 INTRODUCTION TO SAFETY

As Civil Engineering is a discipline, which is almost exclusively involved with men and machinery, accidents are very common. It’s the duty of the site management to reduce the accidents in their numbers and criticality. This can be achieved by being aware and taking precautions against accidents. The static illustrate 1/3 of accidents are due to human negligent.

1.      Before workers are working on the scaffolding it must be checked firmly fixed. Extra that guardrail must be fixed across the scaffolding 1m above the platform it can be prevented workers, who are working on the scaffolding, falling down. The board should be fixed for every scaffolding. It prevents down of hand tools, bricks, etc.

2.      Workers who are working lower floors should wear helmet. Workers who are working on higher dangerous places should wear safety belt & helmet.

3.      Operator like jackhammer, breaker, should wear eyes, nose, ear guard

4.      When workers are using electrical instrument it should be in correct condition, prevent of loose connection & there should be trip switch for the whole system.

5.      Goggles & screens must be used when doing the work that might cause to the eyes.

 

   SAFETY OF MACHINERIE

1.      Any machine operator should be well known about operating system of the machine & also before start the machine checked fuel, oil, water etc.

2.      Every machine should be calibrated according to their manual

3.      Machineries are maintained well, once a person who is expert for relevant machine should check. The checking time depend upon the type of machine. It may be a once a time per day or once a time per month.

4.      After used the electrical instrument disconnect the supply.

5.      Power tools are not exposed to rain. They were not use in damp or wet locations. Machineries were not used if there is risk to cause fire or explosion.

 

 SAFETY OF OUTSIDE PEOPLE & PROPERTIES

2.      Construction is not harmful for the averment. If there is blasting in the site it should be covered well.

 

COMMON TYPES OF ACCIDENT

The most common types of accidents at sites are,

Ø  Getting hit by a falling object

Ø  Falling from heights

Ø  Electric shock

Ø  Getting hit by a moving vehicle

Ø  Injury due to moving machinery (ex. Power saw, drill etc.)

     SAFETY EQUIPMENTS

HEAD PROTECTION

Helmet is used to prevent damaging head due to falling objects, overhead loads and sharp projections.

 

          

9.7.2         FOOT PROTECTION

 Proper foot ware is used to protect the foot from falling materials and also to prevent penetration of nails. Ex: - safety shoes and boots.

 

9.7.3         HAND PROTECTION

Protective gloves were given to the workers whenever there is a danger of injuries to hands. Ex: - for bar benders and masons gloves were given

10.7.3   EYE PROTECTION          

Goggles were given to the workers who

engaged breaking, cutting, drilling and welding to protect their eyes.

 

10.7.4   SAFETY BELTS

Safety belts were normally given to the riggers who work in higher elevations to prevent falling down. The belts should be properly checked at the beginning of the day and it should be connected to a proper support. In addition to these protective equipment labors were well instructed and trained to use the safety methods while their working and also notice boards were placed at the critical places. There was a separate officer to look after the safety of the people and site and major safety rallies were carried out to educate the labors about good and bad practices of working and also in handling equipment. I was able to attend to a safety rally as well.
