What kind of accident is this?

It should be considered a safety accident; the blast discs need to be replaced regularly (the typical service life of blast discs is 12–18 months).

It belongs to a safety accident. Preventive measures: Conduct regular inspections and replace pressure relief valves; include this in the routine inspection schedule.

It should be a safety accident. The preventive measures include regularly testing and replacing blast discs, as well as conducting regular inspections during shifts

It belongs to a safety accident. Safety valves have a limited service life, typically 12–18 months. Generally, any accidents such as equipment damage or injuries to personnel that occur during production are considered safety incidents.

It is a safety accident. The preventive measure is to regularly inspect and replace the blast discs.

This is certainly a safety accident. According to Article 154 of the **Regulations on Safety Inspection of Pressure Vessels issued by the Quality and Technical Inspection Bureau: Safety valves should generally be calibrated at least once a year; when it is difficult to remove them for calibration, on-site calibration (in-line calibration) should be employed ； The rupture disc devices should be replaced regularly; those that have exceeded the maximum designed rupture pressure without bursting must be replaced immediately ； Blowout valve devices used under harsh conditions should be replaced annually ； Generally, burst disc devices should be replaced every 2 to 3 years (except where the manufacturer specifies that the service life can be extended). Strengthen inspections, and simply replace the blast discs regularly according to the instructions provided with them.

It is a safety accident; our organization has taken action against a number of people at all levels in connection with this matter – those who needed to write apologies did so, and those who deserved penalties had them imposed on them. The reason for the investigation was sudden weather changes that caused cracking due to the sharp drop in temperature. The question is how to prevent it? If injury to people occurs due to fragmentation before the scheduled inspection and replacement period, how can it be prevented? This post was last edited by I’m quick on 2009-2-16 09:17]

It belongs to a safety accident. Preventive measures: 1. Install clear warning signs in areas where safety valves and explosion-proof devices are located. 2. The staff in this workshop should be aware that when external personnel or employees from other departments carry out work, someone from this workshop must be assigned to supervise them on site. 3. Safety valves need to be regularly calibrated, and explosion-proof devices should be replaced periodically; records should be kept for future reference. 4. Adhere strictly to the principle of \"four no’s\" in accident handling, and strengthen safety education for employees to raise their safety awareness

This is a safety accident. Generally, blast valves need to be inspected regularly to check the safety system. Replace every film cycle. Safety first. :)

It belongs to a safety accident. Preventive measures: 1. Pressure relief valves should be replaced regularly, inspected frequently, and proper records kept. 2. Clear safety warning signs should be installed in the area around the pressure relief valve’s vent. 3. Safety education and technical instructions should be provided to external personnel, and plans should be prepared for potential accidents. 4. During construction, personnel familiar with the site from the same workshop should be on hand to oversee safety; in the event of an emergency, evacuation should be carried out according to the predetermined routes. 5. The principle of \"safety first, prevention foremost\" should be adhered to, and employees should receive safety training in strict accordance with the principle of \"no exceptions\", in order to prevent similar accidents from occurring again.

It’s definitely pulling, and it also hurts people.

Safety accidents: Article 154 of the \"Regulations on Safety Inspection of Pressure Vessels\" stipulates that safety valves should generally be calibrated at least once a year; when it is difficult to remove them for calibration, on-site calibration (in-line calibration) should be employed； The rupture disc devices should be replaced regularly; those that have exceeded the maximum designed rupture pressure without bursting must be replaced immediately ； Blowout valve devices used under harsh conditions should be replaced annually ； Generally, burst disc devices should be replaced every 2 to 3 years (except where the manufacturer specifies that the service life can be extended). 　　 Blowout valves are important safety devices for pressure vessels and pipelines. It can explode under specified temperature and pressure to release pressure, thereby protecting people’s lives and **property. It no longer meets the requirements, so of course it needs to be counted. Prevention: Usage aspects: 1. Use alone. 2. Use in conjunction with a safety valve. 3. If it is not desired for the material to leak out after overpressure occurs, install a safety valve behind the burst disc. 4. If there is a concern that the material may affect the burst disc, another burst disc can be installed behind the safety valve. 5. When the material temperature is low, an isolation diaphragm should be placed at the outlet of the burst disc to prevent atmospheric moisture from freezing on the diaphragm and affecting its performance. 6. Use a torque wrench during installation; hard gaskets should be employed, and care must be taken to ensure that the convex surfaces of the new burst disc (whether positively or negatively curved) are not subjected to stress or impact. 7. The clamp and the burst disc generally provide a hard seal; if the sealing surface of the burst disc is damaged, it must be replaced with a new one. 8. Check the installation direction. 9. If interlocking is required, a sensing device can be added to the burst disc; attention should also be paid to its fatigue characteristics. Management aspects: 1. Place clear warning signs in areas where safety valves, burst discs, and other similar devices are located. 2. Personnel in this workshop should be aware of this, and when external personnel or employees from other departments carry out work, staff from this workshop should be assigned to supervise them on-site. 3. Safety valves need to be regularly calibrated, and burst discs need to be replaced periodically (according to the instructions), with records kept for future reference. 4. Adhere strictly to the principle of \"four no’s\" in accident handling, and strengthen employee safety training to raise their safety awareness

