American National Standard For Vehicle-Mounted Bridge Inspection and Maintenance Devices 1 Introduction Mobile units covered by this standard are generally designed to be supported on bridge surfaces of varying degrees of grade and super-elevation and have the capability of providing personnel quick and easy access to the underside of such structures. The rapid development of a wide variety of trailer and truck-mounted mobile unit designs necessitates the establishment of standards for their design, manufacture, remanufacture, installation, performance, inspection, training, maintenance, testing and use. Normally, they are not insulated for use near electrically energized apparatus nor are they intended to be used in hazardous locations. Any mobile unit intended for use around energized electrical apparatus shall be designed, manufactured, and used in accordance with the requirements outlined in ANSI/SIA A92.2-2009, Vehicle-Mounted Elevating and Rotating Aerial Devices. The operation of any mobile unit is subject to certain hazards that can be protected against only by the exercise of intelligence, care, and common sense and not by mechanical means. It is essential to have competent, careful personnel trained in the intended use, safe operation, maintenance and service of this type of equipment. 2 Scope, Purpose and Requirements 2.1 Scope 2.1.1 Equipment covered.

identified hazards, and explain the potential consequences of not following proper operating guidelines. Instructions and guidelines regarding proper operation shall include, but not necessarily be limited to the following issues and subjects: 9.10.1 Fall protection. Principal fall protection is provided by the guardrail system. The user shall direct and monitor the operator to ensure that all components of the guardrail system are in place. 9.10.1.1 Platform (bucket/basket) less than fifty (50) sq. ft. The user shall direct and monitor occupants of the work platform to ensure that they wear a personal fall arrest system (attached to lanyard) to protect against the potential effects of ejection or a fall restraint system to prevent free fall. Election of systems: The user may elect to use either a restraint or an arrest system. (1) Fall restraint systems - an anchorage, belt or harness

and a lanyard which prevent free fall. These systems are arranged to keep occupants in the platform in the event of dynamic forces which might cause ejection. (a) Occupants shall use a restraint system to keep the

occupant(s) within the platform. (b) Restraint systems may include either belts or

harnesses and do not include arresting or deceleration devices.

(2) Fall arrest system - an anchorage, full body harness and a lanyard used to arrest an employee in a fall from a Bridge Inspection and Maintenance Device. Such systems allow a fall over the guardrail system. The force applied to the body shall be limited to 1800 lbs. (8,000N).

(3) A fall arrest system shall allow workers to move around the platform but provide a minimum of lanyard slack.

(4) A fall arrest system for Bridge Inspection and Maintenance Devices shall include a lanyard and full body harness. A deceleration device if used will not allow a fall further than that required to arrest the fall without exceeding 1800 lbs. (8,000N) of force on the worker. (5) Access to systems.

energized and visibly grounded at the point of work, or where insulating barriers have been erected to prevent physical contact with the lines, the user shall ensure all applicable safety related work practices intended to prevent electric shock covered by the Code of Federal Regulations (CFR) 1910.333 shall be defined and explained to the operator by a qualified person. In particular, such person shall direct the operator, commensurate with the operator’s qualifications, to maintain the appropriate minimum approach distance (MAD) from energized power lines and parts covered by CFR 1910.333 (c).

(2) If cage-type boom guards, insulating links, or proximity warning devices are used on Bridge Inspection and Maintenance Devices, the operator shall operate the Bridge Inspection and Maintenance Devices per the requirements of (1) above, even if cage-type boom guards, insulating links, or proximity

37

warning devices are used for any reason including laws or regulations. In view of the complex, invisible, and lethal nature of the electrical hazards involved, and to lessen the potential of false security, the limitations of such devices, if used, shall be understood by the operating personnel. All such devices shall be tested in the manner and at the intervals prescribed by the manufacturer of the device.
