ELECTRICAL SAFETY
I.I KNOW ELECTRICAL HAZARDS
1.1.1 IDENTIFY THE HAZARDS IN WIRING
INSTALLATION
1.1.2 IDENTIFY THE HAZARDS IN FAULTY
PARTS

1.1.1 IDENTIFY THE HAZARDS IN WIRING INSTALLATION
KNOB AND TUBE WIRING
 Knob and tube is very old wiring, and in many cases has deteriorated,

cracked, or is missing insulation, which can lead to fires.

Cloth Cable Wiring
Cloth cable wiring may contain asbestos and poses

a serious health risk. It is seldom grounded
properly.

Aluminum Wiring
Aluminum wiring is no longer permitted for use in

new installations by most jurisdictions. It is also
seldom grounded properly.

Ungrounded Wiring
Grounding of an electrical receptacle prevents

painful or even deadly electrical shocks when
electricity flows through an improper path.  Every
home electrical system should have some type of
grounding. 

1.1.2 IDENTIFY THE HAZARS IN FAULTY PARTS

RISK
Electric shocks from faulty electrical equipment may

also lead to related injuries, including falls from
ladders or other elevated work platforms. Other
injuries or illnesses may include muscle spasms,
collapse and unconsciousness.

 Poor electrical installation and faulty

electrical appliances can lead to electric shock
to others at or near the workplace.

REMEDY
Remove damaged, unsafe electrical

equipment or cords from the workplace
Use battery operated tools rather than mains
power tools where possible

Don't overload power sockets. Use power

boards not double adaptors
Ensure electrical equipment is in good
working order by testing and tagging
