Five killers of printing safety production!
Recently, a printing company in Guangdong had a safety accident in which a printing machine crushed a worker’s finger shortly after the start of construction! All major WeChat groups printing colleagues are forwarding reminders! The editor reminds everyone:
There are thousands of roads to get rich,
The first article of safety in production.
Irregular operating equipment,
Two lines of tears for relatives and friends!
Speaking of safety, road safety, but in many cases safety accidents still happen frequently. Here, the editor will share with you the top 5 printing safety killers. I hope everyone will use this as a lesson to make safe production and go home safely!

1 The safety hazards of bad operating habits
For all security assassins, this assassin has the strongest power, and at the same time, it has the highest concealment and is the most difficult to defeat.
It is reported that more than 90% of the operators caused accidents because they did not follow the requirements during the operation.
Installed version (with blanket)
habitual operation
Generally, rotary machines have more printing plates, and operators are accustomed to two or more groups of printing plates at the same time to save time and improve work efficiency. At the same time, sheet-fed offset printing presses also have this phenomenon. In order to speed up the progress, and after the temporary installation of the version, the master also came to help, that is, one person presses the version and the other clicks the switch.
Security risks
When using the version (with a blanket), if two or more people operate at the same time, they may lose concentration, slip their hands or have unexpected machine failures, it is easy to get their fingers involved and cause personal injury.
Precaution
(1) The plate loading work can be operated by one person. Gently pinch the printing plate trailing tip and liner with your hands to ensure that the plate surface is not scratched and the liner is flat.
(2) In the event of a mistake or "connected power" when loading the plate, immediately release your hand and do not hold the plate. Since it is a punctual car, it will not cause much loss. If you hold it tightly, it will cause other accidents.
(3) The situation of each model is different. If you really need to push the printing plate by hand, rub some talcum powder on the plate to prevent accidents.
shovel ink
habitual operation
Due to the need for ink distribution, the operator is used to holding the ink shovel to move back and forth on the ink roller to distribute the ink, add ink or shovel the excess ink on the ink roller.
Security risks
When the equipment is running at high speed, such an operation is a dangerous operation with frequent accidents. Once the ink shovel angle pin is offset or the ink shovel encounters unevenness on the surface of the ink squeegee roller during operation, the ink shovel will be drawn into the main ink squeegee roller and Accidents occur between the rubber rollers, ranging from scratching the printing plate or rubber roller, or crushing the blanket or roller, and even causing personal accidents due to the rush of hands and feet at the moment of pulling the ink shovel.
Precaution
(1) First, stand firm on your heels, concentrate, hold the ink shovel tightly, and avoid looking around.
(2) When it is found that the ink volume of the printed product is not enough and the ink must be added manually, the ink spatula in the hand must be held tightly, and the small ink roller must be lifted, and the operation will be performed after the roller has stopped.
(3) When shoveling ink, the ink shovel should be backed by the main ink roller, leaning on the rubber roller, and can not be suspended. The contact angle between the ink shovel and the ink roller should not be less than 45°.
clean up
habitual operation
Whether it is a web press or a sheet-fed offset press, the ink skin, rubber roller, and paper fall off often stick to the graphic part of the printing plate, which affects the quality of the product. At this time, the operator often removes dirt with his fingers while the machine is running.
Security risks
This kind of operation is a dangerous operation that violates regulations, and it causes more accidents in printing. When the machine is running at a high speed, the operator can find the location of the dirty spot and erase it. The available time is quite short, and the force can not be wiped off. Only early and strong can stick the graphics (or ink roller) on the printing plate. Remove the dirty spots. If you make a mistake, your fingers may enter the empty space of the plate cylinder. If it is suspended operation without support, it is very likely that one hand will be brought into the drum, which may cause a hand rolling accident.
Precaution
(1) Regularly check all the safety devices of the machine and the main motor brake mechanism every week to ensure that the machine is sensitive and reliable, and repairs when problems are found.
(2) Attention must be paid during operation, and do not operate in the air. When wiping dirty spots, the palm of your hand must be leaned on the pull shaft between the plate cylinder and the blanket cylinder, or leaned on the water roller protective safety cover. Pay special attention to the palm of your hand. The force of the support is greater than the force of the finger to wipe the dirty spot.
(3) If there are too many dirty spots that affect printing, stop the machine for inspection, and replace the rubber roller or paper and ink in time to solve the problem fundamentally.
