Shortly explain what are the requirements of chemical overhaul on safety as follows:
1. Before overhauling, overhauling program should be prepared, the implementation of the project division of labor, the implementation of the supply of materials, the implementation of safety measures, the implementation of safety education. Overhaul management should be based on the project, safety measures to be taken to confirm the system.
2, should establish and improve the safety assurance system, a clear responsible person at all levels of overhaul, where more than two people work overhaul project ~ should be designated as the person in charge of safety ~ work construction personnel to do a clear task, clear safety measures, clear safety regulations.
3, should be developed to open and stop the program and overhaul safety precautions, held a variety of scales, types of mobilization, according to the project organization to learn, technical briefing, fully grasp the process of opening and stopping and overhaul the site of the main points of safety, and to further establish the "safety first" idea.
4, the person in charge of overhauling equipment should be safe to open and stop, insert blind isolation, cleaning, replacement, cutting off the power supply and other safe delivery conditions are responsible for. High-pressure equipment pressure relief, to change to low-pressure meter or water column meter, verify that the pressure has been unloaded, toxic and hazardous materials should be discharged to prevent dead ends and residual pressure.
5, should establish a high degree of responsibility, strict ticket management system. Enterprises should generally establish the ticket: fire permit, tank safety permit, earth moving permit, work permit, equipment maintenance permit;
Pumping blind safety permit, disconnection contact ticket, lifting safety ticket, electrical safety operation ticket, power outage contact ticket, electrical safety ticket, etc.. Ticket listed in the safety measures, before the construction of the project manager and the constructor to confirm, in order to start the operation
6, overhaul the site should be kept open fire escape, first aid and medical organization is sound, to achieve standby status.
Chemical industry is "chemical process", "chemical industry", "chemical engineering" and other abbreviations. Any technology that uses chemistry to change the composition or structure of a substance or to synthesize a new substance is a chemical production technology, or chemical process, and the resulting product is called a chemical or chemical product.
In the beginning, the production of such products is a handmade workshop, and later evolved into factories, and gradually formed a specific production industry that is the chemical industry. Chemical engineering is the study of chemical products production process **** the law of a science.
Human beings have a very close relationship with the chemical industry, some chemical products in the history of human development, plays an epoch-making important role, their production and application, and even represents a certain stage of human civilization
