General Shop Safety
Please read over this Section carefully.
- If you have any questions about the operation of any machine
or tool ask your instructor.
- Following a few basic safety procedures will assure a
hazard-free experience for you and others working in the lab. Ask
your instructor or open lab facilitator to assist you in starting
up equipment and in fabrication and modifications of existing
equipment. Practice common sense. If your not comfortable with
the machine set up, don’t do it. Most lab accidents are a
result of lack of knowledge, not carelessness. If you have any
doubt, ask your instructor or lab assistant.
- Regular hours: Access to the student lab is available during
scheduled lab hours only.
- Under no circumstances may work be done in the lab by one
- Students wishing to use the lab after hours must have a
qualified person in the lab.
- No more than 2 machine tools may be in use at any time.
- The lab is not available on weekends.
Clothing & Safe
- Students will wear clothing appropriate to their work
assignments. Clothing will be in reasonably good condition and
- For those working with machinery or in other hazardous
operations, clothing should be well fitted, with no loose or
flowing appendages. Sleeves, if full length, should be buttoned
at the wrist. The practice of working without a shirt is not
approved. Loose fitting clothing must be tucked in or tied up.
Neckties must be removed.
- Students with long hair who work around moving machinery must
wear adequate hair covering to preclude the possibility of
entanglement. Long hair must be tied back at all times.
- Jewelry such as rings, pendants, necklaces, earrings, watches
shall not be worn when they constitute a hazard, i.e. working
around moving machinery, electrical or electronics equipment,
etc. Bracelets and other loose jewelry must be removed prior to
using the lab.
- Unless working conditions dictate otherwise, students must
wear shoes while at work. Shoes should be well-fitted with good
soles and heels and of a style that completely covers the foot.
Open-toe shoes or light-weight shoes of the canvas "sneaker" type
may not be safe. No sandals or opened toed shoes are permitted in
the work area. If lifting heavy objects you are required to wear
steel toe safety shoes Safety shoes are recommended in
- All students who operate a machine tool must either
have taken a introductory course of study or, through their prior
experience, be able to prove their proficiency to the lab
- The first step in preventing personal injury or machine
damage in the lab is to make sure that you are familiar with and
know how to operate correctly the equipment you will be using. If
you don't know ask the instructor or other lab personnel.
- How do accidents happen? Accidents are caused by inattention,
taking chances, horseplay, bad judgment, fatigue,
uncooperativeness, improper clothing, defective tools, etc.
- How do we help to avoid accidents? By strictly following the
safety rules given in the following pages and by cooperating
with, and following any additional instructions, the lab
instructor might have.
- Safety Glasses: Safety glasses must be worn at all times in
the lab when using machine tools (mill, lathe, drill etc.) and
when using manual tools made of high tensile steel such as taps.
High tensile steel can shatter and send chips flying.
- Clothing: Rotating spindles can catch clothes, hair, gloves
and jewelry. When using machines with rotating spindles, wear a
short sleeve shirt or roll your sleeves past your elbow, pull
back long hair (but do not braid), and remove jewelry (especially
rings, watches, necklaces, and bracelets) and anything else that
could get caught in the spindle. DO NOT wear gloves. Sandals are
not allowed in the lab.
- Hearing Protection: Use ear protection if you are using a
loud machine. Foam ear [INVALID]s are available by request.
- Buddy system: Never machine alone. There must always be
someone nearby in case you get hurt.
- Limit student access to tools and equipment. Students using
machining tools and equipment beyond established working hours
and during weekends shall be prohibited.
- Provide eye protection to authorized machine tool users and
visitors upon entry into a machine shop.
- Report any job-related injuries or illnesses, questions on
health and safety, or any unsafe or unhealthy working conditions
to your instructor.
Training / Operations:
Do not operate a machine until you have been trained to use
it properly. Other qualified users can give training.
Use appropriate speeds and feeds. Consult the Machinery's
Handbook or other appropriate machining guideline.
Do not disturb someone while they are using a machine. Wait
until they have finished machining. Machining is very dangerous
and requires concentration. If you interrupt somebody they could
make a mistake that leads to an accident.
The main fluorescent lights in the machine shop run off the
110 V, 60 Hz electrical supply and effectively strobe at 60 or
120 Hz. Machines that rotate at harmonics of 60 Hz will appear to
be stationary. Do not reach for a spindle that looks stationary
but is rotating.
Cutting fluid must be used during all cutting, machining,
turning, tapping, and drilling operations to promote proper chip
removal and prolong tool life.
Precision instruments (micrometers, rulers, etc.) should
never come into contact with each other or with any surface of
equal or greater hardness. i.e. Never put a micrometer on a metal
surface. Precision instruments are ground very carefully. Any
scratches on their surface make them less accurate and can make
Operate only the specific machines, tools and equipment they
have been trained to use.
Report defective machinery, equipment and hazardous
conditions to the lab technician.
Do not remove guards from machinery and equipment except when
necessary for servicing.
Tool and machine damage must be reported to the
Individuals will be classified as "Authorized Users" upon
completion of training.
- Clean up! When you finish using a machine, clean the machine
thoroughly. Sweep the floor and adjacent workbench surfaces.
Coolant should be wiped off and all the chips cleared. If
appropriate, lubricate the machine. Leaving machines dirty is
inconsiderate and is bad for the machines. Coolant and chips can
get into the moving parts of the machine and cause rust and wear.
Refusal to participate in proper clean-up procedures will be a
direct lose of lab use and privileges to those individual.
- Do not use high-pressure air to clean machines. High-pressure
air can push chips into the moving parts of the machinery and
cause excessive wear.
- Tools must be put away under the MFGT/MFGE system. You are
not the only user of the facility. You will waste other people's
time if you don't put tools away in the correct place. Return all
tools, fasteners, and materials to their proper location when you
finish work or at the end of the day. Do no leave tools out
- If you are last to leave, check that everything is order. If
necessary, sweep the floor and put away anything left out.
- Food is allowed only in designated areas in the shop. Drinks
must be in containers with non-spill lids.
- Tobacco Products are Strictly Prohibited. Smoking and
non-smoking tobacco use is not permitted. (Tobacco chew, Spit
bottles, cigarettes, cigars, and all tobacco paraphernalia are
