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\" – it’s an \"obligatory 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 barrier 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 their insights on this thread: 【HaiChuan Safety Discussion】A collection of potential hazards around us: https://bbs.hcbbs.com/thread-5705518-1-1.html. HaiChuan becomes even better with you here! ------------------------------------------------------------------------------------------------------ The two doors of the blast-proof control room (central control room) can be opened simultaneously; there is no interlock mechanism that prevents the inner and outer doors from being opened at the same time. Reference 1: \"Code for Blast Resistance Design of Petrochemical Buildings\" (GB/T50779-2022). Specific regulatory requirements: 5.2.2 The blast resistance doors used in blast-resistant buildings shall comply with the following provisions: 2 The structure and performance of the blast resistance doors in access passages shall meet the following requirements: 4) The interior and exterior doors in isolated rooms shall have an interlock mechanism that prevents them from opening simultaneously, and this interlock shall be automatically disabled in the event of a fire. Reason analysis: Why should the inner door and the outer door have different interlocking functions for opening? The interlock that prevents the interior and exterior doors from being opened simultaneously before isolation is in place to ensure that one door remains closed at all times in the event of an explosion, gas leak, or other accidents, thereby creating a buffer zone that stops shock waves and flammable or toxic gases from reaching the internal safe areas ； Disabling interlocks during a fire is intended to ensure the emergency evacuation of personnel, addressing both the needs for accident prevention and emergency escape, in line with the safety design principles for high-risk environments in the petrochemical industry.
