Are your escalator brushes flame-retardant? _common problem

Believe it, seeing 'the escalator in the downtown supermarket catches fire and many people are trapped'Injured' news headlines are not surprising to everyone, not because they are the headline party, but because they appear so frequently that everyone is accustomed to it. However, these accidents happen on our side, and we must pay attention to it to ensure our own travel safety. The spontaneous combustion of the escalator is nothing more than two reasons. One is the failure of the elevator itself; the other is caused by external factors. Let's first analyze the cause of the elevator's own failure. Experts said: Although there are not many circuits in the escalator, the escalator is always in operation, and there is a possibility of spontaneous combustion after heating! Escalators, like elevators, need to be maintained every 15 days. However, in reality, due to operating costs and competitive pressures, there are countless escalator maintenance companies. Even the escalators of some major brands cannot be fully maintained. In order to survive, some bad companies will start to fight a price war, and once the maintenance price is lower than their operating cost, these escalator maintenance companies will cut corners or walk through the scene, and the quality of elevator maintenance will be greatly reduced. Escalators are metal parts and cannot be operated without lubricating oil. If the elevator is not properly maintained, or the wiring is aging, and the wires are exposed, sparks and spontaneous combustion may occur. At this time, the use of flame-retardant escalator brushes can greatly reduce the risk of spontaneous combustion of the escalator. Secondly, external factors will ignite the brushes on the escalator due to unextinguished cigarette butts discarded by passengers on the escalator, causing smoke to occur, and even then, finally causing panic among the masses. Therefore, in order to protect the personal safety of other passengers and yourself when riding on an escalator, we do not smoke cigarettes in public.

We have all noticed that there are two brushes on both sides of the escalator, and these two brushes are often the main cause of burning. Do you know the standard of flame retardant escalator brush? Can be tested according to the following reference time. HB: It is the low flame retardant grade in the UL94 standard. It is required that for samples with a thickness of 3 to 13 mm, the burning rate is less than 40 mm per minute; for samples with a thickness of less than 3 mm, the burning rate is less than 70 mm per minute, or extinguished before the 100 mm mark. V-2: After the sample is subjected to two 10-second burning tests, the flame is extinguished within 60 seconds. There may be burning objects falling off. V-1: After two 10-second burning tests are performed on the sample, the flame goes out within 60 seconds. No burning objects should fall. V-0: After the sample is subjected to two 10-second burning tests, the flame is extinguished within 30 seconds. No burning objects should fall. The international standard flame retardant level is UL94-V0 level. The flame retardant grade is gradually increased from HB, V-2, V-1 to V-0. If an escalator company chooses a brush with flame retardant function when purchasing an escalator brush, it will be able to ensure the safety of passengers to a greater extent. In public places, there are a lot of people, and we can control the accident at the source, so why not do it. It is a good choice to install a flame-retardant escalator brush on the escalator!
