Behind the frequent printing safety accidents

the main reasons for the frequent printing safety accidents are caused by non-standard operation and inadequate management, so printing enterprises must have a long-term safety accident prevention mechanism

in recent years, printing enterprises have experienced frequent personal accidents, which not only hurt the physical and mental interests of employees, but also affected the normal production and operation of the enterprise and the image of the enterprise. " The phenomenon of "bloody coal" has attracted the general attention of the government and society, and a series of measures have been issued. We in the EPN community should learn a lesson from it, be alert as soon as possible, and take timely countermeasures to prevent the "ant nest" from becoming a disaster, so as to avoid the "bloody print" also becoming a phenomenon

printing safety accidents occur frequently

reasonably speaking, printing enterprises are not as dangerous as mining enterprises, and they are usually not likely to have serious collective casualties. But why do general personal disability accidents still occur from time to time, and sometimes even fatal events? 7 the key lies in the inadequate safety awareness and education, the imperfect prevention mechanism, and the irregular implementation and inspection of the system. 8 The pendulum has obstacles in the lifting process

with the progress of technology, the manual labor of printing enterprises is gradually reduced. There are more and more printing equipment running at high speed. Accordingly, there are more and more dangers brought by printing equipment of printing enterprises, hidden dangers of fire safety, hidden dangers brought by various solvents and other chemicals. Coupled with the increasingly fierce competition in the EPN industry in recent years, foreign-funded and private EPN enterprises have sprung up, state-owned printing enterprises are facing reform and restructuring, the reform of textbook publishing and distribution system, government free textbook bidding, etc. have also brought great impact to printing enterprises, disrupting the normal production arrangement order, the off-season of textbook production EPN enterprises is extended, the peak season is tightened, and many varieties and versions of textbooks are required to be completed in a very limited time, They can only work overtime continuously. Employees are too tired, which is easy to cause accidents and bring long-term adverse effects on physical and mental health. In fact, the most personal accidents in printing enterprises are caused by illegal operations, The following table is the author's statistics of some personal accidents in printing enterprises seen in the media in recent years:

behind the printing safety accidents

the printing industry is also an industry with dense unsafe factors: accidents will occur in large-scale printing machinery and equipment running at high speed: on the cutting equipment of the assembly process and other processes, it is equipped with a sharp knife. Its power can cut thick paper at once. It violates the operating procedures The main raw materials of printing enterprises, such as paper and paperboard, semi-finished book pages, book stickers cartons, finished books and periodicals, which are very likely to cause personal injury, are inflammables. If they are not properly managed, they are very likely to cause fire: ink, gasoline used in printing and post press finishing processes, other solvent cleaning agents, etc. are inflammables. Once they are accidentally on fire, the consequences are unimaginable: some toxic and harmful chemicals are used in various processes of printing and processing, Improper management and use will cause direct or cumulative harm to human body. However, after investigating the causes of some printing safety accidents, the author found that many reasons behind the accidents are man-made

1. Safety hazards of bad operation habits. It is understood that more than 90% of personal accidents are caused by operators who try to save time or rush time and do not operate in accordance with the requirements of the operating procedures with a sense of luck. The common bad habits of printing operation are:

(1) plate loading (blanket loading)

bad operation habits: generally, there are many printing plates on the rotary machine, and the operators are used to hanging plates in two or more groups at the same time, so as to save time and improve work efficiency. At the same time, this phenomenon also exists in the plate loading of the sheet fed offset press. In order to speed up the progress, sometimes the captain also comes to help, that is, one presses the plate and one clicks the switch

potential safety hazard: when installing the version (rubber blanket), if two or more people operate at the same time, their attention is slightly distracted, their hands slip or unexpected machine failure occurs. It is easy to involve their fingers and cause personal injury

preventive measures: one person can operate the plate loading. Gently hold the printing plate trailing tip and pad with hands to ensure that the plate is not scratched and the pad is flat; In case of mistakes or "power connection" during version loading, release your hand immediately and don't hold the printing plate. Because the car is on schedule, there will be no great loss. If you hold it, it will cause other accidents. If you really need to push the printing plate by hand, you can rub some talcum powder on the plate to prevent accidents

(2) shovel ink

bad operation habits: due to the need of ink leveling, the operator is used to holding an ink shovel to stir back and forth on the ink roller to evenly add ink or shovel away the excess ink on the ink roller

the export share to emerging countries will also greatly improve the security risks: when the equipment is running at high speed, such operation habits are prone to safety accidents. Once the angle of the ink shovel is slightly offset or the ink shovel encounters the uneven surface of the inking roller during operation, the ink shovel will be rolled into the main inking roller and the rubber roller and an accident will occur. At first, the printing plate or cot is scratched. At last, the blanket or roller is crushed. Even in an instant, personal accidents are caused by hurry

preventive measures: stand firmly on your heels, concentrate. Hold the ink shovel tightly. Don't look around. When it is found that the local ink volume of the printed product is insufficient and the ink must be added manually, the ink shovel in the hand must be held tightly, and the small ink roller must be lifted. The operation can be carried out after the roller stops stably. When shoveling ink, the ink shovel should rely on the main ink roller and 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

