1. Safety hazards of bad operation habits

　　For all security killers, this killer is the most powerful, and its concealment is also the highest, and it is the most difficult to defeat the index.

　　 It is reported that more than 90% of the operators caused the accidents because they did not operate according to the requirements during the operation.

　　 Installed version (with blanket)

　　 Habit

　　 Generally, there are many printing plates in rotary machines. Operators are accustomed to hanging plates in two or more groups at the same time to save time and improve work efficiency. At the same time, the sheet-fed offset printing machine also has this phenomenon. In order to speed up the progress, and after temporarily installing the version, the master also came to help, that is, one person pressed the version and one person clicked the switch.

  Security risks

　　When installing the version (with blanket), if two or more people operate at the same time, the concentration is slightly inconsistent, the hand slips or unexpected machine failure occurs, it is easy to get your fingers involved, causing personal injury.

  Precaution

　　 (1) The plate-setting work can be operated by one person. Gently pinch the printing plate tail and pad to ensure that the plate is not scratched and the pad is flat.

　　 (2) In case of mistakes or "connected power" when installing the plate, release your hand immediately, do not hold the plate. Since it is a punctual car, it will not cause much loss. If you hold it on, 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

　　 Habit

　　 Due to the need of ink leveling, the operator is accustomed to move the ink shovel back and forth on the ink roller to perform ink leveling, add ink or shovel excess ink from the ink roller.

  Security risks

When the equipment is running at a high speed, such operation is a dangerous operation with many accidents. Once the angle pin of the ink shovel is offset or the ink shovel encounters unevenness on the surface of the ink squeegee, the ink shovel will be drawn into the main ink squeegee Accidents occur between the rubber rollers, ranging from scratching the printing plate or rubber roller, to crushing the blanket or roller, and even causing an accident when the ink shovel is in a hurry.

  Precaution

　　 (1) First of all, you must keep your heels steady, concentrate on the ink shovel, and avoid looking around.

　　 (2) When it is found that the local ink amount of the printed product is not enough and the ink must be refilled manually, the ink shovel in the hand must be firmly held, and the small ink roller is lifted, and the operation is performed after the roller is stopped.

　　 (3) When shoveling ink, the ink shovel should be based on the main ink roller, and should lean on the rubber roller. It should not be suspended. The contact angle between the ink shovel and the ink roller should not be less than 45°.

　　Decontamination

　　 Habit

　　Whether it is a rotary press or a sheet-fed offset press, the phenomenon of sticking of ink skin, rubber rollers, and paper shedding onto the graphic part of the printing plate often occurs, which affects the quality of the product. At this time, operators often use their fingers to remove dirt while the machine is running.

Security risks
　　 This kind of operation is a dangerous operation that violates regulations, and there are many accidents caused by this in printing. When the machine is running at high speed, the operator needs to find the location of the dirty spot and erase it. The available time is quite short, and it can’t be wiped off with force. Only when you start early, you can use strong force to stick it to the plate graphic (or ink roller) Remove the dirty spots. With a few mistakes, it is possible for your fingers to enter the space where the plate cylinder is empty. If it is suspended operation without support, it is likely to bring a hand into the drum and cause a rolling accident.

  Precaution

　　 (1) Check all the safety devices of the machine and the brake mechanism of the main motor regularly every week to ensure that the machine is sensitive, reliable, and promptly repairs if problems are found.

(2) Pay attention to the operation, do not hang in the air. When wiping the dirty spots, the palm must rest on the pull shaft between the plate cylinder and the rubber cylinder, or on the water roller protective safety cover, pay special attention to the palm The strength of the support is greater than the force of the finger to wipe the dirty spot.

　　 (3) If too many dirty spots affect printing, it should be shut down for inspection, and the rubber roller or paper and ink should be replaced in time to fundamentally solve the problem.

　　In daily production, we must establish the safety first thought and cultivate good operating habits, otherwise in the event of an accident, product quality and economic benefits will be impossible to talk about. Therefore, bad operating habits are the biggest killer causing safety hazards.

