Heat Stress

Transcript: The warning signs of heat exhaustion include: muscle cramps. To minimize the effects of heat exhaustion you should move to a cool shaded area. When body temperature rises above 103 degrees and your body fails to sweat to cool the body down this could indicate a heat stroke To protect against heat illness you should: perform heaviest work in coolest part of the day slowly build up tolerance to higher temperature wear light, loose-fitting, breathable clothes HEAT STRESS When using personal protective equipment like respirators or suits. Workers are at an increased risk of heat-induced illnesses when:

Heat Stress

Transcript: Heat stress can affect anyone, young or old. Although it can be fatal, but with the right training, controls and preventative measures set in place a worker should get through the day without incident. Cool the victim using the following methods; shower, spray or sponge with cool water, soak clothing with water. If it is possible, get them into a tub of room temperature water. Since heat stress more often occurs outdoors, you may need to get creative. Hydrate the victim by giving them water. Make sure that the water has no have ice, as water too cold may send one into shock. Always remember do not underestimate the hazards of heat stress. When it’s hot you need to drink lots of fluids, dress appropriately and recognize the signs of heat stress and always know how to treat when it happens. Workers will: What rights do workers have when working in hot conditions? Firstly and most importantly, if you are working in any 'at risk' situation you have the right to complain to your employer, and the Ministry of Labour without prejudice to yourself. If your employer has carried out a proper risk assessment and has sufficient controls or control strategies in place to deal with any risks arising from hot work and workplace problems, your health should not be at risk. If your employer has not carried out a risk assessment, and has no appropriate controls to deal with hot work and associated workplace problems the face immediate problems by law. Heat stress is a big concern on a job site, especially on a hot summer day. There are a number of factors that are involved in heat stress like: • Weight – Workers who are larger than their co-workers have a higher chance for heat stress • Physical condition – Being fit helps your body fight heat stress • Previous experience – If you have already experienced a form of heat stress the chances of it reoccurring are higher • Age – The older you are the less your sweat glands are effective • Heart conditions – If you have a heart condition its harder to pump blood to the skin and thus, increasing the chance of heat stress • Recent illnesses – Workers that have recently experienced an illness (diarrhea, vomiting, fever, etc.) have lost electrolytes and increased their chance for heat stress • Alcohol consumption – if the worker has consumed alcohol 24hrs prior to working they could still be dehydrated and their risk of heat stress increases • Medication – Certain medication can reduce sweating, in turn, reducing the cooling potential of your body • Lack of acclimatization – when exposed to elevated temperatures for a few days your body will adjust its self to the new environment. Acclimatization usually starts to take affect 6 – 7 days after prolonged exposure to heat. There are benefits to acclimatization Lower pulse rate and more stable blood pressure More efficient sweating Improved ability to maintain normal body temperatures TRAINING: Engineering Controls: *Engineering Controls are the most efficient way to avoid heat-stress by keeping the area around you cool* Examples: Air conditioned rooms or machinery Improved general air circulation (cooling fans) Reflective shields to redirect radiant heat Employers have a duty under clause 25(2)(h) of the O.H.S.A. to take every precaution reasonable in the circumstances for the protection of a worker. This includes developing hot environment policies and procedures to protect workers in environments that are hot because of hot processes and/or weather. The Ministry of Labour recommends the Threshold Limit Values (TLV's) for heat stress and heat strain. These values are based on preventing workers core body temperatures from rising above 38 degrees C. Majority of heat-related injuries can be prevented or the risk can be condensed. There are four forms of protection/prevention methods that can take place to ensure your safety. Scedule information sessions for employees whose work places them at risk of heat stress. Implement safe work procedures established to prevent heat-induced ilness. Determine any additional rest breaks that may be required as a result of workload and local conditions. Advise workers to drink enough fluids to replace those lost through sweating and breathing. Adhere to the recommended rest break schedule, established to avoid heat exhaustion. If the victim loses consciousness or does not respond quickly to the first aid steps above, go to an emergency room or call for an ambulance immediately. Personal Protective Equipment These are only a few examples of the controls put in place to better protect the workers health and safety. Controls will be tailored to meet the conditions of the work environment. No matter whether you work indoor/outdoor, there must be a heat stress control plan put in place in conjunction with the workplace's joint health and safety committee or worker health and safety representative. Make sure that the person does not gulp down the water, as this can also cause shock. If the person is unable

Transcript: What are some personal risk factors? In restaurants, bakeries, construction sites, manufacturing lines, industrial cleaning, ware house work, assembly lines... It is even possible to get heat stress sitting at a desk in an office, that is if the temperature is excessively hot. In which work environments is heat stress most commonly going to appear in? THE END Some personal risk factors include: Poor physical; fitness Obesity Pre-existing medical conditions chronic skin disorders alcohol and drugs Work Work load Work rate Heat stroke, which is very similar to heat stress can cause permanent damage on your organs(specifically your kidneys) and brain damage. What are some symptoms of heat stress? What is heat stress? Heat stress is a group of consequences due to overexposure or overexertion in excess environmental temperatures. Some symptoms of heat stress may include. Onset of a headache or nausea Decreased efficiency, co-ordination, and alertness. Increased irritability Light-headedness or dizziness Fainting Hands, feet, and ankles swelling, usually one to two days after first exposure. How to reduce your employees chance of getting heat stress at work(Employers) Reduce worker activity through automation or mechanization Cover or insulate hot surfaces to reduce radiant heat Shield workers from radiant heat Provide air conditioning Provide fans for spot on cooling Reduce humidity Heat stress Improve physical fitness Lower salt content in diet Enhance sweating Stay hydrated(lots of water) What are the primary factors of heat stress? Environment: Air temperature Airflow Humidity Radiant heat (e.g., sun, kiln) These 3 main factors can be a cause of heat stress. How to reduce your own risk of getting heat stress(employees) Permanent damages caused by heat stress: Worker Acclimatization Hydration Clothing Medical conditions

