AN ACT Relating to making technical changes to boiler and unfired pressure vessel statutes; amending RCW 70.79.060, 70.79.070, 70.79.080, 70.79.090, and 70.79.240; and repealing RCW 70.79.210.
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF WASHINGTON:
Sec. 1 RCW 70.79.060 and 1984 c 93 s 1 are each amended to read
as follows:
(1) Except as provided in subsection (2) of this section, no power
boiler, low pressure boiler, or unfired pressure vessel which does not
conform to the rules and regulations formulated by the board governing
new construction and installation shall be installed and operated in
this state after twelve months from the date upon which the first rules
and regulations under this chapter pertaining to new construction and
installation shall have become effective, unless the boiler or unfired
pressure vessel is of special design or construction, and is not
covered by the rules and regulations, nor is in any way inconsistent
with such rules and regulations, in which case ((a special installation
and operating permit)) an inspection certificate may at its discretion
be granted by the board.
(2) ((A special permit)) An inspection certificate may also be
granted for boilers and pressure vessels manufactured before 1951 which
do not comply with the code requirements of the American Society of
Mechanical Engineers adopted under this chapter, if the boiler or
pressure vessel is operated exclusively for the purposes of public
exhibition, and the board finds, upon inspection, that operation of the
boiler or pressure vessel for such purposes is not unsafe.
Sec. 2 RCW 70.79.070 and 1995 c 41 s 1 are each amended to read
as follows:
(1) All boilers and unfired pressure vessels which were in use, or
installed ready for use in this state prior to the date upon which the
first rules and regulations under this chapter pertaining to existing
installations became effective, or during the twelve months period
immediately thereafter, shall be made to conform to the rules and
regulations of the board governing existing installations, and the
formulae prescribed therein shall be used in determining the maximum
allowable working pressure for such boilers and unfired pressure
vessels.
(2) This chapter shall not be construed as in any way preventing
the use or sale of boilers or unfired vessels as referred to in
subsection (1) of this section, provided they have been made to conform
to the rules and regulations of the board governing existing
installations, and provided, further, they have not been found upon
inspection to be in an unsafe condition.
(3) ((A special permit)) An inspection certificate may also be
granted for miniature hobby boilers that do not comply with the code
requirements of the American society of mechanical engineers adopted
under this chapter and do not exceed any of the following limits:
(a) Sixteen inches inside diameter of the shell;
(b) Twenty square feet of total heating surface;
(c) Five cubic feet of gross volume of vessel; and
(d) One hundred fifty p.s.i.g. maximum allowable working pressure,
and if the boiler is to be operated exclusively not for commercial or
industrial use and the department of labor and industries finds, upon
inspection, that operation of the boiler for such purposes is not
unsafe.

of energy that operate at ((a)) ambient temperature ((of one hundred
thirty degrees Fahrenheit or less));
(10) Electric boilers:
(a) Having a tank volume of not more than one and one-half cubic
feet;
(b) Having a maximum allowable working pressure of one hundred
pounds per square inch or less, with a pressure relief system to
prevent excess pressure; and
(c) If constructed after June 10, 1994, constructed to American
society of mechanical engineers code, or approved or otherwise
certified by a nationally recognized or recognized foreign testing
laboratory or construction code, including but not limited to
Underwriters Laboratories, Edison Testing Laboratory, or Instituto
Superiore Per La Prevenzione E La Sicurezza Del Lavoro;
(11) Electrical switchgear and control apparatus that have no
