• Immature & unsafe work practices will not be tolerated

ABILITY TO WORK ON VEHICLES WILL BE REMOVED

IF SUCH BEHAVIOUR OCCURS

PROTECTIVE EQUIPMENT

4

Personal Protective Equipment

When must eye protection be worn in the shop?

When using power tools or near someone using them

When underneath a vehicle

5

Two types of eye protection you can use…

safety glasses

face shield

6

Use ear protection…

Air chisel

Impact gun

Die Grinder

7

Hand Protection

Wear approved gloves whenever handling caustic chemicals (a chemical capable of burning, corroding or destroying living tissue)

Wear protective gloves to avoid scratches & cuts

8

Do’s and Don'ts

No open-toed shoes

CSA approved footwear is best

Remove any rings, watches, bracelets or long necklaces before working in the shop

Coveralls or a shop coat must be worn

9

Long hair needs to be tied back!

10

Dangers Under the Hood…

Radiator fans (3 types)…

Electric

Belt driven (clutch type)

Belt driven (direct)

11

Burn Hazards!

The following items can cause burns

to your hands or face…

• Radiator cap

coolant is >100

C

coolant is pressurized

don’t remove it unless it’s cold to the touch!

• Exhaust manifold

exhaust gases are >1000

C

• Catalytic converter

very hot

12

Protecting Your Lungs…

If you are replacing brake friction material or a clutch, wearing a

Particle Mask is recommended

Brake linings & clutch discs may contain asbestos!

WHY?

13

Protecting Your Lungs

Exhaust “donuts” & some cylinder head gaskets contain asbestos!

14

Exhaust Gases

Carbon Monoxide is…

Colorless

Odorless

When running a vehicle in the shop we must use the rubber hoses to vent exhaust gases outside

Carbon Monoxide (CO)

• CO is a by-product of incomplete combustion when a substance is burned

• Why is CO so poisonous?

Human blood contains haemoglobin which attracts & carries oxygen through the body to sustain life.

Haemoglobin though is 200 times more attracted to CO

If CO is taken into the lungs the haemoglobin combines more readily with it rather than the oxygen

The CO then moves through the blood stream starving the body of the oxygen that it needs

* This process is called CO Poisoning

2 deep breaths of air with a 2% concentration of CO may cause unconsciousness & death in a few minutes

16

Fire Hazards

Flammable or combustible items…

fuel

oil/lubricants

cleaning solvent: (use rubber gloves)

WD40, paint etc.

Brake clean

must be stored in a flammable materials cabinet

not like this…

17

Fuel Vapors & Fires

• Anytime the fuel system is disconnected (fuel tank, carburetor, fuel pump, fuel injectors etc.), fuel vapors are present,

prevent fires by…

disconnecting the negative battery terminal

• keep sparks away from the fuel vapors

• watch those working around you

• have a fire extinguisher nearby

• Hang fuel soaked rags outside

to air dry

Gasoline is not a recommended

cleaning solvent

18

Other Fire Hazards…

• Oily, or greasy items must be placed in the fire-proof rag container when you are finished using them!

WHY?

Oily rags are

CUMBUSTIBLE

19

Tripping & Slipping Hazards

• sweep the shop floor as you work & at the end of the class!

• floor dry is to be used for large oil spills only

• keep shop floor free of tripping hazards

storage of parts?

A CLEAN SHOP IS A SAFE SHOP!

20

Compressed Air

• do not use compressed air to clean off clothes & skin

at 4”, 40 PSI can rupture an eardrum, cause a brain hemorrhage or death

12psi can pop an eyeball from its socket

4psi in the mouth can rupture a lung or intestine

compressed air entering a small wound on the hand has been known to inflate the arm to the size of a grapefruit

air entering the belly button through a layer of clothing can rupture the intestines

Do not use an Oxygen

bottle to blow off clothes

this could ignite fuel or

oil on your clothes

Never look into the “business” end!

Never point it towards your body!

Parking Vehicles in Automotive Shops

Air Guns & Sockets

25

Battery Safety

• Batteries contain a liquid called

electrolyte which contains sulphuric acid

• You must be careful not to splash the electrolyte in your eyes or get it on your skin!

• Batteries give off hydrogen gas thru vents in the top of the battery

• Keep sparks & flames away from the battery!!!

26

27

Use gloves when servicing batteries…

29

b) always reinstall positive first, then negative

• remember: NPPN

• ensure the terminals cannot be moved by hand

• coat the terminals with spray paint or terminal protector to

reduce further corrosion

Connecting a Battery Charger

1. Service (Clean) the battery.

2. Connect the battery charger cables (charger off and unplugged).

(red to positive, black to negative)