It belongs to a safety accident. Preventive measures: 1. Maintain records and replace them regularly. 2. Those that have burst due to startup pressure must be replaced immediately. 2. Install safety warning signs at the discharge outlets; determine the height of these outlets based on the gas density, and ensure that any gases that can be diluted are discharged into a dilution device. 3. Set up barriers to prevent unauthorized personnel from entering the discharge area. 4. Enhance employee training, including aspects related to emergency response and prevention

If it’s not a safety accident, then what is it? It’s a typical safety accident. Prevention can be achieved through management and technical measures: in terms of management, this involves inspections, regular checks, and safety training; technically, it involves using the latest equipment along with supplementary measures

This must be a safety accident. Firstly, regarding the setting of the burst disc, it is generally set slightly above normal pressure; when the burst disc activates, it indicates that the internal pressure is not within normal limits ； Secondly, the fact that the explosion disc caused employees to lose consciousness after it activated indicates that the vent pipe located at the back of the explosion disc was not properly designed, as no adequate measures were taken to prevent such outcomes after detonation. The vent behind the blast disc should be led to a safe area. Secondly, according to what you described on the 8th floor, this is due to sudden weather changes and rapid cooling that caused the breakage. That means there was an issue with the selection process; it should be selected again.

After reading everyone’s replies, I found it useful and learned a lot*. Upvote!

1. According to Article 154 of the **Regulations on Safety Inspection of Pressure Vessels issued by the Quality and Technical Inspection Bureau: Pressure relief devices must be replaced regularly; those that have not ruptured despite exceeding the maximum designed burst pressure should be replaced immediately； Blowout valve devices used under harsh conditions should be replaced annually ； Generally, burst disc devices should be replaced every 2 to 3 years (except where the manufacturer specifies that the service life can be extended). 2. Factories should strengthen the management of safe operations. 3. Attention should be paid to electrochemical corrosion caused by different metal materials in rupture disks.

I quite agree with the view put forward by floor 16. Due to the limited information provided by the original poster, there are still some questions. 1. Regarding the cause of the rupture of the burst disc, I have some doubts as to whether it was due to changes in weather temperature. Usually, sudden fluctuations in ambient temperature do not easily lead to the failure of a burst disc; rather, it is frequent changes that can cause fatigue and thus result in failure. Meanwhile, even if it is caused by changes in ambient temperature, that remains the direct cause. Does the company have a proper design review system in place when selecting rupture discs? If so, is it being implemented effectively? If it is caused by other reasons, it may also involve issues related to the integrity management of the equipment. 2. Is the selection of the emission outlet reasonable? Will the corresponding design review system and risk management system also be considered? Toxic, flammable, and explosive gases are generally not permitted to be released directly into the atmosphere in design. 3. Does the company have appropriate risk assessment and control systems for operations carried out near the gas venting outlets? Can such risks be identified and controlled? 4. Are CO detection alarms installed at the work site, or do the workers have portable CO alarms? Can it issue an alarm in a timely manner when there is CO gas in the working environment? 5. Are the workers equipped with personal respiratory protection emergency equipment? So as to enable timely and effective evacuation from the site in the event of a CO alarm? Finally, it is recommended that the company also investigate the reasons from its management system to prevent similar accidents from occurring. As for personnel handling, I still have reservations about dealing with the individuals themselves; if anything needs to be done, relevant managers should be given priority.

For devices such as safety valves and blast vents, their exhaust openings should be connected to other containers rather than being allowed to vent directly outside. In addition to regular inspections, it is also necessary to check whether the installation of these blast vents meets the required standards

It constitutes a safety accident; it should also be classified as an accident involving special equipment, and reports must be submitted to both the safety supervision department and the technical supervision department. The rupture discs should be replaced regularly (the typical service life of rupture discs is 12–18 months).
