SAFETY
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.

& 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

Machineries were not used if there is risk to cause fire or explosion.
SAFETY
OF OUTSIDE PEOPLE & PROPERTIES

is high rise building upper floors covered with safety net. Should be informed
to outside people workers are working in upper floors with the use of mentioned
in board.
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

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.

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.
