Part1 Task 3

ICC site at Mattakkuliya

Section of construction site- Building construction area

Name of the persons- Date-

Description of work- Walking around the site while working

Activity Hazards

Walking outside the building area Due to uneven ground

conditions there will befalling accidents occur

There were timber partwith full of nails just

outside the buildingarea.

Possibility of slip andfall because, There wer

some muddy areas withno suitable access to

walk.

Stepping on nails and

sharp objects.

Description of work- When doing excavation activities and earthwork activities

Activity Hazard

Working without using safety shoes Legcan get hit bysharpworkingequipmen

s.

Leg canget bite by any

kind of an animal.

Stepping on nails and

sharp objects.

Any kind of objects ca

fall on to the foot area the workers.

Working in the very near area where excavation machinery are working Accidents can occur duto the machinery

operating large mobile equipment, such as drillers, air hammers, pile drivers,tractors, graders, excavators, earth-moving equipment, and other large

machinery.

Whole-body vibration

Description of work- Arranging the reinforcement for a column onthe 3rd floor on a scaffolding (working at heights)


2/13

Activity Hazards

Working at heights (more than 10-15ft from the nearest floor.) Possibility of fallingfrom heights

Working on a scaffolding Possibility of fallingfrom one side (some

sides of the scaffoldingwere not covered in the

site)

Possibility of collapsin

the scaffolding (somescrews of the

scaffoldings were nottightened well enough

the site)

Possibility of falling

objects to the nearest

floor and damage thepeople in that floor(some sides of the

scaffolding were notcovered in the site)

In some scaffoldings,the foot area (where

workers stand) was notbuilt strongly. (Serious

accidents can occur incase of falling)

Some vehicles wereparked near the ground

area, where thescaffoldings were

built.(In case of vehiclehit the scaffoldings,

there will be seriousaccidents)

When fixing the scaffolding Single worker trying toget the parts of the

scaffolding to the top o

the scaffolding to fix itwithout any support orprotection. (In case of a

problem with regardingthe balance, there will

be serious accidents)

Description of work- When doing steel work


3/13

Activity Hazards

Working with the machines which have not guarded properly Can damage leg or hanby engaging with the

belt.

Working with damaged welding masks Can be harmful for the

eyes of the workers.Working with equipments which includes damaged wires. Electric shocks can

occur

Using electric equipments without Plug tops. Electric shocks can

occur in case of a loosconnection.

Working around the area where the welding plant wires have not being arrangedproperly.

Therell be fallingaccidents if someones

leg gets tackle with thewires.

And also, therell be

electric shocks occur ifsomeones leg getstackle with the wires.

Working around the area where some electric equipments were kept in some

dangerous places.

Electric shocks or even

burning injuries canoccur if someone steps

into an equipment.

Working around the area where fuel and chemicals are kept nearby to the

welding equipments.

Huge fire situation can

occur if a spark getsnear to that area.

Welding in a closed area welders receiving seve

arc burnsWorkers around thatarea could receive

severe arc burns.

Due to the compressed gass cylinders which are stored near to that particular

area.

hazardous if theresdamage to cylinder

valves, and because of

the risk of explosion orflashback (compressedgas cylinders need to beequipped with reverse

flow check valves toprevent flashback).

Description of work-When working with the electricity.

Activity Hazard

When working with the electricity. Electric shocks can

occur due to Static fromthe rubbing (friction

effects) of plastics and


4/13

from clothing made

from wool, wool blendnylons and polyvinyl

Electric shocks canoccur due to Personal

effects (e.g. rings,jewelry, cigarette

lighters, matches,hearing aids, mobile

phones and pagers,transistor radios and

similar);

Huge fire situation can

occur due to using ofgas flame near exposed

electrical conductors (a

flame is a conductor);Huge fire situation canoccur due to Obstacles

to getting the equipmenswitched off;

Huge fire situation canoccur due to lack of

ventilation leading touncomfortable, hot and

humid workingconditions;

Huge fire situation andalso,electric shocks can

occur due to Voltagesbetween live exposed

conductors andsurrounding metal

framework

Electric shocks can

occur due to electrictools and equipment

(e.g. hand lamps, drills

saws, torches and testinstruments);


5/13

Description of work-When doing false work

Activity Hazards

heavy, frequent, or awkward lifting Various body injuries including back pain.

Using improper jack andsupporting materials

supporting materials can be fall to the persons whoworking in the site.

Not selecting the proper materialsand systems according to the given

case.

Can collapse the full false work and form work structure.

Description of work-When doing formwork

When walking on the formwok Possibility to slip and fall.Can get collapse

Can get tackle becouse of the gaps between the

scaffoldings.

Can get hurt by stepping on to heequipments on the

scaffolding.

Description of work-When working with multiple source electricity systems (confined areas)

Electrical testing in confined area with explosive gas

mixture, fumes, vapor or dust which is inadequatelyventilated.

Working in situations where condensation, spillage,drainage or seepage occurs and results in wet

surroundings

Pipes, sewers, shafts, ducts, and similar structures.

Voltages between live exposed conductors and

surrounding metal frameworkVoltages between live exposed conductors and thesurrounding environment (including metalwork, damp

situations, other conductive surfaces and persons nearby).

General work activities (e.g. welding, cutting, brazing,

using hand saws, drilling of all types, hammering andchiseling);

Hot metal surfaces due to drilling, grinding welding, etc.


6/13

Excavation associated with electrical work;

Description of work-When driving vehicles in the site

Activity Hazards

Construction vehicles entering /

leaving traffic.

Vehicles striking services and obstructions

Site staff crossing live carriageway Can get hit by the running vehicles

Overturning vehicles (due toslpoes, uneven ground)

Workers who are opperating the vehicle can get hurt.

When reversing vehicles Vehicles or their loads striking people,

Unsafe loading and transportation of

materials on vehiclesPeople can get stuck by the vehicle or by the load.

Rough access roads Vehicle can get stuck and therefore the workers who areworking with the vehicle can get hurt.
