Safety- Aerial Lift Flashcards
The two main risk associated with operating an aerial lift are:
Electrocution and Falling
Caused by operating too close to power lines or using unsafe work practices.
Electrocution
Three common causes of aerial lift accidents:
Stability problems, Operating Errors, Violating OSHA regulations
Pay attention to _____ and _____ to ensure stability.
slope and road material
Movable, mechanical structure used to support a platform, material handling components and/or other attachments on a unit.
Boom
Specific requirements for extendable boom platforms. Includes:
- daily lift control tests
- unauthorized belting off locations
- authorized & unauthorized work positions
- harness and lanyard usage
- attachment boom and bucket load limits
- parking, stabilization, movement prohibition
- etc
OSHA 1926.453
Specific requirements for Vehicle-Mounted Elevating and Rotating Work Platforms has a general requirement for maintaining clearances while operating an aerial lift around electric power lines, depending on the line voltage.
OSHA 1910.67
Contains general responsibilities of the owners and users, inspection and testing classifications (frequent and periodic), inspection item lists, and maintenance and frequency of maintenance guidelines.
ANSI 92.2
Minimum clearance from power line voltage: 300V or less
avoid contact
Minimum clearance from power line voltage: Over 300V, not over 750V
12 inches
Minimum clearance from power line voltage: Over 750V, not over 2kV
18 inches
Minimum clearance from power line voltage: Over 2kV not over 15kV
24 inches
Minimum clearance from power line voltage: Over 15kV, not over 37kV
36 inches
Minimum clearance from power line voltage: Over 37kV, not over 87.5kV

Name the three safety organizations that dictate the specific regulations regarding working with an aerial lift vehicle.
OSHA 1926.453
OSHA 1910.67
ANSI A92.2
What determines the minimum allowed distance from the conductive part of an aerial lift to an energized electric power line?
Power Line Voltages
A device that protects against electric shock if a technician comes into contact with a live/hot wire and a path to ground that would result in a current through his/her body.
Ground Fault Circuit Interrupter (GFCI)
If the _____ is low or poor condition the stability of the aerial lift vehicle is severely affected.
tire pressure
Can deplete the oil level in the reservoir and damage the pump.
Hydraulic Oil Leak
The Frequent Inspection and Test is designated in:
ANSI 92.2
The Maximum permissible weight of the unit, including the vehicle plus all fluids, cargo, optional equipment and accessories.
Gross Vehicle Weight Rating
To comply with the Department of Transportation (DOT), any vehicle with a Gross Vehicle Weight Rating (GVWR) greater than or equal to 26,001 lbs, requires a _____.
Commercial Driver’s License (CDL)
Properly evaluate the _____ prior to setting up and operating an aerial lift vehicle to prevent and avoid serious injury or death.
work site
Reduces stability
Places additional stress on rotation system
Requires extra precaution to avoid overturning vehicle
Parking on a slope
