Section 1 - About Your Aerial Platform
Electrocution Hazard
This aerial platform is not electrically insulated. Maintain a Minimum Safe Approach Distance (MSAD) from
energized power lines and parts as listed below. The operator must allow for the platform to sway, rock or sag.
This aerial platform does not provide protection from contact with or proximity to an electrically charged conductor.
Per ANSI A92.6-2006 8.10(7)
"The operator shall perform only that work for which he or she is qualified, in compliance with all applicable safety
related work practices intended to prevent electric shock covered by the Code of Federal Regulations (CFR)
1910.333. The operator's level of competence shall be established only by persons qualified to do so. Operators
shall maintain the appropriate minimum approach distance (MAD) from energized power lines and parts covered
by CFR 1910.333 (c)."
Unqualified persons must maintain a minimum approach distance of 10 feet from any energized power line up to
50 kV. Energized power lines over 50 kV require a greater minimum approach distance to be maintained. Refer to
CFR 1910.333.
As per CSA B354.2-01
"The operator shall maintain the minimum safe approach distance (MSAD) from energized conductors at all times
in accordance with the authority having jurisdiction."
