Introduction
Special operations are inseparable from the production and operation of chemical enterprises, and special operations, especially hot work and confined space work, are inseparable.
Industry is one of the main causes of accidents. According to statistics, more than 40% of chemical production safety accidents are related to special operations.
close. The frequent occurrence of accidents in special operations is mainly due to the inadequate implementation of the special operation management system of the enterprise, the unclear identification of risks before operation, and the
In the process, the risk management and control were not in place and the guardian's emergency response ability was insufficient.
In order to strengthen the management and control of safety risks in special operations, curb special operations, especially those engaged in hot work and operations in confined spaces.
The occurrence of large-scale production safety accidents, it is necessary to further clarify the safety management requirements of special operations through standard specifications, so as to prevent the current special operations.
Industry management standards are revised.
