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 environment.
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).
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 mobility and
support for the booms.
elevating assembly
– the assembly located between the chassis and the
platform which is used to raise and lower the platform.
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. Although federal regulations, OSHA, ANSI, and Snor-
kel do not require the use of additional fall protection beyond the platform
guardrails on scissor lift aerial platforms, local, state, or employer rules may
require their use.
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 per-
sonnel from falling.
hazardous location
– any location that contains, or has the potential to con-
tain, an explosive or flammable atmosphere as defined by ANSI/NFPA 505.
level 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.
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 permitted 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 platform.
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.
outrigger
– a mechanical tip-over prevention structure consisting of a
hydraulically extended leg used to make ground contact to aid in stabilizing
the machine.
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 anchorage 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 plat
-
form 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 platform as
specified by the manufacturer.
safety prop
– a bar that when properly positioned mechanically prevents
the platform from lowering.
stow
– to place a component, such as the platform, in its rest position.
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.
unrestricted rated work load
– the maximum designed carrying capacity of
the aerial platform allowed by the manufacturer in all operating 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 travel that the platform may be positioned in.
working height
– platform height plus six feet.
