The maximum insolation regimen is recommended for pediatric, tuberculosis, trauma departments, wards for recovering patients, verandas and day rooms.
A moderate regimen should be provided for in infectious , surgical and somatic departments.
For operating rooms, intensive care units and intensive care , burns, oncological, neurological, as well as
Hon catering units are optimal m is the minimum insolation mode.
The insolation mode of the hospital premises should be taken into account when distributing patients in the wards, as it characterizes not only the conditions of natural light, but also affects the microclimate and the thermal state of patients. In addition, it is important as a factor in the prevention of nosocomial infections, since the flux of direct sunlight includes the bactericidal UV radiation of the Sun , the highest intensity of which is observed in the middle latitudes from 10 to 14 hours.
If the sky is not visible through the window, then direct sunlight does not penetrate into this room, which worsens its sanitary characteristic.
In order to ensure the healing effect of UV radiation, continuous solar exposure of any inhabited premises with a duration of at least 3 hours a day at all geographical latitudes of the country from March 22 to September 22 should be provided. Deviation from the indicated norms of insolation duration in the wards for tuberculosis and infectious patients is especially unacceptable.
All the main premises of hospitals, maternity hospitals, schools, preschool institutions should have natural light.
Orientation of windows of the main premises in A PU should correspond vetstvovat s SanPin 2.1.3.1375-03 .
Note. * – no more than 10% of the total number of beds in the department is allowed. Tomsk is located north of 55o s. w.
The orientation of operating, resuscitation, labor, and sectional orientations indicated in Table 3 excludes overheating of these rooms and the blinding effect of sunlight, as well as the occurrence of gloss from medical instruments.
In chambers oriented to the west in areas of 55o s. w. and to the south, for children from 3 years of age and older and for adults, protection of premises from overheating by the sun’s rays (blinds, visors, other devices) should be provided.
For most chambers of somatic departments, classes, group rooms in a preschool educational institution, the orientation Yu, SE is favorable; permissible orientation – SW, B; unfavorable – З, СЗ, С, СВ.
Lighting with a second light, that is, through the glazing of the upper part of the inner wall separating two adjacent rooms (class – a corridor, kitchen – bathroom, etc.), or only artificial is allowed in the rooms of pantries, bathrooms at the wards, personal hygiene rooms, enema and some others.
The corridors of the ward sections (compartments) must have natural lighting through windows in the end walls of buildings and in light pockets (halls). The distance between the light pockets should not exceed 24 meters; from the end to the pocket – no more than 36 meters. In the corridors of the medical diagnostic and auxiliary units, end or side lighting is provided.
Note. In order to prevent a decrease in natural light and insolation in the premises of health facilities, trees on its territory are planted at a distance of no closer than 15 meters, and shrubs – 5 meters from buildings.
Rationing and assessment of lighting of designed and functioning rooms is carried out by lighting (design, instrumental) and geometric methods.
