Hydro One Limits Of Approach

Avoid storing material or equipment under power lines. Explain methods of verifying operating voltages identify the reasons for the limits of approach determine the safe limits of approach for various workers and equipment indicate where to find information on the safe limits of approach relate how safe limits of approach are measured. Avoid touching them or coming too close.
hydro one limits of approach

750 to 150000 volts 3 metres.

Hydro one limits of approach. Proximity is defined by the following limits of approach and does not apply to apparatus that is designed built and installed to be intrinsically safe for human touch a within 3 metres 10 feet of energized apparatus above 750 v to 150 kv. 250001 volts 6 metres. The limits of approach are designed to eliminate the possibility of a flashover between the live electrical component and your body. The limits of approach apply only to bare conductors and not to insulated conductors.

Even power lines carrying less than 750 volts can be hazardous. The safe limits of approach are stated in the occupational health and safety act and also in hydro one safety rules. Limits of approach for personnel in certain situations specially trained personnel will work on live apparatus and may actually touch energized conductors. B within 45 metres 15 feet of energized apparatus above 150 kv to 250 kv.

These workers are insulated from ground and must still maintain the restricted limits of approach between themselves and any grounded structures around them. Upon completion of this module you will be able to. Limits of approach limits of approach for equipment. 150001 to 250000 volts 45 metres.

There are defined distances or limits of approach that have been established by ontarios occupational health and safety act and hydro one to help ensure your safety. In this topic you will learn how to apply these safe limits of approach when working near live equipment.
