Haw. Code R. § 6-77-197 - Vault maintenance
(a) Each vault
housing pressure regulating and pressure limiting equipment, and having a
volumetric internal content of 200 cubic feet or more, must be inspected at
intervals not exceeding fifteen months, but at least once each calendar year,
to determine that it is in good physical condition and adequately
ventilated.
(b) If gas is found in
the vault, the equipment in the vault must be inspected for leaks, and any
leaks found must be repaired.
(c)
The ventilating equipment must also be inspected to determine that it is
functioning properly.
