WAC 296-155-53306
Rigger qualifications. (1) The rigger
must meet the qualification requirements (subsection (3) of
this section) prior to performing hoisting activities for
assembly and disassembly work (WAC 296-155-53402 (19)(a)). A
qualified rigger is required whenever workers are within the
fall zone and hooking, unhooking, or guiding a load, or doing
the initial connection of a load to a component or structure
(WAC 296-155-53400 (43)(c)). This requirement must be met by
using either Option (1) or Option (2).
(a) Option (1) - Third-party qualified evaluator. The
rigger has documentation from a third-party qualified
evaluator showing that the rigger meets the qualification
requirements listed in subsection (3) of this section.
(b) Option (2) - Employer's qualified evaluator. The
employer has its qualified evaluator assess the individual and
determine that the individual meets the qualification
requirements listed in subsection (3) of this section and
provides documentation of that determination. An assessment
by an employer's qualified evaluator under this option is not
portable meaning other employers are not permitted to use this
qualification to meet the requirements of this section.
(c) The employer must make the documentation for
whichever option is used available at the site while the
rigger is employed by the employer. The documentation must
specify each type of rigging for which the rigger meets the
requirements of subsection (3) of this section.
(2) If subsequent actions by the rigger indicate that the
individual may not meet the qualification requirements listed
in subsection (3) of this section, the employer must not allow
the individual to continue working as a rigger until
retraining is provided and a reassessment is made in
accordance with subsection (1) of this section that confirms
that the individual meets the qualification requirements.
(3) Qualification requirements. Each rigger must:
(a) Know and understand the requirements located in ASME
B30.7-2006, Base-Mounted Drum Hoists, B30.9-2010, Slings,
B30.10-2009, Hooks, B30.16-2007, Overhead Hoists (Underhung),
B30.20-2010, Below-the-Hook Lifting Devices, B30.21-2005,
Manually Lever Operated Hoists and B30.26-2004, Rigging
Hardware, as applicable.
(b) Know and understand the type of sling and hitch used.
For example, if synthetic web slings are used, the rigger must
know and understand the removal criteria for this type of
sling and how to properly use the sling.
(c) Be competent in the application of the type of
hitches used.
(d) Have a basic understanding of slings, rigging
hardware and below-the-hook lifting devices (as applicable);
their limitations, rigging practices, associated hazards and
inspection requirements.
(e) Know and understand load weight estimation, center of
gravity, effect of angles on rigging components, load turning,
knots/tag lines, chain hoist/come-a-long usage, winch and
block usage, and basic hand signals, as applicable.
(f) Know and understand the relevant requirements of WAC 296-155-556 through 296-155-56220 and this section.
(g) Demonstrate that they meet the requirements in (a)
through (e) of this subsection through a written test and
through a practical test. All tests must be documented.
Note:
The provisions of subsection (3)(g) of this section are applicable one hundred eighty days after the effective date of
this section.
(4) Qualification period. A rigger qualification cannot
exceed a five-year period; this qualification must be renewed
every five years to ensure riggers maintain qualified status.
At a minimum, this renewal must include a documented written
exam.