Young and old age people are at increased risk of suffering from heat stress due to: A. Lack of information. B. Diseases. C. Medications. D. Difficulty in remaining hydrated. Summary Medications Heatstroke is a medical emergency. Even with immediate treatment, it can be life-threatening or result in serious complications. The first thing do is to call an ambulance, then follow the first aid steps: Types Heat stroke results from prolonged exposure to high temperatures usually in combination with dehydration . Definition of heat stroke is a core body temperature greater than 105 degrees Fahrenheit (40 C) – the hall mark - , that occur after exposure to high temperatures. It is a medical emergency . صصًص Heat cramps are the intermittent, involuntary spasm of muscles that occur in an individual who is physically active in hot or humid weather. It affects the major muscles that are being stressed in the hot environment. *Heat cramps are the earliest symptoms of the spectrum of heat-related illness. Some of the difference between By Ashwaq Asiri Joud Al-Darsoni Randa bin Madi Buthainah Al-Shathri Sara Al-Khelb Sara Al-Mutairi Noir Al-Dosari Nora Al-Refayi Symptoms Heat Stroke Stay out of the sun during the hottest parts of the day, particularly 11am-3pm. If you can't avoid strenuous activity in hot weather, follow the same precautions and rest frequently in a cool spot. Try to schedule exercise or physical labor for cooler parts of the day, such as early morning or evening. If you feel your abilities start to diminish, stop activity and seek out a cool shaded place. Taking breaks or Work-rest cycles give the body an opportunity to get rid of excess heat, slow down the production of internal body heat, and provide greater blood flow to the skin. 5. What is the hall mark symptom that appears in heat stroke: A. Nausea and vomiting. B. Rapid weak pulse. C. High body temperature (40 c). D. Flushed dry Children Advance Symptoms -Significant sweating - Involuntary spasm of the large muscles in the body *When any other symptoms happened, individuals may suffer from heat exhaustion. Get acclimatized Heat Stress Stop all activity and rest Move to a cooler place Drink cool water or sports drinks Remove any tight or unnecessary clothing. Take a cool shower, bath, or sponge bath. Apply other cooling measures such as fans or ice towels. Situations that require exertion in hot weather. is a heat-related illness that can occur after you've been exposed to high temperatures for several days and have become dehydrated. Check the person's rectal temperature and try to reduce it to (39 C) -If a child has stopped breathing, begin rescue breathing Questions Time Drink plenty of fluids to replace fluids lost during sweating. So, Staying hydrated will help your body sweat and maintain a normal body temperature. Drink BEFORE you are thirsty. Replace lost electrolytes such as sodium, potassium and magnesium with food or a sports drink. Eat cold foods, such as salad and fruit, which have a high water content. Do not drink alcohol or beverages with caffeine. become dehydrated Dehydration A lack of air conditioning. Sudden exposure to hot weather Genetic response to heat stress. Lack of information Heat exhaustion 3. Which one of the following is a symptom of heat cramps: A. Headache. B. Nausea and vomiting. C. Significant sweating. D. Fever. Prevention About Heat Stroke 2. Which one of the following is an immediate skin reaction after sun overexposure: A. Skin Blisters. B. Skin hotness. C. Skin peeling. D. Scars. Heat stroke is also known as sunstroke, thermic fever. It is the last stage of Heat stress. It is the most serious form of heat injury and it is a medical emergency that usually follows heat cramps and heat exhaustion. Heat stroke can come on suddenly, but warning symptoms often appear first. Some medications can raise the risk of heat stroke like : Beta blockers - Diuretics . Skin turns red in as little as 30 minutes but most often takes 2 to 6 hours Treatment High body temperature (40C) "The Hall Mark" Wear loose-fitting, lightweight clothing to allow sweat to evaporate. Wear light-colored clothing if you're in the sun. Dark clothing absorbs heat. Wear a hat with a brim to keep the sun off head and face. Use sunscreen to prevent sunburn, which can limit the skin's ability to cool itself. If you are going to work or exercise in hot weather, it's important to acclimatize to the heat for about a week before beginning any intense exercise or work. This allows your body to gradually adapt to the heat. 1-Water depletion; Signs include excessive thirst, weakness, headache, and loss of consciousness. 2-Salt depletion; Signs include nausea and vomiting, frequent muscle cramps, and dizziness. Although heat exhaustion isn't as serious as heat stroke, it isn't something to
