8 Procedure No.: WYN Page: 8 of 19 performed in and around equipment and pedestrians shall have reverse signal alarm distinguishable from the surrounding noise level and/or have a spotter to signal that it is safe to back up into an area. In addition, high visibility vests shall be required during construction work activities as well as when work is performed in high traffic areas where workers are present. This requirement may be determined as part of the Pre- Task Plan (PTP) for construction work activities or as part of the safety rules for specific works areas UNATTENDED TRUCKS A powered industrial truck is unattended when the operator is twenty-five (25) feet or more away from the vehicle which remains in their view; or whenever the operator leaves the vehicle and it is not in their view When a powered industrial truck is left unattended, loadengaging means shall be fully lowered, controls neutralized, power shut off, and brakes set. Wheels shall be blocked if the truck is parked on an incline When the operator of an industrial truck is dismounted and within twenty-five (25) feet of the truck still in their view, the load engaging means shall be fully lowered, controls neutralized, and the brakes set to prevent movement UNLOADING/LOADING OF TRANSPORTATION CONTAINERS Trailer Staging Trailer includes box trailers. Trailers that are staged (full or empty) shall be parked on an adequate surface to prevent the landing gear from sinking into the ground. Adequate surfaces may include concrete, asphalt, or gravel. If the trailer is not on an adequate surface or the integrity of the surface is in question, the foot print of the landing gear shall be increased to prevent sink-in. This can be done by placing cross ties, metal plating, or similar materials under the landing gear Trailer Inspection Trailers must be visually inspected prior to being loaded or unloaded. It is recommended the inspection be documented on

9 Procedure No.: WYN Page: 9 of 19 a preloading checklist. Visually inspect landing gear for damaged, missing or broken parts Trailer Inspection Forklift Access Trailers must be inspected prior to being entered with a forklift to identify safety issues. Items to be checked, may include but are not limited to the following: Check floors for holes and broken boards, check side walls for damage, check landing gears for any damaged to braces/welds, door hinges and latches should be fully functional, etc Trailer Securement For safe box trailer access by dock personnel, the trailer is to be restrained in such a manner as to prevent trailer '"creep or inadvertent pull-away. Brakes shall be set, powered mechanical means of restraining trailers is preferred over wheel chocks. Fixed jacks are necessary to support a trailer during unloading/loading when the trailer is not coupled to a tractor unit. If the dock isn t equipped with a dock loading mechanism, then (4) wheel blocks/chocks will be tightly placed around the tires to prevent movement in either direction. Every attempt possible should be made to use a dock with a mechanical restraint device. Place jack stands under trailers (e.g., make contact with the underside of the trailer) but don t crank the jack up tight as this will only complicate the process. Next remove or release the dock lock, wheel chocks and the jack stand once loading/unloading activities are complete. Throughout the Wyandotte site wheel chocks are required whenever a mechanical restraint device is in bypass mode Glad Hand Locks: For dropped loads/unloads Glad Hand Locks are required to be used to secure and prevent unwanted/inadvertent trailer movement When loading/unloading intermodal containers at least two restraint methods will be required to secure the chassis, one of which must include the mandatory use of wheel chocks Jack Placement - All jacks supplied should be labeled with a warning text as well as a graphic illustration to alert an operator to the requirement to snug the top surface of the jack up to the underside of the trailer frame.

Caution shall be exercised when handling offcentered loads, which cannot be centered. Loads that may tilt, roll off, or otherwise be unstable during transport shall be secured to prevent losing the load Completely engage the load with the load-engaging means during travel. Fork length should be at least two-thirds of the load length. Carefully tilt the load backwards if a tilt is provided DOCK BOARDS AND BRIDGE PLATES All portable and powered dock boards shall be strong enough to carry the loads imposed on them Portable dock boards shall be secured in position, when in use, either by being anchored or equipped with devices which will prevent their slipping Handholds, or other effective means, shall be provided on portable dock boards to permit safe handling A dock board or plate shall have a slip-resistant surface, such as but not limited to tread plate, designed to reduce the possibility of slipping by an employee or truck Brakes and chocks shall be utilized to prevent trailers from being moved while dock boards or bridge plates are in position. A Site approved, dock-mounted, trailer restraint device may be used instead of wheel chocks for trucks or trailers equipped with an "ICC" standard under ride bar and backed up to an anchored dock equipped with such a device USE AS A PERSONNEL LIFT Standard lift/fork trucks shall not be permitted to be used for lifting personnel. Aerial work platforms or scaffolding shall be used for elevated work. Exceptions shall be granted only with prior approval from Site EHS.

If the load being carried obstructs forward view, the operator shall travel in reverse with the load trailing The operator shall travel with the load raised only as far as necessary to clear the road surface and, where possible, titled back. The load shall only be elevated during stacking When ascending or descending on grades, the following procedures must be followed: Grades shall be ascended or descended slowly. When ascending or descending grades in excess of 5%, loaded trucks shall be driven with the load upgrade. On all grades, the load and load engaging means shall be tilted back, if applicable, and raised only as far as necessary to clear the road surface. Travel in a straight path, avoiding turns wherever possible Railroad tracks shall be crossed diagonally wherever possible; parking closer than 8.0 feet from the center of the railroad tracks is prohibited Protrusions of loads outside normal widths shall be marked Elevators shall be approached slowly and then entered squarely after elevator car is properly leveled. Once on elevator, controls shall be neutralized, power shut off and brakes set. The elevator s capacity shall not be exceeded.
