China News Service, March 26. According to the website of the Emergency Management Department, the Emergency Management Department today announced a batch of typical cases of production safety accidents in limited space operations, supervised and urged profound lessons learned from accidents, and promoted the tightening of safety responsibilities.
The Emergency Management Department stated that in recent years, large production safety accidents such as poisoning and suffocation in limited space operations have occurred frequently, and the safety situation is complex and severe, causing major losses to the lives and property of the people.
The characteristics and common problems of these accidents are obvious, fully revealing that some companies have insufficient and inadequate knowledge of the risk identification of limited space operations; failure to implement the limited space operation approval system and operating procedures; contracting limited space operations to those who do not have safe production conditions The unit is managed in a package, and one package is provided; the necessary protective equipment and emergency equipment are not provided in accordance with the regulations; safety education and training are not in place, the operators habitually violate the rules and regulations, and the blind rescue in emergencies leads to prominent problems such as increased casualties .
The Emergency Management Department emphasized that limited space operations involve mining, chemical, construction, electric power, papermaking, shipbuilding, food processing, catering, municipal engineering, urban gas, sewage treatment, special equipment and other industries, which are high risks that companies can easily ignore. Operation, in addition to the vastly different operating environment and uneven quality of the operating personnel, it is extremely prone to production safety accidents in limited space operations.
All enterprises must strictly implement the main responsibility of safe production, and effectively prevent and control risks in limited space operations.
One is to find out the bottom line in a comprehensive way.
Determine the basic information of the limited amount of space, location, and hazardous and harmful factors in the enterprise, and establish a limited space management ledger.
The second is to improve the rules and regulations.
Establish and improve regulations and safety operating procedures for operation approval in limited space, on-site safety management, etc., and carry out operations in strict accordance with the principle of "ventilation first, inspection, and operation later".
The third is to strengthen subcontracting management.
For projects issued to other units for implementation, the contractor shall have the qualifications or safe production conditions prescribed by the state, and sign an agreement to clarify their respective safety responsibilities.
The fourth is to strengthen safety education.
Strengthen safety training for temporary workers, migrant workers, and personnel of outsourcing units, carry out warning education about accidents in limited space, and strictly prohibit blind rescue.
Fifth, complete protective equipment.
Equipped with necessary gas detection, respiratory protection, fall protection, ventilation, lighting, communication and other equipment for on-site workers.
Sixth, be prepared for emergencies.
Formulate targeted emergency plans, equip with necessary emergency rescue equipment, strengthen emergency plan drills, and prevent the expansion of casualties due to improper rescue.
In order to further promote the units and the public in all regions to deeply learn from the lessons of limited space operation accidents, firmly establish the concept of safety development, promote social safety awareness, tighten and compact various safety responsibilities, effectively prevent and contain limited space operation accidents, and earnestly maintain To improve the safety of people’s lives and property, the Ministry of Emergency Management announced today a number of typical cases of major accidents in limited space operations that have occurred since 2019.
