The Definition of Safety

The condition or state of being free of
accidents.
Why do we need Safety Colors?
Alert people to dangers or hazards
 Help to locate objects
 Make the shop a pleasant place to work
 Promote cleanliness and order
 Help people to react quickly to
emergencies

Safety Colors

RED= Danger
 This
is an area of high
danger or emergency.
 Usually found around
safety switches and
fire equipment.

ORANGE= Warning
 Orange
is used to
designate machine
hazards such as
edges or openings.
 Also used as a
background for
electrical switches,
levers, and controls.
Safety Colors

YELLOW= Caution
 Just
like with traffic
lights it means caution.
 It is mostly used to
identify parts of
machines, such as
wheels, levers, and
knobs that are used to
adjust the machine.

BLUE= Information
 Blue
is used on signs
if a warning or caution
is intended.
 Typically carry the
message “OUT OF
ORDER” or “DO NOT
OPPERATE”
Shop Colors

GREEN= Safety
 Safety
green is a
special shade of green
and indicates the
presence of safety
equipment, safety
areas, first aid, and
medical care.

Black and Yellow
Diagonal Stripes=
Radioactivity
 This
is a marking of
radiation hazards.
Safety Colors
White= It is used to mark of f traffic areas.
Some times white arrows are used to
indicate the direction of traffic.
 White and Black Stripes= Commonly used
as traffic markings.
 Gray= Is used on floors of work areas in
the shop.

Focal Colors
Ivory- Is used to highlight or improve
visibility of certain items.
 Vista Green- It is used to paint bodies of
machines, cabinets, and stationary tool
such as vises.
 Aluminum- Is commonly used on waste
containers such as those for scrap wood,
scrap metal, and rags.

Protective Clothing and Devices

Most work situations in agricultural
mechanics require some type of body
protection.
Safety Glasses and Face Shields
The face and eyes are regarded as the
most critical parts of the body to be
protected.
 Flying objects striking the head can easily
cause blindness or result in death.
 Safety Glasses are a must in the shop.

Common types of Safety Glasses
Hair Restraints
Serious injuries can occur if long hair
becomes in tangled in a drill press, saws,
or other turning equipment.
 Hair can be restrained in several ways:

 A woolen
hat
 A head band
 A hardhat
 A hairnet
Protective Clothing
Clothing must fit properly in order to
reduce or prevent injuries.
 There should be no cuffs, strings, or ties
for turning machinery to catch.
 Clothing should be fire resistant and
provide protection for scrapes and
abrasions.

Protective Clothing Examples
Protective Clothing

Coveralls
 They
are the most versatile and all around
item in the shop due to the fact that they cover
or protect arms, body, and legs.
Footwear
Leather shoes are recommended when
working in the shop and when using
machinery.
 Leather is preferred because of its
strength, durability and comfort.

Gloves

Gloves are needed to keep the hands
warm as well as to protect them from
excessive abrasion, heat, liquids, or
chemicals.
Protective Clothing in the Shop




Safety glasses
A long sleeve heavy
cotton shirt.
Blue jeans or
coveralls to cover
your legs.
Leather boots
Ear Protection

Earmuffs or plugs are recommended when
intensity, frequency, or duration of noise
reaches certain levels.
 Noise
intensity- energy in sound waves
 Noise duration- the length of time a person is
exposed to a sound.
 Decibel- (dB) the standard unit of sound
Common Decibel Levels

The Fire Triangle
To produce a fire, three components must
be present at the same time.
 The three components are: fuel, heat, and
oxygen.
Fuel

Fire
Heat
Oxygen
The Fire Triangle

Fuel is any combustible material that will
burn.
 Combustion
means to burn.
Heat simply refers to the type of energy
that causes the temperature to rise.
 Oxygen is a gas in the atmosphere.

What do we need to do to prevent
fires in the shop?





Store fuels in approved containers
Store fuels away from other materials that may
easily burn.
Store materials in areas that are cooler than
their combustion temperature.
Use fire in only safe surroundings.
Put out fire by removing one or more elements
of the fire triangle.
Classes of Fires

Class A= Ordinary
Combustibles
 Includes
wood, paper
and trash.
 Do not include any
item in the presence of
electricity or any type
of liquid.

Class B= Flammable
Liquids
 Includes
fuels,
greases, paints, and
other liquids, as long
as not in the presence
of electricity.
Types of Fire Contd.

Class C= Electrical
Equipment
 Any
fire in the
presence of electricity.

Class D=
Combustible Metals
 Metals
that will burn.
 Can only be put out by
Class D extinguishers.
Types of Fire Extinguishers

Water with pump or gas pressure
 Class A fires.

Carbon dioxide gas (CO2)
 Class

B and C fires.
Dry chemical
 Class A,

B, and C fires
Blanket
 Used
for smothering fires on humans or animals.
Fire Extinguishers are marked according to
the class they will safely work. Extinguishers
are marked with standardized symbols so the
reader can react quickly to the emergency.

Using a Fire Extinguisher
1. Hold upright. Pull ring pin.
 2. Start back 10 feet. Aim at base of the

Emergencies and accidents.
Notify the teacher.
 Keep everyone calm.
 Follow the direction of the teacher.
 Call the fire department.
 Clear the area.
 Use a fire extinguisher if this seems logical
under the circumstances.
