WAC 296-56-60075
Cargo boards and other type pallet boards. (1) "Cargo board" means the typical wing or lip-type stevedore
board hoisted to or from vessels by means of a bar bridle. "Other pallet boards" includes all other platforms used to hold
cargo for the purpose of transporting it from place to place.
(2) All pallets and cargo boards shall be of such material
and construction as to safely support and carry loads being
handled.
(3) All cargo boards shall be sheathed (decked) top and
bottom with the top sheathing being of two-inch lumber and
extending at least six inches beyond the end stringers.
(4) The outer sheathing boards or boards adjacent thereto on
cargo boards shall be fastened to the stringers by bolts and
nuts. Other sheathing shall be fastened by bolts and nuts, drive
screws (helically threaded nails), annular threaded nails, or
fastenings of equivalent strength.
(5) Pallet boards, other than cargo boards, may be hoisted
if safe means are provided for the type of board used.
(6) Loaded cargo or pallet boards which do not meet the
requirements of this section shall be reboarded or placed on
cargo boards meeting the requirements of this section before
being hoisted, only if the weight of the load can be safely
distributed on the cargo board.
(7) Cargo boards which are not loaded and secured so that
the load will not tip or fall shall not be hoisted.
(8) Bridles used to handle flush-end or box-type pallets
shall be of such a design as to prevent them from becoming
disengaged from the pallet under load.
Note:
In areas where a two lip cargo board is being used, that practice shall continue. The department of labor and industries recommends
the use of the two lip cargo board.
