Fire knowledge lecture

Instructor Xue from the Suzhou Fire Protection Center brought a wonderful lecture on fire protection knowledge. Instructor Xue started from the Xiangshui accident in Jiangsu and pointed out that fire safety is no trivial matter. Regarding the use of dry powder fire extinguishers that everyone is familiar with, Instructor Xue made a supplement, pointing out that before the traditional four-step method of "lifting, pulling, pulling, and pressing", there are also the appearance of solder joints, damage inspection and air pressure inspection of the fire extinguisher, as well as the use of Shake up and down three times before to disperse any dry powder that may form agglomerates, etc. The well-illustrated, in-depth explanations made the security officers present benefit a lot.
