Why safety harness required?

Aerial Working has a higher risk, especially in the construction site, if the operator is a little careless, they will face the risk of falling.


The use of seat belts must be strictly regulated. In the process of enterprise development, there are also a few people who use seat belts not strictly abide by the regulations and cause serious consequences.

According to the statistical analysis of aerial Working fall accidents, about 20% of fall accidents above 5m and 80% below 5m. Most of the former are fatal accidents. It can be seen that it is very necessary to prevent falling from height and take personal protective measures. Studies have found that when falling people accidentally land, most of them land in a prone or prone position. At the same time, the maximum impact force that a person's abdomen (waist) can withstand is relatively large compared to the entire body. This has become an important basis for the use of safety belts, which can enable operators to work safely at high places, and in the event of an accident, they can effectively avoid the huge damage to the human body caused by a fall.


It is understood that in the process of industrial production, there is a high rate of casualties caused by falling human bodies. The statistical analysis of human fall accidents accounts for about 15% of work-related accidents. Many accidents have shown that accidents caused by aerial Working falls cause casualties, most of which are caused by operators not wearing seat belts in accordance with regulations. Some workers think that their operating area is not high because of their weak safety awareness. It is convenient not to wear seat belts for a while, which leads to accidents.

What are the consequences of working at height without wearing a seat belt? How does it feel to be smashed without wearing a helmet when entering the construction site?

Setting up a safety experience hall is an important measure for the safe and civilized construction of construction sites. More and more construction units are installing physical safety experience halls and VR safety experience halls to educate construction workers on safety issues.

One of the construction engineering safety experience halls covers an area of ​​600 square meters. The project includes more than 20 items such as helmet impact and hole fall, so that people always sound the alarm for safety in production.

1.300g iron ball hitting the helmet

You can wear a safety helmet and walk into the experience room. The operator presses a button and a 300-gram iron ball on the top of the head falls and hits the safety helmet. You will feel a faint discomfort on the top of the head and the hat will be crooked. "The impact force is about 2 kilograms. It's okay to have a helmet for protection. What if you don't wear it?" The site safety director said that this experience warns everyone that not only should the helmet be worn, but also firmly and firmly.

2. The posture of a heavy object with one hand is incorrect

There are 3 "iron locks" weighing 10 kg, 15 kg, and 20 kg on one side of the experience hall, and there are 4 handles on the "iron lock". "Many people like a heavy hand-held object, which can easily damage one side of the psoas muscle and cause pain during the process of exerting force." According to the director, when you don't know the multiple objects on the construction site, you should lift it with both hands and use both hands to share the weight Strength, so that the lumbar spine is evenly stressed. The things you lift should not be too heavy. Brute force hurts the waist the most. It is best to use tools to carry heavy things.

Feel the fear of falling from the entrance of the cave

Buildings under construction often have some "holes". If fences or shrouds are not added, construction workers can easily step on them and fall. The experience of falling from a hole more than 3 meters high is to let the constructors experience the fear of falling. Working at heights without a seat belt, the consequences of falling are disastrous. In the seat belt experience zone, the skilled worker straps on the seat belt and is pulled into the air. The control system can make him "free fall". The feeling of falling in weightlessness in the air makes him very uncomfortable.


By simulating the on-site construction environment, the safety hall allows construction workers to personally experience the correct use of safety protection equipment and the momentary feelings when danger occurs, and more intuitively feel the importance of construction safety and protection equipment, so as to truly improve safety awareness and prevention awareness. Bringing experience is one of the key.


Functions of the seat belt experience zone:

1. Mainly demonstrate the correct wearing method and scope of application of seat belts.

2. Personally wear different types of safety belts, so that the constructors can experience the feeling of an instant fall at a height of 2.5m.

Specifications: The frame of the seat belt experience hall is welded with 5cm×5cm square steel. The cross-beam and column cross-section dimensions are both 50cm×50cm. They are connected by bolts, the height is 6m, and the outer side between the two columns is 6m long. (According to the specific needs of the construction site)

Material: 50-shaped angle steel combined welding or steel pipe erection, advertising cloth wrapped, 6 cylinders, 3 points. There are many reasons for accidents, including human factors, environmental factors, management factors, and working height. You should know that it is not only the height of 2 meters or more that is dangerous to fall. In fact, even if you fall from a height of more than 1 meter, When the vital part of the body touches a sharp or hard object, it can also cause serious injury or death, so the safety belt experience on the construction site is essential! Just imagine, the real construction work environment must be higher and more dangerous than the experience hall.

In safety production, we can see that safety belts are the most powerful guarantee for aerial Working, not only for yourself, but also for your family. Please be sure to wear safety belts during construction.
