Industrial safety fence: steel guard to build a strong factory safety line

Industrial manufacturing is an important pillar of the national economy and an important tool for achieving development and upgrading.From a poor start to rank first in the world in the scale of manufacturing industry, China has completed the industrialization process of developed countries for hundreds of years in a few decades, the real economy has continued to grow, and the development of major countries has consolidated its capital.At the same time, "Made in China" has become a new business card for Chinese industry to shine in the world.

Since the 18th National Congress of the Communist Party of China, the Party Central Committee has insisted on leading the construction of a modern industrial system with scientific and technological innovation, and the manufacturing of large countries has rapidly advanced to high-end, intelligent and green.Under the rapid changes of The Times, the industrial manufacturing field has begun to move toward a new industrial era of "intelligent manufacturing" with artificial intelligence, big data computing and industrial Internet as production orientation, injecting strong impetus into economic development.

With the rapid development of industry, as well as the large-scale, large-scale and intelligent trend of key process equipment in process industry, the safety risks and risks of industrial production have also sprung up, whether it is the unsafe state of things or the unsafe behavior of people, it is possible to cause serious accidental injury accidents, and the consequences can not be redeemed.Here are two examples of accidents:

Case 1: Lifting hole without guardrail, accidentally fell and died

A factory replaced the belt to open the lifting hole, and only set up a simple fence with nylon rope that could not play any protective role, and a coal accumulation personnel fell from the lifting hole and died.

Incident review: The maintenance personnel of a factory opened the lifting hole (25m elevation) between the lifting lead to replace the coal conveyor belt, and only used a nylon rope as a simple fence.In the morning, the person in charge of the work led Yue Mou and others to arrive at the hanging lead, dredging the coal cylinder work, although it was found that the lifting hole was not set up fences, did not take protective measures, and began to work.A worker hit the coal cylinder with a sledgehammer, Yue fell from the lifting hole to the ground (25m) to avoid the sledgehammer, and died.

Reasons and exposure problems:

• maintenance personnel opened the lifting hole, did not set a safe and reliable rigid temporary fence;
  
  
• Although the nylon rope is used to set up a simple fence, it is too loose and falls to the ground, which can not play any protective role;
  
  
•  The person in charge of the work led the operators to the scene, although they found that the temporary fence could not play any protective role, and did not require the maintenance personnel to set up a reliable rigid temporary fence;
  
  
•  In the case that the temporary fence does not play any protective role, the person in charge of the work has not taken other protective measures and blindly organized the start of work.
  

Case 2: No safety barrier was installed and the person in charge was sentenced

The boss of a machinery company in Qidong, Jiangsu province, neglected safety production education and did not set up safety guardrails around the quenching oil pool, resulting in the tragedy of employees falling into the oil pool and dying.The Qidong court made a judgment of first instance on Gao Mou's crime of major labor safety accidents, and Gao Mou was sentenced to fixed-term imprisonment of one year and six months, suspended for two years.

Incident review: On September 13, 2017, a company employee surnamed Huang accidentally fell into the oil pool with an oil temperature of 80 degrees Celsius while working around the quenching oil pool, and died after being rescued in hospital.

The production safety accident investigation team determined that the accident caused a direct economic loss of more than 1.2 million yuan, and the company's quenching oil pool did not set up safety guardrail is the direct cause of the accident.Gao Mou, as the main person in charge of the enterprise and the safety officer, did not supervise and inspect the safety work, failed to eliminate the hidden dangers of production safety accidents in time, resulting in accidents, is the person in charge of the accident.

The Qidong Court held that Gao Mou, as the legal representative of the enterprise and the main person in charge of the safety production enterprise, knew that the safety production conditions did not meet the state regulations, still organized workers to produce and operate, resulting in one death, and its behavior has constituted a major labor safety accident crime, and should be investigated for criminal responsibility according to law.Combining the circumstances of his crime and his repentance, Gao was sentenced to one year and six months in prison, suspended for two years.

There is no small matter in production safety, and every accident is a lesson in exchange for blood and life.If you do not pay attention to the safety of production in the industrial environment, and eventually lead to serious accidents, once the criminal law or will face prison disaster.

Legal tip: Article 134 of the Criminal Law of the People's Republic of China [Crime of Major Liability accidents] : Whoever, in the course of production or operation, violates the relevant provisions on safety management, thus causing a major casualty accident or other serious consequences, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention;If the circumstances are especially serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years.

The above two safety accident cases have one thing in common, one is the lack of safety awareness, the other is not set up safety fences in dangerous areas, and make preventive actions in advance.So, what is a security fence?What exactly does the security fence do?

In practical application scenarios, the safety fence is a barrier commonly seen in factory workshops, which plays a role in regional division or safety isolation warning of large processing equipment, and can be widely used in various industrial environments, such as machinery manufacturing, automobile manufacturing, electronic manufacturing, food processing and other industries.In these industries, safety fences are often used to protect production equipment, prevent personnel from straying into dangerous areas, isolate safety risks, and plan production areas.

