PROTECTION 
Over-current Protection:
The basic idea of an over current ( think of over current as current out of control) protection device is to create a weak link in the system that will stop the flow of electricity before the over current can cause any other damage.
Fuses and Circuit breakers open/break the circuit automatically when too much current flows through them.This is design to protect the wiring/equipment from overheating and possible damage. These devices may not and are not intended to protect people; they  protect equipment.

GFCI (Ground Fault Circuit Interrupter)
Used in wet and other risk areas
stops the flows of electricity when there is a difference between current leaving and returning from the outlet. It should be tested monthly; push test button and then the reset button.

POWER EXTENSION CORDS AND POWER STRIPS
Power extension cords and power strips (also known as power taps) are a means to deliver electricity from a power source to a tool or device located where the power source is not. Sometimes the use of such power delivery devices presents overloading factors.The possible consequences of using a power strip should be considered beforehand.Some concerns included :
  •  Damaged or faulty devices posing fire and shock hazards
  • Tripping hazards
Rules to follow:
  • Extension cords are authorized only for temporary use (to do the job at hand, not to remain as a power source for an extended amount of time (days, weeks).
  • Extension cords may not be run through doorways, windows, ceilings, etc. whereby they may be damaged and/or pose tripping hazard
  • Extension cords may not be smaller in diameter then the tool power cords to which they are connected
  • Power strips are authorized only for temporary use, if they are to be used as extension cords
  • Power strips designated as TVSS may be used for longer periods of time for electronic devices only (computers and components, adding machines, clocks, radios) but should not be overloaded or doubled-up
  •  Power strips and extension cords may not be used for appliances (refrigerators, microwaves, coffee pots, portable heaters).
  • All devices and cords must be UL or comparably approved and in good working condition without any signs of damage.
PROPERLY USED POWER STRIP
Strip should not be overloaded.
If intention to use for computer then only computer electrical equipment should be attached. 
cords should be kept neat.
No extension cords should be  attached to power strip.
power strip should be attached directly to wall outlet no extension cord is used.

SOME EXAMPLE OF UNAPPROVED DEVICES:
Not Permitted if:
  • Cord plug with ground prong is missing
  • Damages TVSS rated power strip
  • Adapter enables circuit overloaded
  • Lamp extension cord damaged

RESPONSIBILITIES 
Entire system must be properly bonded and grounded to the earth.
Supervisors are responsible for the system up to the wall outlet (all wiring and outlets)
  • Users are responsible for the condition of plug and cord of equipment .
  •  Properly inspect equipment to ensure plugs and cords ; as these are not damaged.
  • Do not break off third prong or use adopters
  • No Prong = Not grounded
ELECTRICAL WORK:
Electrical work is only to be performed by qualified individuals. Non-skilled workers are not allowed to fix by their own. There is potential risk to fix electricity related work. EEW pertains to qualified electrical workers; they must attend additional . Only New employee orientation training is not enough to perform this task . 
  • Do not take shortcuts and risk the safety of yourself or others. 
  • Know and follow safe work practices and procedures, and if you are unsure…ASK!!
  • Use only appropriate tools and equipment for the work to be done. 
  • Inspect all tools and equipment prior to and during work activity. 
  • The label UL Approved only means the device left the factory meeting certain criteria. 
  • During the time that you may use the device, it may become damaged, therefore exposing yourself and others to hazards. 
Remember: stray electric current caused by damage to a device can shock, seriously injure or kill.
Report any and all unsafe conditions:
  • Receiving an electric shock
  • Sparks
  • Overheating or smoking equipment;
  • Corroded/damaged outlets, switches and junction boxes;
  • Damaged extension cords and equipment power cords that are in use;
  • Exposed wiring, broken plugs, outlets, missing box cover or faceplates;
  • Outlets in damp areas not equipped with GFCI.
  • Stay productive and safe - follow the rules.
