Current through Register Vol. 24-14, July 15, 2024
(1) Before lifting
				personnel you must meet the following :
(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, cautious 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, you must meet all of the following 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, and
				must be 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, you must not use it 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 500 pounds and does not exceed the rated capacity of the winch and
				platform, and does not exceed 50% 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 90 feet/minute (30 m/minute) or 1.5 feet/second (0.5
				m/second).
