Under section 38 of the WORK HEALTH AND SAFETY ACT 2011. The code of practice makes specific reference to the use of lead stands

“Arrange electrical leads so they will not be damaged. So far as is reasonably practicable, avoid running leads across the floor or ground, through doorways and over sharp edges, and use LEAD STANDS or insulated cable hangers to keep leads off the ground. In many heavy industries, cable protection ramps are used to protect cables.”
