Precautions for preventing heatstroke during high temperatures in summer

At present, we have entered the high-temperature season of midsummer. The environmental temperature at the construction site is high, the working conditions are relatively harsh, the labor intensity of construction workers is high, and they are prone to excessive fatigue and heat stroke. It is a period prone to accidents. In order to ensure safe construction operations in high-temperature seasons, and based on the heat stroke that is likely to occur during construction in high-temperature seasons, the following precautions for preventing heat stroke are summarized:

1. Precautions for preventing heat stroke during high-temperature seasons

1. Each team should arrange their work and rest time reasonably, and adopt the method of "working at both ends and resting in the middle" or rotating work to avoid high-temperature sunlight exposure, fatigue work and prevent employee heatstroke. In order to prevent workers from heat stroke and various production safety accidents caused by high temperature during the construction process, the team must be equipped with heatstroke prevention and cooling drugs such as Rendan, Shidishui, Huoxiang Zhengqi water, Fengyoujing, etc. In addition to emergency repairs, each team can reasonably arrange work according to the project volume, avoid hot periods, and take advantage of the cooler times in the morning and evening to carry out construction.

2. Avoid working alone under harsh conditions.

3. Those who work in the open air and at high temperatures should drink more tea and refreshing drinks with a salt concentration of 0.1 to 0.3%, but avoid excessive drinking. It is best not to exceed 300 ml at a time.

4. Strengthen personal protection. It is strictly forbidden to work shirtless or wearing slippers at the construction site. Inspections on the wearing and use of safety protective equipment will be strengthened to ensure the true implementation of labor protection measures. Take sun protection measures and avoid direct sunlight on the head during open-air construction to avoid direct absorption of radiant heat by the skin.

2. Symptoms and emergency measures of heatstroke

1. Symptoms of heatstroke

(1) Premonition of heatstroke. The symptoms are: after working in a high-temperature environment for a period of time, there will be a lot of sweating, thirst, physical weakness, inability to concentrate, and uncoordinated movements. Under normal circumstances, the body temperature is normal or slightly elevated at this time, but It won't exceed 37.5 degrees.

(2) Mild heat stroke. The symptoms are: in addition to the symptoms of aura of heat stroke, there may also be dizziness and fatigue, flushed complexion, chest tightness and shortness of breath, burning and dry skin, and body temperature rising to above 38.5 degrees. If timely rescue is not provided at this time, heat syncope or heat collapse will occur.

(3) Severe heat stroke. It is generally caused by mild heatstroke (patients) who are not treated in time and properly, resulting in serious deterioration of the condition, followed by coma, convulsions or twitching of hands and feet. At this time, the skin of heat stroke patients is often dry and sweatless, and the body temperature rises to above 40 degrees. If emergency treatment is not given immediately, life safety may be endangered.

2. Emergency measures in the event of heat stroke

(1) Those who have signs of heat stroke or mild symptoms: Immediately leave the hot working environment and go to a cool, quiet and well-ventilated place to rest and relax. Undress and drink cool drinks (light salt water or strong tea).

(2) People with severe or high fever need first aid: a. Cool down quickly, place the patient in a cool and ventilated place, and untie the clothes. b. Ice packs can be placed on the patient's head, armpits, groin area, etc. c. Use ice water, cold water or alcohol to wipe or spray the body. Finally, the body temperature is reduced to about 380C and prevents the temperature from rising again. d. Massage the limbs to prevent blood stasis.

(3) People with heat stroke should avoid drinking large amounts of water. They should drink small amounts of water multiple times, preferably no more than 300 ml each time. Don’t binge drink. Because drinking a lot of water will not only dilute gastric juice, thereby affecting digestive function, but also cause hyperreflexia and perspiration. As a result, a large amount of water and salt in the body will be lost, and in severe cases, it can promote the occurrence of heat cramps.

(4) In addition to the above treatments, patients with heat cramps should be given salty drinks and, if possible, intravenous infusion of 500 to 1000ml of normal saline.

(5) For patients who are seriously ill, all means must be used immediately to send the patient to the hospital as soon as possible.

3. How to prevent heat stroke

1. Do not work for too long under high temperatures, and try to use rotation or intermittent work;

2. Reduce labor intensity and prepare for It is best to drink heatstroke prevention and cooling drinks, and try to add light salt boiled water or salty drinks as much as possible;

3. Ensure adequate sleep and eat more nutritious fruits and vegetables;

4. Try to wear Breathable, heat-dissipating cotton clothes;

5. Do not drink strong alcohol.

6. Drink water at any time, do not wait until you are thirsty. Do not eat too much cold drinks to prevent gastrointestinal vasoconstriction and affect digestive function.

4. Precautions for drinking water in summer

The weather is hot, and people must master the skills of drinking water when working outdoors to avoid "water intoxication".

1. Drink an appropriate amount of light salt water. Drinking some light salt water when working outdoors can replenish the inorganic salts taken away by the large amounts of sweat excreted by the human body. The most convenient way is to add 1 gram of salt to 500 ml of drinking water and drink it in due course. This can not only replenish the body's needs, but also prevent electrolyte imbalance.

2. Drink more water and less in quantity. Many people are used to deciding whether they need to drink water based on whether they are thirsty or not. In fact, this is unscientific. Because thirst is an important signal that the body's water balance has been lost.

At work, if you are thirsty, you should not drink all at once. You should drink in several portions and in small amounts to facilitate absorption by the body. A reasonable approach is to drink 100ml to 150ml of water each time, with an interval of half an hour.

3. Try to avoid drinking drinking water that is too cold. When working outdoors in summer, the body temperature is usually higher, and drinking large amounts of cold drinks can easily cause digestive system diseases. Experts suggest that outdoor workers should not drink drinks below 5 degrees Celsius, but drink light salt water around 10 degrees Celsius. Because this can not only achieve the purpose of cooling down and quenching thirst, but also does not harm the stomach and intestines, and can also replenish the salt needed by the human body in a timely manner.
