10. 10 Ladder Safety

11. 11 DO NOT USE SUCH LADDERS Damaged or Defective Ladders Missing rung

12. 12 Securing Ladders Secure ladders to prevent accidental movement due to workplace activity Only use ladders on stable and level surfaces, unless secured Do not use ladders on slippery surfaces unless secured or provided with slip-resistant feet This ladder is not on a stable surface

13. 13 When using a portable ladder for access to an upper landing surface, the side rails must extend at least 3 feet above the upper landing surface Ladder Rail Extension

14. 14 Ladder Angle Non-self-supporting ladders: (which lean against a wall or other support)  Position at an angle where the horizontal distance from the top support to the foot of the ladder is 1/4 the working length of the ladder

15. 15 Face the ladder when going up or down Use at least one hand to grab the ladder when going up or down Do not carry any object or load that could cause you to lose balance Climbing the Ladder

16. 16 Three Point Contact

17. 17 Don’t Work on the Top Three Rungs

18. 18 Secure the Ladder at Top

19. 19 Face the work Activity

20. 20 Fall Hazards

21. 21 Unprotected edge Unprotected Sides & Edges Unprotected sides and edges must have guardrails or equivalent

22. 22 Sides & Edges - Improper Guarding This 1/4" nylon rope alone is not a proper way to guard this open floor

23. 23 Holes more than 6 feet high must be protected This opening could be made safe by using a guardrail, or strong cover Sky Lights and Other Openings

24. 24 Cover completely and securely If no cover, can guard with a guardrail Floor Holes Improperly Covered

25. 25 If you work near wall openings 6 feet or more above lower levels you must be protected from falling Wall opening Wall Openings

26. 26 Safety Harness GuardrailsSafety Net Fall Protection Options

27. 27 Top rails between 39 and 45 inches tall Toeboards at least 3 1/2 inches high Top Rail Mid- Rail Toeboard Guardrails

28. 28 Place as close as possible, but no more than 30 feet below where employees work Safety Nets

29. 29 SAFETY HARNESS

30. 30 Safety Harness in use

31. 31 Fall protection systems and work practices must be in place before you start work. Lanyards and PFAS in use Fall Protection

32. 32 What Is A Scaffold?

33. 33

34. 34 Hazards Falls from elevation – caused by slipping, unsafe access, and the lack of fall protection Struck by falling tools / debris Electrocution – from overhead power lines Scaffold collapse - caused by instability or overloading Bad planking giving way Employees working on scaffolds are exposed to these hazards:

35. 35 Fall Hazards While climbing on or off the scaffold Working on unguarded scaffold platforms When scaffold platforms or planks fail Falls may occur:

36. 36 Falling Object Protection l Wear hardhats l Barricade area below scaffold to forbid entry into that area l Use panels or screens if material is stacked higher than the toeboard l Build a canopy or erect a net below the scaffold that will contain or deflect falling objects

37. 37 l Can use PFAS instead of guardrails on some scaffolds l Use PFAS & guardrails on suspension scaffolds l Use PFAS on erectors and dismantlers where feasible Fall Protection Requirements The ends of this scaffold are not properly guarded

38. 38 Overhead Power Lines The possibility of electrocution is a serious consideration when working near overhead power lines Check the clearance distances listed in the standard

39. 39 Supported Scaffolds Platforms supported by legs, outrigger beams, brackets, poles, uprights, posts, & frames Restrain from tipping by guys, ties, or braces Scaffold poles, legs, posts, frames, and uprights must be on base plates and mud sills or other firm foundation This support is not adequate!

40. 40 Scaffold Support Examples Good supportInadequate support – in danger of collapse? Base plate Mud sills

41. 41 No large gaps in front edge of platforms Each abutted end of plank must rest on a separate support surface Overlap platforms at least 12 inches over supports, unless restrained to prevent movement Scaffold Platform Construction Planks not properly overlapped

42. 42 Avoid the Main Hazards of Scaffolds Falls from elevation Bad planking Scaffold collapse Getting struck by falling tools or debris Electrocution

43. 43 Scaffold Inspection Defective parts must be immediately repaired Deformed bearer

44. 44 Safety Harness

45. 45 Install along open sides & ends Front edge of platforms not more than 14 inches from the work, unless using guardrails and/or PFAS Top rails - 38 to 45 inches tall Midrails halfway between toprail and platform Toeboards at least 3-1/2 inches high Guardrails

46. 46 Scaffold Access No access by crossbraces When using ladders, bottom rung no more than 24 inches high Can use some end frames Can access from another scaffold, structure or hoist End Frame Do not access by crossbraces

47. 47 Proper Scaffold Access Provide access when scaffold platforms are more than 2 feet above or below a point of access Permitted types of access: Ladders, such as portable, hook- on, attachable, stairway type, and built-ins Stair towers Ramps and walkways May use building stairs and come out window

48. 48 Dangerous Conditions Fix slippery conditions before using. Stairway parts must be free of projections which may cause injuries or snag clothing.

49. 49 Guard excavations more than 6 feet deep when they are not readily seen because of plant growth or other visual barriers Excavations In addition to needing guarding, this excavation is not properly shored

51. 51 Electrical Safety

52. 52 Electrical Shock Can be Fatal..

53. 53 Electrical Hazards and How to Control Them Electrical accidents are caused by a combination of three factors: –Unsafe equipment and/or installation, –Workplaces made unsafe by the environment, and –Unsafe work practices.

54. 54 Hazard – Exposed Electrical Parts Cover removed from wiring or breaker box

55. 55 Grounding Grounding creates a low-resistance path from a tool to the earth to disperse unwanted current. When a short or lightning occurs, energy flows to the ground, protecting you from electrical shock, injury and death.

56. 56 Clues that Electrical Hazards Exist Tripped circuit breakers or blown fuses Warm tools, wires, cords, connections, or junction boxes GFCI that shuts off a circuit Worn or frayed insulation around wire or connection

57. 57 Safety-Related Work Practices Use special insulated tools when working on fuses with energized terminals Don’t use worn or frayed cords and cables Don’t fasten extension cords with staples, hang from nails, or suspend by wire.
