Safety Measures for Temporary Electrical Wiring

Temporary Electrical Wiring is made especially in the start of the construction and for a temporary electrical power requirement. As these having many hazards associated with it, the following measures to be ensured.

i) All the Temporary electrical wiring is to be authorized with Permit to Work, it is permitted only during the period of construction, remodeling, maintenance, repair, demolition and similar activities. It shall be removed immediately upon completion of the purpose for which the wiring was installed.

ii) The temporary electrical wiring shall be installed in such a manner that it is not subjected to physical damage. The wiring to be protected from mechanical damage and any other form of damage. The live wiring core should not exposed at any cost.  The sharp corners and projections should be avoided while laying the cable. The wiring shall be adequately protected while passing through the door ways or other pinch points.


BASIC MACHINE GUARDING SAFETY


iii) The metallic case of temporary lighting & Lighting Distribution Board (DB)s to be separately earthed in two places.

iv) Proper marking to be done. Precaution to be taken so that temporary electrical cable laying at worksite should not interfere with normal Human and Equipment & machineries movement creating hazards like electrocution, electrical fire, Slip/ Trip/ Fall etc.

v) Earth Leakage Protection - All hand-held tools (eg hand held drill machine, hand held grinder etc) shall be protected through 30mA earth fault protection (RCBO etc) with 200 milli Seconds fault clearance time and Overcurrent setting as per Equipment requirement.


SAFETY DURING DEMOLITION / DISMANTLING


vi) All Portable equipment/ tools which are not hand held (like submersible pumps, dewatering pump, 415V & 240V welding set etc.) shall be protected through 100mA earth fault protection (RCBO etc) with 100 milli Seconds fault clearance time and Overcurrent setting as per Equipment requirement.

vii) Ensure Periodic checking of RCBO by trip test

viii) Earth leakage protection is not compulsory for double insulated tools, but its suggested to provide the same.
