Flammable and toxic chemicals storage cabinets(time control switch device)

Background analysis

With the rapid development of social economy, the chemical industry has become a pillar industry of the national economy, and China has become a major country in the production and use of hazardous chemicals, in quantity and scale.

In recent years, with the occurrence of particularly major accidents, systematic safety risks have formed in the production, storage, transportation, use, disposal and other links of hazardous chemicals, seriously damaging the safety of people's lives and property, affecting high-quality economic development and social stability, and people talk about "chemical" color change. The policy environment, social environment and public opinion environment have encountered more severe challenges than ever before, and the safety work of hazardous chemicals needs to be comprehensively strengthened!

From the analysis of policies and regulations issued in recent years, the relevant regulatory documents for the storage of hazardous chemicals will be gradually updated and improved in the future, and since the issuance of Order 591 of the Regulations on the Safety Management of Hazardous Chemicals in 2011, including the newly released GB18265-2019, there are units for the storage of hazardous chemicals. Safety facilities and equipment such as monitoring, monitoring, ventilation, sun protection, temperature control, fire prevention, fire extinguishing, explosion prevention, pressure relief, gas protection, neutralization, moisture protection, lightning protection, static electricity prevention, corrosion prevention, leakage prevention, protective embankment or isolation operation shall be set up in workplaces according to the types and dangerous characteristics of hazardous chemicals produced and stored. And in accordance with national standards, industry standards or relevant state regulations to carry out regular maintenance of safety facilities and equipment, to ensure the normal use of safety facilities and equipment. The Ministry of Public Security has made clear provisions on the storage, management and use of controlled hazardous chemicals, which must have special facilities, and hazardous chemicals must be partitioned, classified and stored in separate warehouses. Strengthen the safety management of hazardous chemicals, prevent and reduce hazardous chemical accidents, ensure the safety of people's lives and property, and protect the environment.
