The workplace is an organizationally indivisible element of the production process under specific conditions. It is serviced by one or more people, is designed to carry out various operations, and is equipped with appropriate devices and equipment depending on the specifics of the activity. In the Russian Federation, there are certain regulatory requirements for organizing workplaces. Let's take a closer look at them.
Legal aspect
The requirements for organizing the workplace are established in:
- Labor Code of the Russian Federation.
- Legislative acts of the subjects.
- International and state standards.
- Employment contract.
- Collective agreement.
These acts contain rules, procedures, and establish criteria to ensure the preservation of the health and life of people in the course of their professional activities. Compliance with workplace organization requirements is the responsibility of every employer.
Classification
Workplaces are differentiated depending on the degree of automation. In accordance with this criterion, jobs are distinguished:
Organization of the workplace: occupational safety requirements
Areas of professional activity are located outside the zone of movement of mechanisms, containers, goods, and movement of goods. At the same time, convenient monitoring of ongoing processes and management of operations should be ensured. The basic requirements for the organization of workplaces include the requirement to create free space between areas where employees carry out their activities. It is necessary for the free movement of people during operation of the equipment. Occupational safety requirements for the organization of workplaces include the obligation to place them along the technological process. In this case, counter flows should be excluded when moving containers, products, and waste. The path of movement of products should be as short as possible, and employee transitions should be kept to a minimum. The general requirements for the organization of the workplace of a mechanic and other specialists working at the machine, therefore, provide for the establishment of such a state of areas, as well as the distance between them, to ensure the free movement of people and vehicles, normal maintenance, repair and cleaning of equipment.
Position of employees during operations
Requirements for the organization of the workplace include the need to provide sufficient space for the rational placement of additional inventory, containers, and equipment. The area where professional activities are carried out must be convenient for a person. We are also talking about the employee’s postures in which operations are performed. They should not create difficulties for a person. Requirements for the organization of the workplace include provisions for the possibility of performing operations in a sitting position or when alternating standing and sitting positions. This is provided if the activity does not require constant movement. When performing operations in a sitting position, people should be provided with comfortable chairs.
The requirements for organizing a workplace where an employee performs activities while standing include certain parameters of the area. In particular, the width must be at least 600 mm, length - 1600 mm. The space for feet has the following parameters: 530 mm in width, 150 mm in height and depth. The table installed at the workplace should be at a height of 955 mm from the floor. The necessary tools, equipment, and dishes are placed in drawers, wall cabinets, and racks within reach. The key safety requirement for organizing workplaces is to prevent cluttering of passages and areas where production operations are directly carried out with containers and products. Their mutual location and layout should ensure easy access and quick evacuation in case of an emergency. 
Activities of sellers
The following requirements are provided for organizing the workplace of an employee of a trading enterprise:
- The placement of inventory and goods should provide convenience when performing actions. It is necessary to exclude unnecessary transitions, movements of the torso and arms. Inventory and products must be located in permanent, assigned places.
- At the trading area, comfortable chairs or folding seats are installed for relaxation during the absence of customers. It is not allowed to use boxes or other objects for these purposes. There should be a wooden flooring between the wall-mounted equipment and the counter. This is necessary to prevent hypothermia of the feet.
Sanitary requirements have been established for trading areas. When selling food products, there must be containers with special markings (tanks with lids, buckets, etc.). As they are filled, but no more than 2/3, it must be cleaned. Upon completion of work, all tanks and buckets, regardless of how full they are, should be washed with a 1-2 percent soda solution or other detergents.
Packaging, packing, stacking of products
Special chests and tables must be used at workplaces. The dimensions of the equipment must take into account anthropometric parameters. The working surface is located at the height established in GOSTs 12.2.032 and 12.2.033. The premises where flour and flour products are packaged are equipped with a local exhaust hood. Products with a large weight are packaged on high-strength tables. These surfaces should provide containers for materials: paper, boxes, bags, and so on. For stackers-packers performing various operations, the following positions are recommended:
Workplaces of employees who perform operations primarily in a sitting position with limited mobility must be equipped with adjustable footrests, height, and distance from the table and comfortable seats.
Space for cashier-controller
A chair with a lift-and-swivel mechanism is installed at the employee’s workplace. The seat surface should be slightly curved and adjustable in height within 0.4-0.45 m, have a width of 0.42 m and a depth of 0.41 m. The coverings are made of a material that provides low thermal conductivity and the ability to carry out wet cleaning. For convenience when working in a sitting position, the seat is equipped with a footrest. It must have a regulating mechanism for the angle of inclination and height of the support platform. One of the main requirements for ensuring optimal working conditions for cashiers is a high level of illumination. At the same time, sources of direct and reflected glare are excluded from the field of view of workers. The lamps are located directly above the employee’s work area.
Protection of cashiers from criminal attacks
This is ensured by equipping the premises with emergency lighting and installing a panic button. In the process of depositing funds into a banking organization or when transporting them from it, the employer is obliged to provide the employee with security and, if necessary, a car. The cashier and his accompanying persons, as well as the transport driver, are prohibited from:
- Disclose the route of travel and the amount of transported funds.
- Allow unauthorized persons into the vehicle interior.
- Transport money by public or passing transport, as well as carry it on foot.
- Carry out other assignments, be distracted from delivering cash to its destination.

The monitor should be located at a distance of 600-700 mm from the employee’s eyes, taking into account the size of alphanumeric characters and signs.
Additionally
To prevent drafts in rooms located near doors, technological openings, gates, screens or partitions are installed. Preparation of the workplace is carried out at the end of the shift. The employee cleans mechanisms, tools, auxiliary equipment, and equipment. If necessary, wet cleaning is performed.
Conclusion
Until 2013, in accordance with legal requirements, regular certification of workplaces was carried out. It included assessment and verification of compliance with regulations, the quality of equipment in areas where employees carry out their professional activities. Particular attention was paid to enterprises engaged in the field of catering and food trade. Special commissions were created, which first of all checked whether the sanitary requirements for the premises were met. A new procedure has now been introduced. Certification of workplaces has been replaced by an assessment of the conditions for employees to carry out professional activities. This procedure was introduced in 2014. Corresponding amendments were made to the Labor Code.
