Wear eye protection, leather gloves, thick-soled boots and a respirator rated for the dust, add hearing protection for extended hammering and a hard hat under any overhead structure, and never take a building apart alone: one person works while one watches and listens from outside. Agree two exit routes and a stop signal before you start, and keep both exits clear of tools and debris.
Part of Building Material Recovery
Demolition injuries come from small, repeated exposures as much as from collapse: nails, splinters, glass, dust and fatigue. Protective gear, a partner and a planned exit deal with most of them.
The Commonest Injuries Are Small Ones, And Gear Prevents Them
Minimum protective gear for salvage (parent article):
- Eye protection. Safety glasses or goggles, non-negotiable. A nail flying from a pried board can blind you.
- Gloves. Leather work gloves for splintered wood, rusty nails, broken glass and rough metal.
- Footwear. Steel-toe or thick-soled boots. Nails pointing up from discarded boards are the most common salvage injury.
- Respiratory protection. An N95 at minimum for any dusty work; P100 for suspected asbestos or mould. See Asbestos, Lead Paint & Other Hazards.
- Hearing protection. Earplugs from pharmacies or industrial suppliers, if hammering extensively.
- Head protection. A hard hat if working under an overhead structure.
What You Need
- The gear above, checked before each session.
- A partner, with a whistle, a horn or a pot to signal.
- A first-aid kit and clean water at the site; see Wound Management.
- A plan for the exits.
Method: Plan, Pair, Clear, Stop
Step 1: Fit the gear. Check that the respirator seals on your face. A beard or a loose fit lets dust round the edges.
Step 2: Brief your partner. Agree the signal for “stop and come out” and the signal for “I am hurt”. The outside partner watches and listens (parent article); they do not enter to help unless it is safe.
Step 3: Fix the exits. Identify two exit routes before starting. Keep them free of tools, boards and debris.
Step 4: Work from the top down and from the outside in. Take down light, non-structural items first and keep each load path in mind; the structural rules are on Structural Safety Assessment.
Step 5: Manage the debris. Remove or bend over nails as you go. Stack boards on the ground, nail side down or pulled. Never leave a board with nails pointing up where someone will step.
Step 6: Control the work area. Keep spectators and children away from the building and the pile. Do not let two people swing tools in the same space.
Step 7: Work in short sessions. Tired people make errors. Rest, drink water and re-check the structure after each break.
Common Mistakes
- Taking off gloves for a fiddly job. Splinters and cuts follow.
- Working alone because “it is only a small job.” Small jobs hurt people too.
- Leaving the exit as a storage area. The exit is for leaving.
- Skipping the respirator because the dust looks light. Fine dust is the harmful kind.
- Continuing after hearing a new sound. Stop and look first.
Safety
Falling material, flying nails and dust cause most demolition injuries
Pulling a board can send a nail or splinter toward your face, and pulling a member can drop what it supported. Wear eye protection every time, never stand beneath what you are loosening, and never remove a member that carries load without supporting it. Treat every cut from rusty metal as needing prompt cleaning. If someone is trapped or hurt, call the stop signal and make the area safe before moving in.
