CASE STUDY

A group of workers were carrying out palm fruit harvesting workin a plantation when the incident occurred. In the process of cutting thepalm fruit from a tree, the victim accidentally cut into a LV 3x95mm aerialbundle cable. The victim received an electrical shock through thealuminum pole which he had used as part of his cutting tool. Victim diedat the place of incident.

OVERALL VIEW OF CASE STUDY

Electricity requirescomplete path to

continuously flow,normally through

conductor

Shock results whenthe body becomes

part of theelectrical circuit,

current enters onepoint and leaves at

another

Both wires of an energized

circuit

One wire of an energized circuit andthe ground

A metallic part in contact with anenergized wire while the person is

also in contact with the ground

Workers aresubjected to hazard

because of tallequipment

Aluminumpaint rollers

Cranes

Metal ladders

Scaffolds

OVERALL VIEW OF CASE STUDY

Cable line

Employee

Aluminium pole

Palm tree

Electric shock can only occurwhen contact is made

between two points of acircuit-when voltage is applied

across a victim's body

Aground faultis anaccidental connection

between a circuit conductor(aluminum pole) and the

earth (ground)

Special, insulated shoes are made to protectpersons from shock via ground conduction. The

gears have to be clean, dry condition to beeffective.

Though dirt is a poorconductor, it can conduct

enough current to injure or killa human being

EVENTS LEADING TO OCCURRENCE OF INCIDENT

other workers mightnot notice that thevictim had been in

contact with the livecable and causing

the victim in contactfor long enough for

casualty

that could act as aninsulator that limit

the current to avoidelectrical flow to the

ground

That could alertthe victim aboutthe existence of

the cable

Aluminium, agood conductorcaused currentto flow when

workeraccidentally cut

the cable.

victim usedan aluminium

pole as acutting tool

No sign boardor warning

board aroundthat area

distance ofeach worker

from the

other mightbe too far

victim wasnot wearing

proper

personalprotectiveequipment


6/13

EVENTS LEADING TO OCCURRENCE OF INCIDENT

Every worker should be given a brief of safety measures andan instruction to perform emergency treatment before the

paramedic.

The paramedic was taking too much time to arrive to the scene asthe plantation was not equipped with proper emergency exit/road

for this kind of accident.

8/13

RECOGNIZE AND EVALUATE THE HAZARD

Equipment

used topluck thepalm fruit

An aluminum pole used asan equipment to pluck thepalm fruit has no insulator

at the holder

allowed the current to passthrough the workers body,CAUSED the worker to beelectrocuted

Parasiteplants

betweenthe cableline and

palm fruit

Parasite plants surroundingthe cable line and palmfruit had caused sometroubles for the worker topluck the palm fruit thatlead to miss-aim andaccidentally cut the cable

Properused of

PPE

The worker himself didnot wear properprotective equipmentsuch as proper glove andboot

PP

Ehas its own resistivityto limit the flow of current


9/13

CONTROL THE HAZARD


10/13

CONTROL THE HAZARD

Aware of anypossible hazard

around the workingarea and take aserious safetyconsideration

Followsafety

proceduresgiven by the

employer

Wear PPEprovided by

employer

EMPLOYEE


11/13

SUGGESTED WORKPLAN FOR SAFETY PROCEDURES

Wear personal

protective equipmentsuitable for the job

Always work in pairs

with maximumdistance from eachother is 5 meters

Indicate location of

any power cables inthe plantation beforestarts working

Keep safe distancefrom the power

cables

Checks allequipments used are

in good condition

Starts to work onlyafter all potential

hazard is identified

To avoid the incident from happen again, a new design of work procedureshould be followed by the workers for their safety


12/13

SUGGESTED WORKPLAN FOR SAFETY PROCEDURES

Wear all personal

protective equipment

Do not use anyharvesting

equipment that useselectric conducting

material as a pole

Do not harvest thepalm oil that is lessthan 1 meter from

the power lines

Put signs around thepower cables path to

alert all personals

All workers mustattend work safety

course and CPRtraining

Workers must beinformed of the

location of first aid kitand important

number to contactduring emergency

CONCLUSION

No one can replacea worker or loved

one that has died orsuffered theirreparable

consequences of an
