Electrical Hazard
Minimum Safe Approach Distance
An EPV is an all metal NOT ELECTRICALLY INSULATED, ae rial work plat form. DO NOT op er ate it near
ELECTRICAL con duc tors. Re gard all con duc tors as be ing en er gized. Use the ta ble and il lus tra tion be low
to de ter mine safe clear ance from elec tri cal con duc tors. (Ta ble 1 and Fig ure 3, be low, are from ANSI/SIA
A92.6–1990 Stan dard, re printed with per mis sion of Scaf fold In dus try As so ci a tion.)

Danger:
- Do not allow machine personnel or conductive
materials inside prohibited zone.
- Maintain M.S.A.D. From all energised lines and parts
as well as those shown.
- Assume all electrical parts and wires are energised
unless known otherwise.
- Diagrams shown are only for purposes of illustrating
Caution:
