Very thin and brittle, it breaks the helmet hanging on some construction sites!

The helmet as an umbrella on the construction worker's head at the construction site can avoid or reduce the direct injury to the head caused by the falling object. The warning sign “No helmet is prohibited from entering” can be seen everywhere on the construction site. However, is it really safe to wear a helmet? In early April, the reporter received a cry from Ms. Liu, saying that her husband’s head was marred by marble during construction on a construction site near Linhe Street in Changchun City in August last year. He was identified as a first-degree disability several days ago and is still not aware of it. clear. Ms. Liu believes that her husband’s injury was an accident. However, if the hard hat he wears is a regular product, it will not cause the tragedy of the three-inch deep hole in her husband’s head. In spring, most of the construction sites in Changchun have been started. Whether or not the eye-catching helmets on the workers' heads can really ensure safety has become a hot topic. Recently, reporters spent a week investigating the safety of hard hats.

Wearing a hard hat has also been bruised.

On the morning of April 12th, the reporter saw the old king who had been hospitalized for 8 months in the Brain Surgery Department of the Lecture House of the University of Chicago. Ms. Liu, the wife who sat aside, used her husband's hand massage from time to time. The next daughter was skilled in sucking her father with a twitching machine. Ms. Liu said, “Our hometown is located in Shulan countryside. When my husband came out for ten days last year, he came up with this. If he knew that it was so dangerous on the construction site, I said he could not get him out to work. The family is not like a family. Her husband has become a 'living man'. The family was poor, and her husband has suffered such heavy injuries. She has already built up a lot of debt.” When she talked about her husband’s injuries, Ms. Liu still had a hard time, she said, her husband. When the injured head was like a "bloody gourd," the worker said that when the marble collapsed, the helmet was broken on the spot. The debris also scratched his head and he saved more than seven hours in the operating room. Later, his life was saved. It is in a coma. Ms. Liu felt that half of her husband’s injury was caused by the unstabilized work of the upstairs worker when he was connected to marble, and there was also a lack of quality of the helmet and poor impact performance did not protect the head.

In response, the reporter interviewed Pharaoh's coworker Mr. Li. He told reporters, “At that time, the construction site was given a plastic safety helmet. We did not understand. The foreman let us wear it, and the helmet was very thin and light. Quality is not very good.” Another worker named Mr. Zhao said, “We are all coming out of a village. We saw that Pharaoh was so badly injured that my family did not let me come out to work. I didn’t do it soon. I went back to the village to plant land. I was a farmer. It was unclear how to wear a kind of helmet. However, I could see that the hard hat that was sent from the construction site was indeed unobtrusive and the position of the head was very thin.啥 effect."

In addition, Lao Wang, who was wearing a hard hat on the site and was still injured on the site, was injured on the head of Mr. Li from Nong'an County on March 22nd. During the treatment, there was a case of intracranial hemorrhage. The current treatment cost was It cost ten thousand yuan. Mr. Li’s brother said, “As a migrant worker, he came out to do more work to make more money. Now that something has happened, he realizes the importance of safety in the construction site. But everything is late. My brother was also wearing a hard hat. No one can use it at all, a brick helmet will be cracked, and it will be hospitalized now.” Mr. Shi, who came from the south as a construction worker in Changchun, was also injured in early April. He did not understand the correct method of wearing a helmet. The helmet was knocked off during construction, causing the head to be scraped by a rebar.

Hard hat color

Quality is also divided into grades

Regarding accidents caused by poor quality helmets, the reporter visited the labor insurance products store. During the visit, the reporter was surprised. The quality of the original helmets was also graded, and the quality of different colors was not the same.

On the morning of April 15, the reporter went to visit more than 10 labor insurance products stores located near the Liberal Road. "If you wear it yourself, you can buy a better-quality helmet and it is safe to buy a good quality one," said a store owner. "How much is it?" the reporter asked. The boss took out a pale yellow helmet and said, "The quality of this helmet is OK, 30 yuan." The boss said. Subsequently, the reporter visited the construction site as a buyer. "I have a helmet to check for. At 7 yuan per top, you can also negotiate if you buy more, and many of the hats I buy here are of fair quality, but from the appearance, there is no problem." The boss introduced.

On the afternoon of April 16, the reporter came to several labor protection supplies stores on Linhe Street. This reporter really saw the grades and differences of the helmets. It was related to the color of the hats. The reporter went to a store in a labor insurance library. The owner of the shop watched the reporter's gaze and watched the helmet hanging in the house and introduced it enthusiastically.

