Appendix A  – Glossary

aerial platform

 – a mobile device that has an adjustable position

platform, supported from ground level by a structure.

ambient temperature

 – the air temperature of the immediate environ-

ment.

ammeter

 – an instrument for measuring the strength of an electric

current in amperes.

authorized personnel

 – personnel approved as assigned to perform

specific duties at a specific location.

base

 – the relevant contact points of the aerial platform that form the

stability support (e.g. wheels, casters, outriggers, stabilizers).

boom

 – a movable cantilever beam which supports the platform.

center of gravity

 – the point in the aerial platform around which its

weight is evenly balanced.

chassis

 – the integral part of the aerial platform that provides mobil-

ity and support for the booms.

fall restraint

 – a system that is used while working on a boom lift within

the boundaries of platform guardrails to provide restraint from being
projected upward from the platform. This system includes a harness or
belt, lanyard, and a lanyard anchor. Federal OSHA, ANSI, and UpRight
require the use of additional fall protection beyond the platform guard-
rails on boom supported aerial platforms.

floor or ground pressure

 – the maximum pressure, expressed in pounds

per square inch, a single wheel concentrates on the floor or ground.

gradeability

 – the maximum slope that the aerial platform is capable

of travel.

guardrail system

 – a vertical barrier around the platform to prevent

personnel from falling.

hazardous location

 – any location that contains, or has the potential

to contain, an explosive or flammable atmosphere as defined by
ANSI/NFPA 505.

intermediate boom

 – a telescopic boom section that extends and

retracts from within the main boom. The intermediate boom is be-
tween the base, or lower most section of the main boom, and the tip
boom.

jib

 – an articulating boom attached to the tip boom which increases

the overall boom reach.

l

evel sensor

 – a device that detects a preset degree of variation from

perfect level. The level sensor is used to sound an alarm if operating
on a slope greater than the preset value.

l

ower controls

 – the controls located at ground level for operating

some or all of the functions of the aerial platform.

main boom

 – a boom assembly located between the turntable and the

platform.

manufacturer

 – a person or entity who makes, builds or produces an

aerial platform.

maximum travel height

 – the maximum platform height or the most

adverse configuration(s) with respect to stability in which travel is per-
mitted by the manufacturer.

maximum wheel load

 – the load or weight that can be transmitted

through a single wheel to the floor or ground.

Minimum Safe Approach Distance

 – the minimum safe distance that

electrical conductors may be approached when using the aerial plat-
form. Also called M.S.A.D.

operation

 – the performance of any aerial platform functions within

the scope of its specifications and in accordance with the manufacturer’s
instructions, the users work rules, and all applicable governmental
regulations.

operator

 – a qualified person who controls the movement of an aerial

platform.

personal fall arrest system

 – a fall protection system that is used

while working on an unprotected edge (such as a roof top with no
guardrail). This system includes a harness, lanyard or other connecting
device, a fall arrestor, an energy absorber or decelerator, an anchor-
age connector, and a secure anchorage such as a building beam,
girders or columns. An aerial platform is not a fall arrest anchorage.

platform

 – the portion of an aerial platform intended to be occupied

by personnel with their tools and materials.

platform height

 – the vertical distance measured from the floor of the

platform to the surface upon which the chassis is being supported.

prestart inspection

 –  a required safety inspection routine that is

performed daily before operating the aerial platform.

qualified person

 – a person, who by reason of knowledge, experience,

or training is familiar with the operation to be performed and the
hazards involved.

rated work load

 – the designed carrying capacity of the aerial plat-

form as specified by the manufacturer.

stow

 – to place a component, such as the platform, in its rest position.

tip boom

 – a  telescopic boom section that extends and retracts from

within the main boom. The tip boom is nearest the platform.

turning radius

 – the radius of the circle created by the wheel during a

360° turn with the steering wheels turned to maximum. Inside turning
radius is the wheel closest to the center and outside turning radius is
the wheel farthest from the center.

turntable

 – the structure above the rotation bearing which supports the

main boom. The turntable rotates about the centerline of rotation.

unrestricted rated work load

 – the maximum designed carrying ca-

pacity of the aerial platform allowed by the manufacturer in all oper-
ating configurations.

upper controls

 – the controls located on or beside the platform used

for operating some or all of the functions of the aerial platform.

wheelbase

 – the distance from the center of the rear wheel to the

center of the front wheel.

working envelope

 – the area defined by the horizontal and vertical

limits of boom travel that the platform may be positioned in.

working height

 – platform height plus six feet.
