Passageways in public buildings on the path of movement of

millimeters)

The width of the traffic lane of the communication passage in the cleanliness of both the building and the site should be at least 1.5 m when the wheelchair is moving in one direction, and at least 1.8 m when oncoming traffic. Approaches to various equipment and furniture used by visitors with limited mobility should have a width of at least 0.9 m. The dimensions of the space for maneuvering wheelchairs when turning at 90° must be at least 1.3 × 1.3 m, for turning at 180° — 1.3 × 1.4 m, for turning at 360° - 1.4 × 1.4 m. In dead-end corridors, it is necessary to ensure the possibility of a full turn of the wheelchair with a turn radius of at least 0.7 m. The depth of the space for maneuvering the wheelchair in front of the door when opening "from yourself" should be at least 1.2 m, and when opening "to yourself"-at least 1.5 m. The height of the corridors along their entire length and width should be at least 2.1 m in light. The premises, areas and service locations visited by the MGN should generally be located at the level closest to the ground surface. Stairs should be duplicated by ramps or lifting devices. Elevator cab designed for use a wheelchair user with an accompanying person must have an internal dimension of at least 1.7 m wide and 1.5 m deep, and a doorway width of at least 0.95 m.

SECURITY REQUIREMENTS

854

The safety criterion requires the creation of conditions for visiting public buildings without the risk of trauma.

The ramp that serves as an escape route from the second and higher floors must be directly connected to the exit from the building to the outside. If it is not possible to ensure the timely evacuation of all LMG in the required time, then for their rescue on the escape routes, security zones should be provided in which they can be located until the arrival of rescue teams or from which they can evacuate for a longer time. The safety zone should be an isolated room to protect people with limited mobility from the hazards of extreme events during the time until the rescue work is completed. It is recommended to provide safety zones in the halls of elevators for the transportation of fire departments, as well as in the halls of elevators used by LMG.

855

The area of the security zone must be designed for all disabled persons remaining on the floor, based on the specific area per person, provided that it can be maneuvered, m2 / person:

•disabled person in a wheelchair 2.40;

•disabled person in a wheelchair with an accompanying person 2.65;

•disabled person moving independently 0.75;

•disabled person traveling with an accompanying person 1.00.

856

Fences with handrails should be installed along both sides of stairs and ramps, as well as at all height differences of more than 0.45 m. Handrails of ramps, as a rule, are recommended to be placed at a height of 0.7 and 0.9 m, and at stairs — at a height of 0.9 m. The handrail of the inside of staircase must be continuous throughout its entire height. The final parts of the handrail should be longer than the march or the inclined part of the ramp by 0.3 m. All steps within the walkway and stairwell, as well as external stairs, must be of the same geometry and size in the width of the tread and the height of the ascent. Along the longitudinal edges of marches, ramps, along the edge of the height difference of the horizontal surface of more than 0.45 m, bumpers with a height of at least 0.05 m should be provided to prevent the foot, cane, crutch or stroller from slipping. The estimated number of people — employees and visitors, including LMG, in rooms facing a deadend corridor, should not exceed 30 people.

857

INFORMATION CONTENT REQUIREMENTS

The criterion of information requires the possibility of obtaining and understanding by the consumer of diverse information. The information should be available to all categories of users with limited mobility. It should be continuous, ensuring timely orientation of the visitor, as well as good identification of the objects and places of the visit. The information systems of a public building should be unified within a building or a complex of buildings in a residential area. Entrance points, communications, premises and service areas accessible to visitors with limited mobility, as well as places intended for parking disabled vehicles, must be marked with signs of the established international standard. Visual, audible and tactile information systems should be provided in these locations for the type and location of services provided and for possible hazards.
