Why Fall Protection Matters

Falls are the #1 cause of death in construction. In fact, one in three construction fatalities is from a fall. The good news is that falls are preventable when you use proper fall protection.

When Fall Protection is Required

OSHA requires fall protection when working at heights of 6 feet or more above a lower level. This includes work on:

  • Roofs
  • Scaffolds
  • Ladders
  • Elevated platforms
  • Steel erection
  • Near holes, skylights or openings
  • Leading edges
  • Wall openings

Types of Fall Protection Systems

1. Guardrail Systems

  • Physical barriers that prevent falls
  • Must be 42 inches (±3 inches) high
  • Must withstand 200 pounds of force
  • Must have midrails and toe boards when necessary
  • Common at roof edges, floor openings, and on scaffolds

2. Safety Net Systems

  • Catch workers who have fallen
  • Installed as close as possible below the work area
  • Must be tested or certified
  • Must have enough clearance to prevent hitting objects below

3. Personal Fall Arrest Systems (PFAS)

A personal fall arrest system consists of three key components:

  • Anchor point - Secures the system to the structure
  • Connecting device - Lanyard or lifeline that connects your harness to the anchor
  • Full-body harness - Distributes fall forces across your body

4. Warning Line Systems

  • Visual barriers set back from the edge
  • Only for roofing work on low-slope roofs
  • Not a physical restraint - just a warning
  • Must be combined with other protection when working outside the warning line

5. Hole Covers

  • Must support twice the weight of workers, equipment, and materials
  • Must be secured to prevent accidental displacement
  • Must be marked with the word "HOLE" or "COVER"

Using a Personal Fall Arrest System

Your Harness

  1. Hold by the back D-ring and shake to untangle straps
  2. Slip straps over shoulders like a vest
  3. Connect chest strap and adjust it to fit snugly
  4. Connect leg straps and adjust for a snug fit
  5. The D-ring should be centered between your shoulder blades
  6. You should be able to stand up straight with all straps snug but comfortable

Your Lanyard

  1. Connect only to the back D-ring of your harness
  2. Secure to an anchor point that can support 5,000 pounds
  3. Keep lanyard as short as possible to minimize fall distance
  4. Never tie knots in your lanyard - this weakens it
  5. Protect your lanyard from sharp edges
  6. Use shock-absorbing lanyards when possible

Inspection Before Each Use

Check for:

  • Frayed or damaged straps
  • Broken stitching
  • Rust or damage on metal parts
  • Damaged or missing parts
  • Impact indicators showing a fall has occurred
  • Proper function of buckles and connections

What to Do If You Fall

If you're hanging in your harness after a fall:

  1. Stay calm
  2. Try to reach a safe surface if possible
  3. Push against any nearby structure to maintain blood circulation
  4. Move your legs to prevent blood pooling
  5. Call for help
  6. If you have one, deploy your suspension trauma strap

Remember: Hanging motionless in a harness for too long can cause serious injury. Rescue planning is a critical part of any fall protection program.
