A Safety Attitude
Safety is not often thought about as we
proceed through routine daily tasks. Often we
all expose ourselves to needless risk because
we have gotten away with it and so far no
harmful effects have resulted. However, in a
potentially hazardous job environment, your
career and perhaps even you life may indeed
rest on safe work habits and adopting a safety
attitude not only at work but in everything
that you do.

Safety Equipment
In the machine shop there are many hazards.
However, if you learn to recognize and are
aware of these hazards and take steps to
protect yourself and furthermore adopt a
safety attitude, then you may work in this
environment your entire career and never have
and accident. Part of machine shop safety
practices is knowing what safety equipment is
required and how to use it properly.

Both in your training
and in your career,
EYE PROTECTION will
be the most important
safety consideration,
in the machine shop.

in the shop at all times

Hearing Safety
The working machine shop
environment does not
usually cause an excessive
noise problem. However,
you should be aware that
exposure to excessive
noise in or outside the
shop can have a
permanent detrimental
effect on you hearing. Ear
plugs may be worn if the
noise level is excessive.

Dust and Fume Safety
Dust and fumes should
NEVER be inhaled under any
circumstances. Bench and
pedestal grinders may be
equipped with vacuum dust
collectors to control grinder
dust. You must be aware of
the hazards of breathing
dust and fumes from any
source and take the proper
steps to protect yourself and
control this problem.

but be aware of where
fire extinguishers are
and how to use the
proper types depending
on the type of fire
situation.
