9. . Did You Know In the years 2007-2008... The average workers’ compensation cost for a slip/trip/fall was $21,500 ©2009

10. Did You Know In the years 2007-2008... The average incurred workers’ compensation cost per trip/slip/fall exceeded the average cost of other injuries by 14%.

11. Slips, Trips & Falls (STF) STF’s represents #1 cause of injury after motor vehicle accidents STF’s occur in any part of the workplace whether inside or outside. STF’s may result in serious outcomes STF’s cost to both worker and employer can be great STF’s is like stepping on money To Worker : To Employer: pain lost wages temporary or permanent disability reduced quality of life depression loss in productivity and business increased worker’s compensation premiums costs associated with training replacement worker cost of medical treatment ©2009

12. Definitions Slip Trip Loss of balance when there is too little friction between the foot and the floor Loss of balance when the foot collides with, strikes or hits an object in its path

13. ©2009 Definitions To move downward, typically rapidly and freely, from a higher to a lower level Fall

14. ©2009 Definitions Friction The resistance that one surface or object encounters when moving over another The resistance between the shoe and the walking surface

15. ©2009 Definitions A measurement that indicates how slippery a floor is under dry conditions 1-16 Coefficient of Friction

16. ©2009 Examples of COF If it takes 6 pounds of force to move a 10 pound object, then: 6 (horizontal force) 10 (vertical force) the coefficient of friction (COF) is 0.6. This is considered by floor experts to be a safe rating.

17. ©2009 Examples of COF If it takes 2 pounds of force to move a 10 pound object, then: 2 (horizontal force) 10 (vertical force) the COF is 0.2. This is considered by floor experts to be an unsafe, slippery rating.

18. ©2009  Static Coefficient of Friction—the force required to initiate relative motion between an object and a surface it is resting on  Dynamic Coefficient of Friction—the force required to keep a sliding object in motion once sliding has begun Two Types of COF

19. Slips Causes: o Slippery surfaces o Wearing the wrong footwear Two types of slips during normal walking: o As the heel of the forward foot contacts the walking surface, the foot slips forward, and the person falls backward. o The rear foot slips backward, and the person falls. ©2009

20. Slips Cont… Friction is the force that allows someone to walk without slipping. Traction is the adhesive force between the walking surface and the sole of the shoe The higher the friction, the better the traction: o Low traction: icy, wet, oily, or waxed surfaces o Higher traction: dry concrete or other dry surfaces Use of slip resistant footwear can reduce slips and the resultant falls and injuries. ©2009

21. Trips Cause: o Sudden stop caused by foot striking an object, throwing the upper body forward. Examples: o Un-level walking surfaces, even as minor a difference as 3/8 inches o A slight difference in a stair can cause a fall up the stairs ©2009

22. Trips Cont… Step and fall o Front foot lands lower than expected (i.e. stepping off a curb) o Normally falls forward o Turning an ankle results from stepping on an uneven surface ©2009

23. Common types of STF Injuries: Sprains, strains Bruises, contusions Fractures Abrasions, lacerations ©2009

24. Commonly affected Body Parts: Knee, Ankle, Foot Wrist, Elbow Back Shoulder Hip Head ©2009

25. Recognizing Slip, Trip and Fall Hazards

26. ©2009  OSHA Regulatory Requirements  Voluntary Consensus Standards  NFPA  ANSI  ASTM  NFSI  Individual State Building Codes Regulations and Standards

27. ©2009  Responding to incidents when they occur  Putting out fires  Taking corrective action after an incident occurs  Placing blame after an incident  Fixing symptoms Reactive or Proactive Proactive Reactive  Identifying hazards before they cause an incident  Correcting systems  Taking corrective action before an incident occurs  Finding root causes after an incident  Fixing problems

28. Many STF Events Can Be Prevented According to the U. S. Department of Labor, slips, trips, and falls make up the majority of general industry accidents. 25% of reported w/c claims per fiscal year are due to STF Over 17% of all disabling work injuries are the result of falls ©2009

