Title: Safety in the Swine and Poultry House


1
Safety in the Swine and Poultry House
  • Respirators give real protection
  • wear tight-fitting NIOSH approved respirators as
    necessary
  • Guards on fans and motors prevent accidents
  • keep fingers, hands away from moving parts
  • Winches can be risky - be careful
  • gears, cable, spinning handles can cause injury
  • Be cautious during electrical work and storm
  • eliminate electrical hazards and minimize
    exposure to shock
  • Supervise children in poultry houses
  • poultry houses are not playgrounds

2
Hazards in Animal Housing
  • Air Pollutants in Animal Housing
  • Dust and Other Aerosols
  • Ammonia
  • Hydrogen Sulfide
  • Other Gases
  • Odors
  • Air Quality Control and Management
  • Mechanical Hazards
  • Electrical Hazards
  • Noise
  • Fire
  • Children in Buildings
  • Safety Signs

3
Air Pollutants in Animal Housing
  • Dust and Other Aerosols
  • Dust found in animal housing is primarily
    composed of
  • Feed components
  • Dry fecal material
  • Dander (hair and skin cells)
  • Molds
  • Pollen
  • Grains
  • Insect parts
  • Mineral ash
  • some components may cause allergic responses
  • an important air quality problem in poultry and
    livestock housing

4
Dust Control
  • Proper waste management and ventilation
  • Minimize poor indoor quality - animals and
    workers
  • workers are required to wear appropriate personal
    protective equipment when entering these
    facilities
  • particularly mask or respirators
  • Several methods of reducing dust are under
    evaluation
  • Wet , electrostatic, cyclonic and dry dust
    filters
  • Oil sprays
  • spraying vegetable oil
  • bind up the dust particles and keep them out of
    suspension

5
Ammonia ( NH3 )
  • Ammonia is produced by bacterial action on urine
    and feces during decomposition
  • Comes off of the floors and from the manure pits
  • Levels in animal buildings can be sufficiently
    high to affect human health
  • Ammonia control
  • Frequent removal of waste
  • Management of indoor moisture
  • Adequate ventilation
  • ventilation dilutes ammonia concentration and
    tends to dry floors and litter
  • reduces the rate of ammonia release

6
Hydrogen Sulfide ( HS )
  • Is an acutely toxic gas produced by the
    decomposition of animal manure
  • Often released into the air when liquid manure is
    agitated
  • Its odor is not an indication of its
    concentration
  • Above 6 ppm the odor increases as concentration
    also increases
  • The OSHA limits exposure to 10 ppm for an 8 hour,
    5 day exposure
  • At levels above 50 ppm human evacuation is
    recommended
  • Levels above 500 ppm cause unconsciousness and
    death
  • Levels increase to 1500 ppm when swine pit manure
    is agitated

7
Hydrogen Sulfide ( HS ) (continued)
  • Workers should wear a self contained respirator
    if exposure to HS is expected
  • Hazards created during manure agitation can be
    controlled by
  • Providing ventilation during manure pumping
  • Removing the manure
  • Preferable when
  • people and animals are absent from the building

8
Other Gases
  • Methane ( CH4 )
  • A natural product of manure decomposition
  • nontoxic
  • High concentrations produces
  • dizziness and even asphyxiation
  • Flammability of methane Main Safety Concern
  • CH4 can be explosive at concentrations over
    50,000 ppm
  • valuable as an energy source
  • NIOSH (National Institute of Occupational Safety
    and Health) recommended Daily exposure
  • 1,000 ppm per 8 hour work period
  • Control
  • proper ventilation generally dissipates methane
    from animal housings

9
  • Carbon Dioxide ( CO2 )
  • Produced by manure decomposition and animal
    respiration
  • nontoxic gas
  • High concentrations can cause
  • asphyxiation by reducing available oxygen
  • Concentrations in well ventilated buildings can
    range
  • 1,000 ppm during summer
  • 10,000 ppm during winter
  • OSHA (Occupational Safety and Health
    Administration) permissible exposure level for
    CO2
  • 10,000 and 30,000 ppm respectively per 8 hour
    and 15 minutes work period
  • Control
  • proper ventilation
  • CO2 control is important in cold climates

