Circular saws.

(1) Single circular head saws. Circular head saws must not be operated at speeds in excess of those specified by the manufacturer. Maximum speed must be etched on the saw.
(2) On all circular saw mills, the horizontal distance from the side of the saw to the nearest post of the husk or frame must be at least one inch greater than the clear vertical distance between the collars of the top and bottom saws.
(3) Circular head saws must be equipped with safety guides that can be readily adjusted without use of wrench or other hand tools. Brackets or edging supports must be installed between the saw and the side of the husk.
(4) The upper saw of a double circular mill must be provided with a hood or guard. A screen or other suitable device must be placed so as to protect the sawyer from flying particles.
(5) All circular sawmills, where live rolls are not used behind the head saw, must be equipped with an effective spreader or splitter. In any mill where the head saw is used for edging lumber, the splitter must be solid and stationary and must extend above the head blocks.
(6) Drag saws or circular cut-off saws must be arranged so they will not project into any passageway. When existing installations do not leave clear passage, saws must be fenced off in order to make it impossible for anyone to walk into them. Means to securely hold material being sawed must be provided wherever such material creates a hazard.
(7) All employees must be in the clear before starting operation of drag or swing cut-off saws.
(8) Twin circular head saws. Twin circular head saw rigs such as scragg saws, must meet the specifications for single circular head saws in subsection (1) of this section, where applicable.
