Chapter 3 - Safety; Electrocution Hazards; Minimum Safe Approach Distance - Snorkel TB42J Operato's Manual

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 as-
sistance.
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.
A
Danger
The aerial platform is not electrically insulated.
Death or serious injury can result from contact with,
or inadequate clearance from, an energized con-
ductor. 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 A92.5.
