3. Objectives
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.

4. Why do we need safe work Platforms?
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!!

6. What Is A Scaffold? 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. Parts of a Supported Scaffold
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 4 1 2 3 7 5 6
Next

8. Suspended Scaffoldings
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
Next

9. Ariel Lifts 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
Next

10. Supported Scaffold Activity
Instructions: Fill in the box with the name of the scaffold part where the arrow is pointing.

Please take a screen shot of this slide, and print and turn in at the end of the PowerPoint.

11. Review Question 1
What is the correct range of height for a scaffolding top rail? Click on proper response. A. 32” to 36” B. 36” to 38” C. 38” to 48”

12. Incorrect
Please try again

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

14. Review Question 2
OSHA requires for a suspended scaffold’s rope or wire must be capable of supporting __ times its weight.
4 times
6 times
10 times

15. Incorrect
Please try again

16. Rope and cable must be capable of supporting 6 times the load!
You are Correct
Rope and cable must be capable of supporting 6 times the load!
Next

17. Review Question 3 True False
When operating a boom lift (Ariel Platform) you need to wear personal fall protection.
True
False

18. You are Correct
The answer is true. You must wear fall protection when operating an Ariel lift.

19. Incorrect
The answer was True. You must wear personal fall protection when in the lift.

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

22. Struck By 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
Next

23. Scaffold Platforms/Planks
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. Scaffold Collapse
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. Electrocution
The possibility of electrocution is a serious consideration when working near overhead power lines Check the clearance distances listed in the standard
Next

26. Reflection
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.
