Background:
Carbon monoxide is one of the most common colorless, odorless, odorless, tasteless and non-irritating harmful gases, which can be detected by CO gas detector.
When gas burns, if the oxygen in the air is insufficient and combustion is insufficient, carbon monoxide poisoning, commonly known as gas poisoning, will occur.
Carbon monoxide inhalation can cause poisoning in poorly ventilated environments such as homes and workplaces.
The use of gas hot water heater, gas stove for too long, closed doors and Windows poor ventilation, insufficient air, insufficient gas combustion, indoor carbon monoxide concentration, resulting in poisoning accidents.
There are three levels of carbon monoxide poisoning:
1,Mild poisoning: there will be headache, dizziness, palpitation, nausea, vomiting and limb weakness and other symptoms;
2,Moderate poisoning: patients with chest tightness, shortness of breath, difficulty in inhaling, blurred vision;
3,Severe poisoning: coma, dyspnea, arrhythmia or heart failure occurs rapidly, resulting in death if medical attention is not available.
Non-occupational carbon monoxide poisoning generally refers to the occurrence of carbon monoxide poisoning in the daily life of the public, which is different from the occurrence of occupational carbon monoxide poisoning in production sites.
So how can you avoid this in your life?
Which places are prone to non-occupational carbon monoxide poisoning:
family
According to the statistics of national monitoring data in recent five years, non-occupational carbon monoxide poisoning mainly occurred in families, accounting for about 95.8% of all non-occupational carbon monoxide poisoning incidents. Key risk factors include:
1, in the poorly ventilated environment, the use of coal stove, charcoal fire, earth kang, firewall and other heating methods.
2, gas, gas water heater use, improper installation or unqualified quality.
3, gas stove or gas pipeline gas leakage.
Other places
Other major risk factors for non-occupational carbon monoxide poisoning include:
Improper use, installation or maintenance of heating stoves, gas and gas equipment and ventilation devices in catering service units such as collective canteens, restaurants and hotels.
Small oil and steam generators are used in small closed garage or underground room.
3, vehicle exhaust emissions, in a closed air-conditioned vehicle for a long time, etc.
Periods and areas of high incidence of poisoning:
Non-occupational carbon monoxide has an obvious seasonal high incidence. The season of high incidence of poisoning is winter and spring, from November to March of the next year is the month of high incidence of incidents, from December to January of the next year, the peak, obviously decreased in April of the next year, only sporadic cases occurred from May to October. The seasonal distribution characteristics are basically consistent with winter and spring heating season in north China.
The high incidence of non-occupational carbon monoxide poisoning is mainly distributed in northeast, North, central and east China.
How to prevent carbon monoxide poisoning:
1,Coal stove, charcoal fire and other heating equipment:
Choose central heating if possible during the cold season.
Indoor use of coal stove, charcoal and other heating equipment, coal to burn, do not cover; Should often door window ventilated take a breath, maintain indoor air fresh.
The coal stove should be installed with a chimney, and the interface of the chimney should be firmly connected with the stubble (the thick end of the chimney is towards the coal stove) to prevent air leakage; Chimney mouth is best to open downwind, out of the outdoor chimney, it is best to install a windscreen or neck, to prevent the wind will blow gas back to the house; Be sure to install air ducts in the house, preferably above the doors and Windows.
Correct installation and use of coal stove, charcoal fire and other heating equipment, regular inspection of stoves, maintenance and cleaning chimney, ventilator, keep chimney, ventilator unblocked.
Coal stove, charcoal and other heating equipment should be away from flammable, explosive, volatile toxic substances, not directly in the bedroom; If conditions allow, it is best to move the stove outside before going to bed in the evening.
In low pressure, relative humidity of rain, snow and hail weather and other meteorological conditions, try not to use coal stove, charcoal fire and other heating equipment; When eating hot pot at home, it is best not to use coal, charcoal pot, if used, it is best to put in the ventilated hall or keep the doors and Windows timely open ventilation.
When the home uses coal stove, charcoal fire and other heating equipment, it is best to install CO gas detector, and regular inspection and maintenance, to ensure the normal operation of the detector.
2, gas, gas water heater
When buying water heater of gas, gas, need to choose normal manufacturer to produce, qualified water heater; It must be installed by professional personnel and can be used after passing the test.
When water heater of use gas, gas, want to maintain good ventilated condition, wash bath time is not too long, use should check water heater to close completely.
Reduce pressure valve to water heater of gas, gas regularly and leather tube undertake maintenance, if discover to have damage, rust, leak when the problem such as air should be changed in time.
When using gas and gas water heater in the home, it is best to install CO gas detector, and check and maintain regularly to ensure normal operation of the detector.
3, gas, gas cooker and pipeline
When buying gas, gas stove is provided, the water heater with qualified quality that needs to choose normal manufacturer to produce; It must be installed by professional personnel and can be used after passing the test. Do not change the gas and gas pipeline facilities without permission.
When using gas and gas cooking utensils, remember that people should not stay away from them. Strictly prevent the overflow pot from pouring out the cooking fire, resulting in the overflow of gas and gas. Check whether the cooking utensils are completely closed after use.
The gas tank, pressure reducing valve, leather hose and gas and gas pipeline of gas and gas stove are repaired regularly. If the problem such as aging, damage, rust, leakage, or lax closure is found, it should be replaced and maintained in time.
When using gas and gas cookers at home, it is best to install CO gas detectors and check and maintain them regularly to ensure the normal operation of the detectors.
4, small oil and steam generators
Do not use small oil and steam generators indoors, in garages, basements and other places. Use them outdoors and keep them away from doors and Windows, ventilation and exhaust devices.
Add carbon monoxide (CO) sensors to small oil and gas generators to detect buildup of potentially deadly gas CO. CO sensors detect and track carbon monoxide – can shut down the machine in an emergency to avoid carbon monoxide poisoning.
5,The car
When the car is parked in the garage, basement, do not let the car engine continue to run; When the car is stopped, do not leave the air conditioner on for a long time. Do not sleep in the car with the Windows and doors closed and the air conditioner on.
Check your car’s exhaust system regularly to prevent carbon monoxide leaks from the exhaust system.
Product Introduction:
If you want to prevent carbon monoxide poisoning, it is advisable to install a CO gas detector.
CO gas detector is specially used to detect carbon monoxide concentration in the air equipment, can timely alarm when carbon monoxide concentration exceeds the standard, through the linkage device can also timely open the window or exhaust fan for ventilation, so that people away from the damage of carbon monoxide.
In addition, carbon monoxide sensor is one of the core components of carbon monoxide detector, so it is very important to choose a carbon monoxide gas sensor with good repeatability and stability.
