611 Minimum distances between materials, protected aerial lines and protected infrastructure

(1) A person must not place any flammable material or allow flammable material to remain closer than 3000 millimetres in any direction from a wall or fence of any substation or switch yard that forms part of protected infrastructure.

(2) A person must not place any flammable material or allow flammable material to remain vertically below a protected aerial line.

(3) A person must not place any flammable material or allow flammable material to remain so that, at any time, the flammable material is closer than the relevant horizontal distance specified in Row A of Table 611 from any point of the vertical projection below a protected aerial line.

(4) A person must not place any material or allow any material to remain so that, at any time, the material is closer than the relevant horizontal distance marked "h" specified in Row B of Table 611 from any point of the vertical projection below a protected aerial line unless the material is no closer vertically below the line than the vertical distance marked "v" specified in Row B of Table 611.
