Electrocution Hazards

The MHP is an all metal boom ae rial work plat form
and is not elec tri cally in su lated. Do not op er ate it
near electrical con duc tors. Re gard all con duc tors
as be ing en er gized. Do not op er ate out side dur ing
a thun der storm.

Minimum safe approach distance

Min i mum safe ap proach dis tances to energised
power lines and their as so ci ated parts must be ob -
served wile op er at ing the MHP.

Figure 1. - Minimum Safe Approach Distance

The MHP is not electrically insulated. Death
or serious injury can result from contact
with, or inadequate clearance from, an
energised conductor. Do not go closer than
the minimum safe approach distance as
defined by ANSI.

ANSI pub li ca tions de fine min i mum dis tances that
must be ob served when work ing near bus bars and
energised power lines. Fig ure 1 and Ta ble 1 are re -

be given a vi sual in spec tion and func tion test. See
the “Daily In spec tion and Main te nance” chap ter 7,
in this man ual for a list of items to in spect and test.
