Demolition Safety Sydney What a Zero Harm Site Actually Looks Like
Every demolition contractor has a safety folder. What matters is whether it reflects what actually happens on site.
That gap between what is written and what is done is the difference between a contractor who genuinely takes safety seriously and one who ticks boxes to win work. You do not need a safety qualification to spot the difference. You just need to know what to look for.
Key Takeaways
- •A site-specific SWMS must name your address, your structures, your hazards. Generic templates do not meet the legal requirement.
- •Daily pre-start meetings are 5 to 10 minutes, every morning, with every worker present. No exceptions.
- •Dust suppression during concrete breaking is not optional. It is a legal control measure under NSW WHS Regulation 2017.
- •A contractor who claims zero near-misses is not running a safe site. They are running a site where near-misses go unreported.
- •Six things any client can observe on site, without any safety expertise, that reveal everything about a contractor’s safety culture.
What a Site-Specific SWMS Must Actually Contain
Under the Work Health and Safety Regulation 2017 (NSW), demolition is classified as high risk construction work. That means a Safe Work Method Statement (SWMS) is legally required before any work starts. Not after. Not on the first day. Before.
But here is what most homeowners do not realise: a generic SWMS is essentially worthless. If it does not name your street, your specific structures, your identified hazards, it is not compliant. A contractor who hands you a template with a different address crossed out is telling you something important about how they run their sites.
A compliant, site-specific demolition SWMS must contain these 10 elements:
The two-minute SWMS test. Ask the contractor two questions before you sign anything: “Does this SWMS name my specific address?” and “Does it reference the specific structures being demolished on my block?” If the answer to either is no, or if they cannot produce a SWMS at all, stop the conversation. SafeWork NSW is clear: the demolition licence holder must prepare a site-specific SWMS before starting any demolition work.
Daily Pre-Start Meetings: What Actually Happens
Every morning. Before any machine starts. Every worker on site. No exceptions.
That is what a genuine daily pre-start meeting looks like. It runs 5 to 10 minutes. It is not optional. And it is one of the most reliable indicators of a contractor’s safety culture. It either happens or it does not.
A properly run pre-start covers six things:
- Today’s task sequence: what is happening in what order, which structures are being touched.
- Site-specific hazards for the day: has anything changed overnight? Weather conditions? New excavation edges? Delivered materials blocking access routes?
- PPE check: every worker confirms they have the correct PPE for their specific task that day. Not a general reminder. A check.
- Emergency contacts reminder: who is the nominated first aid person today, where is the first aid kit, and what is the evacuation point.
- Hazard identification from workers: a good pre-start is not a supervisor monologue. Workers speak. They are closest to the hazards and often see things supervisors miss.
- SWMS review if work changes: if today’s task differs from what the SWMS anticipated, the SWMS is reviewed before work starts, not after.
What a good one looks like in practice: workers contributing observations, questions being answered directly, and the supervisor listening, not reading from a clipboard while workers stare at their phones. Before you sign a contract, ask: “How does your pre-start process work?” A vague answer is your answer.
On-Site Controls: What a Safe Demolition Site Looks Like
Exclusion Zones
Every active demolition site requires physical exclusion zones. These are not lines on a plan. They are installed barriers that prevent unauthorised entry into the work area. The perimeter is set by the demolition method, the height of structures being removed, and the debris throw radius. For a standard Sydney residential demolition, the exclusion zone extends to the full property boundary with the street-facing side hoarded. Exclusion zone requirements scale significantly for high-stakes commercial demolition , the controls and planning involved differ considerably. If there is no physical barrier between the machine and the public footpath, that site is non-compliant.
PPE by Task: Not Just Hard Hats
Hard hat and hi-vis vest: always, for every person on site. Beyond that, PPE is task-specific:
- Concrete and masonry breaking: P2 dust mask minimum, eye protection, hearing protection (hydraulic hammer operation exceeds 85dB, the mandatory action level under WHS Regulation).
- Manual material handling: cut-resistant gloves, steel-capped boots.
