BackgroundBackgroundFarm machinery entanglements:
comprise one third of all farm machinery injuries.involve both sexes and all ages.cause an average of ten deaths per year.seriously injure another 275 people per year.

Other Machinery Injuries Entanglements
Entanglement injuries are among the most traumatic events seen in hospital emergency departments. – Major lacerations– Crushed or fractured
limbs– Amputations– Head and spinal cord
injuries– Permanent disability
Machinery hazardsMachinery hazardsEntanglement can occur
when a machine has one or more of the following hazards:
pinch pointcrush pointwrap pointpull-in pointshearing, cutting points
Pinch pointPinch point
Two or more parts move together with one moving in a circle.
Example:pulley belt
Crush pointCrush point
Two components move toward each other.
Example:three-point hitchhydraulic cylinder
Wrap pointWrap point
Exposed, rotating components. (Nicks, mud or rust increase wrap potential.)
Example:PTO shaft auger
Pull-in pointPull-in pointMechanism designed to
pull in crops or other material.
Example:baler pick-upcombinefeed grinderconveyor
Shearing, cutting pointsShearing, cutting pointsTwo parts move across
each other, or one part moves across a stationary object.
Example:cutter baraugerfeed mixerfan blade
Learning from experience: Learning from experience: Accident/incident analysisAccident/incident analysis
Immediate causePossible contributing factors– Human– Mechanical– Environmental
Basic, “systemic” causeWhat one thing could prevent a similar incident?
Case StudiesCase StudiesStories of real people injured in farm machinery entanglements. Why highlight injuries rather than fatalities?– For every entanglement
fatality, there are 2727 serious entanglement injuries.
– What survivors tell us can help prevent a similar incident.
Case Study 1Case Study 1
Erwin Lehmann
Approximately 125 people suffer serious head and/or spinal cord injuries in farm machinery related incidents every year.

Case Study 2Case Study 2Doug Thoms
Over thirty people a year suffer injuries that require admission to hospital as a result of becoming entangled in a baler.

Case Study 3Case Study 3
Bernard Bigoraj
Approximately 275 people a year are seriously injured when they become entangled or caught in a farm machine. Over 5% of all farm work-related injuries are initiated by a trip or fall.

Almost sixty women a year are seriously injured in incidents involving farm machinery.

Case Study 5Case Study 5Richard Polkinghorne
Approximately 50 people a year are killed or seriously injured when they become entangled in a power-take-off device.

Bob Ellenor
Most farm fatalities occur during daylight hours, and there are clear peaks during the afternoon, from 2:00 to 6:00 pm.

Case Study 7Case Study 7
Charlene Gray
On average, every year three people lose all or part of an arm, another two lose a hand, and almost fifty lose a thumb and/or fingers in farm work-related injuries.

Case Study 8Case Study 8Lorraine Klassen
On average every year nine children under the age of fifteen are killed, and over 100 are seriously injured in incidents involving farm machinery.

Case Study 9Case Study 9Tony Potoreyko
Fewer than half of farm fatalities are witnessed; 36% are not discovered for more than an hour, which has a huge impact on the survival rate of the victims.

What is “acceptable risk?”What is “acceptable risk?”There is only one person who can decide what level of
risk is acceptable for you. Ask yourself :
– Is the comfort of a loose shirt on a hot day worth eleven weeks in hospital?
– Is saving a few bushels of grain worth losing an arm?– Are the family hassles you avoid by letting your child ride on
or play around equipment worth losing the child?– Is getting by on three hours sleep to finish harvest a day earlier
worth losing the farm?– Is the convenience of leaving the tractor running while you
repair or unplug equipment worth your family losing you?

A management tool that can minimize the risk of injuries and maximize productivity and profitabilityCost/benefit analysis process: What will it cost - in terms of time,
money and convenience - to change equipment, the environment or a work procedure?
Is the potential benefit worth the cost?
ConclusionConclusionYou can work safely with farm machinery. Here’s how:
1. Guard or shield all moving parts.
2. Do a pre-operational safety check on yourself.
3. Disengage PTO, turn off engine and remove keys before dismounting tractor.
4. Turn off power before you repair, adjust or unplug machinery.
5. Walk around, don’t climb or reach over a rotating PTO.
6. Consider yourself a high-risk worker and dress for the job.
7. Communicate effectively when you work with another person.
8. Keep bystanders and children away from machinery.
9. You may want to invest in a Remote control engine shut-off and receiver remote control engine shut-off.
