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. Never disable, modify, or ignore any
safety device. 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 suspected, 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.
The aerial platform is not electrically
insulated. Death or serious injury can result
from contact with, or inadequate clearance
from, an energized conductor. Do not go
closer than the minimum safe approach
distance as defined by ANSI.
ANSI publications define 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 A92.6, page 26.
