(1) This chapter has been compiled with the purpose of consolidating
safety and health construction safety standards into one chapter of the
Washington Administrative Code, by the promulgation of the standards contained
herein. It is also the intent that the safety standards of the Washington
state department of labor and industries, will be at least as effective
as those adopted by the U.S. Department of Labor and administered by the
Occupational Safety and Health Administration as published in the Code
of Federal Regulations. The department of labor and industries is incorporating
many of the preexisting construction safety standards and adding new standards
under this chapter.
(2) Attention is called to the fact that certain Washington state standards
contain standards and/or regulations applicable to all industries. These
include, but are not limited to: The code for boilers and pressure vessels;
the code for pressure piping; the general industrial safety and health
standards; the general occupational health standards; regulations of the
department of social and health services..
WAC 296-155-003 Subsections,
subdivisions, items, subitems, and segments.
(1) That portion of section numeration appearing after the chapter
designation appears in either a three digit or a five digit format
(e.g. WAC
296-24-330 and 296-24-33002). The final two digits of the
section number are implied decimal extensions of the first three
digits and represent a further division of the three digit enumeration.
(2) Sections of this chapter may be divided into subsections (1), (2),
(3), etc., which may in turn be divided into subdivisions (a), (b), (c),
etc., which may be further divided into items (i), (ii), (iii), etc.,
which may be further divided into subitems (A), (B), (C), etc., which
may be further divided into segments (aa) [(I)], (bb) [(II)], (cc) [(III)],
etc., all according to the following hierarchy, e.g.
Note: “Part” as used in this standard means a major
division of this chapter relating to a specific topic or topics and containing
various related sections.
(1) The standards included in this chapter apply throughout the state
of Washington, to any and all work places subject to the Washington
Industrial Safety and Health Act (chapter
49.17 RCW), where construction, alteration, demolition, related
inspection, and/or maintenance and repair work, including painting
and decorating, is performed. These standards are minimum safety
requirements with which all industries must comply when engaged
in the above listed types of work.
(2) If a provision of this chapter conflicts with a provision
of the general safety and health standard (chapter
296-24 WAC), the general occupational health standard (chapter
296-62 WAC), or the safety and health core rules (chapter
296-800 WAC), the provision of this chapter shall prevail.
When a provision of this chapter conflicts with a provision of
another vertical safety standard applying to the place of work,
the provisions of the vertical standard of specific application
shall prevail.
WAC 296-155-006 Equipment
approval by nonstate agency or organization.
Whenever a provision of this chapter states that only that equipment
or those processes approved by an agency or organization other than the
department of labor and industries, such as the Underwriters Laboratories
or the Mine Safety and Health Administration (MSHA) and the National Institute
for Occupational Safety and Health (NIOSH), shall be utilized, that provision
shall be construed to mean that approval of such equipment or process
by the designated agency or group shall be prima facie evidence of compliance
with the provisions of this chapter.
WAC 296-155-007 Incorporation
of standards of national organization.
Whenever a provision of this chapter incorporates by reference a national
code or portion thereof which has been adopted by and is currently administered
by another state agency, compliance with those provisions adopted and
administered by such other state agency, if from a more recent edition
of such national code, will be deemed to be prima facie evidence of compliance
with the provisions of this chapter.
WAC 296-155-008 Incorporation
of standards of federal agency.
(1) Whenever a provision of this chapter incorporates therein provisions
of the Code of Federal Regulations (CFR) and changes thereto, or any other
regulations adopted by an agency of the federal government, that provision
of this chapter shall be construed to mean that compliance with such regulations
shall be prima facie evidence of compliance with the provisions of this
chapter.
(2) Whenever a provision of this chapter incorporates therein provisions
of the Code of Federal Regulations, the provisions so incorporated shall
be those in effect on the date of effectiveness of this chapter, unless
the content of the incorporating section specifies otherwise.
WAC 296-155-009 Equipment
whether or not owned by, or under control of the employer.
(1) It is the employer's responsibility to ensure that any defective
equipment or tools are not used.
(2) When any tool or piece of equipment fails to meet the requirements
of any safety standard or recognized safe practice, the tool or equipment
shall not be used.
Realizing that conditions may exist in operations under which certain
state standards will not have practical application, the director of the
department of labor and industries or his/her authorized representative
may, pursuant to this section, sections eight or nine of the Washington
Industrial Safety and Health Act (chapter 80, Laws of 1973, RCW 49.17.080
and 49.17.090) and appropriate administrative rules of this state and
the department of labor and industries and upon receipt of application
and after adequate investigation by the department, permit a variation
from these requirements when other means of providing an equivalent measure
of protection are afforded. Such variation granted shall be limited to
the particular case or cases covered in the application for variance and
may be revoked for cause. The order granting a variance shall be conspicuously
posted on the premises and shall remain posted during the time it is in
effect. A copy of the variance shall be available at the work site. All
requests for variances from safety and health standards included in this
chapter, shall be made in writing to the director of the department of
labor and industries at Olympia, Washington, or his/her duly authorized
representative, Department of Labor and Industries, P.O. Box 44600, Olympia,
