Industry Background:

    Rail/public transportation is a city's infrastructure, an essential tool for people's production and life, and a bridge that connects people. With the rapid development of society and the acceleration of urbanization, urban areas and towns are highly densely populated, resulting in long-term overloading of urban public transportation, especially during rush hours in the main urban area. , "squeeze"buses and subways have been considered A normal phenomenon in social life, passenger density sometimes even reaches per square meter6～8people. Due to the crowding of high-density people on buses and subways, if there is an emergency such as a fire, the road traffic will be almost paralyzed. In addition, as new energy vehicles are widely used as buses, new safety accidents such as spontaneous combustion caused by power supply and explosion caused by natural gas are gradually emerging. Cause mass death and mass injury, great harm to society. At the same time, the operating speed of high-speed rail has been continuously improved, the number of routes has increased, and the demand has increased day by day. Rail freight, high-speed rail, and EMUs have developed rapidly. If a fire or other accident occurs on the high-speed rail, it may cause heavy casualties and extremely serious adverse effects such as the scrapping of trains and tracks.

    Industry Fire Characteristics:

1. There are many flammable materials in vehicles, which are prone to produce toxic gases;

2. Passengers are crowded and evacuation is difficult;

3. Early fire alarms are not easy to detect;

4. There are many electrical facilities and there are dynamic fire hazards;

5. Once a fire occurs, the social impact will be far-reaching.

    Industry Applicability:

    Whether it is a rail transit or a bus, the driver's cab, power distribution cabinet, passenger and cargo compartment, etc. are all relatively closed environments. Combined with the advantages of perfluorohexanone fire extinguishing agent being clean, environmentally friendly, and almost harmless to human body, perfluorohexanone fire extinguishing agent is very suitable for various places of rail transit and public transportation.

    Relevant achievements of the company in this field:

    The perfluorohexanone fire extinguishing system developed by our companyapplied in the bus cabin uses perfluorohexanone fire extinguishing agent (model: span>TKD-8341) as a fire extinguishing medium, in addition to fire extinguishing agent, the system is mainly composed of fire extinguishing device, fire extinguishing controller, sprinkler, pipeline and other parts. The system can be started with one key. Compared with traditional dry powder, water-based and other commonly used fire extinguishing equipment on buses, the operation is simpler and faster, the floor space is smaller, and the weight is lighter, which can effectively extinguish the initial stage of the cabin. Fire, it only takes a few seconds from the discovery of the fire to the extinguishment, which has won precious time for passengers to escape and evacuate, and minimized casualties and property losses. At present, the company's research and development“R&D and application of key technical equipment for emergency safety assurance of passenger vehicles”project Won 2019year“China Occupational Safety and Health Association Science and Technology” span>Second prize for individuals and units, the company also, as always, makes a reserve for technological innovation in rail transit and public transportation safety, and practices corporate social responsibility.
