Section 8 Responsibilities of Owners was reorganized and new items were added in the inspection and test requirements: A significant change found in the design of insulated units is a requirement that lower controls be readily accessible in all boom positions and be installed such that an operator is not placed in the electrical path between the aerial device and the ground.
This standard is also available in these packages:. Any suspected items shall be carefully examined or tested and a determination made by a qualified person as to whether they constitute a safety hazard. Two new requirements for operator aids are a slope indicator and an outrigger anxi device.
ANSI A | Transfer Oil S.p.A. – Thermoplastic hoses & Fittings
Since then, the standard has been reissued in four editions inandand most recently in McAlexander, who joined the A92 revision effort inwas chairman of the A This training shall be offered initially and subsequently on request. Presence of unauthorized persons.
For multi-phase lifting with conductor holders and a cross-arm, phase to phase protection shall be accomplished with a cross-arm that is rated, tested and maintained for the appropriate line voltage. Switching and Tagging July-August Incident Analysis March-April These tools are to be depended upon for primary protection, just as in all cases where the boom is used snsi secondary protection Categories B and C.
ANSI Approves Revised A92.2 Standard for Vehicle-Mounted Aerial Lifts | Construction News
All unsafe items shall be replaced or repaired before use. The override mode shall maintain its function while unattended.
The standard includes a new appendix, which discusses concepts important for work around energized conductors. A qualified line clearance tree trimmer, as an operator, shall not approach energized conductors or facilities that will place the insulating or non-insulating aerial device, the operator and other occupants, and their tools, closer to such facilities than the distances set forth in Parts 29 CFR Check functionality of emergency controls.
ANSI A Vehicle Mounted Elevating and Rotating Work Platforms
Live-line tool rods, tubes and poles shall be designed and constructed to withstand the following minimum tests: The types of devices covered include extensible boom aerial devices, aerial ladders, articulating boom aerial devices, vertical towers or a combination of any of these.
All components crossing the insulating portions of the aerial device shall have electrical insulating values consistent with the design voltage rating of the boom, and when provided, of the chassis insulating system. If the owner uses other entities as agents, e.
Visually inspect fiberglass and insulating components for visible damage and contamination. Please first verify your email before subscribing to alerts. The Minimum Approach Distances may be obtained from sources such as, but not limited to: Proper operation of interlocks. Design and construction requirements of the original edition of A Perform functional test to include, but not limited, to andi following: Safety rules and work practices may vary significantly for different users, but one universal rule that applies is when jibs are used as a live-line tool with category B and C aerial devices, platform occupant s must use protective equipment such as gloves and cover-ups.
Guest Friday, 09 November A qualified lineman, as an operator, annsi not approach energized conductors or facilities that will place the insulating or non-insulating aerial device, the operator and other platform occupants, and their tools, closer to such facilities than the distances set forth in Part 29 CFR The revision of A Deployment may be sensed when the outriggers meet resistance or by receipt of an indicative response that the outrigger deployment is beyond a predetermined position.
Safety Rules and Work Practices: The insulating system shall maintain the electrical insulating values in all working boom positions as defined by the manufacturer. Chassis Insulating System — An insulating system of dielectric components installed between the chassis and the upper insulating boom.
These aerial devices shall be equipped with a lower test electrode system. Insulating devices when used for bare-hand work Category A require shunting of an existing chassis insulating system. Subsurface chambers such as underground x92.2 components or septic systems.

This standard applies to the design, manufacture, testing, inspection, installation, maintenance, use, training, and operation of vehicle-mounted aerial devices. Whatever upper control arrangement is provided shall be identified. Already Subscribed to this document. The subcommittee worked on the standard from until its eventual approval in July If the winch line is used to lift energized apparatus, the energized apparatus shall be insulated from the jib tip with electrical protection devices that are rated, tested and maintained for the appropriate line voltage.
Excessive slopes, drop-offs, curbs and floor obstructions. Upper controls that incorporate components for their electrical resistance should be tested to assure resistance by testing them at 9a2.2 40 kV AC or 56 kV DC for 3 minutes with a maximum current level of microamperes for the AC test and 56 microamperes for the DC test.

A92.2: The 2009 Standard
Standards Subsctiption may be the perfect solution. Training of qualified person s is the responsibility of the employer or his designated contractor s and can be classroom, hands-on or a combination, as deemed appropriate by the employer for the degree of risk involved. An interlock override switch may be provided; however, the override mode of operation shall disable automatically. The Draft of the Standard was balloted twice by the committee and by ANSI rules was opened for public comment prior to final approval.
Categories B and C machines may incorporate control systems with high electrical resistance components.
