PROVISIONS AS TO PREPARATION FOR, PROCEDURE ON, AND METHOD OF, EXAMINATION OF BOILERS, STEAM RECEIVERS AND AIR RECEIVERS, AND AS TO PRESSURE ACCUMULATION TESTS AND HYDRAULIC TESTS.
37. (1) Whenever, for the purposes of this Ordinance, a boiler is about to be examined when it is cold, the owner thereof shall cause the boiler to be prepared for the examination in the following manner-
(a) the boiler shall be empty and every part thereof thoroughly

(e) in the case of watertube boilers, the covers of all openings in headers, muddrums, steam and water drums, manholes and handholes shall be removed.
(2) Whenever, for the purposes of this Ordinance, a steam receiver is about to be examined when it is cold or an air receiver is about to be examined when it is not under pressure, the owner thereof shall cause the steam receiver or the air receiver, as the case may be, to be prepared for the examination so that, so far as the construction thereof permits, all parts, both internal and external, and all fittings are thoroughly clean and accessible for examination.

(d) finally, the boiler, save for any economizer or superheater that may be fitted therein, shall be examined when it is under the pressure that will be specified in the certificate of liness as the maximum permissible working pressure at which it may be operated, such examination being carried out on the first occasion on which steam is again raised in the boiler. (2) The following provisions apply to the examination of a boiler for the purposes of section 24-
(a) where an appointed examiner considers it necessary, the boiler shall first be examined when it is cold and has been prepared for examination in the manner prescribed in paragraphs (a), (c), (d) and (e) of subsection (1) of section 37;
(6) where an appointed examiner considers it necessary, the boiler shall next be subjected by an appointed examiner to an hydraulic test; and
(c) in every case, the boiler, save for any economizer or super- heater that may be fitted therein, shall be examined when it is under the pressure that will be specified in the certificate of fitness as the maximum permissible working pressure at which it may be operated, such examination being carried out on the first occasion on which steam is raised in the builer and after
