  1. Mountain Safety

  2. MS 1_6: FA Basics (Dehydration & Heat Illnesses)

  3. Learning Intention: To equip you with the knowledge to avoid and treat heat illnesses.

  4. Success Criteria: By the end of this session everyone should be able to: • Describe what steps to take to avoid, recognise and treat heat-related illnesses when walking.

  5. Activities: • Discussion/Powerpoint: • - What is a heat illness? • - What can you do to avoid them? • - How should you treat them? • 2. Scenario

  6. What is a heat illness?

  7. American Meteorological Society Central North Carolina Chapter April 21, 2005 Heat Illnesses (“Hyperthermia”) • Heat rash • Sunburn • Heat cramps • Heat exhaustion • Heat stroke Severity

  8. Heat Rash (prickly heat) Symptoms: Skin becomes reddened and may itch, feel prickly or hurt. First Aid: Practice good personal hygiene; keep the skin clean and the pores unclogged, allow skin to dry, wear loose clothing.

  9. Sunburn Symptoms: Skin becomes reddened, pain, blistering in severe cases. First Aid:Move into shade or cover minor burns with light cloth, frequent sips of water, cool skin by sponging with water, apply after-sun.

  10. Heat Cramps: Symptoms: Cramping of either active muscles (arms, legs) or involuntary (usually abdominal) muscles (or both). First Aid: Replenish electrolytes through drinking of fluids such as sports drinks etc. Rest in a cool environment.

  11. Heat Exhaustion: Symptoms: Nausea, dizziness, weakness headache, blurred vision, profuse sweating, cold/wet (clammy) grayish skin, unconsciousness, coma and death. First Aid:Lie down in a cool location, administer fluids if conscious. If unconscious, seek medical care.

  12. Heat Stroke: Symptoms: Chills, restlessness, irritability, euphoria, red face and skin, disorientation, hot/dry skin (not always), collapse, unconsciousness, convulsions and death. First Aid: Immediate, aggressive cooling of the victim’s body using wet cloths, immersion into cold water or alcohol wipes. Contact emergency services ASAP!

  13. Avoidance

  14. Sun-hat and or sun-screen • Remove clothing layers • Stop & rest • Move into shade • Drink little & often to avoid dehydration

  15. Dehydration taken from: OH&S Canada Volume 69, Number 5, page 52, May 2000

  16. What to drink: • Water is the best; juices are also good (juices contain energy restoring glucose). • Electrolyte (sports) drinks (e.g. Powerade) are usually not needed (but can be used for first aid for cramps). • Stay away from caffeinated carbonated, diet drinks and alcohol as they take water out of your body.

  17. How Much Water is Enough? • More than you want just to satisfy your thirst • Sources of water are: 1. Fluids – ½ pint = 250 mL every 30-60 min 2. Foods - fruit & veggies are 90% water • Not too cold

  18. Eat Healthily You can and should replace essential elements lost during sweating; Eat a balanced diet rather than taking salt tablets or drinking expensive sports drinks.

  19. Watch out for each other! • Someone heading into a heat stroke will no longer realise what is happening to him/her • It is vital that group members be able to recognise what is happening and intervene • Without quick attention, the person may die!

  20. Treatment

  21. General advice: • Lie down in shade • Sip water • Remove outer clothing • Cool with damp cloth, especially head & neck
