A new generation of landscape - spider man

Not long ago, when two external wall cleaners were working at a height of 20 stories or more above a building on West Yan'an Road, they fell from a height due to a broken rope and died.
A broken rope caused two workers to die. Today, after the "Spider Man" has worked hard and cleans the city's tall buildings, people are embarrassed to replace their safety concerns.

In the investigation, the reporter found that there has been no mandatory access mechanism in the area of ​​high-altitude cleaning and there are no relevant legal norms. This means that anyone can get involved in this high-risk industry, organize a high-level cleaning team, and share a slice of the high-altitude cleaning industry.

When supervisors focus their supervision on whether workers are “certified”, there are still many worrying situations that have been overlooked.

â–  High-rise buildings in the city, "Spider Man" gradually becomes a scene

Workers who climbed on the outer walls of high-rises in the city to clean their work, hanged themselves on several floors, dozens or even dozens of high-rise buildings by means of a safety rope, and began to slide down from the top of the building. Glass and exterior walls. Because they can make good use of various safety devices and their own balance capabilities, like spiders on the side of high-rise buildings up and down, people are known as "spider people."

Chen Jian from Sichuan has been a “spider man” for 7 years. His daily work is to hang himself at high altitude. He is holding a long rope with one hand and a long brush in one hand. He continuously draws the prepared syrup from the bucket behind him. Complete various cleaning actions. In order to be able to clean the wall of the largest area, he would constantly kick with his feet in the sky to move his body...

Chen Jian clearly remembers that just one day after he had just been a spider man, he was arranged to clean a 40-storey building, with the highest point about 120 meters above the ground. He fastened the belt on the roof of the building, then stood in the hanging basket, while cleaning the outer wall, slowly moving down the rope and moving to the 20th floor, the basket was suddenly blown back and forth by the wind. The basket slants outwards and he loses the weight when he stands in the basket. The people lean backwards, and the cleaning levers in his hand fly out a few feet. Fortunately, when the cleaning rod fell to the ground, it did not reach anyone. Fortunately, he was wearing a safety rope. The basket was quickly pulled up by the colleague and he was safe. But when he was scared, he was still scared.

■There is no absolute security for an “ascend the erection work permit”

With the increasing number of high-rise buildings in the city, the demand for high-altitude cleaning is also increasing. There are more and more “spider people” such as Chen Jian, but the status quo of the high-altitude cleaning industry is not optimistic. In the past two years, news of the fall or fall of the Spiderman has often been called for.

Zhang Jiaming, head of the Beijing Municipal Work Safety Supervision Bureau, said in an interview that an average of 40 people in Beijing died in high-altitude operations such as building cleaning and air-conditioning installation. According to statistics, there are currently more than 10,000 people in Beijing engaged in high-altitude operations such as building cleaning, among which there are many "illegal" employees.

The so-called "illegal" refers to "unlicensed" practitioners. From March 2009, erection workers were listed in the scope of special operations personnel in major cities such as Beijing and Shanghai. They must undergo safety technical training assessment and obtain the corresponding special operation certificate, ie, “elevation erection operation certificate”. After the job can be done on the job. At that time, Shanghai required the training and evaluation of “Spider-Man” before September 2009. If the construction party hires untrained personnel to carry out work at heights, serious consequences of accidents will be held criminally liable.

Chen Jian believes that the original intention of this provision is to protect the "Spider Man," but as far as he knows, there are still many "Spider Man" who have no cards to take up. The main reason is that the high-altitude cleaning industry is highly competitive. Some companies have even reduced their security costs. How can they send employees to train?

In fact, this is more of a concern for Chen Jian and his workers. If the company cuts down on safety equipment in order to save costs, even if there is an “ascension certificate”, it does not mean absolute safety.

â–  Spiderman needs protection rope more than access threshold

The two “Spider-Man” crashes occurred on West Yan'an Road. Both of them held the “Climbing Erection Permit”, but were killed because they lost a protective cord.

According to the National Standard for Safety Technology for Suspension Operation of Seat-type Single-propelled Suspenders (hereinafter referred to as the "Technical Code"), when workers perform aerial suspension operations, they slide down the "work rope" and there is another next to it. The “safety rope” is interlocked with a safety belt on his body through a device called a self-locking device. The “safety rope” is connected to a fixed long rope at the top. This rope bears the impact of the human body when it falls. It is called "Lifeline". This "work rope" should be stably fixed on a hanging point device with a load capacity of over 330 kg, and a hanging point device should only allow one worker to occupy it.

In this incident, the “life rope” used by the two workers was not buckled with the belts that were tied around the waist, and they both used the same “work rope” and eventually caused a rope to break. Falling dead.

In fact, the "Technical Regulations" have very strict technical requirements for the protection of ropes, and the cost is not unreasonable: a 100-meter protective rope is sold at a price of 10,000 units and its service life is limited to a maximum of one year. However, with the increasingly fierce competition, regular and large-scale cleaning companies are required to clean about RMB 2 for a one-square-meter building facade. In some enterprises, the charges can be reduced to 88-points per square meter. The hidden danger is indeed worrying.

â–  Only relying on corporate self-discipline does not work

There is no doubt that high-altitude cleaning is a work that requires a great deal of professional competence and requires great emphasis on safety. However, the reporter found that in this field, there is no mandatory access mechanism in the country.

Although the China Association of Occupational Safety and Health High-altitude Service Industry Branch has already introduced the "Administrative Measures for Safety Production Certificates for High-altitude Cleaning and Suspension Operations (for Trial Implementation)", this method only shows that: "No high-altitude cleaning and suspending operations enterprise safety production certificate has been obtained. The member companies should not engage in high altitude cleaning and suspension operations" and have no mandatory effect. And, this high-level service industry branch is only an industry organization organized spontaneously by cleaning associations in major cities in the country.

Similarly, in Shanghai, it is the building (structure) cleaning and cleaning professional committee affiliated to the Shanghai Municipal Environmental Sanitary Industry Association, which is responsible for the certification of cleansing companies and the issuing of grade one to three level certificate functions. This committee is composed of several high-altitude cleaning and cleaning The self-regulatory organization initiated by the company lacks mandatory provisions.

It's not easy to be a spider man

The special types of work at heights do not work well for everyone. They must undergo a rigorous physical examination. People with fear of heights, high blood pressure, heart disease, and arthritis cannot engage in the work of climbing. After strict training and appraisal to obtain the climbing operation certificate, "Spider Man" can be employed. In addition, because the "spider man" in the cleaning process needs to rely on the sling to complete the work, therefore, there is also a requirement for the height and weight of the practitioner. The best height is between 1 to 70 meters and 1 to 75 meters, and the best weight is about 62.5 kg. 70 kilograms are not suitable for working at heights.

To clean the special architectural structures such as the Oriental Pearl Tower, the swinging of the air, the tilting and flipping of the body must all rely on mutual trust and cooperation, so teamwork is also very important.

In addition, the climbing operations are also limited by the natural climate. For example, the external wall cleaning must be carried out under good climatic conditions, and the wind must be stopped above the 4th level. Therefore, the wind power should be measured before the work, especially the high-altitude wind power; rain, snow and fog. , poor visibility and air temperatures above 35°C and below 0°C are also not suitable for exterior wall cleaning.