"How many top hats do you buy? For whom?" asked the woman's boss. The reporter indicated that he would buy for the workers on the construction site. The owner was very happy, as if a big business came. Afterwards, the reporter looked at the six colorful helmets hung on the wall. "Is there any difference in the price of helmets of different colors?"

Owner: That's for sure. White is the leader who wears the shoes. The quality is good. He dares to wear quality hats for leaders.

Reporter: What type of helmet is worn by ordinary workers?

Owner: This yellow, light yellow and orange, (say, the owner took out four hard hats to start the presentation) This is the light yellow is the sales are better, the general construction site to buy this, 7 yuan a top .

Reporter: What kind of quality?

Owner: Generally nothing, you see that I sold for so long, and no one came to me, but this kind of helmet, from the perspective of the price, you know what the grade is, if you ask too much, Then buy that kind of expensive. However, the average worker wears a yellow one. The quality is almost as good as it is. What kind of money does this hat cost you hundreds of dollars?

The owner of the shop said that if he can buy a large amount of money, he will be able to get 3.5 yuan for each top hat of 4 yuan. In the end, the reporter bought a yellow orange helmet at a price of 4 yuan and bought a pale yellow helmet at a price of 7 yuan. The reporters carefully checked after purchase, and only the manufacturers were obscurely printed on the location of the brim, but there was no trademark, model number, year of manufacture, production certificate, inspection and verification, and production license number.

A poor quality helmet crashes

The helmet has two basic properties, impact resistance and penetration resistance. According to the national standards of the helmet, the qualified helmet can withstand the impact of a steel hammer weighing 10 pounds falling from a height of 1 meter. It can also ensure that the cone head is not in contact with the scalp after penetration of the 6-pound steel cone falling at the same height. So, can the cheap helmets purchased by reporters meet the above criteria?

During the test, the reporter used a piece of brick about 4 pounds heavy and fell freely at a height of 1 meter from the helmet. As a result, the helmet made a loud crash and the hat cracked a big hole about 6 centimeters. So is the helmet worn by the wounded worker Lao Wang so “fragile”?

The reporter went to the site where Pharaoh worked and bought a hard hat that he was using. "Our hat is strong, and the workers wear this kind of thing, which the foreman buys." The worker pointed at his own hardhat.

This hard hat, considered to be "sturdy," was safe and sound after being attacked by the bricks. However, it was slammed by the newspaper reporter and left a big hole in the hat.

Why are these helmets so fragile? According to insiders, the problem lies in the production of raw materials. Hard hats should have been made of engineering plastics. The hats thus made have good characteristics such as impact resistance, but due to the high price, only large companies can afford them. The other kind is called recycled material, which is extracted from the waste of various plastic products. Because the price is cheap and favored by small workshops, the hat made from recycled materials is just a decoration. “When it comes to things, the fart is not used.”

Most workers do not know how to properly wear a helmet

On April 17th and 18th, the reporter visited several construction sites in Changchun City and found that most workers would not wear a safety helmet correctly, nor would they identify whether the safety helmet was regular. In a construction site near Century Avenue, a worker wears a hat and some wear a wool hat because of the cold weather. He only wears a helmet and a hard hat. The reporter spoke to the worker who was working. He said, “My helmet was made by a safety officer on the construction site. The workers were basically all dressed. But it was too cold and I wore a wool hat inside. But this way The mandible cannot be attached."

At a construction site near Liuying Road, hard hats worn by workers are not very standard, and the majority of workers have no attachment to the mandible belt.

In a construction site under construction near Linhe Street, a steelworker who is transporting rubbish to the outside said: “If I don’t wear a hat, let the security guards see it, and you’ll have to punish it, but the mandible belt is generally not tied. not feeling well."

In view of the situation of workers in the construction site, the reporter interviewed Mr. Li, an engineer of a construction company in Changchun City. He said that in the construction site, wearing helmets of different colors, the identities of the representatives are different, and white represents the leader. Blue represents management personnel, yellow represents on-site construction personnel, and general outsiders wear red safety helmets. He brought a red helmet to explain to reporters: “This hat is worn by me on the construction site. The price is 60 yuan. The cap is hemispherical, strong, smooth and flexible. The shell can withstand the impact. The impact and penetrating power of the object. There is a space between the cap and the cap lining to buffer and disperse the instantaneous impact force so as to avoid or reduce the direct damage to the head.” Subsequently, Mr. Lee pressed the fist with a fist The pad soon bounced up, indicating that it could withstand the impact. Mr. Li said that when the worker's head is impacted by a falling object, he can use the helmet cap and shell lining to instantaneously decompose the impact force to the entire area of ​​the skull so that he can play a protective role.
