What are the hazards of counterfeit firefighting products?

In recent years, during firefighting and training in the fire brigade, there have been frequent embarrassing scenes: when they laid water hoses and set up water guns to prepare them for fires, the fire trucks were just under pressure and the water hoses were “squeaky.” When they connected the suction hose to get water from the fire hydrant, they just put the fire wrench on it and screwed it, and the wrench sleeve cracked: When they rushed toward the target with the fire ladder, they turned and leaped. while on the rung "click" sound off ......

The scourge of fake and inferior firefighting products can be described as endless. According to statistics, in China in the past five years, an average of 230,000 fires have occurred every year. About 2,400 people are killed each year in the fire. The average annual direct economic loss caused by fires is about 1.4 billion. yuan. When the fire came, some fake and inferior fire-fighting products failed to do what they were supposed to do, which delayed the time for fire suppression, affected the effect of disaster relief, and increased losses.

The delay in extinguishing the fire has caused trouble

2005 June 10, Chaonan Shantou City, Guangdong Province in South China hotel fire. According to firefighters at the time of the fire fighting, the fire-fighting facilities in the hotel did not play any role. No pressure was exerted, and the switch was almost loose. Afterwards, the relevant person in charge of the Fire Bureau of the Ministry of Public Security made it clear that the results of the investigation of the “ 6.10 ” fire accident in Shantou, Guangdong Province showed that the hotel’s automatic alarm and fire extinguishing system did not operate during the fire.

1998 January 6, Changde City, Hunan Electric Co., hotel fires, the staff immediately got a fire extinguisher putting out the fire. However, when they used five dry powder fire extinguishers in a hurry, they found that none of the five dry powder fire extinguishers could only spray dry powder. Afterwards, as detected by the fire-fighting department, dry powder fire extinguishers equipped with the hotel actually had 40 % of dry powder fire extinguisher agglomerates, 35 % of the fire extinguisher gas leaked, and only 25 % could be used normally .

In March 1996 , a forest fire broke out near the children’s school of the Wangjiashan Coal Mine in Xiangtan City, Hunan Province. The coal mine security department quickly organized personnel to carry five fire extinguishers to fight the fire. The Chief of the Mine Protection Division first took the fire extinguisher to the fire. When he opened the second dry powder fire extinguisher, a sudden loud noise occurred, the head of the fire extinguisher rushed out of Simplified, hitting heavily on his forehead, causing his eyeballs to come out and comminuted fractures of the frontal bone and collapsed to the ground on the spot. What makes people feel bad is that. After testing, there is still one of the remaining three fire extinguishers with the same serious quality problems.

Inferior products can save fire and save people

According to industry insiders, taking the formal powder fire extinguisher as an example, the standard requires that the dry powder soda account for a minimum of half, and the proportion of high-quality product soda can reach 80 %. In fake and shoddy products, the proportion of soda is only 20 %. Some even only about 10 %. These substandard products use talcum powder, which costs more than 1,000 yuan and one ton, to replace soda which costs nearly 3,000 yuan. Therefore, this type of fire extinguisher that cuts corners and works should not be said to be able to extinguish fires and save people. After use, it may also lead to counterproductive effects.

A person in charge of the technical department of the Fire Prevention Department of the Guangdong Provincial Public Security Fire Brigade said: “The dry powder used for counterfeit fire extinguishers is definitely unqualified, and the proportion of talcum powder added is particularly high, and neither the fire extinguishing effect nor the extinguishing time can be grasped. In addition, the poor fire extinguisher steel plate can not meet the required requirements, and is prone to explosion.” According to him, in terms of material selection, many production companies drill the standard well without emphasis on the material and thickness of the hole, more choice of the market Hot-rolled steel plates, which are less expensive, are used as the box material, and the thickness of the steel plate tends to become thinner. Some companies choose the thickness of the fire box door glass to 2 . 5mm or even thinner, individual even using recycled glass does not meet the standard requirements. In terms of processing, the quality of production of some companies is not high, even more rough, flatness, clearance is too large, the door opening angle is too small, affect the use of results and aesthetics. In the area of ​​signs, incomplete signs are common. Many companies do not specify production dates, models, and specifications. The fonts are too small, and individual companies are greedy for convenience. They actually label the fire hydrant boxes and fire extinguisher boxes together.

Knowing to buy fake is like throwing oil on the fire

It is understood that fire safety awareness is weak in reality, and there are many people who are greedy for cheap, fake and fake.

Many units that purchase fire-fighting products lack relevant fire-fighting knowledge, do not understand the performance, model, and specifications of the product, do not understand the requirements of relevant laws and regulations, and some even have unclear product names, and it is impossible to distinguish the quality of fire-fighting equipment. Which kind of product is cheaper to buy, what buys only has played the role of decoration. As for the product is not qualified. No matter if it's used, as long as the unit doesn't fire, these things don't work. Of course, no matter how quality it is, no one will pursue it. Some construction units to save money. The use of fire doors with ordinary wooden doors, can not meet the requirements of fire prevention: indoor fire hydrant water guns should be aluminum products, but the vast majority of quality but off: the hose and fire hydrant interface seal poor, new water Severe water leakage occurs at one time when the interface is used, in the event of a fire. The firefighting requirements cannot be achieved at all: What is more, some fire pumps in the pumping rooms of the units have not been tested by the National Testing Center at all, and there are no test reports. They are unqualified fire-fighting products.

Secondly, the misunderstanding in the field of use of fire-fighting products also caused the quality of fire-fighting products and market confusion. Many units are only satisfied with the facilities in building automatic firefighting facilities. As for the management of the facilities, they are indifferent. Some non-specialists are on duty, and some on duty personnel lack expertise. Some automatic firefighting facilities are not regularly inspected, tested and cleaned. Frequently cause false positives and failures. The construction of automatic firefighting facilities did not play its role in emergency response.

In addition, in the maintenance of firefighting products. The use of units is also in the form of a point. According to firefighters, they often find that the fire extinguisher is under-pressurized, the injection time is too long or it cannot be sprayed, and the quality of the powder is poor. Such a fire extinguisher can only be an ornament without fire fighting performance.

How to identify counterfeit and inferior fire products

The surface and packaging of regular fire protection products should have clear and durable signs, including product marks and quality inspection marks ( certificate of conformity ) . The product mark shall include the manufacturer's name, address, product name, product model ( specification ) , main technical coefficient, product trademark, production date and product number, and implementation standard code. Quality inspection marks should include inspectors and qualified marks.

The appearance of fake and shoddy products is often vague, rough, incomplete, and not durable. Such as counterfeit fire hydrant valve body on the trademark casting is not clear; no specifications on the interface model logo; fire hose does not mark the "fire" word, intentional confusion and so on.

In addition, the use of non-combustible materials or non-flammable materials on the surface of fire-fighting product entities using flammable or flammable materials may also be used as a basis for judging them to be counterfeit and inferior products. Such as fire emergency lighting, fire hydrant box surface should be required to use non-flammable materials or non-combustible materials, such as rejection of plexiglass and other combustible materials.
