[RE-wrenches] Conduit across walkways

If it is in a walking traffic area of concern, build a short step  or steps over the conduit. Use unistrut and have it sitting (ballasted perhaps so it won't move) on dura blocks. 
Google "Cooper B-line" They have a line of strut products for just about everything and you can probably get some good ideas from them.

Is there anything in the NEC or OSHA that requires some type of step or protection for conduits in access walkways?  I am concerned with a scenario where the conduit is covered with snow and becomes an even bigger trip hazard and potential source of damage to the DC conductors.
