"Ride my beloved motorcycle, it will never be stuck in traffic~" electric bicycles save time and effort, and have been loved by the masses in recent years, but it also hides a lot of fire safety hazards

There are four words to describe the danger of e-bike fire
That is: fast, hot, poisonous, explosive
"Fast" means that the burning speed is fast
"Heat" refers to the high temperature produced when burned
"Poison" refers to the fact that a large amount of toxic gas is easily produced during combustion
"Fried" refers to the explosion of the battery of the electric bicycle after burning and heat
The danger of e-bikes burning in the hallway increases exponentially
Because the body, fence and cushion of electric bicycles are generally made of polymer combustible materials, the temperature can reach 200 degrees Celsius 90 seconds after the fire, and the electric bicycle begins to explode after 120 seconds, and the smoke will envelop the entire corridor, releasing a large amount of toxic smoke and spreading rapidly, which will cause poisoning and suffocation in a short period of time
In addition, the electric bicycle fire in the corridor may also ignite the piles of debris or meter boxes, etc., the actual flame temperature and smoke concentration is much higher than the experiment, the electric bicycle fire will also produce a large amount of hydrogen sulfide, carbon monoxide and other toxic gases, which will cause people to have nausea, lethargy, delirium, etc., if people evacuate from the corridor at this time, the degree of danger can be imagined

01. The charging time is too long, and the charging time of electric bicycles generally has a time limit, and the charging time of electric bicycles is too long, which can easily cause the charger to overheat, and the battery will heat up and swell, etc., and some people will charge for a long time all night, even more than 10 hours, which is very easy to cause fire
02 Outdoor flying wire charging: electric bicycles are privately connected to the wires outdoors for charging, and the exposed wires are easy to leak after exposure to the sun and rain, causing fires, if the wires are aging or there is a problem with the battery of the electric bicycle itself, it is more likely to cause fires
03. Illegal indoor charging: Some people park electric vehicles or charge electric bicycles in public areas such as shared walkways, stairwells, and safety exits in the building
04. Use inferior chargers, low-price, and poor-quality chargers, which only have a cooling fan and a heat dissipation plate inside, and no protection plates, which cannot play the role of self-protection and self-power-off
05. Illegal modification of electric bicycles: Some owners modify the power supply of electric bicycles without authorization, destroy the safety performance of the electrical circuits of the whole vehicle, and it is easy to cause overload, short circuit and other faults in the vehicle line when charging, and the probability of fire accidents is relatively increased

01Please do not purchase substandard products
When buying an electric bicycle, you must choose a regular and qualified electric bicycle and accessories. Try to avoid the increase in safety hazards and fire risks caused by unqualified products.
02Charging in the house is prohibited
It is strictly forbidden to park or charge e-bikes in public foyers, evacuation routes, stairwells, safety exits, and other areas. Do not bring the battery back indoors to recharge.
03Charge in the designated area
Electric bicycles should be charged in the centralized charging area set up by the school, and "flying wire" charging is prohibited.
04Pay attention to the charging time
According to the different battery capacity, the general electric bicycle can be fully charged in 8-10 hours. Charging is best done during the day, supervised.
05Keep away from flammable and explosive materials
When charging electric vehicles, it is necessary to stay away from flammable and explosive materials to prevent the electric bicycle from igniting nearby items when it catches fire, causing greater danger.
06Do not modify electric vehicles without permission
Do not modify the battery, install audio, lighting and other non-original facilities without authorization, and strengthen daily self-inspection and self-inspection to ensure that the vehicle is in good condition.
Fire safety is as important as a mountain, and prevention is not "burning" to keep safe. Safety knowledge should be kept in mind, and compliance with the norms should not be careless. While standardizing the use of electric bicycles, please be sure to abide by fire safety regulations, strengthen home fire prevention, improve fire prevention awareness, and improve your own protection ability; be familiar with the surrounding environment of the residence, learn fire escape, emergency avoidance and self-rescue skills, do a good job of cleaning the kitchen, clear the balcony, clear the walkway, and do a good job of turning off the fire, electricity, and gas before the end of use or leaving home, and do not store flammable and explosive dangerous goods at home; pay attention to electricity safety, correct use of gas, strengthen children's safety education, and at the same time unblock the corridor, Passages, balconies and safety exits and other firefighting life passages, so as not to affect the passage of firefighting vehicles and delay the best time for fire fighting.
Thank you for seeing the end
