If you sweat a lot, you should appropriately supplement some sodium and potassium.
（2） Precautions for high temperature construction (1) wear various protective equipment according to the operation needs to prevent sunlight exposure.
(7) Avoid working alone in harsh conditions.
Outdoor construction shall avoid direct sunlight on the head and direct absorption of radiant heat by the skin; (2) Those suffering from hypertension, anemia, heart disease and nervous system diseases should not be engaged in high-temperature and high-altitude operation; (3) If necessary, use local air supply devices such as air supply fan, spray fan or air shower in high-temperature workplaces to prevent heatstroke; (4) Pay attention to replenish water in time.
Drink water at any time.
High temperature and heat in summer, relatively poor construction site environment, high labor intensity of construction personnel, prone to excessive fatigue and heatstroke, which is a period of frequent accidents.
Sodium can be supplemented by adding salt and soy sauce to food.
Don’t wait for thirst.
In order to ensure safe construction operation in high temperature season, combined with the unsafe situation in high temperature season, the following precautions for high temperature heatstroke prevention are summarized: (1) preparation for high temperature heatstroke prevention (1) establishment of high temperature heatstroke prevention emergency team; (2) Publicize heatstroke prevention knowledge to construction personnel; (3) Reasonably arrange working hours and avoid high temperature periods; (4) Provide emergency drugs, such as cold medicine, anti-inflammatory medicine and other therapeutic drugs, as well as health food such as Rendan, cooling oil and chrysanthemum tea; (5) Do a good job in sanitation and epidemic prevention.
Foods with high potassium include bananas, bean products, kelp, etc; (5) Try to avoid drinking water with low temperature; (6) Avoid excessive fatigue and ensure adequate sleep.
（4） Emergency measures for heatstroke (1) those with heatstroke aura and slight heatstroke should immediately leave the high-temperature working environment, rest in a cool, quiet and ventilated place, loosen their clothes, and drink sunstroke reducing drinks such as mung bean soup and herbal tea; (2) Patients with severe heatstroke should be given first aid.
（3） Heatstroke symptoms (1) a lot of sweating, thirst, physical weakness, inattention, normal or slightly high body temperature, which is a precursor of heatstroke symptoms, we should pay attention to; (2) Feel dizzy and weak, flush, chest tightness, shortness of breath and slightly high body temperature.
This is mild heatstroke, which should be rescued in time; (3) Coma, spasm and high body temperature are severe heatstroke, which may be life-threatening if not treated in time.
First put the patient in a cool and ventilated place, untie his clothes for breathing, then place ice bags on the patient’s head, armpits and groin area for cooling, then wipe his body with ice water, cold water and alcohol to reduce the body temperature, and massage his four limbs for smooth blood circulation; (3) People suffering from heatstroke should avoid drinking a large amount of water and should drink a small amount of more than 300} ml each time; (4) Patients with serious illness should be sent to hospital as soon as possible…
