hazard is any source of potential damage, harm or adverse health
effects on something or someone under certain conditions at
work.
Basically, a hazard can cause harm or adverse effects (to
individuals as health effects or to organizations as property or
equipment losses).
Sometimes a hazard is referred to as being the actual harm or
the health effect it caused rather than the hazard. For example,
the disease tuberculosis (TB) might be called a hazard by some but
in general the TB-causing bacteria would be considered the "hazard"
or "hazardous biological agent".2Fall from heightsWorkers who build
or install roof trusses.Cause fractures, sprains, strains,
contusions, severe damage to internal organs and even death.Control

Arrest SystemsFALL HAZARD STATISTICEach year workers die from
falls. During the year 2007: Total deaths from falls: 835 Deaths in
construction: 442 More than 50% of deaths from falls are in
construction Approximately 15% of all occupational deaths are
fallsNoiseDue to build or install roof trusses, wall and ceiling.A
worker who is repeatedly exposed to noise at 85 decibels or above
without hearing protection is at risk for serious hearing
loss.Control measure :Noise Control StrategiesHearing Conservation
ProgramUsing Hearing ProtectorsSkin contact with Portland cementDue
to concreting activityPortland cement contains hexavalent chromium
which causes allergic dermatitis. Prolonged contact with wet cement
also causes skin irritation and burns.Control measure :Protecting

StationLifting & CarryingDue to formwork and concreting
activity, wall installing, brick laying.Effect - Low back pain
(LBP), Work-related lifting and forceful movements, Whole body
vibration, Awkward postures (bending and twisting), Heavy physical
workControl measure - Determining maximum acceptable weight limits
for lifting and carrying tasks along with suggested solutions for
minimizing the risk of injury from lifting or carrying.Low back
pain (LBP) is among the most common health complaint in
working-aged populations worldwide. In the U.S., 70%-80% of adults
will experience a significant episode of LBP at least once in their
lives. Episodes of LBP are characterized by varying levels of pain
and symptoms in the low back (lumbar spine). Low back disorders can
even cause leg pain or numbness at times.

Anti-Vibration Gloves, Reduced Vibration Power ToolsCrane swing
radiusMaterial mechanically lifted , they have potential to swing
and strike workers.As the load is lifted , the material may swing,
twist or run and catch workers and hit them.Windy condition is the
special hazard in this situation.Control measure Ensure the plants
were supervise and still in good condition.When materials are
mechanically lifted, they have thepotential to swing and strike
workers. As the load islifted, the materials may swing, twist or
turn. Thismovement can catch workers by surprise and theycould be
hit by the swinging load. Windy conditionsare especially hazardous
because the load will swingmore. Depending on where the worker is
standing andthe force behind the load, the worker may fall
toanother level after being struck and sustain evengreater
injuries. In addition to swinging, loads can slipfrom their
riggings and strike workers. Loads must berigged properly to
prevent slippage. 9Ladder workUsed ladder 10 m above ground is
usually beyond the safe reach of ladders.Lengthy ladders are
dangerous to handle.Ladders are useful for carrying out
short-duration, light-weight work within safe reach of the ladder
There are limitations on the sort of work that can be done safely
from ladders. Work more than 10 m above ground is usually beyond
the safe reach of laddersLadders are useful for carrying out
short-duration, light-weight work within safe reach of the ladder;
typically, inspection and repair and painting of small areas of the
buildings surface. Ladders also provide access in scaffolds, in
excavations and in structures where more permanent access has not
yet been provided.10
Only use equipment that is designed for liftingpersonnel.Thank
