Shall answer with page at a surgery block to a row technical and a dignity. - a gigabyte. requirements: it is good to be ventilated (the pritochny air flow shall pass through the special filters detaining dust); to be available to wet cleaning and disinfection (in particular, using chemically aggressive means); to be rather spacious that promotes ensuring implementation of requirements of the accident prevention during the work with electric heaters and coppers of high pressure; to meet the requirements of fire safety. It is desirable that S. accommodated in 3 — 5 rooms, in to-rykh it is possible to place separately sterilizers (autoclaves), cases for dry-heat sterilization, boilers, cases storages of sterile materials and the equipment.

The current trend in implementation in practice of work to lay down. institutions of the centralized sterilization is based first of all on its reliability, and also profitability, the edge is reached due to mechanization and automation of productions.
