HEAT STRESS

1. Welcome • Training Title: Heat stress awareness • Trainer Name: Syed Neyaz Ahmad • Mobile # 056-3671957 • Email: neyaz.qhse@gmail.com

3. What is heat stress? • When work is being performed in elevated temperatures and our body system failed to maintain the normal body temperatures. • Employee must recognize and treat with heat stress. • When the body loses fluids become unable to cool itself by sweating & several heat induced illness such as heat stress or heat exhaustion and the more severe heat stroke can occur and can result in death

5. Symptoms of heat stress • Headache, • Dizziness, • Weakness, • Nausea, • Fainting, • Colored urine, • Inability to think straight, • Upset stomach, • Clammy skin, • Moist skin, • Mood change such as irritability or confusion • People can take precautionary measures to avoid the heat stress

6. Symptoms of heat stress • Red, Hot, Dry Skin, Although the Person May Have Been Sweating Earlier; • Confusion; • Extremely High Blood Pressure, • Rapid Respiratory and Pulse Rate; • Unconsciousness or Coma. • If you find these type of symptoms immediately take medical help otherwise it may be Dangerous for individual life

7. Measuring Instrument / Don’t work alone

8. Factors of Heat stress Factors leading to heat stress: • High temperature and humidity • Direct sun or heat • Limited air movement • Physical exertion • Poor physical condition

9. Action / Precautions What to do a victim: • Move the worker to cool & shaded area • Loose and remove heavy clothing • Provide cool drinking water • Fan & mist the worker with water • Casualty must be cooled down and medical aid sought immediately with the person • Transported to the site medical facilities.

16. Heat Index/Precautions Heat Index - Work-Rest - Water Requirement - Other Controls 27 – 31 Caution 50 – 10 One cup of water every 30 minutes Continues monitoring of workers 32 – 38 Extreme Caution 40 – 10 One cup of water every 30 minutes No work alone 39 – 53 Danger 30 – 10 One cup of water every 15 minutes Work under shade • + Extreme Danger Strictly follow the U.A.E. Mid day break rule 12.30 – 3.00 pm

17. Thermoregulation Normal body temperature: Optimal conditions for cellular reactions in the human body include a core body temperature of approximately 37°C

18. Precaution of heat stress • Drink plenty of water • 2 cup of cool water every 30 minutes even not thirsty • Avoid to take Tea, Coffee, Alcohol and soft drinks which can dehydrate your body • Incorporate vegetables & Fruits in your food to avoid heat stress • Begin drinking fluid early in the day. Waiting until the hottest portion of the day to replenish fluids is too late. • Avoid caffeine, sugary or carbonated drinks and alcohol the night before and during the day.

19. Precaution of heat stress • Encourage people to wear light weight, light colored & loose fitting cloth • Plan your job make heavier job in morning hour • Take frequent short brakes / rotate tasks Prevention is better than cure: • Avoid to take heavy meal • Adequate /enough Sleep In Night • Don’t work alone • Deep care of person 14 days or 24 hrs. off from duty

20. Types of Heat Stress Heat Stroke • Heat stroke is an acute and dangerous reaction to heat stress caused by a failure of the heat regulating mechanisms of the body, e.g. a breakdown of the employee’s temperature control system that causes sweating. • Body temperature rises so high that brain damage and death will result if the person is not cooled quickly. • Heat stroke, also known as sun stroke, is a type of severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F) and confusion.

21. Symptoms of Heat Stroke: • Throbbing headache. • Dizziness and light-headedness. (headache) • Lack of sweating despite the heat. • Red, hot, and dry skin. or damp skin • Muscle weakness or cramps. • Nausea and vomiting. • Rapid heartbeat, which may be either strong or weak. • Rapid, shallow breathing

25. Heat Exhaustion • Heat exhaustion is a state of very definite weakness or exhaustion caused by the loss of fluids from the body. • This condition is much less dangerous than heat strokes, but must be treated early on to prevent eventual deterioration to heat stroke. • Heat exhaustion is a condition whose symptoms may include heavy sweating and a rapid pulse, a result of your body overheating. • It's one of three heat-related syndromes, with heat cramps being the mildest and heatstroke being the most severe.

26. Heat Exhaustion Symptoms: • Moist skin, • Profuse perspiration, • Extreme weakness. • Breathing is shallow. The most common signs and symptoms of heat exhaustion include: • Confusion. • Dark-colored urine (a sign of dehydration) • Fatigue. • Nausea, vomiting, or diarrhea.

28. Heat Cramps • Heat cramps are caused by perspiration that is not balanced by adequate fluid intake. • Heat cramps are often the first sign of a condition that can lead to heat stroke. • Heat cramps, a type of heat illness, are muscle spasms that result from loss of large amount of salt and water through exercise. Heat cramps are associated with  cramping in the abdomen, arms and calves. • This can be caused by inadequate consumption of fluids or electrolytes.

30. Heat Rash • Heat rash is caused by continuous exposure to heat and humid air and is aggravated by chafing clothes. • The condition decreases ability to tolerate heat. • A heat rash occurs when sweat ducts become clogged and the sweat cannot get to the surface of the skin. Instead, it becomes trapped beneath the skin's surface causing a mild inflammation or rash. Heat rash is also called prickly heat or miliaria. Picture of the layers of the skin including the sweat glands. Symptoms: Mild red rash, especially in areas of the body in contact with protective gear.