29. Risk Factor Categories Environment Equipment Work PracticesIndividual Risks in the work environment Risks inherent in the equipment employees use Risks that are caused by work requirements, processes or procedures Risks unique to the individual, including inherent characteristics, habits and behavior ©2009

30. Where Do Hazards Lurk

31. Human Factors Increasing the Risk of Slips, Trips and Falls Health and physical condition can impair a person’s vision, judgment, and balance. - Eyesight, visual perception - Age - Physical state, fatigue - Stress, illness -Medications, alcohol, drug Behaviours – actions you choose and control can contribute to a slip, trip, and fall injury if you set yourself up for one. Carrying or moving cumbersome objects, or too many objects, that obstruct your view impair your balance and prevent you from holding onto handrails Poor housekeeping (allowing clutter to accumulate, not maintaining clean dry floors, etc.) Using improper cleaning methods (e.g., incorrectly using wax or polish; or trying to clean up grease spill with water) Not using signage when slip or trip hazards exist Inattentive Behavior: walking, distractions (e.g., using cell phone, talking and not watching where you’re going, etc.) Taking shortcuts; not using walkways or designated, cleared pathways; being in a hurry, rushing around ©2009

32. Elevated Falls vs. Same Level Falls Same Level More Frequent Less Severe Usually involves slips or trips Elevated Less Frequent More Severe Involves Striking an object during a fall Over 60% are from less than 10 ft. ©2009

33. Evaluating Slip, Trip and Fall Hazards

34. ©2009 Causes of Slips, Trips and Falls

35. ©2009  Floor material  Floor finish  Floor texture and pattern  Floor slope  Floor contaminants  Floor condition  Environmental conditions  Footwear of person  Footstep of person Factors of Floor Slipperiness

36. ©2009 The James Machine Photo used with permission from the National Floor Safety Institute A machine that measures the static coefficient of friction of a floor finish. This is the measure of how slip resistant a finish is. Also known as ASTM test method D2047. The sufficient James Machine reading to indicate slip resistance is 0.5 or greater.

37. ©2009 Horizontal Drag Meter Photo used with permission from the National Floor Safety Institute This machine, a drag sled, measures the point at which a horizontal force acting upon a resting object first causes the object to move. For consistent results, the horizontal pulling force is applied through a small motor connected by nylon cord. May be used on wet surfaces.

38. ©2009 BOT-3000 Photo used with permission from the National Floor Safety Institute Portable tribometer designed to provide readings relating to static and dynamic coefficient of friction on both wet and dry surfaces.

39. ©2009 Portable Inclinable Articulated Strut Photo used with permission from the National Floor Safety Institute A portable inclinable articulated strut slip tester (PIAST) measures friction at the shoe and floor interface.

40. ©2009 English XL Photo used with permission from the National Floor Safety Institute The English XL measures the static coefficient of friction (SCOF) of a particular surface, either dry, wet or in the presence of contaminants in order to determine the relative safeness of the surface in relation to the accepted standards adopted by ASTM, ANSI, and UL.

41. ©2009 General Rule Slips and trips happen frequently, but tend not to be severe. Falls happen infrequently, but tend to be severe.

42. ©2009 Controlling Slips, Trips and Falls

43. ©2009 Engineering Controls Controls that are engineered into the job—most important type of control

44. ©2009 Types of Engineering Controls  Redesign of equipment  Substitution of a material, equipment or process  Change of process to minimize slips, trips and falls  Use of barriers to isolate a hazard  Use of barriers to isolate a person

45. ©2009 Making Floors Slip Resistant Apply slip-resistant floor treatments. Use floor mats. Apply floor skid strips to steps and stair nosings.

46. ©2009 Administrative Controls Controls that change the way people do their jobs—only effective when people do what they are supposed to do

47. ©2009 Types of Administrative Controls  Education and training  Signage  Adjusting work schedules or rotating assignments to reduce exposure  Maintenance  Good housekeeping  Contracting specialized services

48. ©2009 Personal Protective Equipment Controls that protect people from the hazard rather than eliminate the hazard

49. ©2009 Types of PPE  Slip-resistant shoes  Fall arrest equipment  Hard hats  Goggles  Nets  Roll bars  Safety platforms
