Wheelchair Securement and Occupant Restraint Systems
Pre-Trip Inspection
Is each securement station properly equipped with four securement straps, a lap belt, and a shoulder
belt?
Are all straps and belts in good working condition? Any defects such as cut, frayed, contaminated or
damaged webbing, improperly functioning buckles or hardware, or broken or worn parts, require replacement of the entire strap or belt assembly.
Are all fl oor anchorages, (i.e., tracks or plates), clear of dirt or debris to allow for proper system fi tting
attachment?
Is there a clean, dry container in the vehicle to allow for storage of the system when not in use?
Is the vehicle equipped with a web/belt cutter for use in the event of an emergency evacuation?
Are complete system operational instructions, in either printed or decal form, located within the vehicle
compartment to serve as a reference?
CAUTION! Never utilize the Occupant Restraint System unless you are fully trained,
if you’re not sure what to do, always call your Kinedyne Representative for Assistance!
