IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
Sec. 1.
RCW 70.79.240 and 1951 c 32 s 22 are each amended to read as follows:
Each boiler and unfired pressure vessel used or
proposed to be used within this state, except boilers or unfired pressure
vessels exempt in RCW 70.79.080 and 70.79.090, shall be thoroughly inspected as
to their construction, installation, condition and operation, as follows:
(1) Power boilers shall be inspected annually
both internally and externally while not under pressure ((and)),
except that the board may provide for longer periods between inspections where
the contents, history, or operation of the power boiler or the material of
which it is constructed warrant special consideration. Power boilers shall
also be inspected annually externally while under pressure if possible;
(2) Low pressure heating boilers shall be
inspected both internally and externally biennially where construction will
permit;
(3) Unfired pressure vessels subject to
internal corrosion shall be inspected both internally and externally biennially
where construction will permit, except that the board may, in its discretion,
provide for longer periods between inspections;
(4) Unfired pressure vessels not subject to
internal corrosion shall be inspected externally at intervals set by the board,
but internal inspections shall not be required of unfired pressure vessels, the
contents of which are known to be noncorrosive to the material of which the
shell, head, or fittings are constructed, either from the chemical composition
of the contents or from evidence that the contents are adequately treated with
a corrosion inhibitor, provided that such vessels are constructed in accordance
with the rules and regulations of the board or in accordance with standards
substantially equivalent to the rules and regulations of the board, in effect
at the time of manufacture.
Sec. 2.
RCW 70.79.250 and 1951 c 32 s 23 are each amended to read as follows:
In the case of power boilers a grace period of not
more than two months longer than the ((twelve months)) period established
by the board under RCW 70.79.240(1) may elapse between internal inspections
of a boiler while not under pressure or between external inspections of a
boiler while under pressure; in the case of low pressure heating boilers not
more than twenty-six months shall elapse between inspections, and in the case
of unfired pressure vessels not more than two months longer than the period
between inspections prescribed by the board shall elapse between internal
inspections.
