WAC 296-54-501 Scope and application.
The requirements of this chapter augment those requirements of the general safety
standards promulgated by the department of labor and industries, division of industrial
safety and health, applicable to this industry, and apply to all persons, firms,
corporations or others engaged in logging operations that come within the jurisdiction of
the department of labor and industries. The requirements herein contained do not apply to
log handling at sawmills, plywood mills, pulp mills or other manufacturing operations
governed by their own specific safety standards.
The safety requirements herein contained are not to be construed to imply that other
safe work practices, procedures or methods should not be employed where such methods,
means or practices may be required to prevent accidents. Both employers and employees have
a duty to do whatever is reasonable and practical to avoid causing accidents. These
requirements are minimum safety requirements and shall augment other safety standards
developed by the department which are of a general nature and apply to all industrial
operations such as those contained in the general safety standards, chapter WAC 296-24
WAC; occupational health standards, chapter WAC 296-62 WAC; and precautionary labeling of
containers of hazardous materials, chapter WAC 296-64, or others which may be applicable.
Regulations adopted by the department concerning certain types of equipment or conditions,
such as metal and nonmetallic mines, quarries, pits and crushing operations, chapter WAC
296-61, and possession, handling and use of explosives, chapter WAC 296-52 WAC shall be
complied with when applicable.
Some of the factors involving safe practices are use of good judgment, and the
avoidance of taking chances. Accidents can be avoided in many instances by everyone
conscientiously applying their knowledge of safety.
Copies of all society of automotive engineers reports (SAE) referred to in these
standards are on file in all district offices of the division of industrial safety and
health of the department of labor and industries, and may be reviewed by any interested
person. Individuals desiring to obtain copies of such material shall arrange to do so
directly from the publishers or from other sources. The division of industrial safety and
health will not assume the responsibility of acquiring such material for uses other than
its own needs.
Note: Safety standards for pulpwood logging are contained in a separate edition titled

for a quick escape to be in the clear from a falling tree.
WAC 296-54-529(39)
(39) When falling, a positive means, method or procedure that will prevent accidental
cutting of necessary holding wood shall be established and followed. Particular care shall

(9) Miscellaneous requirements.
WAC 296-54-543(9)(a)
(a) All lines, straps, blocks, shackles, swivels, etc., shall be inspected frequently
and shall be used only when found to be in good condition. Such items shall be of
sufficient size and strength as to safely withstand the stress which can be imposed by the
maximum pull of the power unit against such equipment or devices as rigged or used in that
particular logging operation.
WAC 296-54-543(9)(b)
(b) When used or second-hand cables are purchased, they shall not be used for any
purpose until inspection determines they will withstand the maximum imposed strain.
WAC 296-54-543(9)(c)
(c) Skyline shall be anchored by placing three full wraps around tail hold and staples
or spikes shall be used to securely hold each wrap or choked and secured with a shackle or
three wraps and at least three clamps securely tightened.
WAC 296-54-543(9)(d)
(d) When using haulback lines greater than 7/8-inch diameter on interlocking drum-type
yarders, additional precautions shall be taken to prevent the corner blocks or tail blocks
from dislodging the anchors to which the blocks are secured.
WAC 296-54-543(9)(e)
(e) Where "dutchman" is used, either for yarding or on skyline, a block of
heavy construction must be used. Regular tree shoe or jack may be used for
"dutchman" on skyline. Cable must be fastened securely.
WAC 296-54-543(9)(f)
(f) Choker drops shall be connected to the butt rigging by knobs or shackles. The use
of molles or cold shuts is prohibited in all components of the butt rigging. All butt
rigging shall be designed to prevent loss of chokers and defective swivels shall not be
used. Open hooks shall not be used to connect lines to the buttrigging.
WAC 296-54-543(9)(g)
(g) When heel tackle is fastened near machine, safety line must be placed in such
manner that in case of breakage, lines shall not strike power unit and endanger operator.
WAC 296-54-543(9)(h)
(h) Only in case of necessity shall any metallic object be driven into a log. The metal
must be removed immediately when splice or other work is completed. Stumps shall be used
whenever possible for splicing.
Put Clips On Right
WAC 296-54-543, Figure No. 2 1240
Figure No. 2
Clips should be spaced at least six rope diameters apart to get the maximum holding
power and should always be attached with the base or saddle of the clip against the longer
or "live" end of the rope. The "U" bolt goes over the dead end. This
is the only right way. Do not reverse the clips or stagger them. Otherwise the
"U" bolt will cut into the live rope when the load is applied. After the rope
has been used and is under tension, the clips should again be tightened to take up any
looseness caused by the tension reducing the rope diameter. Remember that even when
properly applied, a clip fastening has only about eighty percent of the strength of the
rope and far less than that when on wrong.

WAC 296-54-597(1)
(1) Track gangs, bridge crews, etc., when working on railroads in use shall place a
yellow caution flag by day and a yellow lantern by night a sufficient distance both
directions from the crew to protect them against approaching equipment. The operator of
said equipment shall acknowledge the signal by two short blasts of the whistle or horn and
proceed with caution. When said crews are removing or replacing a rail or are performing
any other work that would make it necessary for approaching equipment to come to a stop,
they shall place a red flag by day and a red lantern by night in the center of the track a
sufficient distance in both directions from the crew to protect them against said
equipment. The operator of approaching equipment shall acknowledge the signal by one short
blast of the whistle or horn and shall come to a dead stop and remain standing until the
signal is removed by the person who placed it, or until investigation proves that the
track is safe for passage. If a flagman is used, the above provision need not apply.

(5) Whenever workmen are repairing, working on or in railroad equipment, loading or
unloading cars or performing other duties where there is danger of the railroad equipment
being struck by other moving railroad equipment; proper means, methods or safeguards shall
be used to protect such workmen. A derail shall be used to prevent other rail equipment
from contacting such cars or equipment or endangering the workmen. After cars are spotted,
blue flags shall be placed in the center of the tracks at least fifty feet from the end
car during the day and blue lights shall be installed at such locations at night. Flags,
lanterns and derails shall be removed only by the person placing them unless they are to
remain posted for a longer period of time, in which case one person on each oncoming shift
shall be responsible to ascertain that they are in place and he shall not remove such
safeguards until he investigates to make certain all persons are in the clear. Operators
of approaching equipment shall not pass or remove a flag or lantern which is properly
posted. Cars or other equipment shall not be placed where it will obscure the signal from
an operator controlling approaching equipment. [Statutory Authority: RCW

distinct. If in doubt, the operator shall repeat the signal as understood and wait for
confirmation.
WAC 296-54-601(12)
(12) A horn or whistle which is automatically activated by the radio or electric
signaling system shall be used on each yarder used for skyline, high lead, skidder or
slackline system of yarding, except where hand signals are permissible. The horn or
whistle shall emit a sound which will be clearly audible to all persons in the affected
area. Such a horn or whistle shall also be required on combination yarding and loading
machines and tree pullers. Audible signals are not necessary on grapple or other yarding
systems where persons are not exposed to the movement of logs or rigging.
WAC 296-54-601(13)
