In the production and construction sites, leakage is unavoidable, and even no matter how careful and cautious, there will be accidents. Especially for some substances that are prone to leakage and pollution, we need to take adequate precautions and preparations in advance. Untimely and unprofessional handling after the leakage occurs will not only affect the cleanliness of the working environment, cause safety accidents such as falls and fires, but also cause pollution to the working environment (such as dangerous chemical liquids flowing into the sewer) seriously endangering people's lives.
