      or leads.
Consideration should be given to eliminating the use of metallic, wire reinforced or otherwise conductive ladders; these items should not be used in close proximity to equipment where an electrical hazard may result from their use. These types of ladders should be avoided for any
kind of electrical work.
Other effective risk control measures may include:
    * identifying if there are exposed energised parts nearby. In this situation, risk control measures such as de-energising, fitting covers, using a safety observer, or a combination of these, should be considered
    * employing safe work practices, including:
       * two or more people carrying long devices in switchyards and switchrooms in a position below shoulder height
       * two people handling extension ladders in windy conditions
       * restraining ladders using head ropes or footropes, or both
       * if practicable—using a platform-style step ladder
    * if conductive scaffolding is used within high-voltage enclosures or in situations where there is induction, bonding the structure to the earthing system. Depending on the construction of the scaffold, a number of sections may need to be bonded to ensure an equipotential state.

9.3              Insulating barriers and insulating mats
Insulating covers and mats used for electrical safety purposes should comply with AS/NZS 2978:1995 Insulating mats for electrical purposes.
Insulated barriers should be of suitable material to effectively separate electrical workers from adjacent energised equipment.
Insulated covers and mats should be visually inspected for possible defects before and after each use.

9.4              Test instruments
The tools, testing equipment and PPE for testing and fault finding must be suitable for the work, properly tested and maintained in good working order.
Workers carrying out electrical testing must be appropriately trained and competent in test procedures and in the use of testing instruments and equipment, including:
    * being able to use the device safely and in the manner for which it was intended
    * being able to determine, by inspection, that the device is safe for use, for example the device is not damaged and is fit for purpose
    * understanding the limitations of the equipment, for example when testing to prove an alternating current circuit is de-energised, whether the device indicates the presence of hazardous levels of direct current
    * being aware of the electrical safety implications for others when the device is being used, for example whether the device causes the electric potential of the earthing system to
      rise to a hazardous level
    * knowing what to do to ensure electrical safety when an inconclusive or incorrect result
      is obtained.

Checks carried out on test instruments
Test instruments that are to be used or connected to electrical equipment should meet the following conditions:
     * be suitable for the work in
