3. Why Safety Instruction?
Develop an awareness of hazards and
become more safety conscious at school,
work or at home.
Develop a serious attitude toward the
use and practice of safety procedures
To prepare for safety before entering the
work area, in the work area, at a
workstation and on leaving the work
area
To recognize safety symbols, color codes
and safety equipment
4. Emphasis on Safety in Society
Federal Government
State Government
Local Governments
Schools
Private Agencies/Businesses/Industry
Manufacturers of tools and machines
5. WHY?
Federal, State and Local
Governments pass laws in
order to protect citizens
(taxpayers)
Schools are responsible to
parents for sending kids
home in the same condition
they arrive each day.
6. WHY?
Private Agencies/Businesses/Industry are
held accountable for providing a safe
working environment for their employees.
1. (Law suits cut into profits.)
2. Company is less productive when
employees are lost or disabled.
3. Keeping experienced employees safe is
more productive and profitable than
constantly training replacements.
7. WHY?
Manufacturers of tools and machines
want to avoid lawsuits or recalls from
defective products. That’s bad P.R.
and will hurt sales. They also want you
to come back and buy their products
again.
11. The Four Categories of Tools
Cutting Tools – A tool or machine that does
it’s job by cutting or removing material.
Shock Tools – Any tool or machine that hits or
is hit by something to complete it’s task.
Torsion Tools – These tools work by twisting.
Material Handling Tools – This group of
tools are used to control material in a variety of
ways: Moving, holding, lifting, pressing, prying
apart, etc.
18. What is a Hazard?
A hazard is a
dangerous
situation that
could cause
an accident.
19. Three Types of Hazards
Immediate Hazard – A situation that is
visible and presents an immediate danger.
Potential Hazard – A situation that is
visible but could become dangerous if
combined with other situations or events.
Hidden Hazard – An existing dangerous
situation that is hidden from obvious view.
38. School Lab Safety
The only law affecting work in school labs is:
Georgia Code 32-4201. This law mandates the wearing
of safety goggles by every student, teacher, and visitor
participating in or observing chemical, physical, or
combined chemical physical activities involving
caustic or explosive materials, hot liquids or solids,
injurious radiation or other hazards.
46. Accidents Take Their Toll
Businesses spend $170 BILLION a year on costs
associated with occupational injuries and illnesses –
expenditures that come straight out of company profits.
In addition Lost productivity from injuries and illnesses
costs companies $60 BILLION each year. – O.S.H.A
Auto/Home owners insurance companies rates are
higher in some places These factors determine the rates
you pay: Where you live (apartments vs. home) or drive
the most, your sex, age group, your accident record etc.
The higher the risk that they’ll have to pay, the higher
your rates will be.

51. Sources of
Ingredient of the Air that
covers the Earth.
Oxygen Tanks (Oxy-
Acetylene Welding) Very
Explosive in its pure state
52. Sources of
Man
Friction
Sparks
Magnified Sunlight
Electrical Defects
Spontaneous Combustion
53. Sources of
A fuel is anything that will burn.
Different elements have different
Flashpoints. (the temperature at
which a fuel starts to burn)
54. Describe how a Match Starts to Burn
Not enough friction to reach the wood’s flashpoint
Not enough friction to reach the red chemical’s flashpoint
Just enough friction to reach the white chemical’s
flashpoint which ignites the red chemical which burns hot
enough to reach the wood’s flashpoint
55. The match continues to burn until one of the
three elements are eliminated
Take away the Oxygen
56. The match continues to burn until one of the
three elements are eliminated
Take away the Heat
57. The match continues to burn until one of the
three elements are eliminated
Take away the Fuel
65. Never Overload Circuits
Wires could get hot enough to melt
the insulation and cause a short
circuit inside the wall.
66. What is a Short Circuit?
Electrons are forced to move through the device when the
circuit is working properly
But Electrons will ALWAYS look for the shortest path back to
where they came from…even if that means jumping (arcing)
between two conductors which could electrocute or start fires.
