【Sea River Safety Discussion】Hidden Dangers Around Us – Distribution room doors designed to open inward

Thread Content

Walk every day, and you need not fear thousands of miles； Do it often, and you won’t fear a thousand things. Learn one safety in production knowledge point every day, continuously strengthen memory, and improve professional skills in safety in production. As a worker, the more vigilant you are, the greater your chances of survival ； As a business manager, more strictness means less risk. Only by treating every detail with professionalism can the safety goal of \"zero accidents\" be truly achieved. Safety is never a \"choice question\" but a \"must-answer question.\" There is no such thing as “more or less” when it comes to safety; only “100%”. A little more careful inspection today means fewer risks of accidents tomorrow. Security management is never a matter of focusing on the big issues while ignoring the small ones. The significance of identifying potential hazards lies in turning \"invisible risks\" into \"visible actions for correction.\" We firmly believe that every improvement in safety awareness and every enhancement in protective capabilities serves to build a stronger shield for lives and ensure safety for businesses. Keep hidden dangers in sight and have safety by your side at all times! --------------------------------------------------------------------- All members of the community are welcome to participate in the discussion and share information on this thread: [HaiChuan Safety Discussion] – A compilation of potential hazards around us. https://bbs.hcbbs.com/thread-5705518-1-1.html HaiChuan becomes even better with you here! ------------------------------------------------------------------------------------------------------ Inspection basis 1: \"Design Code for Substations of 20 kV and Below\" GB50053-2013. Specific requirements of the regulations: Article 6.2.2: The doors of transformer rooms, distribution rooms, and capacitor rooms should open outward. When there are doors between adjacent switchgear rooms, bidirectional spring doors made of non-combustible materials should be used. Proper operation: The doors of the transformer room, distribution room, and capacitor room should open outward. When there are doors between adjacent switchgear rooms, bidirectional spring doors made of non-combustible materials should be used. ———————————— Knowledge expansion: The reason why doors in transformer rooms, distribution rooms, and capacitor rooms are required to open outward is to ensure safe emergency evacuation, prevent the spread of fire, and facilitate both daily operations and fire separation – addressing the dual requirements of electrical safety and building fire protection. 🔵Reasons for doors opening outward (transformer room / distribution room / capacitor room) 👉Priority is given to emergency evacuation. In the event of a short circuit, fire, or explosion in the electrical room, those inside need to escape quickly. Opening outward prevents overcrowding inside, equipment from toppling over, and smoke pressure from blocking the door, ensuring it can be opened smoothly. General principle in line with all electrical and fire safety codes: Evacuation doors must open in the direction of evacuation. 👉 Prevent backpressure from smoke/fire: During a fire, high-temperature and high-pressure smoke is generated inside; doors that open outward can be pushed open by this pressure, facilitating smoke evacuation and escape ； When opening inward, it is prone to getting locked by pressure. 👉Easy equipment handling and maintenance: The doors open outward, leaving no space inside, which facilitates the entry and exit of large equipment such as transformers and switchgear, as well as on-site operations.
