Section 204-91A-170. Minimum tow truck equipment standards.

(1) All tow/recovery trucks used by a registered tow truck operator for public or private impounds or in response to patrol requests must meet the minimum standards listed in this section. Classes "A," "B," "B-2," "C," "D" only if factory equipped with a boom or retractable boom, "E" only if factory equipped with a side recovery system, and "S-1" are considered recovery trucks for patrol requests and must be used by the registered tow truck operator in response to these requests unless the operator requests and patrol accepts nonrecovery trucks or other equipment. The patrol will provide information concerning the general description of the type and condition of the vehicle and its type of load if applicable at the time of request for an initial tow if reasonably available.

(2) Minimum standards:

(a) All equipment used in conjunction with the tow truck winching system must be used in such a way as not to exceed the equipment working load limit. All equipment must comply with the Washington safety and health administration (WSHA) regulation if applicable.

Industry standards set the working load limit of wire rope or equivalent material at one-fifth of the manufacturer's rated nominal or breaking strength.

(b) Each wire rope or equivalent material must be capable of being fully extended from and fully wound onto its drum. Each wire rope or equivalent material must meet the industry standards for specified type of use with equipment.

OSHA (1410.179 (h)(2iiia)) requires no less than two wraps of rope remain on drum when rope is "fully extended." This is to ensure the full load never bears on the rope to drum connection.

(c) The wire rope on each recovery class truck must be equivalent to a 6 x 19 or 6 x 37 "extra improved plowed steel" (XIP) independent wire rope center (IWRC), and must meet all industry standards for working load limit.

(i) The operator must retain a receipt of purchase from the manufacturer indicating the type and WLL of wire rope, and document the type and date the wire rope was installed on each vehicle.

(ii) Class "A," "D," and "E" trucks may utilize either IWRC or fiber core wire rope.

(d) All wire rope must be in good working order. The following industry standards for out-of-service criteria will apply:

(i) No more than six randomly distributed broken wires in one rope lay, or more than three broken wires in one strand in one rope lay.

(ii) Excessive abrasion causing the loss of more than one-third the original diameter of an outside individual wire.

(iii) Evidence of rope deterioration from corrosion.

(iv) Kinking, crushing, or other damage that results in detrimental distortion of the rope structure.

(v) Any evidence of heat damage.

(vi) Any marked reduction in diameter either along the entire main length or in one section.

(vii) Unlaying or opening up of a tucked splice.

(viii) Core protrusion along the entire length.

(ix) End attachments that are cracked, deformed, worn, or loosened.

(x) Any indication of strand or wire slippage in end attachments.

(xi) More than one broken wire in the vicinity of fittings.

(e) Wire rope end connections shall be swaged or, if clamped, must have a minimum of three forged clamps spaced a minimum of six rope diameters apart and attached with the base or saddle of the clamp against the longer or "live" end of the cable. The "U" bolt will be placed over the short or "dead" end of the rope and will be of the proper size for the cable being clamped.

(i) Recovery or tow hooks must be installed, maintained, and used in the manner in which the manufacturer prescribes.

(ii) Recovery or tow hooks must be replaced if the throat opening has increased beyond the manufacturer recommendations, the load bearing point has been worn by ten percent, or the hook is twisted by more than ten degrees.

(iii) Wire rope clamps must be installed and torqued per manufacturer specifications.

(f) All wire rope related equipment, sheaves, etc., must conform to the diameter of the wire rope being used or to the original tow truck equipment manufacturer specifications.

(g) All winching equipment, booms, snatch blocks, etc., must have permanently affixed durable factory identification, stating the working load limit. If this identification has been removed or is no longer readable, it is criteria for placing the item out-of-service. Equipment may be reinspected by a recognized recertification company. If the equipment is acceptable, it may be reidentified with a working load limit and a recertification company identifier. It will be deemed acceptable if the operator maintains a copy of the certification of winching equipment provided the serial number on the equipment corresponds with the certification provided by the manufacturer.

(h) Snatch block hooks that were manufactured with a retractable safety retention clip must have a functional clip installed.

(i) All block and tackle equipment used in the winching system which shows signs of permanent deformation, significant wear or damage is criteria for placing the item out-of-service.

(j) All "J" hook chain assemblies must be grade "7" chain or better.

(k) Safety chains must only be used for the securing of vehicles to the truck. Must be minimum grade "7" chain or meet the original manufacturer's recommendations. Safety chain hooks that were manufactured with retractable safety retention clips must have a functional clip installed.

(l) Comply with legal lighting, equipment, and license requirements.

(m) Portable tail, stop, and turn signal lights for vehicles being towed. When in use, the lights must be mounted on the same level and as widely spaced laterally as practicable.

(n) Have department of licensing registration and truck numbers painted or permanently affixed to both sides of the truck. Have firm's name, city of address, and phone number permanently affixed to both sides of the vehicle. Letters must be a minimum of three inches high with one-half inch strokes.

(o) Have a revolving, strobe, or intermittent red light with three hundred sixty degrees visibility. Trucks may also be equipped with flashing amber and/or white lights which may be used in conjunction with the red lamps.

(p) Have a broom, minimum twelve inches wide, with a handle at least four feet long.

(q) Have a scoop type shovel, minimum seven inches wide, overall length minimum three feet long and a minimum of a three-gallon hard or solid sided receptacle (trash bags of any type will not meet this requirement) able to contain debris typically found at collision scenes without breaking.
