Mechanical injuries refer to injuries such as compression, collision, impact, shearing, entrapment, entanglement, ejection, cutting, severing, and puncturing caused by the direct contact between moving or stationary parts of mechanical equipment, tools, or workpieces with the human body; these do not include injuries caused by vehicles or lifting equipment
1. Injuries caused by mechanical rotation: Mechanical equipment is composed of many components, some of which rotate while others remain stationary. Rotating parts possess a large amount of kinetic energy during rotation, and if they come into contact with people, it can cause injury. For example, crushing the hand, getting clothes caught in it, or getting long hair entangled in it, and so on. 2. Injuries caused by the movement of machinery: Machinery can cause crush injuries, blows, and other harm to people during its operation. 3. During lifting, it may cause injuries to people, or even death. 4. Electric shocks caused by electrical appliances can result in injuries or even death to people. I think the main points are as mentioned above; please add anything else.
Potential accidents: Mechanical injuries. Hazard factors: Twisting, cutting, crushing, hitting, squeezing, piercing, which can injure the human body. Trigger condition 1: 1. Being hit, cut, pierced, crushed, squeezed, etc. due to carelessness during production inspections or equipment maintenance; 2. Clothing and other items get caught in rotating equipment ; 3. Injury caused by impact from rotating, reciprocating, or sliding objects ; 4. Scratches caused by cutting tools, protruding mechanical parts, burrs on the edges of blanks, or sharp edges of tools and equipment. Conditions for occurrence: The human body comes into contact with moving objects such as those that are rotating or in motion. Trigger condition 2: 1. Lack of concentration during work ; 2. Personal protective equipment not worn correctly ; 3. Illegal operation, consequences of accidents, human injury, hazard level: Grade II, severity: critical. Preventive measures: 1. Maintain concentration while working and pay close attention to your surroundings ; 2. Wear protective equipment properly ; 3. Strictly follow the operating procedures during the work process ; 4. Protective covers should be installed on the rotating parts of the equipment (such as exposed shafts, etc.) ; 5. Protective fences should be installed around areas where dangerous movements take place ; 6. Machinery and equipment should be regularly inspected and maintained to ensure they are in good condition
1. What is mechanical injury? Mechanical injury refers to harm caused by the powerful functions of machinery acting on the human body. 2. What are the characteristics of mechanical injury accidents? Mechanical injury accidents are severe in nature; they can occur through being crushed, squeezed, trampled, run over, killed by flying objects, or worn to death, among other ways. When it is detected that someone has been injured by machinery, although the machine is stopped urgently, the inertia of the equipment can still cause fatal injuries to the victim. 3. What are some of the common mechanical devices that can cause harm to the human body? These include belt conveyors, ball mills, cranes, winches, drying machines, air hammers, lathes, roller machines, sand mixers, screw conveyors, pumps, molding presses, enema machines, crushers, coke pushers, oil presses, vulcanizing machines, unloading machines, centrifuges, mixers, rolling mills, felt spreading machines, and drum screens. 4. What are the main causes of accidents resulting in mechanical injuries? The main causes of accidents that lead to mechanical injuries include: 1) Failure to observe safety measures during the maintenance and inspection of machinery. Severe consequences can arise when people enter equipment such as ball mills for maintenance or inspection tasks without shutting off the power supply, without installing warning signs indicating that the switch must not be turned on, and without having a dedicated person to supervise the process. Some accidents were also caused by misjudgments due to factors such as the action of a timed power switch or temporary power outages at that time. In some cases, even though the equipment was powered off, work was started before the equipment’s inertial motion had completely stopped, which also led to serious consequences. 2) Lack of safety devices. If there are mechanical transmission belts, gearboxes, couplings near the ground, pulleys, flywheels, and other components that could cause injury to human body parts, no proper protective devices are in place ; In addition, areas such as manholes, feed ports, and cage wells lack guardrails and covers, as well as warning signs; if people accidentally come into contact with these areas due to carelessness, accidents can occur. 3) The layout of the power switch is unreasonable; in an emergency, it is not possible to stop the machine immediately ; Another option is to have several mechanical switches placed together, which can easily lead to accidental activation of the switches and result in serious consequences. 4) Self-made or arbitrarily modified mechanical equipment that does not meet safety requirements. 5) Perform tasks such as cleaning, removing jams, and applying belt wax during machine operation. 6) Entering areas where mechanical operations pose risks arbitrarily (sampling, working, passing through, picking up items, etc.). 7) Personnel without the necessary skills to operate machinery taking up positions, or other people tampering with the machinery. 5. Preventive measures against mechanical injury accidents. The preventive measures against mechanical injury accidents include: 1) When maintaining machinery, it is necessary to strictly follow the procedures of turning off the power, placing warning signs indicating that switching back on is prohibited, and assigning a dedicated person to supervise the process. After the machine is powered off, it is necessary to confirm that its inertial motion has been completely eliminated before proceeding with work. After mechanical maintenance is completed, and prior to trial operation, a thorough inspection of the site must be carried out; the switch can only be turned on after confirming that all personnel from the machinery area have been completely evacuated. During maintenance and testing, it is strictly prohibited to have anyone remaining inside the equipment to start it up. 2) Machinery that is in direct and frequent contact with human hands, such as rubber mixing machines, must be equipped with proper emergency braking devices; the location of these braking buttons must be such that operators can reach them at any time within the range of operation of the machinery ; All transmission parts of mechanical equipment must be equipped with reliable protective devices ; All manholes, feeding ports, screw conveyors, and other such components must be equipped with covers, guardrails, and warning signs ; Keep the working environment clean and tidy. 3) The layout of each mechanical switch must be reasonable and must meet two criteria: first, it must facilitate the operator in performing an emergency stop ; Second, avoid accidentally activating other devices. 4) When performing tasks such as cleaning debris from machinery, removing stuck materials, and applying belt wax, it is necessary to follow the procedures of shutting down the machine, turning off the power, and placing warning signs. 5) Unrelated personnel are strictly prohibited from entering areas where mechanical operations pose significant hazards. If someone who is not involved in these operations must enter for some reason, they must first contact the person operating the machinery on duty, and entry will only be permitted if safety measures have been put in place. 6) Personnel operating various machinery must receive professional training, possess basic knowledge of the equipment’s performance, pass relevant examinations, and work with a valid certificate. When working online, it is necessary to operate with care, strictly adhere to relevant rules and regulations, use personal protective equipment properly, and it is strictly prohibited for unqualified persons to operate mechanical equipment.
Mechanical injuries are present in all reports, and the levels are more or less the same; it’s no longer possible to have complete data on them. In my opinion, what the people above have said is all correct, but each case needs to be analyzed on its own terms; it’s not sufficient to conduct a thorough analysis just because mechanical equipment is involved – a targeted approach is necessary. In some cases, there was only minor mechanical damage; the object in question might have simply been scratched, yet it was described as having died from being crushed, squeezed, trampled, or run over – various ways of dying – which scared the company to death. In any case, it’s better to conduct a targeted analysis and remove some of these unnecessary descriptions.
