BLR’s Safety TrainingPresentations

Fall Protection in Construction 29 CFR 1926.500-503


Goals

Fall hazards and basic fall protection systems Guardrails and personal fall arrest systems Quiz


Construction Fall Statistics

Leading cause of construction industry fatalities

150-200 workers are killed from falls each year

100,000 are injured from falls each year


Protecting Workers from Fall Hazards

Assess where fall protection is needed

Select fall protection systems

Properly install fall protection systems

Follow safe work procedures

Train construction workers


When Is Fall Protection Needed?

6 feet or more above a lower level

Hazard of falling into dangerous equipment

Specific areas or activities


Safe Work Practices

Pick up tripping hazards Be aware of your location Always use fall protection Avoid dropping objects Never run Listen for verbal warnings


Warning Line System

Consists of ropes, wires, chains Must be flagged every 6 feet Must be 34-39 inches above working surface Stanchions must not tip over easily Must be erected at least 6 feet from

the fall hazard Workers must be trained to stay out


Safety Monitoring System

Competent person monitors safety of workers

Recognizes fall hazards

Warns workers of fall hazards and unsafe work practices

Keeps unauthorized workers out of work area

Workers promptly comply with safety monitor


Controlled Access Zones

Keep unauthorized workers out Allow leading edge work without

fall protection systems Are designated and clearly marked work areas Lines run the length of the unprotected edge Lines are 6-25 feet away from

unprotected edge


Safety Net System

Installed under walking/working surface <30 feet below workers Inspected for

wear, damage Installed with

sufficient clearance

Items that fall into the net removed


Goals



Guardrail Systems

Top rails must be 39-45 inches above the walking or working surface

Top rails must withstand 200 lb force

Mid-rails must be between top rail and working surface

Toe boards must be 3.5 inches

Screens must be installed from top rail to working surface


Guardrail Systems

Openings must be 19 inches or less Rails must be smooth with no projections When guardrails are

removed at hoisting areas, personal fall arrest systems shall be used

Holes, excavations, and ramps must be protected


Prevent Falling Objects

Use screens or panels Store materials 4 feet from edge For roofing work, store material

6 feet from edge Use canopies strong enough to prevent

collapse and prevent penetration Keep tools, materials, and debris picked up Don’t throw objects down to lower levels Wear a hard hat


Uses for Personal Fall Arrest Systems

6 feet above a lower level

Worker positioning Worker restraint Climbing ladders,

scaffolding, rebar


Effective Fall Arrest System

Maximum arresting force of 1,800 lb Free fall no more than 6 feet Avoid contact with a lower level Max deceleration distance of 3.5 feet Designed to withstand twice the impact forces


Harness vs. Body Belt

Body belt not used for fall protection since January 1, 1998

Body belt may be used as worker restraint

Harness distributes arresting forces

Harness can be used for fall arrest, positioning, or suspension


Connectors and Snaphooks

Snaphooks lock in place Nonlocking snaphooks are prohibited Do not engage snaphooks to the following

–Webbing or rope–Another snap hook–D-ring with another snaphook attached–Horizontal lifeline–Object incompatible in shape or dimension


Lanyards

Connect harness to lifeline or anchor

Stretching or tearing system absorbs shock

Prevent bouncing to reduce arrest forces

No knots or wrapping around sharp objects


Lifelines

Lifelines connect personal fall arrest system to anchor

Vertical—hang from one anchor point Horizontal—stretched between

two anchor points Ropes and straps made of synthetic fibers Protect against being cut or abraded


Deceleration Device

Dissipates energy during fall arrest

Rip-stitch, tearing, or stretching lanyard

Rope grab device

Retracting lifelines or lanyards


Anchor Points

Anchors used only for personal fall arrest systems

Anchors support 5,000 lb per person

Located directly above you Do not tie to a guardrail Ask if unsure about

proper anchor points


Inspecting Personal Fall Arrest Systems

Inspect before each use Check D-rings for

cracking, breaking, deformation

Check straps for cuts, tears, abrasions, torn stitches

Ensure that parts move freely Remove defective components

from service


Rescue Plan

Limit suspension time

Suspension trauma occurs when legs are immobile in an upright position

Push legs against objects

Get legs up to head


Goals



Summary

Learn to recognize and minimize fall hazards Be able to erect, maintain,

and disassemble fall protection Use and operate fall protection systems Inspect fall protection systems Protect others from falling objects


Quiz

2. How tall is the top rail of a guardrail system?

3. When do items that have fallen into safety nets need to be removed?

4. Warning lines must be flagged at 6-foot intervals. True or False

5. What type of work is commonly done in a controlled access zone?


Quiz (cont.)

6. Name two things you can do to prevent objects from falling to a lower level.

7. What do you look for when inspecting your harness and lanyard?

8. Your personal fall arrest system must limit free fall distance to 8 feet. True or False

9. How do lanyards reduce arresting forces from a fall?

10. Guardrails make effective anchor points for personal fall arrest. True or False


Quiz Answers

1. Working 6 feet above a lower level

2. 39-45 inches above working surface

3. As soon as possible and at least before the next shift

4. True

5. Overhand bricklaying


Quiz Answers

6. Screens, store materials 4 feet from edge, canopies, toe boards, pick up tools and debris

7. Check straps for tears, abrasions, loose stitches; check D-rings for cracks, deformities

8. False, 6 feet

9. Stretching or tearing system absorbs shock and prevents bouncing

10. False, only use anchors that are designed for personal fall arrest systems.