(3) dirt removal

bad operation habits: whether it is a rotary machine or a sheet fed offset press, there are often phenomena of ink or rubber rollers, and paper falling off objects sticking to the graphic part of the printing plate, which affects the product quality. At this time, operators often use their fingers to remove dirt during machine operation

potential safety hazard: this kind of operation belongs to illegal and dangerous operation. There are many accidents caused in printing. When the machine is running at high speed, the operator should find the dirty spot and erase it. A little mistake. Fingers may enter the space of the plate cylinder. If it is a suspended operation without support, it is likely to bring one hand into the drum and cause a hand rolling accident

preventive measures check all safety devices and main motor brake mechanism of the machine regularly every week to ensure that the machine is sensitive and reliable, and repair problems in time. When operating, pay attention and do not operate in the air. When wiping dirty points, the palm must rest on the pull shaft between the plate cylinder and the rubber cylinder. Or on the protective safety cover of the water roller. Pay special attention to that the force supported by the palm is greater than the force wiped by the fingers. If too many dirty spots affect the printing, stop the machine for inspection and replace the rubber roller or paper ink in time to fundamentally solve the problem

(4) tearing rotten paper blocks

bad operation habits: in the process of printing folding (the folding part of the rotary machine or on the folding machine), many operators will habitually stretch out their hands to tear rotten paper or small paper blocks when they find them

potential safety hazard: this operation is very dangerous. General operators always think that they will be very careful, very fast, and no accidents will happen. But many times, accidents happen like this. Light people tear the skin, heavy people cause finger fracture or even amputation

preventive measures: follow the operating procedures. In case of such situations, it is best to stop the machine for treatment. If you don't stop the machine for treatment, you should pay special attention. The operation should be accurate, fast and stable. Once you find it difficult to tear, the first thing you think of should be to protect your own safety. Let go immediately, and never force your fingers to be pulled into the machine. In daily production, we must establish the idea of safety first and cultivate good operating habits, otherwise in case of accidents, product quality and economic benefits will be out of the question. Therefore, bad operating habits are the biggest potential safety hazard

2. do not comply with workshop production specifications. In fact, this one is similar to the first one, but the difference is that this one focuses more on workshop specifications rather than operation specifications. Once an employee's arm was twisted by the printing machine, and the cause of the accident was that the employee wore slippers to operate on the machine. As a result, the slippers slipped. Instinctively, he wanted to grasp something to prevent falling. He reached into the printing machine. There are also accidents caused by violations of rules and regulations, such as wearing high-heeled shoes to operate on the machine, or having long hair not tied into a work cap, and working sleeves not buttoned, which are typical cases of non-compliance with rules and inadequate management assessment. As for the cases of accidents caused by running the machine to warm up by a high-speed machine, or baking wet hair by hot air of the machine, there is no performance of even the minimum safety common sense. Moreover, the development of "new functions" of this kind of "creative" printing equipment is really a little fanciful. It's no wonder if something happens

3. Production cooperation is not tacit. In one case, due to the poor cooperation with the workmates, a worker did not inform his companion in time when cleaning the rubber drum. The companion did not first observe whether someone was operating on the machine or ring the bell for warning. He rashly pressed the car counting button. As a result, the employee's hand was rolled into the printing machine

4. The personal safety management, education and training of the enterprise are not in place. This is particularly important. Most of the above points are subjective reasons for the objective willingness of operators. However, safety management, education and training go beyond individuals and equipment, and are closely related to the entire printing enterprise and the culture of the printing enterprise

safety culture is also an important part of corporate culture. The accident rate of industrial accidents in printing enterprises that carry out regular safety education and training for employees with good safety management at ordinary times is much lower than those enterprises that have no safety system in the workshop

those enterprises that persist in effective safety education, training and in place management of employees are usually domestic first-class printing enterprises. Their products also occupy the medium and high-end market of the printing industry

and more printing enterprises struggling in the medium and low-end printing market. Their survival is still difficult. There is nothing else to consider. 7 for a long time, the printing workers in these enterprises have poor working environment, low treatment, and serious lack of capital, personnel, and energy investment in safety education, training, and management. They can't keep graduates of college and technical secondary school majoring in printing or experienced operators. In the absence of professional technical and operational personnel, these enterprises will inevitably have problems if they let non professional technicians who are "halfway out" or even temporarily recruit personnel who have not carried out necessary technical and safety production training to work on the machine

5. Production orders and safety problems "double prosperity further improves the effectiveness of factor allocation and factor quality". The peak production season of many printing enterprises has also become a period of frequent personal safety accidents. When there is a shortage of manpower in the peak production season, hurry to recruit some temporary workers. And I can't wait for the new employees recruited to be able to immediately put into intense production. Urgent production orders make enterprises only provide simple technical training for those new non-technical employees. Even without training, you can learn while working. It was too late (in fact, it was more of a lack of consciousness) to carry out the necessary personal safety education. I didn't even expect to carry out the personal safety education

6. The "abnormal" brought by the transformation of primary and secondary school textbooks
