Types of Agricultural Risk

1. Production risk

– Weather, pests, equipment breakdowns, etc.

2. Marketing risk

– Uncertainty in the market for your product

3. Financial risk

– Ability to pay the farm’s cash obligations in a timely

manner (liquidity) and protect or grow your equity

(solvency)

4. Legal risk

– Possibility of being sued, fined or penalized

5. People risk (a.k.a. human resources risk)

– The four D’s – death, divorce, disability & disagreement

4

Responsibilities Under OSHA Act

• A farmer who employs one or more persons has….

– To comply with the agricultural safety standards;

– To comply with record keeping and other reporting

responsibilities, such as reporting accidents, posting of a

citation, etc.; and

– To comply with the general duty clause

• which states that every employer must furnish each employee a place

of employment free from all recognized hazards causing or likely to

cause death or serious injury

• Immediate family members are not covered by the act

• Does not prevent personal injury lawsuit from being

filed against farmer on behalf of the injured

5

What is a Hazard?

• A hazard is anything that could hurt you or make you sick

Cut you Trip you Burn you Crush you

U.S. Statistics - Agriculture

• 1,202,000 full-time + 1,978,000 part-time workers

employed in production agriculture (U.S. Ag Census, 2012)

• One U.S. farmer produces food and fiber for 155 people (American Farm Bureau, 2009)

• Each day, 243 agricultural workers suffer lost-work-time-

injuries; 5% result in permanent impairment

• Slips & falls are the leading cause of farm-related injuries

• Unlike most industries, farm family members are also at risk for injuries, illnesses & deaths

U.S. Death Rates by Industry (BLS, 2013)

Reference: http://www.bls.gov/news.release/pdf/cfoi.pdf

Note: Fatal injury rates exclude workers under the age of 16 years, volunteers, and resident military.

10

U.S. Annual Statistics - Agriculture• 590+ farmers & ranchers die in work-related

accidents

• 88,700+ ag workers suffer disabling injuries

from work-related accidents (under-reported)

• 115+ youth die on farms (34% are age 16-19),

most as

– Innocent bystanders

– Passengers on farm equipment

• 17% of all farm injuries are caused by animals

• Over one-third of farm tractors have no ROPS

with seat belts

11

Did You Know That….

• The fatality rate for farmers is 700% higher than

for other American workers?

• Tractors are the leading cause of death on farms?

• The most frequent causes of tractor-related

deaths are side and rear overturns?

• 80% of deaths caused by rollovers happen to

experienced farmers?

12

Did You Know That….

• 1 in 7 farmers involved in a tractor overturn is

permanently disabled?

• 7 out of 10 farms will go out of business within a

year of a tractor overturn fatality?

• When used with a seatbelt, rollover protective

structures (R0PS) are 99% effective in preventing

injury or death in the event of an overturn?

13

Farmers’ Perceptions

• Inconvenience

• "Never happen to me"

• Independence

• No reward

• Added cost

• Number of hazards

• Habits

• Self-image

14

Errors = Accidents

• Forgot something

• Took a shortcut

• Took a calculated risk

• Ignored a warning

• Used unsafe practices

• Was preoccupied

• Didn’t see hazard

15

Common Agricultural Hazards• Equipment (tractors, machinery, ATVs, mowers)

• Terrain (slips & falls)

• Ergonomics (lifting, repetitive trauma)

• Noise (tractors, chain saws, shop equipment)

• Respiratory (dusts, molds, toxic gasses)

• Chemicals (pesticides, fertilizers, fuels)

• Animals (temperment, handling facilities)

• Biologicals (vet medicines, zoonoses)

• Stress & fatigue (lose concentration & focus)

• Skin exposures (sun, heat, chemicals, microbes)

Child Farm Safety

• Children can be exposedto dangerous situations24 hours a day on the farm

• The farm is both a workand home environmentfor many families

• Without a separation between the two environments, children can be exposed to tremendous risks

Set Up Safety Rules

1. Designate safe play areas

2. Determine other areasthat might attract children

3. Identify dangers with children

4. Be a role model for safe practicesPhoto credit: http://nasdonline.org

20

1. Designate Safe Play Areas

• Identify locations where children can play with minimal adult supervision

• Designated areas protect children by isolating them from farm work

• Fencing can help to reinforce the division between work and play

• Provide appropriate play items so that the area is more enticing than the farmstead

21

2. Determine Other Attractions

• Discuss with children where they like to play on the farm and why

• This will help you to identify potential problems and help you to explain why some of these areas are off-limits and dangerous

• Use lots of examples of how children can be injured in your explanation

22

3. Identify Dangers with Children

• Once the play area has been established, walk with your children through the farming operation and point out potential hazards

• Explain what makes these areas dangerous

• Tour should include machinery and equipment, livestock pens, fields, farm buildings, grain and storage areas, and workshop

23

Machinery & Equipment

• This area is most dangerous when tractors and other machines are in operation

• Adults may not be able to see or hear others in area

• Children should never enter areas where machinery is in operation unless supervised, or machinery is turned off

24

Livestock

• Children are often fascinated by livestock and may perceive them to be as familiar as stuffed animals to be played with

• Children might not understand or perceive the subtle signs an animal will exhibit just before attacking

• The average difference in body weight between a child and an average farm animal makes crushing injuries common

25

Farm Buildings / Workshop

• Confined spaces such as silage structures can hold a buildup of toxic gases

– Smaller amounts of these toxins are needed to cause injury to children than adults

• Workshops and storage areas contain hand tools, chemicals (pesticides, oils, cutting fluids), electrical outlets, sharp or hot items

4. Be a Role Model for

Safe Practices

26

27

Dangers of Used Equipment• Are operating manuals included?

