N.M. Code R. § 14.9.4.27 – Preparation of Boilers

A. After timely notification, it shall be the responsibility of the owner or user to prepare the boiler for inspection. To prepare a boiler for internal inspection, all manhole plates, handhold plates, washout plugs and water column connection plugs shall be removed and the waterside thoroughly washed. Furnace, combustion chambers and tubes must be thoroughly cleaned and grates of internally-fired boilers, brickwork or other insulation material shall be removed to determine the condition of the shell furnace, mud drum, heads or any covered pressure part. The chamber of the low water fuel cutoffs shall be opened and the float or probes removed.
B. Any leakage of steam or hot water into the boiler shall be prevented by disconnecting the pipe or valve at the most convenient point or any appropriate means approved by the special inspector.
