4. Operating theatres.​

  • (1)
    Operating theatres and anaesthetic rooms shall be dealt with by combined input and extract systems to provide at least ten complete air changes per hour.

  • (2)
    The air inlets should be at high level with extraction points at low level. Recirculation arrangements should not be provided. The incoming air should be filtered and air conditioned (the theatre temperature being capable of adjustment with mechanical requirements within the range 20°C to 24.4°C.

PART I - GENERAL RULES

  • 1.
    The permitted limit of unprotected areas in any side of a building or compartment shall be calculated by reference to the requirements of Part II , Part III or Part IV .
  • 2.
    In calculating the size of unprotected areas or the permitted limit of unprotected areas, the following provisions shall apply:
    • (a)
      where any part of an external wall is an unprotected area, only because it has combustible material attached to it as cladding, the area of that unprotected area shall be deemed to be half the area of such cladding:
    • (b)
      no account shall be taken of any of the following:
      • (i)
        an unprotected area unless it is an area specified in subparagraph (iii) hereof, which does not exceed 0.1 square metre and which is not less than 1.5 metre from any other unprotected area in the same side of the building or compartment;

  • 2.
    For the purpose of this Part—
    “plane of reference”
    means any vertical plane which touches the side or some part of the side of a building or compartment, but which (however far extended) does not pass within the structure of such building or compartment (and for this purpose, any balcony, coping or similar projection shall be deemed not to be part either of the side or of the structure); and the relevant plane of reference shall in each case be taken as the most favourable in that respect to the person erecting the building;
    “enclosing rectangle”
    means the smallest rectangle on the relevant plane of reference which would—
    • (a)
      enclose all the outer edges of any unprotected areas of the building or, if the building is divided into compartments, of the compartment (other than any part of unprotected area which is at angle of more than 80° to the plane of reference), the outer edges being for this purpose projected on the plane of reference by lines perpendicular to such plane;
    • (b)
      have two horizontal sides;
    • (c)
      have height and width falling within those listed in the Tables to this Part;
    “unprotected percentage”
    means the percentage of the area of the enclosing rectangle which is equal to the aggregate of the unprotected areas taken into account in calculating the enclosing rectangle and as projected on it.

PART III - RULES FOR CALCULATION BY REFERENCE TO AGGREGATE NOTIONAL AREA

  • 1.
    The conditions of this Part shall be satisfied if a building is so constructed that the aggregate notional area of the unprotected areas in the side of a building or compartment does not exceed---
    • (a)
      210 square metres (if the building or compartment is of Purpose Group I, II, III, IV or VII); or
    • (b)
      90 square metres (if the building or compartment is of Purpose Group V, VI or VIII);
    • such calculation being made by reference to any one of a series of vertical data, measured at intervals of not more than 3 metres from one another along the relevant boundary.
  • 2.
    For the purposes of this Part---
    “aggregate national area”
    means the aggregate of the areas of any unprotected areas in the side of a building or compartment, each such area being multiplied by the factor specified in the Table to this Part according to the distance of such unprotected areas from the vertical datum;
    “vertical datum”
    means a vertical line of unlimited height at any point on the relevant boundary;
    “the datum line”
    means the line joining a vertical datum to the nearest point of the side of the building or compartment.
  • 3.
    For the purposes of this Part, no account shall be taken of any unprotected area in the side of a building or compartment which is---
    • (a)
      screened from the vertical datum by any part of an external wall which is not an unprotected area; or
    • (b)
      outside a horizontal arc having its centre at a point through which the vertical datum passes and having a radius measuring 50 metres and extending 90° on either side of the datum line; or
    • (c)
      facing away from the vertical datum, or making an angle not exceeding 10° with a line drawn from it to the vertical datum.

NOTIONAL PERIODS OF FIRE RESISTANCE [By-law 158(3), 224]​

  • In this Table–
  • (a)
    “Class 1 aggregate” means foamed slag, pumice, blastfurnace slag, pelleted fly ash, crushed brick and burnt clay products (including expanded clay), well-burnt clinker and crushed limestone.
    “Class 2 aggregate” means flint gravel, granite and all crushed natural stones other than limestone.
  • (b)
    Any reference to plaster means --
    • (i)
      in the case of an external wall 1 m or more from the relevant boundary, plaster applied on the internal face only;
    • (ii)
      in the case of any other wall, plaster applied on both faces;
    • (iii)
      if to plaster of a given thickness on the external face of a wall, except in the case of a reference to vermiculite-gypsum or perlite-gypsum plaster, rendering on the external face of the same thickness;
    • (iv)
      if to vermiculite-gypsum plaster, vermiculite-gypsum plaster of a mix within the range of 1½ to 2:1 by volume.
  • (c)
    Load assumed to be on inner leaf only except for fire resistance period of four hours.
