(2) At least two people must be present for stowing, sorting or boom work of any kind except when one person is feeding the slip (hot lane) from a designated area. (3) All water dumps must have brow logs except when logs are lifted from the truck or rail car. (4) If mobile log handling machines are used to dump loads, adequate stops must be provided to prevent the machines from running off the edge of the dump. (5) When a brow log is used with a parbuckle system, all personnel are prohibited from going between the brow log and the load of logs at any time. (6) Unloading lines must be arranged so that it is not necessary for a person to attach them on the water or dump side of the load. (7) The unloading machine operator must: (a) Have an unobstructed view of the dump and the logs being unloaded; or (b) Receive a signal before dumping the logs. (8) All personnel must be in the clear and a signal given before logs are dumped. (9) When dry land log dumps use unloading methods similar to those of water dumps, OAR 437-007-1160(5) through (8) will apply. (10) All personnel working on logs or around boom sticks in water must wear sharp-caulked shoes or slip-on sharp-caulked shoes. (11) Metal or conductive pike poles must not be used around exposed electrical conductors. (12) Defective poles, blunt or dull pikes must not be used. (13) Sufficient walkways and floats must be installed and securely anchored to provide safe passage for personnel. (14) Decks, floats or other walkways must be kept above the waterline at all times, and they must be capable of supporting four times the imposed load. (15) Pond rafts must be removed from service when they are no longer capable of remaining above water while supporting a 500-pound load on any edge. (16) All regular boom sticks and foot logs must be: (a) Reasonably straight, free of protruding knots and have the bark removed, and (b) Capable of supporting any necessary weight of personnel and equipment above the waterline at either end. (17) Gaps between ends of boom sticks must not exceed 24 inches. (18) All wire must be removed from booms and chains before they are reused or hung in rafting stalls. (19) Permanent cable swifters must be arranged so it will not be necessary to roll boom sticks in order to attach or detach them. (20) When cable swifters or dogging lines become hazardous from an excessive amount of jaggers, they must be discarded. (21) Stiff booms must be constructed of not less than two float logs or equivalent timbers and must have a minimum width of 36 inches. (22) Float logs or equivalent timbers must be securely joined together by not less than 4-inch by 6-inch cross ties. (23) Stiff booms must be planked over with not less than 2-inch planking, securely fastened and kept in good repair, at all sorting gaps or locations where mechanical devices are operated. (24) Walkways along sorting gaps must be at least 4 feet wide. Other planked walkways must be at least 22 inches wide. (25) Life rings attached to 90 feet of 1/4-inch line with a minimum breaking strength of 500 pounds, must be provided at convenient points adjacent to water that is 5 feet or more in depth. (26) Life rings must have a minimum of 30 inches outside diameter and 17 inches inside diameter. (27) Life rings must be maintained so as to retain a 32-pound positive buoyancy.
