【Sea and River Safety Discussion】Hidden Dangers Around Us – The absence of emergency shut-off valves on loading and unloading pipelines, as well as valve controls that are not easy to operate

Thread Content

Keep walking every day, and no distance is too great； 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 fewer risks. 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 ensure safety is always with us! --------------------------------------------------------------------- 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! ------------------------------------------------------------------------------------------------------ Basis for identifying these hazards: According to the \"Design Code for Automation Systems in Petrochemical Tank Areas\" (SHT 3184-2017), 5.4.1.13: Emergency shut-off valves used to interlock and cut off feed should be equipped with on-site manual shutdown buttons or switches outside the fire-hazardous area, so that they can be operated manually in emergency situations. Article 6.4.1.2 of the \"Fire Protection Standards for Engineering Design of Fine Chemical Enterprises\" (GB51283-2020): In the absence of a buffer tank, an emergency shut-off valve that is easy to operate should be installed on the loading and unloading pipelines at a distance of 10 m from the loading/unloading crane positions. Article 6.4.1, Clause 4 of the \"Code for Fire Protection Design of Petrochemical Enterprises\" (GB50160-2008(2018 edition)): An easily operable emergency shut-off valve shall be installed on the inlet pipes for flammable liquids (excluding lubricating oils), at a distance of more than 10 m from the edge of the loading dock ； 7.2.15: For equipment handling liquefied hydrocarbons and flammable liquids with an operating temperature equal to or above their auto-ignition point, a shut-off valve shall be installed on the inlet pipeline leading to the pump, near the base of the equipment. When the volume of the equipment exceeds 40 m3 and the distance between it and the pump is less than 15 m, this shut-off valve must be a remotely operated valve with a manual function; the control button for this remotely operated valve shall be located at a distance of no less than 15 m from the pump. Primary risk: In the event of an emergency, personnel on site can close the valves immediately to prevent the expansion of the leakage.
