Electrical Safety Hazards can also be presented through a damaged or failed Insulation.An Electrical insulation here refers to the material covering (plastic, rubber, etc) used to covered electric wires or cables to prevent them from:

* Contacting one another;

* Contacting other electrical installations/ panels

* Contacting people.

When these insulations are damaged, they can allow the passage of current into neighboring objects that come in contact with them, thereby presenting several causes of electrical safety incidents within the workplace.

Causes Of Electrical Insulation Failure

i. Cuts or Abrasion from sharp objects or edges

ii. Heat from electrical overload on the wires beneath the insulation

iii. Deformation from heavy objects resting on the insulation.

iv. Inadequate equipment cooling can cause overheating, affecting the insulation

v. Aging

How To Prevent Failed Insulation Electrical Hazards

a. Keep all cables away from the gangways (to, among other things,avoid trampling by feet or mobile machineries).

Use cable trays to safely stow away all cables instead.

b. Periodically inspect Portable Tools’ cables to ensure integrity of cable insulation.

c. Do not overload your extension cables or other circuitry. Use Circuit Breakers or GFCI (Ground Fault Circuit Interrupters) to guard against overloads-with the attendant overheating of the insulation.



Wet conditions such as water or moisture filled floors, wet clothing, perspiration, or wet surfaces lower your electrical resistance and can provide an easy path for current to flow to the ground. This becomes hazardous because current can then flow through your body- causing an electrical shock.

Common Causes Of Wet Conditions Electrical Hazards

a. Water spills on the body or on the floor

b. Wet Clothing

c. Perspiration

d. High level of humidity

e. Rainfall/ wet atmospheric conditions.

How To Prevent Wet Conditions

i. Do not use wet clothing or PPE while working on energized units.

ii. Suspend all electrical works whenever a rainstorm begins or where wet conditions exist. Resume only when conditions change to prevent injury or electrocution.

iii. Ensure Electrical panels and enclosures are properly closed/sealed to prevent water ingress.
