SCAFFOLDING

Hazards and Solution


4

Construction Safety

• Nearly 6.5 million people work at approximately 252,000 construction sites across the nation on any day and the fatal injury rate for the construction industry is higher than any other industry

• The main injuries in the construction field are due to following factors.

• Falls• Trench collapse• Scaffold Collapse• Electric shock


5

SCAFFOLDING

A temporary structure on the outside of the building , made of wooden planks and metal poles , used by workmen while building ,repairing , or cleaning the building.


6

TYPES OF SCAFFOLDING SUPPORTED SCAFFOLDING

Supported scaffolds consist of one or more platforms supported by outrigger beams, brackets, poles, legs, uprights, posts, frames, or similar rigid support.

• .


7

SUSPENDED SCAFFOLDING

Suspended scaffolds are platforms suspended by ropes, or other non-rigid means, from an overhead structure.


8

CANTILEVER SCAFFOLDING

The Cantilever Scaffold Tower is most commonly used to work over existing obstacles on the ground, such as stairs, porches, machinery or anything else that won't budge.


9

ROLLING SCAFFOLDING

• A scaffold is a temporary structure, usually made of metal tubing, which provides support for workers and materials used in construction and it have wheels that give them mobility.


10

HAZARDS IN SCAFFOLDING

• Usually hazards occur when things or the apparatus is not used properly.

• Similarly hazards also occur in the use of the scaffolding

• When scaffolds are not used properly hazards occur which are fall hazards or the electric shock e-t c


11

HAZARDS (cont.)• The main hazard is falling from height In falling fatalities Globally about 60% of the fatalities occur

when person fall from a height less than 5 meters because there is less reaction time.


12

HAZARDS (cont.)

• The second main hazard is electric shock If scaffolding is made of steel and there laying a

naked electric wires there is a risk of electric shock because whole of scaffolding become conductor as steel is a good conductor of electricity


13

Hazards (cont.)

Bad planking is also a hazard to watch out when using scaffolding.

Getting stuck to falling tools and equipments from scaffolding is also a hazard.

Further results of failing of scaffolding are disturbing budge to cast ratio, delays , disputes and claims etc.


14

Importance of life of Human being

• Allah Kreem says in Quran ,

“Whosoever kills an innocent human beings it shall be as if he has killed all mankind, and

whosoever saves the life of one, it shall be as if he had saved the life of all mankind”

Qura’n 5:32


15

Solutions

There are many solutions to become safe from hazards of scaffolding…

• Scaffold must be sound , rigid and sufficient to carry its own weight plus 4 times the maximum intended load without setting or displacement.

• Unstable objects such as barrels , boxes, loose bricks or concrete blocks must not be used to support scaffolds.


16

Solutions• Scaffold must not be erected , moved , dismantled or altered

except under the supervision of a competent person.• Scaffold must be equipped with guardrails and midrails .

• Scaffold accessories such as braces , brackets , trusses ,screw legs or ladders that are damaged must be changed timely .


17

Solutions• Work area should be clearly defined.• Warn signs should be used.

• Components should be vertically aligned with spirit level .


18

Solutions

• Foundation should be firm and leveled.• Position of sole plate and base plate should be correct

. Leveled ground.

• Try to start at highest point building area .


19

Solutions

• Check the distance from the building after a proper interval of time. Distance should be moderate .

• Pins and badges should be fixed properly.


20

Solutions

• Brocken and damaged components should be set outside.

• Stairs should be provided in non working area of scaffolds.
