Brief introduction of electrical accidents

  On January 2, a personal injury accident occurred in the Hengnan (Duiziling) 220kV transmission and transformation line construction project of the State Grid Co., Ltd. Hunan Hengyang Power Supply Company, and 5 people were killed.

The professional subcontractor of Hunan Power Transmission and Transformation Engineering Co., Ltd., the general contractor, Hunan Silian Electric Power Construction Company During the construction of the foundation of G30 tower, an operator entered the 13.2m deep and 2m diameter foundation pit to bind and fix the detection tube Asphyxiation occurred at that time, and then another 4 workers entered the foundation pit in turn and also suffered suffocation. Five people died after the hospital rescue failed.

  2.7 On 8th, a personal injury accident occurred in the construction project of Shengli Power Plant of Xilin Gol Thermal Power Co., Ltd. of China Huaneng Group Co., Ltd. One person died.

The construction unit Heilongjiang Huaneng Electric Power Technology Co., Ltd., a professional subcontractor, Heilongjiang Construction Installation Group Co., Ltd. When the workers of Heilongjiang Construction Installation Group Co., Ltd. installed the spring support on the left side of the No. 2 furnace and No. 8 coal mill, the spring support and hanger slipped and hit the work platform, causing work A construction worker on the platform fell from 20 meters to the 15.5 meters platform, and died after rescue.

  On March 24, a personal injury accident occurred in the construction project of Shengli Power Plant of Shengli Energy Branch of National Energy Group China Shenhua Energy Co., Ltd. One person died.

The labor service subcontractor of the professional subcontractor Anhui Electric Power Construction Second Engineering Co., Ltd. A construction worker from Anhui Hanjin Construction Engineering Co., Ltd. was dropped by a foot at 12.95 meters when cleaning the outside of the scaffolding on the outer wall of the desulfurization complex The hand tube was hit and died after rescue.

  On July 25, a personal injury accident occurred in Fukang Thermal Power Co., Ltd. in Meihekou City, Jilin Province, which belongs to SDIC Bio-Jilin Co., Ltd., and one person died.

The staff of Fukang Thermal Power Co., Ltd. went to the water source to close the valve of No. 3 well according to the instructions. After wearing a long-tube respirator, a downhole operator suddenly fell to the bottom of the well while operating the valve, and died after being rescued by the hospital.

  The National Energy Administration pointed out that the death toll in July increased by 2 compared with the same period last year, and a large personal accident occurred due to insufficient management of limited space, inadequate safety measures, and unreasonable emergency rescue. The lessons were extremely profound and exposed the owners, The general contractor, construction, supervision and other units have unclear identification of risks in key dangerous operations such as deep foundation pits and limited spaces, poor process control, and training and education.

In response to the July accident and the focus of power safety supervision in the next phase, the following preventive measures are proposed.

  The first is to strengthen on-site safety management and hidden danger investigation and management for high-risk operations such as limited space.

Power companies should strengthen the management of high-risk operations such as limited space, strengthen the investigation and management of safety risks and hidden dangers in important links, key parts, key areas, and strengthen high-altitude operations, tunnel excavation, lifting operations, use of scaffolding, and tall formwork construction. Risk operation management and control to ensure the safety of the operation site.

Especially for limited space operations, targeted special safety training should be carried out.

Strengthen the management of the limited space operation construction plan, strictly implement the limited space operation approval requirements, and check the limited space protection materials, emergency material configuration and the implementation of safety measures.

Strengthen safety technical clarifications before operation, set up full-time guardians, and do a good job in communication, accident prediction, emergency rescue and other related work. It is necessary to "ventilate first, then detect, and then work", and it is strictly forbidden to enter the limited space without authorization.

  The second is to cultivate good safety behaviors and habits of operators.

All power companies should study and develop the good behaviors of “talking about tasks, risks, and measures” of operators before starting work.

When the operator arrives at the site, he first checks the work site, observes the work environment, and then recalls the safety risks and measures. They can work only when they are clear-headed and focused.

It is necessary to strengthen daily accident emergency response plan drills, and to rescue accidents scientifically and rationally. When the method is not mastered, the strength is insufficient, and the conditions are not available, blind rescue is strictly prohibited to avoid the expansion of the accident.
