(a) Antislip protection. The stand of the log setters shall be provided with a nonslip surface of cleats or corrugated or rough abrasive material.

(b) Control lock. Means shall be provided for securely locking the carriage control lever of the sawyer when not in use, except in the ease of portable sawmills which have springs to bring the lever to neutral position.

(c) Emergency stop valve. If a twin or other steam engine is used exclusively for driving the carriage, a stop valve shall be placed in the main steam pipe as close to the engine as conditions permit. This valve shall be of a quick-closing type and so weighted, or otherwise actuated, that it closes automatically when released by the sawyer. Means of releasing the valve shall be provided within easy reach and control of the sawyer.

(d) Steam-operated niggers. Where a log deck is equipped with a steam-operated nigger which turns the log upward and toward the knees, the latter shall be equipped with goosenecks or extension heads.

(e) Sheave guards. If the carriage is rope driven, the sheaves shall be guarded with a box of heavy timber beveled down to the floor, except in the case of portable mills. Sheaves of cables operating rope-fed set works shall also be guarded in a similar manner.

(f) Buffer. There shall be provided in each end of the carriage run at least one substantial buffer stop capable of bringing the carriage to a full stop from its maximum speed without dangerous retardation. This requirement shall not apply to portable mills, if a clearance equal to the length of the carriage is maintained between the end of the carriage run and the nearest fixed object in line with the carriage run.

(g) Carriage run. A standard railing shall be provided opposite any door which opens into a passageway at the rear or side of a saw carriage. The railing shall be at least 18 inches from the rear of the carriage. A warning sign shall be posted on the inside of the door.

(h) Wheel guards. Substantial guards of metal or hardwood shall be provided in front of each wheel; the guards shall extend to within 1/4 inch of the rails.
