Freshman summer safety blackboard content

The scorching sun in summer, high temperature and high humidity weather can easily lead to various production safety accidents. High temperature heatstroke can cause body temperature rise, dehydration, fainting and even death; Food poisoning can cause dizziness, vomiting, abdominal pain and even death; The "electric tiger" is more harmful, especially the rainy and humid weather will increase the chance of electric shock and threaten life safety; Fire accidents and "forbidden zone accidents" occur frequently in summer, which can easily lead to group deaths and injuries. Huaian police reminded the masses to master the necessary safety knowledge and stay away from injury accidents.

First, heatstroke prevention and first aid

In order to prevent heatstroke, measures such as ventilation, heat insulation, lounge and short-term rotation should be taken. Workers working in high temperature should drink more cool drinks and physiological saline, prepare Ren Dan and Huoxiang Zhengqi water, and equip them with corresponding protective articles such as heat protection clothes, heat-insulating masks, gloves and hats.

Patients with heatstroke should be moved to a ventilated, cool and dry place to lie on their backs, and cold compress or wipe with cold wet towels and ice packs; Conscious patients can drink mung bean soup, light salt water, Ren Dan or Huoxiang Zhengqi water; Severe patients should be sent to hospital in time for emergency treatment.

Second, food hygiene and safety knowledge

First, pay attention to personal hygiene, eat fresh food that meets hygiene standards, and don't eat cooked food that is cold or left for too long. The second is to eat more fruits and vegetables. Summer is the peak season for melons and vegetables. You can eat more cold vegetables such as cucumber, loofah, pumpkin, bitter gourd and watermelon. The most important factor affecting human body in summer is the poison of summer dampness. Eating some cool vegetables is conducive to promoting fluid production and quenching thirst, relieving summer heat, clearing away heat and purging fire, expelling toxin and relaxing bowels. The third is to eat more "sterilized" vegetables. The high temperature in summer and the rapid spread of pathogenic bacteria are frequent seasons for human diseases, especially intestinal infectious diseases. At this time, eating more "sterilized" vegetables can prevent diseases. This kind of vegetables include: garlic, onion, green onion, garlic sprout, etc. , rich in broad-spectrum fungicides; It can kill and inhibit various pathogenic bacteria.

Third, beware of power safety accidents.

When it is wet in summer, the insulation material will lose its insulation performance when it is wet, which makes people sweat easily and increases the chance of electric shock. Electrical equipment should have grounding and zero protection, install leakage protection devices, and the workplace must be kept dry and clean. Cut off the power supply of maintenance equipment, put up a warning sign "No closing, someone is working", and lock the power supply when possible. When moving electrical equipment, first cut off the power supply and protect the wires. Insulation aging, short circuit, overload, loose joints, dust accumulation, humidity, and electrical appliances close to flammable materials are all likely to cause fires. Electricians must receive special training and hold relevant certificates. Operators must wear insulating protective articles, and personnel engaged in high-voltage live working should wear shielding clothing. Dry powder and carbon dioxide fire extinguisher should be used when electrical equipment is on fire.

Fourth, prevent injuries in the restricted area.

Pits, tanks, basements, underground pipelines and other restricted areas may have toxic gases such as hydrogen sulfide or oxygen deficiency hazards, which are prone to fatal accidents. Therefore, preventive measures should be taken before entering the "forbidden zone", and the safety factor should be determined by acid-base liquid test and candle fire test. Once you feel dizzy during entry, you should exit immediately. When an accident occurs in the restricted area, blindly entering the restricted area to save people will lead to many deaths and injuries. Professionals should be informed and effective protective equipment should be worn before entering the rescue.

Five, pay attention to fire safety hazards

In public places where people are concentrated, the evacuation passage of safety exits must be kept clear. Flammable, explosive, flammable, explosive or dangerous chemicals that react easily when wet cannot be stored in the open air. Fireworks are strictly prohibited near places where flammable and combustible materials are stored. Safety precautions must be taken when it is necessary to carry out operations that produce open flames in places prone to fire. Units that produce flammable and explosive chemicals shall indicate the precautions for fire prevention and explosion prevention on their products. Strengthen the safety knowledge education of inflammable and explosive dangerous chemicals to prevent fire accidents caused by improper use.
