1. Reducing Hazards in Agricultural Mechanics

2. Objectives Reduce hazards in agricultural mechanics
State the three conditions necessary for combustion
Match appropriate types of fire extinguishers to each class of fire
Describe appropriate action in case of fire, accident, or other emergency

3. Introduction
Fire, slow moving veichales, highway crossings and chemicals create a unique hazard in agricultural mechanics
Each hold dangers to the worker and to others in the area
However, there are ways to reduce hazards and take action quickly in accidents occur.

4. Reducing Fire Hazards Most losses from fire can be prevented
It requires attention and knowledge of how fire works

5. The Fire Triangle
To produce fire, three components must be present at the same time
Fuel: any combustible material that will burn
Heat: a type of energy that causes the temperture to rise
Oxygen: gas in the atmosphere. It is not a fuel but must be present for fuels to burn.
Combined they are known as the fire triangle
If any component is missing a fire CAN NOT be started
If any component is removed the fire will go out.

6. The Fire Triangle
heat
fuel
oxygen

7. Preventing Fires in Ag Mechanics
Store fuels in approved containers
Store fuels away from other materials that burn easily
Store materials in areas that are cooler than their combustion temperature
Use fire only in safe surroundings
Put out fires by removing one or more elements in the fire triangle
Fire prevention goes hand in hand with safe use of equipment!

8. Extinguishing Fire

9. Extinguishing Fire Extinguished by Adding water to cool them
Covering them to cut off oxygen
Removing the fuel

10. Classes of Fire Class A- ordinary combustibles
Class B- flammable liquids
Class C- Electrical equipment
Class D- Combustible metals
Classification is based on how safely and cheaply a material is extinguished
Water is generally the cheapest but is not always the safest or most effective.

11. Types of Fire Extinguishers
The proper fire extinguisher can put out a fire within seconds!
However it must happen when the fire first burst into flames
The key is the proper extinguisher used immediately and in the proper way.

12. Common Types of Fire Extinguishers
Water with pump or gas pressure (Class A fires)
Carbon dioxide gas (CO2) (Class B & C)
Dry chemical (A, B, C)
Blanket (used to smother fire on humans or animals)

13. Common Types of Fire ExtinguishersA B
Combustibles
Liquids
Equipment D
Metals

14. Location of Fire Extinguishers
Very important
Should be placed in areas were fire is likely to occur
Should be in clean, dry areas near exits within easy reach
Should not be be more than 3 ½-5’ above the floor
Bottom should be at least 4” above the floor
Everyone should be familiar with the locations and use of all types of extinguishers

15. Using Fire Extinguisher
Step 1: Hold upright, pull ring pin.
Step 2: Start back 10’ aim at base of fire
Step 3: Squeeze lever, sweep side to side.

16. Package Labels
May be a matter of life or death in the event of accident
This products may cause illness, death
It is very important to keep materials in their original containers
Pesticide labels are legal documents
Label directions are required by law to be accurate and complete
Labels should be read again before handling, mixing, using or disposing of pesticides
Pesticide labels have at least sixteen items of information
Pesticides should always be stored in a locked cabinentor area.

18. Summary Fire can not burn with out fuel, oxygen and heat
Fire, slow moving veichles and chemicals all cause a hazard to those in agriculture.
Fire can be extiguished by removing one part of the fire triangle.
Common types of fire extinguishers are water, carbon dioxide gas, dry chemical, and blanket
The placement of fire extinguishers is very important.
Slow moving vehicle emblems are required on all vehicles that travel a maximum speed of 25 mph on public roads
Pesticide are dangerous and can cause injury or death
Pesticide labels MUST be read to ensure proper handling.
