It doesn't matter if the security officer isn't here, there's nothing wrong with it. Once something goes wrong, you must first be labeled as illegal operation. Even if you have a hot work permit, you are still responsible for illegal operation, not to mention not having a permit. You have to bear all the responsibilities. Welders in chemical enterprises are really dangerous. There was an accident in my former factory. Because the analyst is a woman, she didn't climb to the tank mouth to take samples, but took an environmental sample around her. Results The sulfuric acid tank exploded and three people died. The system is very strict, three-level hot work. In the end, more than 2,000 enterprises announced their dissolution. What's the use of top 500 chemical companies in China? The slogan written in the workshop, this big and that big, no one is fatal! So, brother, you must be careful when doing welding in chemical enterprises. Flammable, explosive and toxic, this is no joke.
