Do a good job in special equipment safety management and standardization management to ensure safety [Special Equipment Safety Management and Standardization] summary post! Welcome to communicate as we continue to update! ! ! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=5718553( Source: Haichuan Chemical Forum (Huahaichuanliu hcbbs)) Welcome everyone to participate in the exchange and discussion--------------------------------------------------------- November 28, 2024, * * The "Guidelines for Determination of Major Accident Hazards of Special Equipment" (GB 45067-2024) were released and will be officially implemented on December 1, 2024. someone may ask: “It’s just a standard. Is it necessary to be so nervous? ”Very necessary! This standard is a "life and death line" drawn for us. I used to think that the equipment could be used just fine with a few glitches, but not anymore. It’s clearly written in the standards: As long as any of the following situations occurs, it is a "major accident hazard". Once found out, they will be fined for work suspension at the least, and - everyone knows it in the worst case.: It may result in loss of life, but also legal liability. In order to make it easier for everyone to understand and remember, I have "translated" the standards into vernacular, and we will "clear mines" one by one. The first line of life and death: The following four situations are the general red line (whoever touches them will have an accident). As long as they are related, they will be directly judged as major hidden dangers without discussion.: “The "black house" equipment is still in use: Manufactured without a production license due to safety issues * * Those that have been explicitly ordered to be eliminated, have been scrapped or have reached the conditions for scrapping. “"Sick" equipment is still running: If the equipment has been in an accident and is continued to be used without a thorough inspection and complete repairs - this is absolutely not okay. “Working without a certificate: Supervisory inspections that should be carried out according to regulations are not done, or the equipment fails to pass the inspection and is still in use. “"Out of bounds" operation: Used beyond specified parameters and ranges (such as a small horse-drawn cart). The second line of life and death: Boiler (be careful of its "explosive temper") Once something goes wrong with the boiler, it will be a big deal. In addition to the universal red line, boilers also have these "Achilles heel"”: Failed physical examination: If the conclusion of the periodic inspection is "not meeting the requirements", it must be stopped. Became "blind?" son”: The thermal instrument is damaged or the control power supply is interrupted, resulting in the inability to see the pressure and temperature, and unable to adjust it - it is equivalent to a blind man riding a blind horse. No more "brakes"”: Safety valve (bursting disc) missing or damaged ; System alarm device is damaged ; Interlock protection device is damaged ; The flameout protection device is damaged. As long as one of these life-saving devices fails, it will be a major hidden danger. Pipe "leak"”: The main steam and water pipes of the power station boiler or the pipes within the boiler are leaking or ruptured. The third line of life and death: Pressure vessels and pipelines (don’t think of them as “bombs”), whether they are fixed storage tanks, mobile tankers, or gas pipelines: Failed physical examination: The inspection conclusion is "does not meet the requirements". Modify and use indiscriminately: Changing a fixed pressure vessel to a mobile one is a big no-no. Safety attachment failure: Safety valves, bursting discs, emergency shut-off devices - the lack or failure of these last lines of defense is a major hidden danger. special equipment: The interlocking device of the quick-opening pressure vessel is damaged ; The oxygen chamber grounding device or safety interlock is damaged. The fourth line of life and death: In the filling process (be sure not to make the wrong filling), brothers who are engaged in filling mobile pressure vessels or gas cylinders, please pay attention.: Filling without a license: You dare to refill without a license. Wrong media loaded: If a gas cylinder is filled with the wrong medium (for example, an oxygen cylinder is filled with hydrogen), it will explode. emergency cut-off failure: The emergency cut-off device on the filling equipment is damaged and is still in use. The fifth line of life and death: Elevators (don’t let people hang in the air) Elevators are the most common special equipment. These types of problems must not occur: Failed physical examination: The conclusion of periodic inspection is "unqualified". door lock short circuit: Short-circuiting the door lock safety circuit (commonly known as "sealing the door") is the number one cause of elevator accidents. Speed limiter failure: The speed limiter and safety gear linkage test failed, and the elevator could not stop once it fell. Hidden dangers of escalators: Emergency stop switch is missing or damaged ; Or there are obstacles next to the handrails but no protective baffles are installed (it is easy to pinch people). The sixth line of life and death: Hoisting machinery (don’t hit anyone), cranes and cranes on the construction site, these issues must be checked: Taking up the job without a physical examination: Without first inspection. Failed physical examination: The conclusion of periodic inspection is "unqualified". Emergency stop failure: The emergency stop switch is missing or damaged. Overload protection failure: Lifting weight limiter, lifting moment limiter, anti-fall safety device - these are missing or damaged, which is a major hidden danger. Windproof failure: For rail-mounted cranes operating outdoors, the wind-resistant anti-skid device is damaged (be careful of being blown away by the wind). The seventh line of life and death: Passenger ropeway & large amusement facilities engaged in tourism? Friends in the industry come here, this is the lifeline for tourists: Failed physical examination: The inspection conclusion is "unqualified" or "re-inspection unqualified". Emergency stop failure: The emergency stop switches in the control room, platform, and machine room are damaged. The door is not locked or damaged: The door locks of gondolas, gondolas, bus doors, and cockpits are unreliable and are still in operation. Restraint failure: Seat belts, safety bars, and safety bars are damaged (tourists will be thrown out). Cracks in key components: The main stress-bearing parts and welds have cracks or serious deformation. Electrical short circuit: Directly short-circuiting the safety loop to continue operation after a fault occurs - this is a joke on human life. Auxiliary machines and backup power supplies cannot operate. The braking device, limiting device, anti-collision and buffering device, anti-retrograde device, and speed limiting device are missing or invalid. The eighth line of life and death: Special motor vehicles on site (forklifts, sightseeing cars) Forklifts in factories, sightseeing cars in scenic spots: Failed physical examination: The conclusion of periodic inspection is "unqualified". Failure after power outage: The power emergency shut-off device of the electric vehicle is damaged. Brake failure: The service brake and parking brake are damaged. Connection failure: The traction connection device of the sightseeing train was damaged. Climb over limit: The sightseeing bus is still running even if it exceeds the specified maximum driving gradient.