In daily production, we must establish the idea of safety first and cultivate good operating habits, otherwise, in the event of an accident, everything such as product quality and economic benefits will be out of the question. Therefore, poor operating habits are the biggest killer of potential safety hazards.
2 Non-compliance with workshop production specifications
In fact, this item is similar to the first one, the difference is that this one focuses more on workshop specifications rather than operating specifications.
A netizen once heard that there was a safety accident in their printing workshop. The printing press twisted an employee’s arm. The root cause of the accident was that the employee wore slippers to work. As a result, the slippers slipped in order to catch something. , He put his hand into the printing press.
It is a pity that is a pitiful accident! And for this kind of accident, who should bear the responsibility for the accident?
3 Production coordination is not tacit enough
Due to the inadequate cooperation with the workers, a worker pressed the car button when his companion did not know when cleaning the blanket cylinder. As a result, the worker's hand was caught in the printing press.
Of course, such accidents are not common now. Due to the improvement of equipment safety performance, such accidents are also greatly reduced.
4 Safety accidents caused by equipment design defects
The defect of the safety design of the equipment is the indispensable cause of the accident. Due to the inadequate safety design of old machines in the past, there are many hidden safety hazards, and work-related injuries caused by machines have also occurred frequently.
In some small printing factories, we often hear the news that some paper cutters have their fingers cut off. Of course, with the improvement of machinery and equipment, unilateral problems due to equipment are gradually decreasing.
5 Corporate security training is not in place
Although this point is ranked fifth, it should be said that this point is the most important of the above five points. Most of the above four points are objective reasons and operator's subjective reasons, and this point transcends individuals and equipment, and is closely related to the entire enterprise and corporate culture.
I remember that in a meeting about printing quality, the Chinese business executives mentioned the importance of corporate culture. It can be seen that, of course, safety training also belongs to the corporate culture.
Companies that provide employees with regular safety training have a much lower rate of work-related accidents than those companies that do not have a safety system in their workshops. At the same time, most of these companies that insist on safety training for employees are domestic first-class printing companies. At the same time, the relevant persons in charge of these companies also believe that if employees of the company experience work-related injuries, a large part of the responsibility should be borne by the company.
In response to this type of accident, some printing business owners believe that this type of accident "is normal for collisions like driving a car, and it will happen to any company." Perhaps his words indicate a common phenomenon in China's printing industry.
For a long time, printing workers have had poor working conditions and low salaries, so it is not surprising that printing college graduates change jobs within a short period of time. After about half a year of learning, I will be able to do it by myself, and I will be a seasoned worker. In the absence of professional technicians, these small and medium-sized enterprises have allowed non-professional technicians to work "half-way". This also reflects the lack of professional skills training for employees, lack of strict management, and the fact that employees have not obtained professional qualification certificates. It is inevitable that there will be problems when the computer is operated immediately after the download.
Although it is only a brief summary of five points, there are still many incomplete areas, but it can be considered that the poor safety design of the equipment itself is the objective cause of the accident, and the irregular operation of the staff is the subjective cause of the accident, and the enterprise is educating on safe production. His negligence is the indispensable indirect cause of the accident!
Mechanical injury accident handling measures
1. Serious situations such as severed hands or fingers
The wound of the wounded should be bandaged to stop bleeding, relieve pain, and be fixed in a half-fist-like function. Apply disinfection or clean dressings to severed hands and fingers. Avoid immersing severed fingers in alcohol or other disinfectant to prevent cell deterioration. Put the wrapped severed hands and fingers in a leak-free plastic bag, tie the mouth of the bag tightly, put ice cubes around the bag, and rush to the hospital with the injured.
2. Limb involvement equipment
The power must be cut off immediately. If the limb is still stuck in the device, the limb cannot be removed by turning the device upside down. The proper method is to dismantle the parts of the equipment. If the parts cannot be dismantled, call the local 119 for rescue.
3. Scalp laceration occurred
Rescue the injured in time, take pain relief and other symptomatic measures; wash the injured area with normal saline, wrap it tightly with sterile gauze and sterile cotton, and compress it to stop bleeding; use antibiotics and inject anti-tetanus serum to prevent wound infection; Sent to the hospital for further treatment.
4. The injured person has a limb fracture
The injured position should be maintained as much as possible, and the injured limb should be fixed by medical personnel, and the correct method should be used to lift and transport under their guidance to prevent the injury from further aggravating due to improper rescue methods.
5. The injured person has symptoms of respiratory and heart arrest
Chest compressions or artificial respiration must be performed immediately.
