ANSI A92 series
>A92.2 for Vehicle-Mounted Rotating and Elevating Work Platforms
>A92.5 Boom-Supported Elevating Work Platforms

AERIAL LIFTS
Anchoring to an adjacent pole, structure or equipment while working from an aerial lift is NOT permitted
16
AERIAL LIFTS
Truck mounted bucket aerial lifts should NOT be moved while the boom is elevated in a working position with personnel in the bucket
Except for equipment specifically design for this type of operation
17
AERIAL LIFTS
Workers should stand firmly on the floor of the basket
Workers should NOT sit or climb on the railings of the basket
Do NOT use planks, ladders or other devices that allow the worker to gain additional reach

CATAPULTING ACTION – KEY POINTS
The purpose of the harness/lanyard is. . .> To keep workers inside the protection of the guardrails and in the
platform should you be bounced upward or catapulted.
> Why?
• Because once your body leaves the inside of the basket/platform you can still be seriously hurt even with proper personal fall arrest protection.
• Even getting bounced around inside the platform can lead to serious injuries

• It is strongly recommended that a full body harness with an adjustable lanyard (used to provide work restraint and adjusted to be as short as possible) is used when working from a boom type Mobile Elevating Work Platform (MEWP).

PRACTICAL APPLICATION
Purpose of the harness/lanyard . It is
NOT:> Used so the occupants can climb
onto the guardrails or out of the platform or gain additional height by standing on any other objects.
> So the occupants can lean out over the guardrails
> Much protection if the lift tips over.
A harness/lanyard has to be
considered the LAST line of defense.

KEY POINTS
Analogy for aerials lifts> Harness and lanyard in aerial lift: fall protection
Seat belt in car: crash protection
> Harness and lanyards should restrain the user
Fall protection options> Guardrail
> Fall arrest
> Fall restraint
> “User determination within manufacturer’s limitations and/or recommendations”

ANCHORAGE
Observations
Causes>Minimal industry uniformity
>Minimal guidance to user
> “We’ve always done it that way and no one has gotten hurt….Yet.”
Prevention

ANCHORAGE
Observations
Causes
Prevention>Anchorage as low as possible
>Lanyard shortened
>Snap hook that meets:
• ANSI Z359.1-2007
• ANSI Z359.12-2009
47
KEY POINTS
ANSI Z92.5-2006> Fall arrest systems, beyond the anchorage, are not part of the
aerial work platform and are to be specified and supplied by the user of the aerial work platform.
You might ask:> What about compatibility?
> What about falling outside the lift while connected to lift?
> What about clearances?

TAKE-AWAYS
1. Causes and results of catapulting events
2. Lift usage to minimize catapulting events
3. Correct use of anchorages in lifts
4. Correct use of harness and lanyards in lifts
5. Aerial lift industry is still developing requirements
57
ACTION ITEMS
Determine how lifts are being used
Keep workers in lifts> Low, compatible anchorages
> Shortened lanyards
Review this material with them
Develop procedure when exiting is safest method
