Chapter 3 – Safety
Knowledge of the information in this manual, and
proper training, provide a basis for safely operating the
aerial platform. Know the location of all controls and
how they operate to act quickly and responsibly in an
emergency.
Safety devices reduce the likelihood of an accident.
y Never disable, modify, or ignore any safety device.
y Safety alerts in this manual indicate situations where
accidents may occur.
If any malfunction, hazard or potentially unsafe condition
relating to capacity, intended use, or safe operation is sus-
pected, stop aerial platform operation and seek assistance.
The operator bears ultimate responsibility for following
all manufacturer’s instructions and warnings, regulations
and safety rules of their employer and/or any state or
federal law.
Electrocution Hazards
The aerial platform is made of metal components and is
not insulated. Regard all conductors as energized. Do
not operate outside during a thunderstorm.
Minimum Safe Approach Distance
Minimum safe approach distances to energized power
lines and their associated parts must be observed while
operating the aerial platform.
Danger
The aerial platform is not electrically insulated.
Death or serious injury will result from contact
with, or inadequate clearance from, an energized
conductor. Do not go closer than the minimum safe
approach distance as dened by ANSI.
ANSI publications dene minimum distances that must
be observed when working near bus bars and energized
power lines. Table 1 and Figure 3 are reprinted courtesy
of Scaffold Industry Association, ANSI/SIA A92.5.
