Regarding the seven major types of accidents involving special equipment

Recently, while preparing a safety assessment report for elevators and cranes, I encountered similar problems. Types of elevator accidents can be classified, based on the location of the system where the accident occurs, into door system accidents, top or bottom collision accidents, and other types related to the usage aspects of the elevator. I classify it as: fall from height (fall accidents account for a large proportion of accidents involving elevator door systems). ), mechanical injuries (accidents that occur when walking on stairs or slides with the hall doors open also happen from time to time), electric shock, object strikes, and fires. Cranes: electric shock, fire, mechanical injuries, falls from height, object strikes, lifting injuries, noise and vibration. Pressure-related injuries: boiler explosions, vessel explosions, other explosions, object strikes, electric shocks, falls from heights, poisoning and asphyxiation, other injuries. According to the national standard GB6441-86 \"Classification of Accidents Involving Enterprise Employees,\" accident categories are divided into 20 types. The specific categories are as follows: (1) Object strikes, (2) Vehicle injuries, (3) Mechanical injuries, (4) Lifting injuries, (5) Electric shock, (6) Drowning, (7) Burns, (8) Fires, (9) Falls from heights, (10) Collapses, (11) Roof/rockfall accidents, (12) Water inrush, (13) Blasting, (14) Gas explosions, (15) **Explosions, (16) Boiler explosions, (17) Container explosions, (18) Other explosions, (19) Poisoning and asphyxiation, (20) Other injuries. The above is provided by just one source and is for reference only.

Regarding the classification and characterization of accidents involving special equipment, it is clearly specified in Article 4 of Order No. 2 issued by the General Administration for Quality Supervision, Inspection and Quarantine in 2001, namely the \"Regulations on the Handling of Accidents Involving Boilers, Pressure Vessels, Pressure Pipelines and Other Special Equipment\"； 2. Articles 61 to 64 of the revised Regulations on the Safety Supervision of Special Equipment, which will come into effect on May 1 this year, also provide clear provisions. The common causes of accidents during the operation of pressure vessels and pressure pipelines are generally categorized as follows: 1. Illegal operations, 2. Operational errors, 3. Inadequate maintenance, 4. Manufacturing defects, 5. Corrosion by the medium. The forms of failure of pressure vessels and pressure pipelines mainly include: 1. Ductile fracture, 2. Brittle fracture, 3. Fatigue fracture, 4. Corrosion-induced fracture, 5. Creep fracture. For reference!

It’s somewhat similar to the information collected on the 2nd floor, but regarding elevators, I think their summary is better. As for pressure-bearing components, no matter what they are, if an explosion occurs, there’s no need for further classification. Also, why does everyone add electric shock as well? Especially for pressure-bearing equipment, electric shock doesn’t fall under the category of special equipment accidents, right? Moreover, mechanical injury seems to be too general. For the third floor, should we focus mainly on the reasons? Can we draw conclusions from the accident phenomena themselves to see if it’s possible to effectively summarize various accidents involving special equipment? Strive to ensure no omissions, no repetitions, and no overlaps.

Please help discuss this – which fellow sailor has ever organized these things? Thank you!
