Tools and machines are a major source of injuried. Hand tools cause
approximately 8% of lost-time occupational accidents, machines cause
an even greater share. Because powered and machines involve much greater
energy and power, injuries from them are likely to be more severe then for
hand-operated ones.
HAZARDS
One hazard is being struck by tool, moving machine, or machine part. For
example, most everyone has struck a finger or thumb when learning td drive
a nail with a hammer.Motor vehicle, one type of machine, strick people
everyday.
Another hazard of certain tools and machines is being struck by materials
acted on. When useing a cold chisel or star drill and hammer to break a hole
in concrete, particles of concerete fly from the tip of the tool with each
blow. Particles fly from the cutting tool as a lathe remove material. The
particles may strike the tool or machine user or someone else. Some part of
the body, such as the eyes, have a greater risk of injury than others when
struck by flying materials.
Another kinds of hazard is getting caught in s machine or tool. Many people
have experienced the pinching action of a pair of pliers. One can get caught
in many ways: in power transmission elements, such as belts, chains, gears,
linkages, and other components, and in the portions of the machine that act
on something else.
Repeated motion by users in operating a tool or machine can lead to a group
of injuries called cumulative trauma disorders or repeated mation disorder.
The power source may add to the inherent hazards of a tool or machine itself.
For example, electrical power bring certain hazards. Combustiable fuel,
explosives, hydraulices, and pneumatics each bring an additional hazard to the
tools and machines they power. Matchines and tools may create noise hazards,
produce air contaminants, become hot, or create other hazards.
INJURIES
There are many kinds of injuries related to the tools and machines. Tools and
machines designed to cut materials also will cut people. Knives, hatchets,
and axes are examples of hand tools. Hedge trimmers, paper cutting machines,
and shears are examples of powered tools and matchines.
Abrasion injuries result from contact with machines that friction or abrasion
such as grinding and sanding equipment. Punctures wounds can result from
contact with sharp edges on equipment.
A variety of crushing injuries, fractures, and other injuries can result from
getting caught in the compression action of a tool or machine.
Flying particles may cause injuries to surface tissue on impact. The
likelihood of injury depends on the tissue struck, the strength of the tissue,
and the ability of the tissue to absorb and distribute force. The largre the
material in mation, the greater the chances of injury. Initial impact may not
be the only concern. The materials may have other hazards associated with
them. For example, they may be caustic or they amy berought and cause injury
if they contact skin or other tissue.
Objects may fall from machines and crash hands, feet, or bodies. Materials
being operated on by tools and machines may be poory anchored and subsequently
may fall, producing crushing or related injuries.
