WAC 296-54-57345
Logging machines -- Moving. (1)
Operators must ensure that all employees are in the clear
before initiating or continuing the movement of any mobile
equipment. The machine must be operated far enough from
employees and other machines so that operation does not create
a hazard for an employee.
(2) At any time when moving logging machines, the driver
must have a clear and unobstructed view of the direction of
travel. When this is not possible, a signal person with a
clear and unobstructed view of the direction of travel must be
designated and used to direct the movement of the machine, or
the machine must have an audible horn that is sounded.
EXCEPTION:
This does not apply to tractors, skidders or tree harvesters during normal yarding operations.
(3) Where a signalperson is used, the equipment operator
must move the equipment only on signal from the designated
signalperson and only when the signal is distinct and clearly
understood.
(4) When moving power units, persons other than the
operator and the person in charge must not be permitted to
ride on the unit.
(5) All obstructions that may reach the operator while
moving a machine must be removed.
(6) When moving to areas within the immediate landing
area, all employees must stay in the clear of the logging
machine(s) or must inform the operator of the intent to
approach or be near the machine(s).
(7) Mobile yarders and wheel or crawler loaders must not
travel on road grades greater than 15 percent unless they are
securely snubbed or towed, or have a braking system designed
for such travel by the manufacturer.
(8) Crawler-type, track-mounted logging machines with
manual transmissions must be equipped with a ratchet or other
device that will prevent unintended disengagement or reversing
of the machine and the operator must be informed of the proper
technique.
