* Residential Fall Protection
http://my.habitat.org/collection/g355af/HFHI-Fall-Protection-Statement
OSHA Fall Protection “new” Directive created June 2011
HFHI created a Fall Protection Statement paper March 2011
http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=DIRECTIVES&p_id=4755
*Residential Fall Protection Objectives:
• Discussing the Requirements• Methods of Safe Practices in…
• Truss Installation• Sheathing Installation • Paper & Shingling Installation
• Various Fall Protection processes will be reviewed…• Personal Fall Arrest Systems (PFAS)• Scaffolding• Guardrails• Holes• Ladders• Leading Edge
• Competent Person Requirements• OSHA Training Requirements
*Residential Fall Protection Why use OSHA Regulations? We use volunteers & OSHA does
not apply to us, right?
• It is an agreed upon process of “how to do it safely”
• Regulations are unfortunately written in blood & by blood
• Why recreate the whole safety process?
• It is the right thing to do!
• We haven’t paid an insurance claim when done safely – Only when lacking safety!
• Your safety policy may be compared to OSHA CFR 1926 Construction Manual as “bare minimum” or as “reasonable care” to worker safety
*Residential Fall Protection Truss
Installation • Bracket Scaffolding / Carpenters Scaffolding
• Top plate acts like to top rail• Fall distance is less then 6 ft.• Can install inside or outside• Optional guardrail can be used• 18” walk plank• 8’ between brackets• Not to exceed 500 Lbs.• Not to exceed 2 workers per 8’• Overlap plank on brackets by 6” to
12”
*Residential Fall Protection
Adjustable Bracket Scaffolding
• Notice the optional guardrails installed behind worker
*Residential Fall Protection Wall Walker
SystemHooks over top plate
Adjustable height for plank
Optional Guardrails
*Residential Fall Protection Other systems to
consider
Safety Features:
• Ladder access to platform• Scaffold grade lumber for
platform.• Feet set on level ground.• Guardrail around platform.
Safety Features:
• Poles set at regular intervals to support platform.
• Regular geometric bracing to support the poles.
• Safety guardrail around the platform.
Safety Features:
• Scaffold grade lumber used for the platform.
• Ladder access to platform.
• Aluminum support poles within every 50 ft.
Safety Issues:
• Unsafe support materials used to support the platform (hay).
• Unsafe ladder access to work platform.
• Unsafe bracing for support for platform (slanted wood beams).
• Not level work platform.• No safety rail surrounding
the work platform.
Safety Issues:
• No large safe work platform only a couple of wood beams.
• Unsafe ladder access provided (unsecured ladder access).
• Flimsy bracing materials provided to support platform.
Safety Issues:
• Unsafe and non regular support provided for the work platform.
• No ladder access provided.• Guardrail does not protect
all sides of the work platform.
Safety Issues:
• No work platform provided just a plank to sit on.
• Non level work platform.• Unsafe support material
provided for the scaffolding.• Human labor is all that is
holding the scaffolding in place.
*Residential Fall Protection Ladders for Trusses
Ladder Rules Apply!!!• Never exceed top 2 steps• Never lean too far L / R• Install guardrails at
windows & doors as necessary
• Open stepladders fully• Inspect ladder before use• Good ladder footing• Keep ladder base clean &
clear• Keep ladder rungs clean• Don’t exceed ladder weight
limit• Don’t climb on ladder
braces
*Residential Fall Protection
Platform Ladder Scaffolding
Real Name = Trussle Ladder • Notice how the center section extends
upward• Guardrails hook on to the ladder rungs• Platform sits on the ladder rungs

