Matters needing attention in winter heating

Coal fire heating must prevent gas poisoning. As soon as the heating season enters every year, the invisible killer of carbon monoxide will lurk around people. In winter, the outdoor temperature is low, people like to close doors and windows, and the air circulation is an important factor causing carbon monoxide poisoning. Therefore, we must take preventive measures when heating in winter.

Matters needing attention

1, pay attention to ventilation

When using heating equipment such as coal stoves and charcoal fires indoors, the coal should be burned out and not covered; Doors and windows should not be completely sealed with plastic film, but a certain gap should be reserved to make indoor air circulate and avoid the accumulation of carbon monoxide. Ventilate the doors and windows frequently to keep the indoor air fresh.

2. Choose a good stove

Chimneys should be installed in coal stoves for heating, and stoves should be purchased from formal channels. The joint of the chimney should be firmly connected (the thick end of the chimney faces the coal stove), and the chimney structure should be kept tight and well ventilated to prevent the leakage and backflow of flue gas and keep it smooth. It is best to open the chimney mouth in the downwind direction, and the chimney extending out of the window should be equipped with a wind cap, the opening should be lower than the eaves, and the chimney exit should be upward, at least not facing north or west.

Step 3 check regularly

Correct installation and use of coal stoves, charcoal fires and other heating equipment, regular inspection of stoves, maintenance and cleaning of chimneys and air buckets, preferably once every two months, to maintain smooth flow. At this time, a lot of coal ash accumulated in the chimney, which is the easiest to block the flue; Chimney joints should be checked frequently and sealed with adhesive tape to prevent air leakage. It is best not to put a coal stove without a chimney indoors. Pay attention to open the doors and windows for ventilation during the day to ensure adequate air circulation and oxygen content in the house. Gas is lighter than air and always floats above the room. Therefore, as long as a fan bucket is installed at the top of the window, leaving a passage for gas to escape, cold air cannot enter, and the chance of gas poisoning will be greatly reduced.

Step 4 stay away from the bedroom

Heating equipment such as coal stoves and charcoal fires should be far away from flammable, explosive and volatile toxic substances and should not be placed directly in the bedroom; If conditions permit, it is best to move the stove outside before going to bed at night.

Step 5 choose carefully

Try not to use heating equipment such as coal stoves and charcoal fires under meteorological conditions such as rain, snow and hail with low air pressure and high relative humidity; When eating hot pot at home, it is best not to use coal or charcoal hot pot. If used, it is best to put it in a ventilated hall or keep the doors and windows open and ventilated in time.

Step 6 install the detector

Units or families using coal stoves should install carbon monoxide detectors, and check and maintain them regularly to ensure the normal operation of the detectors.

poisoning symptom

1. In case of dizziness, headache, general weakness, unresponsiveness, nausea, vomiting and other symptoms. You should consider carbon monoxide poisoning and seek medical attention immediately. If you are seriously poisoned, you will lose consciousness and twitch. If not rescued in time, it will be fatal.

People with mild poisoning will get better if they rest in fresh air for 2-3 hours. However, moderate and severe patients should be sent to the hospital with hyperbaric oxygen chamber as soon as possible after on-site first aid to prevent serious complications and sequelae.

Emergency treatment principle

Get out of the toxic environment quickly

Quickly move the patient from the poisoning site to a place with fresh air and good ventilation.

Untie the collar button and belt of the poisoned person, keep the respiratory tract unobstructed, lie on your side, keep the respiratory tract unobstructed, and prevent the vomit from choking. At the same time, we should pay attention to keep warm to prevent complications.

Patients should keep quiet and rest, avoid aggravating oxygen-consuming activities, and let patients take oxygen as soon as possible.

Call 120 as soon as possible and send it to the hospital for emergency treatment.
