When performing work on presses of the "Sweet" type with the simultaneous management of presses-vulcanizers of lower qualifications - 6th grade.

Many are interested in what kind of work a press-vulcanizer is. This specialist processes rubber products using volcanic hydraulic presses. Moreover, depending on the bit depth, he may be entrusted with presses with electric or steam heating. What is it for?

In general, vulcanization is a chemical process that alters the performance characteristics of rubber. After processing on special equipment, it becomes harder and at the same time elastic.

Employees with low rank are involved in preparing equipment, laying and collecting forms. Masters with a higher grade carry out the process itself, taking into account the regulations and indications of instrumentation. What a press-vulcanizer does at an enterprise depends on its category, qualifications, focus of the company itself and other factors.

Knowledge

An employee, entering a job, must have a good understanding of the technology of the process of pressing products from different types polymers. He is obliged to study the equipment with which he has to work, to know its structure and principle of use. He must also study what types of molds, materials exist, know their composition, properties, and where they are used. Also, his knowledge should include information about state standards and technical conditions for products manufactured by the company where he is employed.

Duties

Job description the press-vulcanizer assumes that this employee is handling complex polymer products. Moreover, depending on the type, special requirements may be put forward for them, including appearance, size, physical and mathematical indicators, pressing, etc. He should be able to press tall, thin-walled products with multiple cavities.

His responsibilities include the preparation of equipment and accessories, including removable signs, fittings and others. The instruction of the press-vulcanizer implies that he preheats the workpieces using high-frequency current. This employee is engaged in the definition and installation of the pressing modes, as well as the screwing of the marks that form the threads, using mechanical devices or, if possible, manually.

Rights

Since the position presupposes the presence of subordinate personnel, the employee has the right to give workers assignments, control the execution of tasks and the quality of work performed. The specialist has the right to request and receive information and documents concerning himself and his subordinate employees.

The press-vulcanizer can interact with other services of the company, get acquainted with the decisions of the management and offer options for correcting the shortcomings identified in the course of the activity, if they are within his competence. He also has the right to report to his superiors on the revealed violations, to propose the recovery or encouragement of the personnel subordinate to him.

A responsibility

The employee is responsible for the poor-quality or untimely performance of the tasks assigned to him or his subordinate. He can be prosecuted if he violated the company's regulations, committed violations of the current legislation and for causing material damage to the company. Also, a press-vulcanizer can be punished for failure to comply with the requirements of technological instructions, violation of fire and electrical safety rules.

He is responsible for the observance by him and his subordinates of the established procedure of production, labor discipline and for the breakdown of tools, equipment and other devices that are assigned to him. He may be held liable if, through his fault or oversight, an accident, accident or other violation occurs.

Labor protection instructions for the press-vulcanizer

Only those workers are allowed to perform work who meet the age standards, in accordance with current legislation, and have undergone a medical examination confirming that they are allowed to perform this type of work. It is also necessary that they undergo training, confirm their theoretical knowledge and practical skills. Before an employee is allowed to independently perform tasks, he undergoes a mandatory internship from 2 to 14 shifts.

Their number depends on the nature of the work performed and the qualifications of the employed worker. The internship process should be supervised by another employee of the company, appointed by the management. Only those who have received an electrical safety group can work with a power tool. Also, employees must periodically undergo a medical examination, in accordance with the procedure established by the Ministry of Health.

Knowledge check

The press-vulcanizer must be tested annually on occupational safety knowledge. In addition, such tests can be arranged if he has not worked for more than six months or moves to the same position in another company. His knowledge can be tested if required by the company management, government supervisory authorities and regulatory agencies. And also if new legal acts are introduced, gross violations of labor protection have been identified or new machinery and equipment have been introduced at the enterprise.

When does the briefing take place?

Presser-vulcanizer must undergo a mandatory instruction on labor protection at the time of employment. Immediately he should be given introductory material, and then the initial clarification of the norms should be carried out at the workplace. He must be re-instructed at least once every six months. It is also necessary if new or revised regulations have been introduced, the technological process, equipment, tools, raw materials, or any other factors affecting labor protection have changed. It should be carried out in case of revealed violations, the requirement of management or control and supervision bodies, as well as during interruptions in work for more than six months.

Knowledge of labor protection

The employee is obliged to study all passports and technical instructions of the equipment with which he has to work. He must also know what kind of danger and harmfulness exists in the workplace. The press-vulcanizer has no right to start work without knowing how to protect himself from unfavorable production factors, including the high temperature of materials, equipment and air, dust and dirt in the working area, as well as high noise levels.

The employee is obliged to study electrical, explosion and fire safety, be able to use fire extinguishing means. The employee must use individual protection, specialized footwear and clothing when performing work. He is also required to be able to provide first aid, comply with all the rules and regulations established at the enterprise.

Labor protection requirements

According to the instructions, the vulcanizer has no right to endanger his life and health, including being in those parts of the workshop that do not belong to his working environment. He must report all accidents to the management with the aim of organizing assistance to the victim, his referral to the medical service center.

He is also obliged to preserve the situation, the condition of the equipment and other details until the arrival of the commission and the investigation of the incident. The only exception is the situation when the situation can lead to an accident or threaten the life of other workers. If an employee detects a malfunction of devices, tools or other devices, he is obliged to report this to the management and not start work until the problem is resolved. These are the basic rules and instructions for the press-vulcanizer.

They can be supplemented or modified within the framework of the current labor legislation... The basis for the change is the requirements of the company, the focus of its activities and other factors. Before starting work, the employee must familiarize himself with all management documentation and job descriptions.
