Approach boundaries
Limited Approach Boundary Is the closest distance that an Ordinary Electrical Person can approach exposed energised conductors without escort. An Ordinary Electrical Person may be escorted within the Limited Approach Boundary by a Qualified Electrical Person but may never enter the Restricted Approach Boundary. All persons in the Limited Approach Boundary must wear the minimum PPE for electrical work. All tools that enter the Limited Approach Boundary must be insulated for the equipment ’s voltage. Restricted Approach Boundary The Restricted Approach Boundary may only be entered by a Qualified Electrical Person. All parts of the Qualified Electrical Person that enter the Restricted Approach Boundary must be insulated from the equipment ’s voltage. An Energised Electrical Work Permit is required to enter the Restricted Approach Boundary, unless performing switching or taking measurements.
Minimum arc flash PPE
Minimum: - Safety glasses
- Non-melting clothing (including underwear) with long sleeves and long pants (small parts of melting materials are acceptable but should be reduced to the minimum possible, ideally eliminated, for example elasticated waistbands) - Safety shoes with non-melting materials (acceptable exceptions are the sole and shoelaces)
The requirements for tools to be used for testing for the absence of voltage
Have limited functionality and be with fixed test leads. Or;
Be multi-meters with an audible alert function to warn the user in the event the meter function selector and test leads positions are not compatible. Test probes must be selected to match the physical requirements of the test point and be in accordance with local electrical regulatory requirements. Non-contact voltage detectors are for use only with Non-contact voltage portals or for double checking that the Lockout boundary is in Electrically Safe Work Condition. Non-Contact Voltage Detectors are not allowed for Test-Before- Touch verification. Mandatory when performing energised work (in extraordinary circumstances under an approved special permit) that requires using the tools inside the Limited Approach Boundary or Restricted Approach boundary.
When to use insulated (voltage-rated), approved tools?