10
  • Carbon Monoxide ( CO )
  • Product of the incomplete combustion of
    hydrocarbons
  • its colorless, odorless, and has nearly the same
    density as air
  • CO hazards in animal production operations caused
    by
  • combustion heaters malfunction
  • operational heaters or internal combustion
    engines
  • without venting the combustion products outdoors
  • Winter Most dangerous period
  • buildings are usually closed and ventilation
    rates are at its lowest
  • OSHA and NIOSH recommended threshold limit values
  • 40mg/m3 or 35 ppm for an 8 hour work period
  • Control
  • combustion heaters and engines should always be
    vented to the outside

11
Odors
  • Air Quality Control and Management
  • Unpleasant odors have long been associated with
    domestic animal production
  • Installation and operation of a well-designed
    ventilation system is the producers best
    assurance of adequate indoor quality
  • provides thorough air mixing
  • eliminates dead spaces having stagnant air
  • moves fresh air through the housing facility
  • Ventilation vents should open enough to provide
    high velocity jets to ensure thorough air mixing
  • Summer months
  • evaporative cooling is needed using misting
    systems to reduce the indoor air temperature
  • Winter months
  • supplemental mixing fans are needed because
    ventilation rates are reduced to a minimum

12
Air Quality Control and Management (continued)
  • Prevention and early detection of toxic gas
    levels reduces health risks
  • installs CO detectors near combustion heaters
  • the heater should be vented to the outside
  • clean the heater thoroughly at the beginning of
    each heating season
  • while in use, monitor the heaters daily to ensure
    that they burn efficiently and produce minimal
    levels of CO
  • Use extreme caution during manure removal
  • manure slurries will release hydrogen sulfide
    rotten eggs
  • cause for concern
  • HS can quickly inure the sense of smell as
    concentrations increase and become deadly
  • Control dusts
  • during cold weather, use feed additives (oil,
    fat, and lecithin) to help reduce dust emission
    from feed meals.

13
Mechanical Hazards
  • Fans
  • unguarded fans are dangerous, must have guards or
    screens so people cannot touch any moving parts
  • Winches
  • workers operating winches must be careful to
    avoid releasing the winch before the object is
    fully raised or lowered
  • accidentally striking a winch under tension can
    cause it to release
  • Augers
  • must be properly guarded
  • before any maintenance the equipment must be
    unplugged, or switched off at the control and
    breaker box
  • Steel Cables
  • worn or frayed could produce gashes and puncture
    wounds on hands
  • wear a sturdy pair of work gloves to prevent
    these wounds
  • Housing Floors
  • can be slippery and obstructed by equipment and
    railings
  • use a good pair of work boots to prevent falls
    and foot injuries

14
Electrical Hazards
  • Due to faulty electrical wiring
  • Risk of shock
  • Potential for fire
  • Destruction of good equipment
  • motors and pumps
  • Use wiring practices that protects electrical
    cable and system components
  • from abuse by livestock and rodents
  • avoid exposure to tractors and feeding equipment
  • Appropriate design and reliable installation of
    electrical systems are crucial to
  • use electricity efficiently
  • provide a safe environment for workers and
    animals
  • minimize the potential for fire loss

15
Noise
  • Sound levels are measured in decibels (dB)
  • Soft whisper is about 30 dB while a 120 dB will
    cause pain
  • OSHA limits noise exposure to 90 dB over an 8
    hour shift
  • Tractors and other farm machinery cause the most
    noise
  • in livestock housing - animals and machinery
    produce significant noise
  • swine buildings - at feeding time 115 dB can be
    reached

16
Fire
  • Factors that facilitate fire in livestock
    buildings
  • Poor management and maintenance, improper storage
    of combustibles, unsafe electrical wiring and
    lightning
  • Reduce fire incidents
  • Construct building with fire retardant materials
  • Combustibles - discard from building those not
    frequently used
  • store frequently used in a fire retardant
    compartment
  • Use wiring material and equipment meeting the
    requirements of the National Electric Code
  • Electrical equipment should be installed
    according to manufacturers specifications
  • All electrical equipment (fuses, junctions, and
    outlet boxes) should be kept free of grease and
    dust
  • Place 10 lb ABC type fire extinguishers in all
    major buildings near exits

17
Children in Buildings
  • Animal production facilities are attractive
    playgrounds to children
  • Because of their complexity and potential for
    danger
  • no one should treat animal production facilities
    as play areas
  • lack of experience
  • makes children vulnerable to injuries in
    agricultural environments
  • young children visiting these facilities
  • should be supervised by trained production
    personnel
  • older children should be allowed to work in these
    environments
  • providing adequate training and with parental
    supervision