• Are shield and guards in place?

– PTO master shield, starter solenoid cover,

steering components

• Is the equipment in decent condition?

– No narrow front end

– Slow-moving vehicle (SMV) emblems, working lights

• Is tractor equipped with a

Roll-Over Protective Structure

(ROPS) and seat belt

– Required since Oct. 1976

28

Prepare Yourself

• Read the operator’s manual

• Consider training from one experienced

with the equipment you are using

• Good physical & mental condition

• No medications or alcohol

• Proper protective gear

What is a Power-Take-Off (PTO)?

• The PTO provides a means of transmitting power between a tractor and another piece of farm machinery

• A few examples of PTO-driven equipment:

– Hay balers

– Rotary cutters

– Sickle mowers

– Forage blowers

– Irrigation pumps

– Generators

58

Balers Have Many Danger Zones

Turn off equipment before service or repair

59

Haying Equipment Safety Rules 1

• General

– Read the operator’s manual (again)

– Keep alert - drink plenty of liquids, eat regular meals,get enough sleep, take breaks

– Replace broken or worn parts

– Make sure all guards and shields are in place

– Always disengage PTO, shut off tractor engine and pocket ignition key before dismounting to service or adjust the equipment

– Avoid rushed movements when working close to sharp edges

– Always lubricate sprockets and chains when the machine is turned off

– Be prepared for a fire with 10-lb. Class ABC fire extinguisher on all tractors, charged and in working order

60

Haying Equipment Safety Rules 2

• Mowers– Wait until all cutter bars, reels, or conditioning rollers have stopped

moving before servicing

– Ensure proper clearance between crimping rollers on mower conditioner

• Square balers– Wait for flywheel to stop before servicing

• Round balers– Make sure twine is properly threaded, twine arm is adjusted, and in

good working condition. Do not feed twine by hand into the baler

– Always lock and block the baler’s rear gate if you must be underneath it

• Forage wagons– Stay clear of the discharge conveyor while operating

Hearing Loss Indicators

� Do you have trouble hearing when two or more people are talking?

� Do you have trouble hearing over the telephone?

� Do others complain you turn the TV volume up too high?

� Do you strain to understand conversations?

� Do you have trouble hearing if the background is noisy?

� Do you frequently ask people to repeat themselves?

� Do you think people mumble frequently?

Rule of Thumb:

If you need to raise your voice to be heard an arm’s length

away, the noise is loud enough to damage your hearing.

Ergonomics

• Ergonomics is the study of efficiency in working environments, matching workers and job conditions to avoid injuries

• Preventing pain or injuries caused by:

– Working in a stooped position

– Carrying heavy weights in awkward positions

– Kneeling often

– Working with arms above shoulder level

– Moving hands and wrists repetitively

– Vibration from farm equipment

76

Ergonomic Guidelines – Hand Work

• Avoid placing needed tools or other items above shoulder height

• Position items that are used often within 17” of the worker’s body

• Alternate repetitive work with a low-repetition task to allow recovery

• Provide seated jobs to reduce the strain on lower back & legs

• Alternate sitting, standing and walking jobs

• Allow adequate clearances for feet and knees, so workers can get close to the work and avoid reaching

• Provide floor mats for standing work stations to reduce fatigue

• For standing work, use the proper work station height

– Men: 40” to 43” for light work, 36” to 39” for heavy work

– Women: 37” to 39” for light work, 33” to35” for heavy work

77

Ergonomic Guidelines – Hand Tools

• When tools require force, handle size should allow the worker to grip all the way around the handle so that the forefinger and thumb overlap by 3/8”

– Handle diameter of 1-3/8” for small hands to 2-1/8” for large hands, with an average of 1-3/4”

• Cover handles with smooth, slip-resistant material (plastic or rubber).

• Dual-handled tools (like shears or pliers)

– Handle length of at least 4” and preferably 5”

– Spring return to maintain an open position

– Handles that are almost straight without finger grooves

– Handle diameter large enough for small overlap of thumb and fingers

78

Ergonomic Guidelines - Lifting

• Keep lifts between hand level and shoulder level. Avoid lifts

from the floor or over shoulder level

• Provide handles on containers

• Redesign loads so they can be lifted close to the body

• Provide dollies, pallet trucks, or utility carts for objects that have to be carried more than a few feet. Provide roller conveyors for heavy bags or boxes that are handled often

• Keep bag or box weight below 50 pounds

79

Ergonomic Guidelines – Stooped Work

• Redesign the job to avoid stooped work

– Attach long handles to tools

– Provide stools

• If stooped work is required, provide employees with other short tasks that require walking or sitting, to break up the amount of time spent in stooped position

80

Ergonomic Guidelines – Vehicle Use

• Reduce whole body vibration by equipping tractors and other vehicles with suspension seats that have appropriate vibration-damping characteristics

• Use motor vehicle seats with good seat positioning and lumbar support

Anti-vibration gloves