First, security fence protection system

According to GB/T 42627-2023 "Safety Requirements for Mechanical Safety fence Protection Systems", the fence protection system is an integration of fences, security gates and interlocking devices, and can be used to physically isolate or restrict access to dangerous areas in an area.

Security fence function

Isolation protection: In the process of industrial production, some large mechanical equipment needs to be in a state of high temperature, high voltage and high voltage for a long time, if there is no safety fence isolation, it may cause harm to the surrounding environment and personnel. The safety fence has the function of isolation and protection. First, it can separate the equipment area from other areas to ensure the normal operation of the equipment. Second, it can prevent other personnel from straying into dangerous areas, protect the surrounding environment and personnel safety, and reduce the probability of accidents.

Warning function: The security fence usually uses eye-catching colors and signs, as well as obvious warning signs to remind personnel to pay attention to safety and not to approach the equipment area. This can increase the safety awareness of personnel and reduce the occurrence of accidents caused by negligence.

Reasonable planning of the use of places: The security fence can also divide the factory area, help the workshop materials to be neatly placed and beautiful, and improve the reasonable layout of the space area. It is of great significance to improve the production environment, increase the production efficiency and optimize the production process.

Convenient equipment maintenance: The setting of security fences can restrict unauthorized personnel from entering the equipment area and protect the safety and integrity of the equipment. At the same time, the safety fence can also provide a relatively independent working space for maintenance personnel, convenient for them to carry out equipment overhaul and maintenance work.

Second, fence safety requirements

Any safety regulation is based on an in-depth study of human behavior and environmental factors, and its purpose is to prevent accidents. GB/T 42627-2023 "Mechanical safety fence protection system safety requirements" for the fence safety requirements made clear.

Size requirements: GB/T 42627-2023 "Mechanical safety fence protection system safety requirements" 5.1.1, in the case of no additional protection measures, the lower the height of the fence, the greater the size of the fence from the danger zone. Usually, the height of the fence should choose 1600 mm, 1800mm, 2000mm or 2200 mm.

Strength requirements: GB/T 42627-2023 "Mechanical safety fence protection system safety requirements" 5.2.3 stipulates that the fence should have sufficient impact resistance to foreseeable impact from the danger zone, the impact risk and impact energy of the parts or workpieces of the machine in the protection area should be assessed, and the impact resistance of the fence is not less than the foreseeable impact energy. If the impact energy of the mechanical moving parts is difficult to evaluate, it is appropriate to choose a fence with an impact resistance of not less than 1600J.

Third, fence purchase and maintenance

Safety fence is of great significance in ensuring personnel safety, limiting risk transmission, improving work efficiency, strengthening safety management, protecting equipment and property, and establishing emergency channels. Therefore, in the factory planning and production process, the setting and maintenance of safety fences should be fully considered.

When purchasing industrial safety fences, factors such as the material, structure, size and warning effect of the fences should be considered. At the same time, it is also necessary to choose the appropriate fence type and specification according to the actual needs and budget of the factory.

From the material, structure and size of the security fence,Bytorent safety fence selection of durable, corrosion-resistant material, the use of whole body spray technology and modular structure, further strengthen the overall strength, with high standard, high performance, high corrosion resistance and other advantages.

The standard size of Bytorent safety fence is 2000mm in height / 1000mm in width, and the impact strength is up to 1600J, which conforms to the ISO14120 safety fence standard and GB/T 42627-2023 "Safety Requirements for mechanical safety fence protection System".

Starting from the warning effect, Bytorent metal mesh of the safety fence uses the color combination of black panel + yellow column, the color is eye-catching, effectively improve the identification of the fence, and visually more conducive to our observation of the protection area in a complex industrial environment, grasp the dynamics and situation of the personnel in the operation area, timely discover and deal with potential dangers, and ensure the safety of equipment and personnel.

From the actual needs and budget perspective, Bytorent safety fence supports the full modular design, can provide customized customized services according to the specific needs of equipment protection, accurately match the actual environment and safety requirements of the factory, and reduce the safety risks caused by insufficient space or unreasonable layout.

In addition, according to the risks existing at the scene, other safety protection devices should also be installed on the security fence, such as safety interlock switches, non-contact switches, internal escape handles, warning tags, etc., to further strengthen the physical isolation and protection role, and improve the level and effect of safety protection.

Regular inspection and maintenance of the security fence is the key to ensure its long-term use. Check whether the connector of the fence is loose, whether the mesh is broken, and whether the warning signs are clear. The problem should be repaired or replaced in time to ensure the integrity of the fence and the warning effect.

In the issue of safety, prevention is more important than post-processing, a small negligence or neglect may lead to serious consequences, so we must always be vigilant and take preventive measures to avoid the occurrence of accidents.
