In HSE management, there is a very practical management tool called security incident experience feedback, that is, the establishment of a “safety warning card” to extensively collect and organize internal and external security incidents in the system, and formulate preventive and pre-control measures to prevent the repetition of similar incidents happen.The “safety warning card” is short and concise, which is convenient for the majority of electricians to read and circulate. It can also be pasted on the wall according to the requirements of the government and enterprise management to warn more electrical workers, and improve workers’ safety awareness in a subtle way..Thanks to the “explosive” development of the Internet and WeChat, thanks to many electrician friends who selflessly shared, we can get many accident cases as soon as possible.When we see an accident case or an accident report, what we see is often a “long story” of thousands of words, in which the essence and spirit are actually just a few words..We can read more repeatedly, “read the book thin and more refined”, and make a warning card according to the accident process, the analysis of the cause of the accident, and the experience feedback (see attached table 1), with pictures and explanations, the so-called “Safety incident experience feedback” and “publication”, can also be used as training materials for publicity and learning, and can also be summarized and bound into a book, read and learn at any time, it is a good training learning card, I hope everyone likes it.The above are some of my personal training and learning experience. Since the “safety warning card” is being promoted and applied, it is inevitable that there will be many deficiencies. I hope you can comment on it..I hope everyone can actively make suggestions and suggestions to make progress and improve together. “Electrician safety is everyone’s responsibility.” I hope that tragedies will not be staged..Safety alert card of a power generation company in Ningxia “8.25” minor personal injury and unit trip accident 1.
