32. (1) All main steam pipes shall be given a general examination in place, once each year.

(2) Steam pipes connecting two or more boilers together or connecting boilers to the propelling machinery, and auxiliary steam pipes exceeding 75 mm in internal diameter subjected to a working pressure of more than 1 035 kPa shall be removed for inspection and tested by hydraulic pressure to twice the working pressure,

• (a) if the pipes are made of iron, steel or solid drawn copper, every six years, or a selected number as requested by the inspector, every four years,

• (b) if the pipes are made of copper and have a brazed longitudinal joint, every four years,

and to facilitate the inspection

• (c) sufficient lagging, as required by the inspector, shall be removed from the pipes referred to in paragraph (a); and

• (d) all the lagging shall be removed from the pipes referred to in paragraph (b).

(3) Copper steam pipes required to be inspected under this section shall be annealed from time to time when considered necessary by the inspector.

(4) Steam pipes being tested pursuant to subsection (2) shall be subjected to the hydraulic pressure required by that subsection for such time as the inspector considers necessary and any pipe that is leaking shall be repaired and re-tested.

(5) An inspector may at any time require any steam pipe to be removed for examination or testing, where, in his opinion, the bursting of such steam pipe might cause injury or loss of life.

33. (1) The propulsion machinery of every fishing vessel propelled by steam shall have all pistons, cylinders, slide valves, main bearings, top and bottom end bearings and crankshaft opened up for inspection at intervals not exceeding four years.

(2) The auxiliary machinery of every fishing vessel propelled by steam shall have such of the following parts, namely, thrusts, main shafts, feed pumps, oil fuel pumps and other essential pumps, condensers, evaporators, feed heaters and their mountings, fuel tanks, bilge pumping arrangements, pipes and valves opened up for inspection, or tested, once every four years as the inspector deems necessary.

(3) The propulsion and auxiliary machinery of every fishing vessel of more than 150 tons, gross tonnage, propelled by steam shall be inspected annually as follows:

• (a) parts that are opened up for adjustment or overhaul and are available during the attendance of the inspector, or are reported to be defective, shall be inspected; and

• (b) a running trial shall be held on the main engines, steering gear, pumps essential to the safe operation of the ship, and any other part that may be requested by the inspector, and where any part is not to the satisfaction of the inspector, he may require that part to be opened up for inspection and overhaul.

34. (1) Air receivers shall be tested by hydraulic pressure, as specified in Schedule III, when new, at the end of eight years from the date of the first inspection and thereafter every four years from the date of the last inspection.

(2) Notwithstanding subsection (1), an inspector may waive the requirement of the hydraulic test on any air receiver, other than a new air receiver or an existing air receiver being inspected for the first time, if the air receiver has a manhole or other opening that allows for a thorough examination of the interior to be made and the inspector is satisfied by such examination that the receiver is in a safe condition.
