How Excavations Carry on Safely in Workplace:   

Safety for Excavation work

Excavation and trenching are among the most hazardous construction operations. The Safety and Health code should follow strictly during Excavation and Trenching in work place. Trenching and excavation work presents serious hazards to all workers involved. Especially in trafficked crowded city area and moreover in rainy season is more hazardous and are much more likely than other excavation-related accidents to result in worker fatalities. Excavation in soil movement and cave-ins should take especial care. Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment.

Nobody should enter an unprotected trench! Trenches about 1.5 meters deep or greater require a protective system unless the excavation is made entirely in stable rock. Trenches about 6.meters deep or greater require that the protective system be de-signed by a registered professional engineer or be based on tabulated data prepared and or approved by a registered professional engineer.

There are different types of protective systems are available. Sloping involves cutting back the trench wall at an angle inclined away from the excavation. Shoring requires installing aluminium hydraulic or other types of supports to prevent soil movement and caveins. Shielding protects workers by using trench boxes or other types of supports to prevent soil cave-ins. Designing a protective system can be complex because you must consider many factors: soil classification, depth of cut, water content of soil, changes due to weather or climate, surcharge loads (eg., spoil, other materials to be used in the trench) and other operations in the vicinity.

You may be have past long job experienced on so many trenching, shoring, and backfilling, but it is important to approach each new job with the utmost care and preparation. Most of the job accidents result directly from insufficient initial planning. So pre planning for every excavation job and take standard safety measure can reduce accident.

If working in or near EXCAVATIONS, Please check:

ØIs there edge protection to stop people or materials falling?

ØExcavated spoil is stored well away from the edge?

ØThe excavation sides are stable before entering?

ØThe integrity of any shoring in place before entering?

ØNo site traffic travel near the edge of excavations?

ØThere is at least two ladders and maximum 9 meters apart?
