Gas poisoning is a great hidden danger to people's life and health. To this end, I have arranged measures to prevent gas poisoning for your reference.

Measures to prevent gas poisoning:

First, strengthen the publicity and education of workers. The project department publicizes the knowledge of preventing gas poisoning to workers through night classes for migrant workers, safety activities and publicity measures, so as to improve workers' self-prevention awareness and enhance their self-protection ability.

Two, it is forbidden to use coal-fired gas-fired oil stoves for heating in the dormitory. Always keep the room well ventilated, especially in winter and rainy days.

Three, the project safety officer is responsible for organizing the implementation of cleaning the dining room and bathroom stoves once a week to ensure smooth exhaust of the stoves, and pay attention to check whether the rubber hose connected with gas appliance is loose, aging, damaged, bitten by insects and whether the switch is abnormal. At the same time, the project department will assign special personnel to manage the stoves, which should be placed on nonflammable materials, and flammable materials should not be placed around them to ensure the cleanliness and storage safety around the stoves.

Four, where there is fog and other low-pressure weather, each room should ensure indoor ventilation, and pay attention to the fire at any time.

5. Don't sleep in the car with closed doors and windows and air conditioning on, so as to avoid a large amount of carbon monoxide gas invading the car and causing poisoning.

Emergency measures for gas poisoning

Move the patient to fresh air quickly, rest in bed, keep warm and keep the respiratory tract unobstructed.

1 Correct hypoxia and quickly correct hypoxia. Inhalation of oxygen will accelerate the dissociation of carbon monoxide. Increase the emission of carbon monoxide. When fresh air is inhaled, it takes about 4 hours for carbon monoxide to be released from it. When inhaling pure oxygen, it can be shortened to 30 ~ 40 minutes, and inhaling pure oxygen at 3 atmospheres can be shortened to 20 minutes. Hyperbaric oxygen chamber treatment can increase dissolved oxygen in blood, improve arterial oxygen partial pressure, make oxygen in capillaries easily diffuse into cells, and can quickly correct tissue hypoxia. When breathing stops, artificial respiration should be carried out as soon as possible, or breathing should be maintained with a ventilator. Plasma exchange can be considered in critically ill patients.

2. After prevention and treatment of severe brain edema poisoning, brain edema can reach its peak within 24 ~ 48h. Dehydration therapy is very important. At present, the most commonly used is 20% mannitol, and intravenous drip is very fast. After 2 ~ 3 days, the phenomenon of increased intracranial pressure improved and can be alleviated. Furosemide can also be dehydrated by injection. Adrenal glucocorticoids such as adenosine triphosphate and dexamethasone are also helpful to relieve brain edema. If you have frequent convulsions, diazepam is the first choice at present, and then phenytoin sodium is dripped intravenously after convulsions stop.

To treat infection and control high fever, throat swab, blood and urine culture should be done and broad-spectrum antibiotics should be used. High fever can affect brain function. Physical cooling methods can be used, such as using an ice cap on the head and an ice pack on the body surface to keep the body temperature at about 32℃. If there is chills or difficulty in lowering body temperature during the cooling process, hibernation drugs can be used.

Promote the metabolism of brain cells by applying energy mixture. Commonly used drugs include adenosine triphosphate, coenzyme A, cytochrome C and a lot of vitamin C.

Prevention and care of complications and sequelae during coma is very important. Keep the respiratory tract unobstructed and perform tracheotomy if necessary. Turn over regularly to prevent pressure ulcers and pneumonia. Pay attention to nutrition and nasal feeding when necessary. Patients with acute CO poisoning should rest and observe for 2 weeks as much as possible after waking from coma to prevent the occurrence of nervous system and cardiac sequelae. If there are sequelae, give corresponding treatment.
