WAC 296-307-48053
What requirements apply to
pressure-reducing regulators? (1) Pressure-reducing regulators
must be used only for the gas and pressures for which they are
intended. The regulator inlet connections must meet the
requirements of the Regulator Connection Standards, 1958,
Compressed Gas Association.
(2) When regulators or parts of regulators, including
gauges, need repair, the work must be performed by skilled
mechanics who have been properly instructed.
(3) Gauges on oxygen regulators must be marked "USE NO OIL."
(4) Union nuts and connections on regulators must be
inspected before use to detect faulty seats that may cause
leakage of gas when the regulators are attached to the cylinder
valves. Damaged nuts or connections must be destroyed.
