Carbon monoxide as we know it is a colorless, odorless and toxic gas. With the improvement of people's living standards and the popularity of private vehicles, underground garages have become almost a daily rite of passage. The underground garage is a closed or semi-closed building, and the air circulation is naturally not smooth, and the environmental pollution of the underground garage is mainly from the automobile exhaust, and the main component of the automobile exhaust is carbon monoxide. The most significant effects are on hypoxia in human tissue, the heart and the brain. So the underground garage stay time should not be too long, otherwise the consequences are unimaginable.

The production of carbon monoxide in the underground parking lot mainly comes from the car engine, when the engine is running at idle, due to insufficient gasoline combustion, it will produce exhaust containing a lot of carbon monoxide. The underground car park is a closed environment, vehicles enter and exit more frequently, and the exhaust gas emitted is not easy to discharge, and it is easy to accumulate a large amount of carbon monoxide gas, resulting in a choking smell in the underground car park and damaging people's health. If you turn on the air conditioning outside the car at this time, because the external carbon monoxide will quickly enter the car with the exchange of air, and then cause carbon monoxide poisoning. Therefore, the underground parking lot should be equipped with a supply and exhaust system, replaced with fresh air, and should not be kept for a long time, replaced with fresh air, the CO content of the underground garage should be lower than 25ppm in the long term, and should not be higher than 37.5ppm in the short term.

Manifestations of carbon monoxide poisoning

In mild cases, carbon monoxide poisoning can cause headaches, weakness, dizziness, and difficulty breathing. Patients with cherry-red lips may have nausea, vomiting, confusion, collapse, or coma. In severe cases, it can be a deep coma, accompanied by high fever, increased muscle tone in the limbs, and paroxysmal or tonic spasms. Patients often have brain edema, pulmonary edema, myocardial damage, arrhythmia, and respiratory depression, which can lead to death.

How can underground garages prevent carbon monoxide poisoning

The most effective method for carbon monoxide (CO) toxic waste gas treatment is to install carbon monoxide toxic and harmful gas alarm, prevention, early warning control system (graphic monitoring system + alarm controller + carbon monoxide gas detector + linkage equipment), when the carbon monoxide gas in the environmental space reaches the early warning value set by the control system, the control system will be in the form of electrical signals, It is transmitted to the controller and linked to the on-site exhaust system to quickly discharge toxic and harmful gases, and regularly exhaust to ensure that the carbon monoxide concentration in the underground parking lot is lower than the hazardous level.

The system can detect the carbon monoxide concentration value in the underground garage environment in real time, and the concentration value of multiple fire protection zones can be centrally displayed and monitored. When there is a carbon monoxide gas leak in the air, the carbon monoxide gas detector will detect the gas concentration and transmit it to the control system. Once the concentration reaches the alarm value, the control system will issue an audible and visual alarm and output an alarm signal to start the smoke exhaust fan. The site monitoring security personnel can take effective measures in time to reduce the carbon monoxide gas concentration on site.

ASD5330C household toxic and harmful gas detector power supply and bus parts are non-polar design, anti-interference anti-static protection circuit; The mass of carbon monoxide is similar to the specific gravity of air, and the gas detector is installed at a height of 1.5 ~ 2.0m.

ASD5300C toxic and harmful gas detector can be used to constantly detect the concentration of related toxic gases in the petroleum, chemical and pharmaceutical fields to ensure the safety of workers. It converts the toxic gas concentration at the site into an electrical signal and transmits it to the monitoring equipment located in the safety zone to achieve the purpose of monitoring the toxic gas concentration at the site.

ASD5100 combustible gas alarm controller adopts 4-loop ABUS bus for data transmission, which has long transmission distance, strong anti-interference and large capacity memory function. The controller has a network communication 485 interface, which can realize the remote communication network with the control system in line with the communication protocol by extending the communication 485 module, and realize the remote display of alarm information.

In the journey of life, safety accompany me, from our birth, to toddler, to leave the mother's help, wobbly walking on the road of life, we have been relying on "safety" this crutch. Without it, we will fall down, may not finish the ups and downs, and it is impossible to reach the peak of life.

The installation of carbon monoxide gas alarm system in the underground garage is a guarantee for your safety, and it is also a necessary link in today's town construction. It can effectively resist the damage caused by waste gas to our human body and build a healthy living environment for us.
