Shop Safety Awareness and Principles for Safety

Of all farm related accidents, nearly 50% involve working with machinery

Safety involves developing an environment free from danger, risk, or injury

Number one key to shop safety is the people who use the shop Those who work in a shop should always:

Be trained in safe and proper tool operations Pass a safety test prior to using the shop

Shop Safety Awareness and Principles for Safety

Keep the shop in an orderly manner to prevent tripping and related injuries

Remove unnecessary hazards such as oily rags

Minimize danger by making sure all machines have safety shields in place prior to and during operation

Shop Safety Awareness and Principles for Safety

Wear appropriate personal protective clothing and devices:

Safety glasses or goggles should always be worn to prevent eye injury from dust and flying objects

Leather steel-toed shoes offer protection from items dropped or falling on the feet

Ear protection (plugs or muffs) can prevent hearing loss when the noise level exceeds 90 dB (decibels)

Other safety clothing may be required for certain work such as welding

Safety Color Coding in the Agricultural Mechanics Shop Development of Safety Color Coding

National organizations worked together to develop the system

The American Society of Agricultural Engineers and the Safety Committee of the American Vocational Association published the code

Color coding alerts people to dangers and hazards, provides information to help on reacting quickly in an emergency

Each color or combination of colors conveys a special message based on a standard code

Basic Safety Code Colors

RED Identifies areas of danger Used on safety switches and fire extinguishers Red = Danger

ORANGE Designates machine hazards, such as edges and openings Also used as background for electrical switches, levers and

controls Orange = Warning

Basic Safety Code Colors

YELLOW Identifies wheels, levers, and knobs that adjust or control

machines Yellow = Caution

BLUE Used on signs such as “Out of Order” to identify broken shop

equipment that does not work or does not work properly Blue = Information

GREEN Indicates the presence of first aid and safety equipment Green = Safety

Fire Hazards in the Agricultural Mechanics Shop

The Fire Triangle – components necessary for a fire:

Fuel – any combustible material that will burn Oily rags, sawdust, paper, ect.

Heat – most materials burn if they are made hot enough

Oxygen (O) – gas in the atmosphere that is not a fuel, but must be present for fuels to burn

Fire Hazards in the Agricultural Mechanics Shop

Fire Prevention Take away one of the components of the fire triangle and fire will

not start or will stop if already started What is one thing we can take away from the triangle to prevent a fire?

Safe storage of fuels or combustible materials is the easiest fire

prevention strategy

Store fuels in approved containers

Clean shop facilities also decrease the chance of fire and injury

Extinguishing Fires

Fire Extinguishers Know the kind of fire extinguisher that is used for different kinds

of fires prior to the fire Example: Class A Fire Extinguishers use water to control ordinary

combustibles

Know the placement of fire extinguishers so that time is not taken looking for the extinguisher if a fire occurs Fire Extinguishers should be hung on walls within easy reach in

areas where fires would most likely occur Where is our fire extinguisher in the classroom? Why do you think it is located there?

Know how to use the fire extinguisher

Extinguishing Fires Using a Fire Extinguisher:

Generally, extinguishers are held upright The ring is pulled Lever is pressed Nozzle of the extinguisher is directed toward the base of the fire

to discharge the extinguisher

Other examples of extinguishing fires: Wrapping a person in a blanket whose clothes

are on fire to eliminate oxygen from getting to

the fire Cooling with water from a hose or bucket
