(1) Every hose-reel shall –

a) be to the approval of the local authority and fitted with hose complying with the requirements of C.A.S 183, Fire hose reels; and

b) be fitted with a nozzle having an internal diameter of 4,8 millimetres, which nozzle shall have a shut-off valve:

Provided that where, in the opinion of the local authority, the delivery of water through a hose of an internal diameter of not less than 19 millimetres would be inadequate to deal effectively with an outbreak of fire in the immediate vicinity of a hose-reel, the local authority may require the hose and the nozzle out to have internal diameters of not less than 25 millimetres and 6,4 millimetres, respectively.

(2) Hose-reels shall be provided at the rate of not less than one reel for every 420 square metres, or remaining portion thereof, of the floor area of the storey concerned, but every such reel shall be so located that all parts of such floor area can be reached by a jet of water from the hose with which it is fitted.

(3) The water-supply to all hose-reels may be fed from the domestic water-supply to the occupancy-unit served by them, or may be fled from a tank having a capacity of not less than 450 litres, or may be connected to a hydrant supply-pipe.

(4) At the hose-reel which is farthest away from the street-main, there shall be a minimum pressure of 70 kilopascals at all time when the nozzle shut-off vale is fully open.

(5) Where the water-supply to any of the house-reels is not connected to a hydrant supply-pipe, and the pressure in such water-supply pipe is less than 140 kilopascals static pressure, a single-inlet fire-pump boosting-connexion, fitted with a reflux-valve and a pressure-gauge not less than 100 millimetres in diameter, reading up to 1 400 kilopascals, shall be provided in approved position.
