How Excavations Carry on Safely in the Workplace:
Excavation and trenching are among the most
hazardous construction operations. The Safety and Health code should follow
strictly during Excavation and Trenching in the workplace. Trenching and
excavation work presents serious hazards to all workers involved. Especially in
trafficked crowded city areas and moreover in the rainy season is more hazardous and much more likely than other excavation-related accidents to result in
worker fatalities. Excavation in soil movement and cave-ins should take special
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 designed 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 aluminum
hydraulic or other types of supports to prevent soil movement and caverns.
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, the water content of the 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 have past long job experience on so many
trenching, shoring, and backfilling, but it is important to approach each new
job with the utmost care and preparation. Most job accidents result
directly from insufficient initial planning. So pre-planning for every
excavation job and taking standard safety measures can reduce accidents.

ØIs their edge protection to stop people or materials from falling?
ØExcavated spoil stored well away from the edge?
ØThe excavation sides 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 a maximum of 9 meters apart?
I really enjoyed reading this post. big fan. Keep up the good work andplease tell me when can you publish more articles or where can I read more on the subject?
