Agricultural Hazards
Set 3
Marissa Morton SAAIP Top Jobs Intern
2
Mechanical Hazards
  • Pinch PointHazard that is formed when two
    machine parts move together and at least one of
    the parts moves in a circle
  • Wrap PointAny type of rotating machine component
  • Shear Pointwhen the edges of two machine parts
    move across or close enough to each other to cut
    a relatively soft material

3
Mechanical Hazards
  • Crush Pointsformed when two objects are moving
    toward each other, or when one object is moving
    toward a stationary object, and the gap between
    the two is decreasing
  • Pull-In Pointsparts that come close with each
    other, such as feed rolls, often form pull-in
    points.
  • Burn PointsHot mufflers, engine blocks, pipes,
    and fluids (fuel, oils, chemicals)

4
Mechanical Hazards
  • Freewheeling Partsparts of a machine continue
    moving after the power to the machine is turned
    off.
  • Stored Energyenergy that is confined is released
    unexpectedly.
  • Thrown Objectoccurs as normal machine operations
    discharge materials into the surrounding
    environment.

5
Noise Hazards
  • Noise is measured in decibels.
  • Examples
  • 15 Decibels A Whisper
  • 50 Decibels Gentle Breeze
  • 60 Decibels Normal Talk Level
  • 90 Decibels Chopping Silage
  • 100 Decibels Tractor at work
  • 140 Decibels Shotgun Blast or Jet Engine
  • Sound loss starts occurring at about 85 Decibels

6
Respiratory Hazards
  • Dustssolid particles (0.1-25 microns in size)
    created by handling, crushing, grinding, and
    moving materials such as rock, metal, wood, and
    crops.
  • MistsLiquid droplets suspended in the air
    represent mists as a respiration hazard (example
    paint sprays and cutting oil).
  • FumesMaterial that becomes airborne during
    welding (metal welding rod and flux) are examples
    of fumes.

7
Gases and Vapors
  • Common gases and vapors include those from
  • Manure Gases
  • Farm Shop Gases
  • Silo Gases
  • Welding Vapors
  • Engine Vapors
  • Solvents and Paint Thinners

8
Lung Disease and Asthma
  • Farmers LungAllergic reaction caused by
    inhaling moldy hay, straw, and grain.
  • Organic Dust Toxicity Syndrome (ODTS)caused by a
    reaction to inhaling molds from spoiling grain
    and forage.
  • AsthmaDisease of the respiratory system. The
    small air tubes in the lungs tend to swell and
    air tubes tighten when an asthma attack occurs.

9
Working With Livestock
  • Youth under age 16 are prohibited from working in
    a yard, pen, or stall with
  • Cows with newborn calves
  • Bulls, boars, or stud horses kept for breeding
    purposes
  • Sows with nursing pigs
  • Be aware of Flight Zones
  • Flight zones are animals personal space. An
    excited animal has a larger flight zone.

10
Working with Livestock
  • Precautions to Take
  • Plan an escape route
  • Wear steel-toed shoes
  • Avoid animals hind legs
  • Use squeeze clutches to hold animals
  • Approach livestock so that animals can see you
    coming
  • Move cattle in well lit places
  • Avoid loud noises and quick movements
  • Be patient
  • Keep animal handling facilities clear of sharp
    objects
  • Ask for help when moving animals if the animal is
    excited or nervous
  • If the animal is nervous, wait 30 minutes before
    moving the animal

11
Point of Balance
  • An animals point of balance is the shoulder
  • If you stand behind the shoulder, the animal will
    move forward.
  • When you stand in front of the shoulder, the
    animal will stop moving forward

12
Agricultural Pesticides
  • There are four ways that chemical exposure can
    occur
  • Oral (mouth)
  • Dermal (skin)
  • Inhalation (lungs)
  • Ocular (eyes)

13
Electrical Hazards
  • Two types of hazards
  • Electric Shock Hazard
  • Heat and Fire Hazard
  • Electrical Devices Used
  • Distribution Panel
  • Underwriters Laboratories
  • Switches and Receptacles

14
Electrical Hazards
  • Circuit Breakers and Fuses
  • Grounding
  • Lock-Outs
  • Hostile Farm Conditions
  • Extension Cords
  • Underground Utilities

15
Key Terms in Fire Safety
  • Auto-Ignition
  • Combustible
  • Flammable/Nonflammable
  • Flash Point
  • Kindling Point/Ignition Point
  • Spontaneous Combustion
  • Vapors
  • Volatility

