Carbon monoxide poisoning is caused by the incomplete combustion of carbon-containing substances and the gases that enter the respiratory tract. Carbon monoxide has a very high binding affinity with hemoglobin, and it is very easy to form carboxyhemoglobin, which causes hemoglobin to lose its oxygen-carrying ability and function. The main clinical manifestation is hypoxia, which causes tissue asphyxiation. Mentality of mild poisoning: sudden headache, dizziness, nausea, fatigue or confusion, which is more likely when multiple people have similar symptoms at the same time.
1.Carbon monoxide (CO) must be judgmed with professional testing equipment:
(1).Install a fixed carbon monoxide leak alarm
Fixed carbon monoxide leak alarms are divided into fixed CO detectors and CO gas controllers. The detector is installed in places where CO may leak, and the gas controller is installed in the monitoring room to monitor the concentration values of all detectors connected to the controller and alarm.
(2).Use portable CO gas detector
The portable gas detector uses advanced sensor technology to quickly detect the gas composition and concentration in the environment, and obtain accurate data in a short time. It is small in size and light in weight, and is easy to carry to any place where detection is required, which is very suitable for on-site detection.
2.Which places need to prevent CO poisoning?
(1).Home environment:
Gas water heater installation location: Gas water heaters may produce carbon monoxide during use, especially in poorly ventilated spaces such as bathrooms. Carbon monoxide is easy to accumulate and cause harm to the human body.
Coal stove heating room: In some rural areas or old communities, when using coal stoves for heating, a large amount of carbon monoxide will be produced when the coal is not completely burned. If the room is well sealed and poorly ventilated, the carbon monoxide concentration is easy to increase, causing poisoning accidents. Therefore, it is very necessary to install a carbon monoxide detector in rooms that use coal stoves for heating.
(2).Industrial and high-risk workplaces:
Metallurgical and chemical enterprises: Carbon monoxide may be produced during the production process. For example, incomplete combustion of coal in the process of iron and steelmaking will produce carbon monoxide; certain chemical reactions in chemical enterprises may also release carbon monoxide. These enterprises should install carbon monoxide detectors in production workshops, warehouses and other areas to prevent carbon monoxide leaks from causing safety accidents.
Mine: There are flammable and explosive gases such as gas in mines, and they may also contain carbon monoxide. Carbon monoxide not only threatens the life safety of miners, but may also cause accidents such as explosions. Therefore, mines must install carbon monoxide detectors to strengthen the monitoring of harmful gases such as carbon monoxide.
Hazardous goods storage and transportation and oil and gas industry: Oil and gas pipelines, oil storage tank areas, refineries, etc. need to detect carbon monoxide and flammable and explosive gases to ensure storage and transportation safety.
3.Commercial and public confined spaces
Hotels and guesthouses: The rooms in hotels and guesthouses are usually relatively closed, and gas equipment or central air conditioning may be used. If the equipment fails or the ventilation system is poor, carbon monoxide may accumulate. In order to protect the lives of guests, hotels and guesthouses should install carbon monoxide detectors in guest rooms, boiler rooms and other areas.
Restaurants and hot pot restaurants: These places usually use gas stoves or charcoal grills, which may produce carbon monoxide during use. Especially in the case of poor ventilation, the carbon monoxide concentration is easy to exceed the standard. Therefore, these places should install carbon monoxide detectors to ensure the safety of customers and employees.
Underground parking lot: There is carbon monoxide in the exhaust gas of cars in the underground parking lot. If the ventilation system is not good, carbon monoxide will accumulate in the parking lot. Long-term exposure to high-concentration carbon monoxide environments is harmful to the health of parking lot managers and people entering and leaving vehicles. Therefore, underground parking lots should be equipped with carbon monoxide detectors.
Laboratories and sewage treatment plants: Chemical laboratories need to monitor experimental gas leaks, and sewage treatment plants need to prevent poisoning caused by the combination of hydrogen sulfide and carbon monoxide.
