Emergency plan for laboratory accident treatment

In order to prevent and reduce the occurrence of sudden emergency safety accidents, improve the laboratory emergency management mechanism and deal with possible accidents, protect the personal safety of teachers
and students and laboratory property safety, and ensure the smooth progress of teaching and research work, this plan is formulated in combination with the actual situation of our school.

When an accident occurs, the party concerned, the experimenter and the head teacher are the "first responsible person" for rescuing the scene of the accident. Under the condition of ensuring their own safety, they should
take corresponding measures to deal with and rescue the accident, and report to the safety department and school leaders' parents in time. In case of any serious situation, it is necessary to rescue actively and ask for help
from fire 119 and emergency 120 in time. When reporting, the unit, location, accident situation, personal injury, etc. shall be explained, and personnel shall be sent to wait for rescue personnel and vehicles at the appointed
place.

1、 First aid for electric shock

In case of electric shock, cut off the power supply immediately or try to make the person get rid of the power supply; when the patient stops breathing or cardiac arrest, artificial respiration or cardiac massage should be
carried out immediately. Pay special attention to the phenomenon of suspended animation, do not give up rescue, as soon as possible sent to the hospital for treatment.

2、 Fire treatment

1. When there is a fire in the laboratory, the cause of the fire should be analyzed immediately and all systems in the experimental process should be separated.

2. When the sample is heated or there is a fire in a small range during the experiment, wet stone should be used immediately

Put out the open fire with cotton cloth or wet cloth, pull out the power plug and turn off the main switch. When flammable liquid or solid (mostly organic matter) is on fire, water must not be poured. A wider range of fire
should be extinguished immediately with fire sand, foam extinguisher or dry powder extinguisher. Carbon tetrachloride fire extinguisher should be used when precision instruments are on fire. Fire in laboratory should not
be put out with water.

3. When the personnel's clothes are on fire, cover the person on fire with blankets and other articles immediately, or use water to extinguish the fire if necessary. However, it is not suitable to run in a hurry, so as to avoid
the airflow flowing to the burning clothes, and then increase the flame.

3、 First aid for burns

1. For ordinary mild burns, cool emulsion can be applied to the wound and bandaged; slightly severe burns can be sent to the hospital for treatment according to the burn situation; in case of shock, the wounded should
be immediately informed to come to the hospital for treatment.

2. In case of chemical burns, the clothes should be removed quickly, the chemicals remaining on the skin should be removed first, and then washed with water for many times. At the same time, depending on the burn
situation, the patients should be sent to the hospital for treatment or informed to come to the hospital for treatment.

3. In case of any injury to the eyes, an ophthalmologist should be consulted immediately for diagnosis. However, in the case of chemical burns, every second should be taken. Before the doctor arrives, he should
immediately flush the eyes with distilled water. When washing, the eyes should be washed with thin water, and the eyes should not be directly exposed.

4、 First aid for trauma

1. Small trauma can be cleaned with disinfection forceps or gauze, and 3.5% iodine wine is applied around the wound and wrapped. If there is more bleeding, the compression method can be used to stop bleeding. At the
same time, the wound should be treated well, and the medicine such as hemostasis and anti-inflammatory powder should be put on tightly.

2. In case of large trauma, arteriovenous bleeding, or even fracture, first-aid bandage should be used immediately to tie the bleeding part of the wound to stop bleeding. The wound should be covered with sterilegauze and
sent to the clinic or hospital for treatment immediately. But when the hemostasis time is long, we should pay attention to relax once every 1-2 hours to avoid limb ischemia and necrosis.

5、 First aid for poisoning

The first aid for poisoning patients is mainly to remove the patients from the area of toxic substances as soon as possible before the patients are sent to the hospital or doctors arrive, and try to find out the toxic substances,
so as to assist the doctors to eliminate the poisons in the poisoning patients. In case of respiratory arrest and cardiac arrest, artificial respiration and cardiac massage should be performed immediately until the doctor arrives
or is sent to the hospital.

6、 Environmental pollution

1. The emergency team shall cooperate with relevant departments to quickly control the source of the accident, and take measures to close, isolate and disinfect the actual and possible hazards caused by theaccident to
human body, animals and plants, soil, water source and air, so as to reduce the injury to personnel and environmental pollution as much as possible.

2. Assign special personnel to call the police or ask for rescue to the relevant departments such as public security fire control, environmental protection, power supply and water supply, sanitation and epidemic prevention,
organize personnel evacuation and site protection, and guide relevant personnel of public security fire control, environmental protection, safety supervision, power supply, water supply, sanitation and epidemic prevention
departments to enter the scene for rescue.

3. In case of waste gas leakage, timely and effectively evacuate personnel, open doors and windows and ventilation devices. If a large amount of toxic gas leaks, it is necessary to inform the surrounding residentsand unit
personnel to evacuate immediately and ask the relevant departments for support.

4. According to the nature of the toxic liquid, the corresponding first aid measures should be taken immediately to control the leakage and deal with the waste liquid. When a large amount of toxic waste water and waste
water are leaked, the Department of water supply and environmental protection should be informed immediately.

5. In case of environmental pollution caused by solid waste, the pollutants should be monitored in time, the polluted area should be isolated and treatment measures should be taken.

6. After the poisoning accident caused by waste gas, waste liquid and solid waste, cover the mouth and nose with a wet towel immediately, transfer the poisoned person from the poisoning site to a ventilated andclean place,
and use first-aid methods such as artificial respiration and vomiting to help the poisoned person remove the poison in his body and send him to the medical staff for treatment. The concentration of toxicsubstances in the
environment can also be reduced or eliminated by means of ventilation and water dilution. If necessary, call 120 emergency call to protect the scene.