16
The Fire Triangle
  • There are three things necessary to start a fire
  • Fuel
  • Heat
  • Air

17
Fire Prevention and Control
  • Work-Site Analysis
  • Maintenance and Housekeeping
  • Fire Prevention and Control Training

18
Using a Fire Extinguisher
  • 4 Step process called PASS
  • Pull the Pin
  • Aim at the base of the fire
  • Squeeze the trigger
  • Sweep from side to side

Preventing Hay Fires
  • Harvest Practicesmow in early morning
  • Conditioning Practicesless than 50 humidity
  • Bailing Practices18-20 moisture
  • Storage Practicesstore hay under cover

20
What is a Confined Space?
  • OSHA defines confined spaces as
  • Space large enough and so configured that a
    person can enter and perform assigned work.
  • Space limited in openings for entry and exit
    purposes
  • Space lacking natural ventilation
  • Space that could contain or produce dangerous
    contaminants
  • Space not intended for continuous human occupancy

Youth under age 16 PROHIBITED from working in a
confined space!
21
Silo Safety Guidelines
  • Stay out of newly filled silos for at least 2
    weeksuse breathing apparatus if you must enter
  • Close feed room door to barn
  • If silo must be entered
  • Run Ventilation fan
  • Get help from an adult
  • Wear dust mask

22
Plugged EquipmentSafety Tips
  • Disengage power to the machine
  • Turn off tractor engine
  • Wait for free-wheeling blower fan blades to come
    to a complete stop
  • DO NOT use your hands and feet to unplug a
    machine!

Manure Storage
  • Hazardous Manure Gases
  • Hydrogen Sulfide
  • Ammonia
  • Carbon Dioxide
  • Methane

Manure Gases Can Kill!
25
Manure Storage Precautions
  • Keep people and animals out of confinement
    buildings during manure storage agitation and
    pumping
  • Ventilate the area for several hours
  • Allow one to two feet of air space above manure
    surface for gases
  • Prohibit smoking and other ignition sources
  • Keep manure agitators below liquid manures
    surface
  • Remove temporary access ladders
  • Lock access to permanent ladders
  • Do not drive on crusted manure surfaces
  • Warn visitors and guests of hazards
  • Post signs at manure storage areas

26
Anhydrous Ammonia
  • System Components Include
  • Nurse/Delivery Tank
  • Control Valves (for withdrawal, fill, pressure
    relief, and return lines)
  • Pressure Gauges
  • Transfer Hoses
  • Applicator Tank (for field application)

Anhydrous Ammonia can result in permanent damage
to your lungs!
27
Chemical Safety Points
  • Read product labels to understand the safety
    requirements of the product
  • Do not mix chemical solutions without adult
    supervision
  • Use proper personal protective equipment to
    protect eyes, skin, and lungs.

28
Animal Hazards
  • Zoonosesterm that denotes diseases that can be
    transmitted between vertebrate animals and
    humans. There are several ways in which it can
    be transmitted
  • Direct Animal Contact animal manure, urine,
    bedding, and products such as raw meat,
    unprocessed milk, hides, hair, etc.
  • Indirect Animal Contact soil, plants, and water
    (surface and well water) may be contaminated by
    animal waste

29
Stinging/Biting Insects
  • Wasps, hornets, bees, spiders, tarantulas, and
    other stinging and biting insects are found
    throughout America
  • Two types of insect bite reactions
  • Allergic Reaction
  • Anaphylactic Shock (caused by insect venom and is
    a serious medical emergency)

30
Poisonous Snakes
  • Poisonous snakes typically have angular heads and
    a pit in front of the eyes. Take the following
    precautions if such a snake is encountered
  • Slowly back away
  • Make no sudden moves
  • Report incident to those that may need to work in
    the same area
  • If a bite occurs, use the following guidelines
  • Allow bite to bleed freely for 15-30 seconds
  • Clean and disinfect the area
  • Stay Calm
  • Get assistance to travel to emergency medical
    care

31
Rabies and Lyme Disease
  • Rabies is a viral disease of mammals, typically
    transmitted through the bite of an infected
    animal.
  • Avoid animals that show strange behavior.
  • Lyme disease affects people who have been bitten
    by a deer tick, but failed to notice that the
    insect attached itself to them.
  • If you think you are affected by Lyme disease,
    contact a doctor right away.
