They aren't intended to provide technical specifications. Figure eight shouldn't be supposed to supply technical specifications for erecting scaffolding as it is not possible to indicate all particulars. A PCBU ought to use the hierarchy of controls (Figure 3) to work out the best management measures to minimise the risk. As well because the insulation choices described in Section 5 of this guide, using non-conductive scaffolding or insulated elevating work platforms can help to minimise risk. Figure eight reveals how near the line scaffolding or any other short-term construction can be positioned if the property proprietor has provided written consent (see Section 10 of this guide). Side One might embrace information from the Close Approach Consent Form signed by the property proprietor. A detailed Approach Consent Form is a method to acquire consent. We recommend that MADs are used in combination with a number of different management measures. If greater than four m: work can begin.

People whose lives, work or everyday activities might be affected might need to arrange an alternate non permanent supply of electricity. An engineering research is required before constructing a permanent building (or other construction) that can be located close to an overhead line. Tiger tails (see Figures 5, 6 and 7) present mechanical and environmental protection as well as giving a visible reminder that the overhead line is shut. The notice needs to be straightforward to see and read. If mobile plant is likely to be used near a low voltage overhead electric line, the owner or operator of the plant should fix an approved warning notice in an apparent place as close to as practicable to the operator’s place. A physical barrier resembling a hoarding - with a warning signal - could possibly be put in place to stop employees getting nearer than 0.5 m to the overhead line. In addition to sustaining a MAD, we expect a mixture of management measures to be put in place to minimise the chance of electric shock. However a risk evaluation ought to nonetheless be carried out and management measures put in place. This guide provides data on the way to handle the chance of electric shock while work is being executed close to a live low voltage overhead electric line.

Isolation is momentary - for a specified time period while work takes place. When the electricity supply has been isolated, at all times verify that there is no such thing as a alternative source of electricity to the property that might enable an electrical backfeed to occur whereas work is being achieved. The property proprietor should get recommendation from a reliable electrical worker earlier than giving written consent. Always get advice from a reliable electrical worker before work begins close to a low voltage overhead electric line. Workers must have the ability to have a say on any health and safety issues that would affect them, and their strategies on how to improve health and security at work should be thought-about. The worker doesn't have consent to work any nearer to the overhead line. If written consent isn't given, the roofer cannot work less than 4 m from the overhead line. Without written consent from the property proprietor, workers must maintain a MAD of at the very least four m from the overhead line.

If a person must work less than 0.5 m from the overhead line, then the electricity supply to the property must be remoted. If work must happen near a low voltage overhead electric line and isolating the electricity provide just isn't moderately practicable, then the worker’s body, their instruments and their gear have to be saved a safe distance away from the overhead line. If isolating the electricity supply to a property just isn't potential, danger have to be minimised as far as is moderately practicable. ‘Isolate’ means to disconnect a property’s electricity provide from the electricity distribution strains so that the low voltage overhead electric line to the property is now not stay. Note: Seek permission from the electricity distributor before carrying out work close to excessive voltage overhead electric traces or any overhead strains owned by electricity distributors. Figure four reveals the MAD between a low voltage overhead electric line and a worker who has consent to work as much as 0.5 m from the line. Side Two (Figure 11) might be used to document checks on management measures and any adjustments or fixes made. The inexperienced tag insert has two sides.
