(f) no exhaust from the ventilating system shall be sited in any place where it causes, or is likely to cause, annoyance or inconvenience to the public;
(g) every duct shall--
(i) be wholly constructed of non-combustible material having a strength and durability similar to that of galvanized sheet iron or steel;
(ii) be accessible for the purposes of cleaning throughout its entire length;
(iii) where its size is sufficient to allow any person to enter therein, be fitted with access openings to allow a person to enter the same for the purpose of cleaning, and shall be constructed to bear the weight of any person who has so entered;
(iv) be provided with a smooth and impervious internal surface;
(v) where it passes through any floor, wall or ceiling, be fitted with a damper which shall be operated by fusible links of a type approved by the Director of Fire Services, and designed to operate up to a temperature of 69°C, and be so constructed or protected as to resist the action of fire for a period not less than the period for which the floor, wall or ceiling through which it passes is designed to resist the action of fire;
(h) no duct shall serve more than one building;
(i) an air filter shall be-
(i) constructed wholly of non-combustible material, other than steel wool;
(ii) of a design approved by the Council; and

(j) every electrostatic filter or precipitator shall be of a type approved by the Director of Fire Services;
(k) every blower fan shall be fitted with a fused running hour meter connected to the load side of the fan contactor with a device for recording time in minutes and hours or tenths or lesser fractions of an hour;
(l) each fused running hour meter shall be sited in an easily accessible and conspicuous place to facilitate inspection;
(m) each set of filters in a ventilating system shall be indicated by a filter gauge, filter flag indicator or differential pressure switch;
(n) filters shall be cleaned or replaced when the filter gauge, filter flag indicator or differential pressure switch shows an increase of 50 pascals over the designed air filter pressure drop; and
