Chapter 3 - Safety; Electrocution Hazards; Minimum Safe Approach Distance - Snorkel S1930E Operator's Manual

Knowledge of the information in this manual, and proper
training, provide a basis for safely operating the aerial plat-
form. Know the location of all controls and how they oper-
ate 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 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 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.
