•Venus
•Here you could
describe
Theoretically, safety would mean the absence
of danger at work which is made possible by
eliminating hazards that create the danger.

High rate means low safety
and vice versa.

66. CONCLUSIONS

67. A safe working environment
can be very easily achieved
by the proper knowledge and
interaction of the contractor,
designer and the laborers.
Safety is very important in the
construction industry but the safety
scenario in the construction industry,
especially in Bangladesh is very poor,
which results in lot’s of casualties
which hampers the normal working of
the project.
