Q

PHILOSOPHY

A

What we are going to do to meet the policy! give safety from the system and use hierachy of controls; make available, establish safe conditions,authorise start of work, receive authority to start, cancel authority, restore system to normal.

Q

Rule 2

A

Approach to HV conductors and insulators
Nothing can approach within safety distance
When POI established conductors are still charged only voltage measuring devices and earthing devices can approach.
When POI’s and PE applied approach is allowed under an appropriate safety document 1M must be maintained during the application of portable earths.

21
Q

R3

A

Safety precautions for work on or near to HV equipment
SAP assess means of achieving SFTS, if he can limit the area he will give instructions in writing, where necessary an LAC will be issued.
Where limiting the area is not enough an outage is required.
CPO-SSC-CPS-ESTABLISH SAFETY PRECAUTIONS WITH AP conditions in place for OHL PFW to be taken out.
Where drain earths are needed for charged conductors, they shall be issued with an appropriate safety document and earthing schedule.

22
Q

R4

A

Safety precautions for work on or near LV equipment

23
Q

R5

A

Safety precautions for work on or near Mechanical equipment

24
Q

R6

A

Operation of equipment

No undue delay or prearranged time scales

25
Q

R7

A

Demarcation of work areas
Work area clearly defined and protected physically where necessary.

SAP duty to prep and enter all correct relevant details.
Shall be prepped before contacting the CPS.

Reads and understands the SD.
Can ID the equipment (Tech data sheets/ops diagrams).
Conversant with all further precautions (IGDD etc).
SAP to issue an earthing schedule.
For work on down leads a physical walk to witness safety precautions with the CP shall be carried out.
