LI: WWBAT understand safety
concepts in the workshop

2. © 2012 Delmar, Cengage Learning
Objectives
• Use shop tools and equipment safely
• Understand safety rules

3. © 2012 Delmar, Cengage Learning
Introduction
• Number one priority of any workshop is the
health and safety of its occupants.
– The teacher is responsible for safety training and
for providing a safe working environment
– The student is responsible for his/her/they own
safety and the safety of others
– Accidents often the result of carelessness, lack
of experience, and taking shortcuts
• Injured persons should not be left unattended
– Notify the teacher immediately.

General Personal Safety
• Important points
– Wear safety goggles or a face shield to protect
eyes
– Follow safe lifting procedures
– Wear ear protection when loud tools are used
– Keep long hair tied or under a cap
– Tuck in shirt tails or wear shop clothing
– Leather shoes with a reinforced toe protect better
– Use correct gloves when working with chemicals

Fire Safety
• Common sense is important
– If personal safety jeopardized
• Leave the area
• Call for help
– If you can safely remove the fuel to a fire, do so
• Shut off fuel
• Disconnect electrical source

Fire Extinguishers
• Four kinds of fires and four kinds of fire
extinguishers
– Class A fire can be put out with water
– Class B fire contains flammable liquids
– Class C is electrical
– Class D is a flammable metal (e.g., magnesium)
• Carbon dioxide or dry chemical extinguishers
can be used on Class B and C fires

8. © 2012 Delmar, Cengage Learning
Flammable Materials
• Oil-soaked rags should be stored in covered
metal containers
• They must be disposed using a licensed waste
remover.

9. © 2012 Delmar, Cengage Learning
Fuel Fires
• Fuel/petrol is a major cause of automotive fires.
– Vapors collect in low places and ignite
• Incandescent lights are also a fire hazard
– Florescent bulb enclosed in a plastic tube is
recommended
– Ordinary flashlights also acceptable
• Fuel safety
– Never use fuel to clean parts
– Do not smoke in the workshop
– Do not siphon fuel with your mouth

10. © 2012 Delmar, Cengage Learning
Electrical Fires
• Disconnect the
battery before
working on the
electrical system
– Unbolt the
ground cable
– Ground cable
is bolted to the
engine block

Shop Habits
• Precautions
– Greasy tools and hands should be cleaned
– Spills should be cleaned when they happen
– Oil and solvent spills can be cleaned with rags or
towels
– Waste disposal companies offer a service to
soak up spills with superabsorbent cloths
– Newer products have microbes that “eat” oil or
fuel and convert it to CO2 and water

Shop Habits (cont'd.)

13. © 2012 Delmar, Cengage Learning
Electrical Safety Precautions
• Twelve-volt DC systems don’t cause serious
shock
– Shop equipment powered by 240V alternating
current can be very dangerous
• Do not stand in water when using electric tools
• Turn off tools before plugging in
– Wall outlets should be properly grounded
• Three-wire/pin electrical tools are preferable

14. © 2012 Delmar, Cengage Learning
Cooling Fan Safety
• The fan that draws cool air across the radiator
can be driven by either a belt or electricity
– Fans controlled by electric switch can start
unexpectedly
• Precautions
– Disconnect electric cooling fans before working
near them
– Visually inspect fan blades for damage
• Unbalanced blades may fly apart
– Keep hair and clothing away from fans and fan
drive belts

Coolant Burns
• Most burns are
caused by coolant
or exhaust
systems
• Coolant level is
acceptable if hose
is hard
• If hose collapses,
steam may still
burn

General Hand Tool Safety
• Using hand tools properly prevents cuts
• Precautions
– Inspect tools before use
– Maintain tools in safe working condition
– Do not use worn or broken tools

Vise and Puller Safety
• Vise safety
– Do not over-tighten vise when in wide-open
position
– Never use a piece of pipe on the vise handle
• Puller safety
– Wear eye protection
– Align the puller perpendicular to the part
– Do not use a puller with damaged or worn parts
– Use the correct size puller
– A 3-jaw puller is preferable

– Do not turn on the impact wrench unless the
socket is installed on a nut or bolt
– When the wrench fails to loosen a fastener use a
large breaker bar

General Lifting Safety
• Be sure the lift
contacts the
frame at the
recommended lift
point
• When lifting on a
frame-contact
hoist, raise the
vehicle 15cm
and shake it

24. © 2012 Delmar, Cengage Learning
Lift
Used to raise a
vehicle—useful
when working under
the car

25. © 2012 Delmar, Cengage Learning
Lift Safety Rules

permission before using the lift
• Center the vehicle on the lift, using the lifting
points
• Check ceiling clearance before raising

26. © 2012 Delmar, Cengage Learning
Lifting Points
Recommended lifting points for a
specific vehicle

27. © 2012 Delmar, Cengage Learning
Safety Catch
Make sure the lift’s safety catch is engaged
before working under the vehicle

Alignment Rack
Specialized stall used when working on steering
and suspension systems

29. © 2012 Delmar, Cengage Learning
Alignment Rack
• When using a rack, the car should be pulled
on the rack slowly and carefully
• Someone should guide the driver and help
keep the tires centered on the rack
• Obtain a full demonstration before using the
alignment rack

Hydraulic Floor Jack
(Service Jack) Safety
• Cars have fallen and crushed people who use
jacks that failed
– Hydraulic service jack should be used to raise
and lower a vehicle only
– Use vehicle support stands in pairs
– Position support stands in recommended
locations on the frame
– Use support stands only on a level, concrete
surface

Shop Crane (Engine Hoist)
Safety
• The shop crane can tip over easily when
removing an engine from a car
• Precautions

– Be sure bolts are not too short
– Firmly tighten bolts attaching lifting fixture to part
– Lower the engine as soon as possible before
attempting to roll the crane to a different location
– Be careful when raising the vehicle in the air
while on a frame-contact lift

32. © 2012 Delmar, Cengage Learning

33. © 2012 Delmar, Cengage Learning
Transmission Jack Safety
• Used when vehicle is raised in the air on a lift
– Safest use is when the vehicle is on a wheel-
contact lift
– When a vehicle is on a frame-contact lift, raising
the transmission can result in the vehicle being
lifted off the adapters on the lift
• If its balance is upset, the vehicle could be
knocked off of the lift

– Follow proper procedures and wear eye
protection
• Battery acid contains sulfuric acid and water
– If battery acid gets on your skin immediately
wash with water for at least 15 minutes
– Baking soda neutralizes battery acid
• Hybrid vehicles require special knowledge
– Know what is safe to touch

36. © 2012 Delmar, Cengage Learning
Refrigerant Safety
• Refrigerant is used in air-conditioning systems
– When pressure removed, it boils and vaporizes
• Precautions
– Wear gloves
– Wear goggles
• Refrigerant can cause instant blindness

37. © 2012 Delmar, Cengage Learning
General Safety Around
Automobiles
