Fall Protection During Demolition
Demolition creates fall hazards as it goes—floors get opened, edges appear and roofs lose strength—so protection has to be planned with the sequence.
Four fall thresholds to recognize
Quick-reference overview. The actual project scope, site conditions, qualified evaluations and applicable requirements control.
Tap a number
Where a fall from an unprotected edge is more than 7.5 feet, fall protection is required.
A top rail and mid rail go up along every edge the demolition opens.
Debris chute and stair openings get guardrails, and no one works below the drop zone.
Holes not in use are covered, fastened down and marked so no one lifts the cover. Openings need protection at any height.
Where an edge can’t be guarded: harness and lanyard to an anchor rated 5,000 lb per person, no more than 6 feet of free fall, and a rescue plan set first.
Skylights and weakened roof areas are screened or guarded before anyone walks the roof.

Fun facts
Three details worth remembering
- California’s trigger is 7.5 feet
Most construction work requires fall protection at 7.5 feet at unprotected edges; openings need protection at any height.
- A cover is a protective system
It has to be secured, strong enough for the loads on it and marked so no one removes it.
- Fall arrest needs a rescue plan
A worker hanging in a harness needs prompt rescue, so the plan is set before anyone ties off.
Read the detailed planning guidanceConcise, source-grounded project considerations
Survey the structure first
Before demolition starts, a qualified person surveys the framing, floors and walls for the chance of unplanned collapse, including adjacent structures where workers may be exposed. The survey is written and kept on site, and demolition stays under the immediate supervision of a qualified person.
Keep people away from the fall
The best fall protection keeps workers off weakened floors and roofs. Plan mechanical demolition where possible, work from the top down and use scaffolds or aerial lifts when members are removed by hand.
Guard edges and openings
Put guardrails at open edges and around openings created for chutes, stairs and shafts. Cover holes that are not in use with secured, marked covers, and guard skylights and fragile roof areas before anyone walks the roof.
Use personal fall protection correctly
Where edges and openings cannot be guarded, use restraint so a worker cannot reach the edge, or fall arrest with rated anchors. Inspect harnesses and lanyards before each use, train every user and set the rescue method before work begins.
