Aluminum shears cut scrap metal and help to separate different material types, earning you more money from your metals. Our shears are ideal for recycling scrap bar, tube, extrusions, car radiators, gear boxes and gate valves. We have been manufacturing alligator shears for more than 30 years. Ecohydraulic shears come in all sizes and are typically described according to blade length in mm. They can be powered by both single and 3 phase power supplies. Some shears have a diesel option. Operator safety is upper-most in mind so our range of shears are equipped with blade guards and foot-operated switches.

Only one valve should be closed without shutting down, and it would even lead to such serious consequences. When I was shocked, the author thought that if there was another person confirming the operator's operating procedures, this major accident might not happen. However, according to the author's understanding, such systems are rarely implemented in China, including chemical companies such as Jilin Petrochemical, which are well-known for their strict management.
Summarizing the numerous lessons learned from safety incidents such as Jilin Petrochemical, we will find that many of them are caused by irregular operations of operators, including operational errors, use of unsafe equipment, risky access to dangerous locations, and disposal of inflammable and explosive materials. Improper and so on. Although various chemical companies have very detailed provisions on safety production, these regulations do not guarantee that every employee can comply with them from time to time. Lack of safety knowledge and experience, excessive fatigue, lack of concentration, and so on, all of which can lead to operationally unsafe behavior. Now, the company's production operations are often performed by an operator. Is it done according to regulations? Only by his own judgment, there is no second person to confirm it, and there is no effective supervision. However, it is undeniable that the operatives in each post are engaged in repetitive work for a long time, and they are prone to paralysis and lax thinking. The operation may not be done seriously, or it may not be done, thus creating a security risk. And this kind of hidden danger will be hard to find. Therefore, the author believes that all chemical companies should establish operational confirmation systems for critical and prone to safety accidents. Each step should be confirmed and signed by another person. Your own name. In this way, although it is a little troublesome, it is obviously effective to ensure that every step of the operator's operation is correct and production safety is guaranteed.
The "11·13" big explosion of Jilin Petrochemical Shuangfen Plant, which resulted in the deaths of five persons, one missing person, more than 60 people injured in various degrees, and forced displacement of thousands of residents, has been identified as the direct cause of the accident. When negligence occurred during parking, the valve that should be closed was not closed in a timely manner. The misoperation caused the temperature of the feed system to be excessively high for a long time, resulting in bursting, which caused a series of equipment to explode in succession.
