Safety is the lifeline of laboratories and production operation sites. The painful lessons from the laboratory accident at Chongqing University, the antifreeze leakage accident of the generator set in Shenyang, and the chemical industry park accident in Xiangshui, Yancheng, warn us that even minor safety oversights can lead to catastrophic disasters. This thematic discussion sorts out risks and clarifies prevention and control measures based on these typical cases, with the core of integrating vigilance and execution into the entire process of safety management to build a solid source safety defense line.

Take Cases as Lessons and Dig Deep into the Core Causes of Accidents

The review results of the above three accidents all point to human factors as the core crux: weak safety awareness, lack of safety training, and unfulfilled safety responsibilities. The Xiangshui chemical industry park accident in Yancheng, in particular, was a major safety disaster caused by successive failures in safety management at all levels. Safety management is a systematic work. Laboratories and production sites must strictly abide by safety regulations and implement full-process protection. More importantly, safety considerations should be integrated into the product design stage to avoid potential risks at the root.

Focus on High Risks and Standardize the Management and Control of Hoisting Operations

The standardized management and control of high-risk operation links is the focus of safety work. This discussion focuses on the hoisting operations of 4-meter-high cabinets. Such operations have limited personnel allocation, and a single person cannot complete the auxiliary cabinet holding work, posing multiple hidden dangers such as boom collapse, sling unhooking, and cabinet falling and crushing injuries. Standardized prevention and control measures must be implemented: operators shall hold valid certificates to work, equipment shall undergo annual inspections on time, warning areas shall be set up on site with sufficient auxiliary personnel, walkie-talkies shall be equipped and hoisting drills shall be carried out regularly, and the problem of inconvenient carrying of walkie-talkies shall be solved in a coordinated manner.

Conduct Comprehensive Inspections and Keep a Close Eye on Various Potential Hidden Dangers

In addition to hoisting operations, the operation site also hides risks such as mechanical and vehicle injuries, involving grinding, cutting operations and the operation of special equipment such as forklifts. Even if some special equipment is used infrequently, there must be no paralyzing thoughts. Special safety training shall be carried out for such risks, clarifying operation and on-site avoidance specifications, effectively improving employees' risk identification and emergency prevention capabilities, and avoiding repeating the mistakes of various safety accidents.

Implement Measures in Detail and Consolidate the Foundation of Safety Management

Building a solid safety defense line ultimately starts with details and relies on the implementation of systems. The laboratory accident at Chongqing University once caused risks due to the lack of protective details, which warns us that we must fully equip labor protection articles (PPE) and mandatorily require operators to wear safety shoes in accordance with regulations. Establish a normalized safety publicity and education mechanism through morning meetings, promote the layer-by-layer implementation of safety responsibilities, and carry out targeted training for different types of operations, so that every employee knows the risks, understands prevention and can operate correctly.

Persist in Unremitting Efforts and Stick to the Bottom Line of Safety First

Safety is no trivial matter, and prevention is better than cure. The antifreeze leakage accident of the generator set in Shenyang was caused by lax daily safety management and insufficient detail control, which proves that safety management cannot tolerate the slightest fluke. Only by always maintaining the vigilance of keeping the alarm bell ringing, implementing the requirements of preventing minor problems from escalating into major disasters into every operation link and every management system, attaching great importance ideologically and strictly implementing in action, can we effectively avoid safety accidents and protect the safety and stability of the operation site.
