The MEWP is not electrically insulated and does not
provide protection from contact with or proximity to
energized electrical conductors. Follow Section 2.1-1
for the minimum distance to keep between all parts
of the MEWP, occupants, or tools, and the electrical
conductors. Consider MEWP movement and electrical
line sway in minimum distance calculation.
If you need to work nearer than 3 m (10 ft), stop and
apply control measures as determined by a qualied
person with respect to electrical transmission and
distribution.
Obey all the national, state/provincial/territorial and
local safety rules.
2.1-1 Minimum distance from electrical
conductors

STOP and apply control
measures as determined by a
qualied person with respect
to electrical transmission and
distribution.
DANGER
Electrocution hazard. Keep all parts of the MEWP,

hazards leading to death or serious injury.
KNOW all national, state/provincial or territorial, and
local rules which apply to your MEWP and worksite.
MAKE SURE all the safety and instructional labels
are correctly attached on the MEWP in the correct
location. Clean or replace labels that you cannot read.
DISCONNECT and lock out main power disconnect
on the left side of the MEWP when leaving the MEWP
unattended to prevent unauthorized use.
DO NOT wear jewelry or loose
clothing that could become
caught or entangled.
DO NOT allow the
entanglement of ropes, cables
or hoses with the MEWP,
adjacent structures or objects.
Prevent falling from the
platform. Always keep a firm
footing on the platform floor
when working thereon. Do not
climb on the toe-board, mid-rail,
or top-rail. Do not use planks,
ladders, or any other devices
on the platform for achieving
additional height or reach.

DO NOT raise the platform or
operate elevated in windy or
gusty conditions that exceed
the limits specified in
Section 7.8.
DO NOT increase the surface
area of the platform or carry
large surface area items when

considers the subsurface voids such as cellars,
basements, culverts, and pipes.
DO NOT elevate or drive
elevated on a slope. Elevated
driving must be done on a firm,
level surface.
