How do you treat a heat stroke victim?  Heat stroke is a form of hyperthermia in which the body temperature is elevated dramatically. Victims of heat stroke must receive immediate treatment to avoid permanent organ damage. First and foremost, cool the victim.  Get the victim to a shady area, remove clothing, and apply cool or tepid water to the skin (for example, you may spray the person with cool water from a garden hose), fan the victim to promote sweating and evaporation, and place ice packs under the armpits and groin.  If the person is able to drink liquids, have them drink cool water or other cool beverages that do not contain alcohol or caffeine.  Monitor body temperature with a thermometer and continue cooling efforts until the body temperature drops to 101 to 102 F (38.3 to 38.8 C).  Always notify emergency services (911) immediately. If their arrival is delayed, they can give you further instructions for treatment of the victim. Extinguisher For Fire Class Extinguishing Method Water Class A Reduce the heat in fire. No sufficient heat no fire Dry Chemical Class A, B & C Disturbs the chemical reaction in a fire, thus the fire cannot sustain Carbon Dioxide(CO2) Class B and C Displacing oxygen. No oxygen no Fire. (Not preferred to use in electronic equipment) Foam(AFFF) Class B Oil Fires, Class A Farm a layer of Foam on Oil surface, So oxygen (air) is restricted to reach fuel. {AFFF (Aqueous film-forming foam)} Dry Powder Class D Metals Extinguishers agents are Mostly Specific for Mattel type and perform in different ways to put-off fire Wet Chemical Class K, Class A Chemical reacts with fat to form a soapy foam blanket over the burning oil. The water content cools the oil below its ignition temperature. How Many Step to Stop Work Authority? 1. Stop unsafe work 2. Notify Effected person 3. Investigate the cause for Incident (Accident) 4.
