The underground garage is a project with higher technical requirements and more complex processes. Making full use of the underground space to build a parking lot has achieved the purpose of diverting people and vehicles. Effectively solve the community parking difficulties, enhance the happiness of residents, in order to achieve the comprehensive utilization of underground space and resource sharing.

With the increase of residents, there is a shortage of parking Spaces on the ground, and underground garages provide convenience to residents, but there are also safety risks. Underground garages will produce harmful carbon monoxide toxic gases, seriously endangering the health of residents. To eliminate all problems and risks in the bud, it is necessary to build an early warning and monitoring system.

Causes of toxic and harmful gases

The main reason is that cars emit exhaust gas

The underground parking lot is a closed environment, and the exhaust gas produced by the car is not easy to discharge, resulting in a choking smell in the parking lot. It is due to insufficient gasoline combustion that the exhaust gas containing a large amount of CO will be produced, which is harmful to health. It can be detected with toxic and harmful gas detectors.

The harm of poisonous and harmful gases

The underground garage ventilation is not good, resulting in poor air quality, carbon monoxide gas, short exposure to carbon monoxide, there will be headaches, dizziness, insomnia, weakness and other symptoms, long-term exposure to carbon monoxide, will cause chronic poisoning, serious will endanger life.

Toxic and harmful gas solutions

Toxic and harmful gas detectors are set in the underground garage, and combustible gas alarm system is connected to set alarm limits according to regulations; When the gas concentration reaches the lowest extreme alarm limit, start the sound and light alarm, and start the exhaust equipment, when the gas concentration reaches the high alarm value, start the emergency cut off valve equipment.

Instrument for detecting harmful gases

For the environmental monitoring of underground garages, the main use of toxic and harmful gas detection equipment, temperature and humidity detection.

Installation precautions

1. Gas detector can not be used in explosion-proof requirements.

2. Do not install the gas detector in a position that can generate high heat.

3. Do not install the gas detector in a place that vibrates. Frequent vibration may damage the sensor of the alarm.

4. The gas detector can not be installed in the vents, ventilation fans, doors and other places with large air flow.

5. If the house needs to be painted or welded, install the alarm device after the paint is dried and welding is completed.

6. The communication bus of the alarm and the AC signal cable must not be installed in the same pipe.
