially if work is strenuous.Eastern WA workers experience more heat and are better acclimated.Western WA workers experience heat less often and do not have the opportunity to acclimate.Pay special attention to:New employeesPeople just back from being sickAnyone absent for more than 2 weeksPeople who have just moved from a cooler climateEveryone during heat wave events
36 Types of Heat Illnesses There are five main kinds of heat illness:Heat rash – often under clothingHeat cramps – in arms or legs with physical labor. Can be caused by the loss of electrolytes from sweating.Fainting – can occur when person not used to heatHeat exhaustion – more serious effectHeat stroke – can be fatal
37 Heat exhaustion and Heat stroke What are the most serious heat illnesses?Heat exhaustion and Heat strokeHeatExhaustionHeatStrokeDehydrationHeat exhaustion and heat stroke occur when the body becomes dehydrated – loses too much water.NOTE: pesticide poisoning and heat stroke have similar symptoms. This is more likely to occur in agriculture. If there is any doubt about the illness, get medical help immediately. Both pesticide poisoning and heat stroke can be life-threatening and require prompt treatment.Untreated heat exhaustion may progress to heat stroke.Symptoms of either should always be taken seriouslyNote:Heat exhaustion or heat stroke may develop over a few days.
38 Heat-related illness: Signs, symptoms, and response Signs and SymptomsResponseHeat rashRed blister-like eruptions/bumpsItching (prickly sensation)Rest in a cool place.Allow the skin to dry.Monitor for infection.Heat CrampsPainful spasmsAbnormal body postureGrasping the affected areaDrink water or a heavily diluted sports beverage (such as Gatorade).Seek medical attention if cramping is severe or does not go away.
39 Heat exhaustion: Signs and symptoms IllnessSigns and SymptomsHeat exhaustionHeadaches,Dizziness, light-headedness, or faintingWeakness,Mood changes, irritability or confusionFeeling sick to your stomach and/or vomitingExtreme sweatingDecreased and dark-colored urinePale clammy skin
40 Heat exhaustion: Response • Move the person to a cool, shaded area. Don’t leave the person alone. If the person is dizzy or light-headed, lay him on his back and raise his legs about 6-8 inches. If the person is sick to his stomach, lay him on his side.• Loosen and remove heavy clothing.• Have the person drink some cool water (a small cup every 15 minutes) if he is not feeling sick to his stomach.• Try to cool the person by fanning him. Cool the skin with a cool spray mist of water or wet cloth.• If the person does not feel better in a few minutes call for emergency help (ambulance or 911.)If heat exhaustion is not treated, the illness mayadvance to heat stroke.
41 Heat stroke: Signs and symptoms IllnessSigns and SymptomsHeat strokeDry, pale skin,Sweating may still be presentNausea and vomitingHot, red skin (looks like sunburn)Mood changes, irritability, confusion, and not making any senseSeizures or fitsCollapse (will not respond)High temperature (104° F or higher)
42 Heat Stroke or Heat Exhaustion? The telling difference is mental confusion/disorientation in ALL heat stroke victims.You can ask these 3 questions."What is your name?""What day is this?""Where are we?"If a worker can’t answer these questions,assume it is heat stroke.How do you tell the difference??
43 Heat stroke: Response - A Medical Emergency Call for emergency help (ambulance or 911)Move the person to a cool, shaded area. Don’t leave the person alone. Lay him on his back and if the person is having seizures, remove objects close to him so he won’t hit them. If the person is sick to his stomach, lay him on his side.Remove heavy and outer clothing.Have the person drink small amounts of cool water if he is alert enough to drink anything and not feeling sick to his stomach.Try to cool the person by fanning him or her. Cool the skin with a cool spray mist of water, wet cloth, or wet sheet.If ice is available, place ice packs in armpits and groin area.
44 Important!Stop all activity if you become:LightheadedConfusedWeakFaintOr have a pounding heart or trouble breathingTell the person in charge if you or one of your co-workers experience symptoms of heat-related illness.