*Residential Fall Protection
“Baker” Narrow Scaffolding
Notice – when wheels are added the scaffold becomes titled as “Mobile Scaffold”
*Residential Fall Protection
What about the “middle man” truss safety?
Best Answer: Truss Spreader Bar (TSB)
*Residential Fall Protection
• 2 Truss Spreader Bars are required (TSB)• 1 Full Body Harness is required• 1 Retractable (Yo Yo) Lanyard is required
• End wall truss and other 2 next trusses are set from ladders (10 or 12ft. ladder may be necessary)
• 1st TSB is secured to end wall truss and next 2 trusses, #2 & #3
• “Middle man” is now able to connect to the TSB anchor• Set truss 4 & 5, secure necessary braces as normal• Install 2nd TSB onto truss 3, 4 & 5 • Middle man will now re-hook from TSB #1 over to TSB
#2• “Leapfrog” the 2 TSB’s as work progresses
*Residential Fall Protection Notice the “Leapfrogging” of the 2 TSB’s

*Residential Fall Protection Let’s Review Ladder Safety
• Inspect all ladders for damage or missing parts
• Red Tag and remove faulty ladders from area
• Never exceed upper ladder limits i.e. last 2 steps
• Never allow anyone to climb on braces of ladders
• Always open a stepladder fully before use
• Ladder footing must be solid
• If ladder footing is not level – dig out the high side to level a ladder – never shim up the low side
*Residential Fall Protection Ladder Safety
continued• Always use the 4:1 angle rule
• Always keep the belt buckle within the rungs
• Always tie off a ladder when exiting to another level i.e. roof or scaffolding
• Extend ladder 3 ft. above exiting point i.e. roof or scaffold
• Avoid using Aluminum ladders if possible, these ladders don’t mix with Electricity
• Always face a ladder while climbing or using it
*Residential Fall Protection
Let’s Review Ladder Safety
What’s Wrong?
What’s Wrong with These Pictures?
*Residential Fall Protection Scaffolding
Safety• Installed on firm, solid surface• Level (use levelers if possible), never
use shim materials i.e. cinder blocks, wood…
• Inspected before use & after adverse weather
• Not to exceed 14 inches from work surface
• Provide proper access (1st step 24” or less)
• Guardrails @ 10’ (better @ 6’)• Work surfaces full decked• All cross braces installed• Stacking pins secured• Keep clear of power lines (3’, 10’, 15’)• Use good quality of planking (can’t
deflect greater than 1/60 of length)• Overlap planks on supports by 6” /
12”
*Residential Fall Protection Scaffolding Safety
• Base plates on each leg (maybe secured)?
• When wheels are installed you now have a “mobile scaffold”
• Wheels must be locked when in use• Area must be free of debris & holes• Wheels must be secured to scaffolding• Secure items or materials on
scaffolding when moving
What’s Wrong with These Pictures?
*Residential Fall Protection
Holes & Covers
• Must be secured from accidental movement• Must contain the word “hole or cover” or brightly painted• Must withstand 2 x’s the expected weight that can be applied• “Hole” is any opening 2” x 2” in size• You can install a “guardrail” or “warning line” around opening.
However if an item can get kicked to a lower level you will need to install “toe-boards”
Competent Person must oversee all high hazard areas
• Fall Protection • Scaffolding• General Electrical • Stairways• Ladders• Trenching / Excavation
What is, or Who is, a Competent Person?
• Has years of experience in the trade area • Has knowledge of rules & regulations per subject
area• Has documentation of knowledge level• Has full authority to stop work & make safety
corrections• Has knowledge of safety equipment installations &
limitations

Level• Has full knowledge of CFR information• Has successfully pass written /hands on testing• Has knowledge of external equipment rules & regulation
i.e. manufacture information, etc.• Understands installation practices of related equipment i.e.
Fall Protection, Scaffolding, Ladder…• Understands limitations of related equipment
General Awareness Level
• Has good understanding of related information• Can demonstrate proper procedures• Understands their own safety role for successful outcome• Understands limitations of selected equipment • Understands proper usage of selected equipment
End-user Level
• Understands their safety role for successful outcome• Understands limitations of selected equipment• Understands proper usage of selected equipment