　　 2 Failure to observe workshop production specifications

　　In fact, this item is similar to the first one, the difference is that this one focuses more on the workshop specifications rather than the operation specifications.

I once heard a netizen say that a security accident occurred in their printing workshop. The printing machine twisted an employee’s arm. The root cause of the accident was that the employee wore slippers to work, but the slippers slipped in order to catch things. , And put his hand into the printing press.

　　 It's a pity that there is a pity for the accident! And for this accident, who should bear the responsibility of the accident?

　　3 Production coordination is not tacit

　　Due to the lack of cooperation with coworkers, a worker pressed the click button when cleaning the rubber cylinder because his companion did not know. As a result, the employee's hand was caught in the printing press.

　　 Of course, such accidents will not be common now. Due to the improvement of the safety performance of the equipment, this kind of accident is also greatly reduced.

　　 4 Safety accidents caused by equipment design defects

　　 Defects in equipment safety design are indispensable reasons for accidents. In the past, due to the inadequate safety design of the old machine, there were many hidden safety hazards, and the work-related injuries caused by the machine also occurred frequently.

　　 In some small printing houses, we often hear news that some paper cutters have cut off one finger. Of course, with the improvement of machinery and equipment, the unilateral problems of the equipment are gradually reduced.

　　 5 Enterprise safety 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 goes beyond individuals and equipment, and is closely related to the entire enterprise and corporate culture.

　　Remember that in a conference on printing quality, the Chinese business executives mentioned the importance of corporate culture. It can be seen that safety training also belongs to corporate culture.

The rate of work-related accidents for companies that conduct regular safety training for employees is much lower than those for companies that do not have a safety system in the workshop. 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 person in charge of these companies also believes that if the employees of the company are injured or injured, 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 kind of accident "it is normal to have bumps and collisions like a car, and any company will appear." Perhaps in his remarks, the common phenomenon in the Chinese printing industry was revealed.

　　 For a long time, printing workers have a poor working environment and low pay, so it is not surprising that the graduates of printing majors change jobs after a short time. After about half a year of learning, I will be a self-skilled worker. In the absence of professional technicians, these small and medium-sized enterprises allow non-professional technicians who work halfway to work, which also reflects the lack of professional skills training and strict management of employees, and the lack of professional qualification certificates for employees. It is unavoidable to run the computer on the next operation.

Although it is only a brief summary of the five points, there are still many incomplete aspects, but it can be considered that the poor safety design of the device itself is the objective cause of the accident, and the irregular operation of the employees is the subjective cause of the accident. Negligence is an indirect and indispensable cause of the accident!

　　Measures to deal with mechanical injury accidents

　　 1. Serious situations such as broken hands and broken fingers

　　 The wounds should be bandaged to stop bleeding, relieve pain, and perform semi-fist-like functional fixation. Apply disinfection or clean dressing to the broken hands and fingers, and avoid immersing the broken fingers in alcohol and other disinfectants to prevent cell deterioration. Place the wrapped broken hands and fingers in a leak-free plastic bag, tie the bag tightly, put ice cubes around the bag, and quickly take the injured to the hospital for rescue.

　　 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 inverting the device. The proper method is to dismantle the equipment parts. If it cannot be removed, dial local 119 to request rescue.

　　 3. A scalp laceration occurred

Rescue the wounded in time, take pain relief and other symptomatic measures; wash the wounded area with normal saline, tightly bandage with sterile gauze cloth, sterile cotton, and press to stop bleeding; use antibiotics, inject anti-tetanus serum to prevent wound infection; Send to hospital for further treatment.

　　 4. The injured person suffered a limb fracture

　　 Try to keep the injured position, medical staff to fix the injured limb, and under the guidance of the correct way to carry, to prevent further aggravation caused by improper rescue methods.

　　 5. Injured people have symptoms of breathing and cardiac arrest

　　Must immediately perform chest compressions or artificial respiration.
