Electrical Hazard
■ Minimum Safe Approach Distance
An SP is an all metal NOT ELECTRICALLY INSULATED, aerial work platform. DO NOT operate it near
ELECTRICAL conductors. Regard all conductors as being energized. Use the table and illustration below
to determine safe clearance from electrical conductors. (Table 1 and Figure 1, below, are from ANSI/SIA
A92.6–1990 Standard, reprinted with permission of Scaffold Industry Association.)
