3.  Scaffolding – Without assistance, students will identify the three different scaffolds and the parts of a supported scaffold without error.  Hazards – without assistance, students will be able to recognize improper uses, and construction in scaffolding, without error.  Remediation/Inspection - without assistance, students will be able to identify the traits of a competent person and a qualified erector, without error. Forward

4.  In the construction industry last year there were 828 fatalities, of which 302 were due to falls.  36.5% of all construction fatalities could be prevented by you the Constructor.  Safe working platforms and proper fall protection saves lives!! Next

6. An elevated, temporary work platform Three basic types:  Supported scaffolds -- platforms supported by rigid, load bearing members, such as poles, legs, frames, & outriggers  Suspended scaffolds -- platforms suspended by ropes or other non-rigid, overhead support  Aerial Lifts -- such as “cherry pickers” or “boom trucks” Next

7. 1. Handrails: top rail at 38” to 48” 2. Mid-rails: half way between the top rail and the platform 3. Toe boards: at lest 3 1/2” tall 4. Platform: scaffold plank must be 2” thick and OHSA approve plank 5. Scaffold feet: no rust and in good working order 6. Scaffold bucks: not bent or damaged 7. X-bracing: no damage and properly placed 7 5 6 1 2 4 3 Next

8.  Platforms suspended by ropes or wires.  Rope must be capable of supporting 6 times the load  Train employees to recognize hazards Secure/tie to prevent swaying  Support devices must rest on surfaces that can support four times the load  Competent person  evaluate connections to ensure the supporting surfaces can support load  inspect ropes for defects before shift  PFAS must have anchors independent of the scaffold support system  https://www.youtube.com/watch?v=D4JY9a ffLdo https://www.youtube.com/watch?v=D4JY9a ffLdo Next

9.  Daily inspections of all mechanical and moving parts  Must use outriggers when operating boom or deck  Must operate lift on a level surface  Must wear fall protection when in the basket or work platform  https://www.youtube.com/watch?v=CUD gxNfSjGI https://www.youtube.com/watch?v=CUD gxNfSjGI Next

10. Please take a screen shot of this slide, and print and turn in at the end of the PowerPoint. Instructions: Fill in the box with the name of the scaffold part where the arrow is pointing. Next

11. What is the correct range of height for a scaffolding top rail? Click on proper response. A.32” to 36”A.32” to 36” B.36” to 38”B.36” to 38” C.38” to 48”C.38” to 48”

13. The top rail of a scaffold is built between 38” to 48” off the platform.

14. OSHA requires for a suspended scaffold’s rope or wire must be capable of supporting __ times its weight. A.4 times4 times B.6 times6 times C.10 times10 times

16. Rope and cable must be capable of supporting 6 times the load!

17. When operating a boom lift (Ariel Platform) you need to wear personal fall protection. True False

18. You must wear fall protection when operating an Ariel lift.

20.  Employees working on scaffolds are exposed to these 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 Next

21.  Falls may occur:  While climbing on or off the scaffold  Working on unguarded scaffold platforms  When scaffold platforms or planks fail  https://www.youtube.com/watc h?v=p729z_u7Cug https://www.youtube.com/watc h?v=p729z_u7Cug Next

22. Falling Object Protection:  Wear hardhats  Barricade area below scaffold to forbid entry into that area  Use panels or screens if material is stacked higher than the toe board  Build a canopy or erect a net below the scaffold that will contain or deflect falling objects  https://www.youtube.com/wa tch?v=bWqFIfAfdeQ https://www.youtube.com/wa tch?v=bWqFIfAfdeQ Next

23.  No paint on wood platforms  Use scaffold grade wood  Fully planked between front upright and guardrail support  Component pieces used must match and be of the same type  Erect on stable and level ground  Lock wheels and braces Next

24. 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 Next

25. The possibility of electrocution is a serious consideration when working near overhead power lines Check the clearance distances listed in the standard Next

26. Reflect on the Hazards Module and make a short List of 5 Hazards in working with the three different types of scaffolding, and what you have to do to remedy the Hazard. Example: Hazard – Hit in the head by a falling object. Remedy – Always wear hardhat when on a construction site. Bring your list with you to the next OSHA class. Next

27. When Building a supported scaffold the scaffold does not have to be built on stable and level ground? Click on proper response. True False

29. Next

30. You always have to wear a hard hat when working on or around a scaffolding. Click on proper response. True False

31. Next

33. When building a scaffold you can use what ever type of lumber you want for planking. Click on the proper response. True False

36. Competent person inspects scaffolds for visible defects before each shift and after any alterations Defective parts must be immediately repaired Next

37.  Person capable of identifying and promptly correcting hazards  Determines if it’s safe to work on a scaffold during storms or high winds  Trains workers to recognize hazards  Selects qualified workers to conduct work Next

38. Scaffolds can only be erected, moved, dismantled or altered under the supervision of a competent person Competent person selects & directs these workers and determines the feasibility of fall protection Next

39. Train employees on scaffold hazards and procedures to control the hazards The training must include:  Nature of electrical, fall, and falling object hazards  How to deal with electrical hazards and fall protection systems  Proper use of the scaffold  Scaffold load capacities Retrain as necessary Next

40. Train employees involved in erecting, disassembling, moving, operating, repairing, maintaining, or inspecting a scaffold to recognize its hazards and the correct procedures to use Next
