WAC 296-155-55210
Crane or derrick operation
requirements for personnel lifting. (1) Before lifting
personnel the following must be met:
(a) Operate crane/derrick with outriggers or stabilizers
extended, blocked, and locked in accordance with the
manufacturers' specifications;
(b) For crane/derrick that uses wire rope to hoist a
personnel platform, verify that the crane/derrick has an anti
two-block device or upper travel limit switch, installed and
operational;
(c) Position the personnel platform so that it may be
tied off to the structure to which the occupants are entering
or leaving, if the platform cannot be landed during the
entrance or exit of the occupants. If the platform has been
tied off, the operator must not move the platform until it is
verified that it is freely suspended;
(d) Not knowingly allow the platform load to exceed the
platform rating, except during proof testing;
(e) Not travel the crane/derrick with personnel in the
personnel platform except when they run on fixed rails or
runways;
(f) Perform all movements of the platform or
crane/derrick in a slow, controlled manner to minimize sudden
movement of the platform;
(g) Engage the power-controlled lowering mechanism at all
times the platform is occupied (no freefall);
(h) In the case of suspended or boom-mounted platforms,
without controls, the operator must remain at the
crane/derrick controls at all times when the platform is
occupied;
(i) Reserved;
(j) Platforms with controls. Where the platform is
equipped with controls, all of the following must be met at
all times while the platform is occupied:
(i) The occupant using the controls in the platform must
be a qualified person with respect to their use, including the
safe limitations of the crane/derrick and hazards associated
with its operation. See WAC 296-155-53300, Operator
qualifications and certification.
(ii) The crane/derrick operator must be at a set of crane
controls that include boom and swing functions of the crane,
or on-site and in view of the crane/derrick and platform.
(iii) The platform operating manual must be in the
platform or on the crane/derrick.
Note:
If lowering, retracting, and rotating primary power source becomes inoperative, the crane/derrick operator is allowed
to leave the controls.
(k) Set all brakes and locks on the crane/derrick after
positioning of the personnel platform and before personnel
perform any work;
(l) Move the platform under controlled conditions and
under the direction of a qualified signal person or platform
occupant(s);
(m) Not move platforms over, under, or in the vicinity of
power lines unless the requirements of WAC 296-155-55305 are
met;
(n) Not lift any other loads, on any other load lines,
while conducting a personnel lift. When the crane/derrick has
a boom-attached platform without controls, it must not be used
for other lifting service;
(o) Factory-produced boom-mounted personnel platforms
that incorporate a winch as original equipment: Loads are
permitted to be hoisted by such a winch while employees occupy
the personnel platform only where the load on the winch line
does not exceed five hundred pounds and does not exceed the
rated capacity of the winch and platform, and does not exceed
fifty percent of the crane's rated capacity at the radius and
configuration used;
(p) Not disable, or allow to be disabled, any
crane/derrick safety device during a personnel lift;
(q) Hoist the platform at a speed suitable for the safety
of the operation but in no case in excess of ninety
feet/minute (30 m/minute) or 1.5 feet/second (0.5 m/second).
(2) The operator must not move the platform without a
discernible or audible signal from a signal person.