- Working near active machinery: increased exclusion zone, spotter deployed.
- Work near boundaries or overhead obstructions: eye protection mandatory.
Workers wearing only hard hats and hi-vis during active concrete breaking. That is not a compliant site.
Dust Suppression
From 2024, SafeWork NSW increased scrutiny of crystalline silica exposure on demolition sites. Concrete breaking produces respirable crystalline silica dust. It is invisible. It causes silicosis, which is irreversible. A compliant site runs a water cart or pressurised sprinkler system during all concrete and masonry breaking. Not sometimes. Every time. Visible dust clouds leaving the site boundary are both a WHS breach and a public health issue.
Housekeeping
End of each day: no loose debris at path edges, no unsecured material, skip bins not blocking access, exclusion fencing intact, site hoarding secure. A site that looks like a tip at 4pm every afternoon is a site where the supervisor has stopped looking.
Near-Miss Reporting: The Most Honest Safety Indicator
Incident reports tell you what has already gone wrong. Near-miss reports tell you whether a contractor is honest enough to document what almost went wrong.
There is a well-established pattern in workplace safety research, often referenced as Heinrich’s Triangle, that describes the relationship between near-misses and serious incidents. For roughly every serious injury, there are dozens of minor incidents and hundreds of near-miss events. A worksite that never records near-misses is not a safe site. It is a site where near-misses go unreported.
A contractor who proudly tells you they have had zero near-misses is not telling you they run a perfect site. They are telling you their workers do not report. That is a red flag, not a selling point.
The question to ask before you hire:
“Tell me about a near miss on a recent job and what you did differently after it.”
A good answer looks like:
Specific incident named. Immediate corrective action described. Systemic change explained. The discomfort in sharing it is actually a positive sign. It means they have thought about it seriously.
A concerning answer sounds like:
Defensive. Vague. Changes the subject. “We train our workers really well so that sort of thing doesn’t happen.” These responses tell you near-miss reporting either doesn’t exist or nobody uses it.
Asbestos requires its own specific safety protocols that go well beyond standard demolition controls. For the full detail, see our asbestos and hidden hazards guide.
Six Things You Can Observe on a Safe Demolition Site
You do not need a safety background to assess a contractor’s safety culture once work begins. These six things are visible to anyone.
Site fencing is intact and access is controlled. No open gates.
Every access point should be gated and either locked or supervised at all times during work. An open gate means unauthorised entry is possible. That is a site security failure and a public liability issue. If you see it once, raise it. If you see it repeatedly, it is a cultural problem.
Workers are wearing task-appropriate PPE, not just the basics
Watch what workers are wearing when they are actually doing the work. Concrete being broken without hearing protection or dust masks means the SWMS is not being followed on site, whatever it says on paper.
A water cart or sprinkler is running during concrete breaking
Dust suppression is active, not passive. If breaking is happening and there is no water being applied, crystalline silica is entering the air. You can see this from the footpath, or the absence of it.
Waste is in skips or managed stockpiles, not loose on the footpath
A skip bin is part of the site control plan. Loose demolition material on or near a public footpath is a hazard and a breach of council requirements. Debris left on the footpath overnight. Raise it directly with the contractor.
The site supervisor is visibly in charge, not just standing on a phone
Under NSW regulations, a named supervisor must be present during licensed demolition work. Presence means actively supervising. The supervisor should be observable, accessible, and directing work when decisions are being made.
Any worker can tell you the emergency contact number
Ask any worker on site, not the supervisor. “If there was an incident right now, who would you call?” If they know immediately, the pre-start is working. If they hesitate or look at each other, the daily safety briefing is not delivering.

Frequently Asked Questions
Work With a Contractor Who Means It
Safety documentation and real safety culture are two very different things. Our SWMS is site-specific. It names your property, your structures, your hazards. Our pre-starts happen every morning. Our dust suppression runs every time the hammer touches concrete. Ask us for a sample SWMS as part of your quote process.
