Wash. Admin. Code § 296-155-950 - Rollover protective structures (ROPS) for material handling equipment
(1) Coverage.
(a) This section applies to the following
types of material handling equipment: To all rubber-tired, self-propelled
scrapers, rubber-tired front-end loaders, rubber-tired dozers, wheel-type
agricultural and industrial tractors, crawler tractors, crawler-type loaders,
and motor graders, with or without attachments, that are used in construction
work. This requirement does not apply to sideboom pipelaying
tractors.
(b) The promulgation of
specific standards for rollover protective structures for compactors and
rubber-tired skid-steer equipment is reserved pending consideration of
standards currently being developed.
(2) Equipment manufactured on or after
September 1, 1972, Material handling machinery described in subsection (1) of
this section and manufactured on or after September 1, 1972, must be equipped
with rollover protective structures which meet the minimum performance
standards prescribed in WAC
296-155-955 and
296-155-960, as
applicable.
(3) Equipment
manufactured before September 1, 1972.
(a)
All material handling equipment described in subsection (1) of this section and
manufactured or placed in service (owned or operated by the employer) prior to
September 1, 1972, must be fitted with rollover protective structures.
Machines manufactured before July 1, 1969; Reserved pending further study, development, and review.
(b) Rollover protective structures and
supporting attachment must meet the minimum performance criteria detailed in
WAC 296-155-955 and
296-155-960, as applicable or
must be designed, fabricated, and installed in a manner which will support,
based on the ultimate strength of the metal, at least two times the weight of
the prime mover applied at the point of impact.
(i) The design objective must be to minimize
the likelihood of a complete overturn and thereby minimize the possibility of
the operator being crushed as a result of a rollover or upset.
(ii) The design must provide a vertical
clearance of at least 52 inches from the work deck to the ROPS at the point of
ingress or egress.
(4) Remounting. ROPS removed for any reason,
must be remounted with equal quality, or better, bolts or welding as required
for the original mounting.
(5)
Labeling. Each ROPS must have the following information permanently affixed to
the structure:
(a) Manufacturer or
fabricator's name and address;
(b)
ROPS model number, if any;
(c)
Machine make, model, or series number that the structure is designed to
fit.
(6) Machines
meeting certain existing governmental requirements. Any machine in use,
equipped with rollover protective structures, must be deemed in compliance with
this section if it meets the rollover protective structures requirements of the
U.S. Army Corps of Engineers, or the Bureau of Reclamation of the U.S.
Department of the Interior in effect on April 5, 1972. The requirements in
effect are:
(a) U.S. Army Corps of Engineers:
General Safety Requirements, EM-385-1-1 (March 1967).
(b) Bureau of Reclamation, U.S. Department of
the Interior: Safety and Health Regulations for Construction, Part II
(September 1971).
(7)
ROPS meeting the criteria set forth in SAE J1040 a and SAE J1040 b must be
regarded as substantially meeting the requirements of this section, even if
they do not meet all the criteria set forth in earlier criteria documents on
which the present standard is based.
