HSWA and Your Forecourt: A Pitted, Oily Apron Is Three Safety Duties at Once (NZ)

If you are the PCBU or compliance owner for a fuel site, you already carry a register of duties: certified handlers, location compliance certificate, secondary containment, signage, the hazardous-area plan. It is easy to file the forecourt surface under "maintenance" and treat it as a presentation or asset issue. Under the Health and Safety at Work Act 2015 it is not. A pitted, oily apron is a single hazard that lands on your s36 primary duty of care on three fronts at once.
This page sets out those three fronts, why a forecourt fails faster than an ordinary car park, and why a dated, by-zone repair report belongs in your safety file.
One surface, three HSWA duties
The s36 primary duty does not break the apron into three separate problems. The same patch of failed asphalt is doing three things at once.
Slips and trips. A worn, uneven, fuel-filmed surface is a slip-and-trip hazard to every customer on foot, the public included. That is a public-liability exposure as much as a worker-safety one.
Vehicle movement. A pothole or shoved mat in a refuelling lane is a vehicle-movement hazard, where consequences are highest because cars are manoeuvring among pedestrians.
Tanker operation. The hardstand has to carry a fuel tanker onto the fill points and hold it while it discharges. A failing surface at or near the fill point is a tanker-safety problem, and a delivery is the moment the hazardous area is most clearly live.
You do not get to address one and call the duty discharged. The surface either supports all three or undermines all three.
Two regimes sit over the same ground. HSWA 2015 gives you the general primary duty. The Health and Safety at Work (Hazardous Substances) Regulations 2017 add the fuel-specific layer: location compliance certificate, certified handler, signage, secondary containment and established hazardous areas. The surface touches both.
Why a forecourt fails faster than an ordinary car park
A forecourt is not a supermarket car park that sells fuel. Three causes compound, and they are why an ordinary patch blows out within a season.
Hydrocarbon attack. Petrol, diesel and oil are solvents, and the bitumen binder in asphalt is itself a hydrocarbon. Daily spills soften and dissolve the binder, concentrated directly under the nozzles and along the island kerbs. This is why a standard patch in the apron does not hold.
Heavy point loads and turning shear. Fuel tankers and heavy goods vehicles brake and pivot on the same spots, day after day. That repeated turning shear works the asphalt mat horizontally until it tears back to basecourse.
Ponding over poor drainage. Water that sits saturates the base, drops its bearing strength and accelerates potholing under the loads above.
Any "binder loss in X hours" figure you see quoted is indicative trade knowledge, not an NZ-verified statistic. The mechanism is the point: a forecourt is harsher than a car park, and the apron is its harshest part. Our asphalt pothole repair guide covers the permanent saw-cut-and-seal method that holds where ordinary patching does not.
The hazardous area changes the repair method
This is where a forecourt repair stops resembling a normal car-park job. A fuel forecourt is a classified hazardous area under AS/NZS IEC 60079.10.1:2022, with Zone 0, Zone 1 and Zone 2 around the dispensers, the tank fill and dip points, and the vents. WorkSafe NZ requires those areas to be recorded on the site's hazardous-area plan. Inside the zone, ignition sources are prohibited: naked flame, sparks, hot surfaces, non-rated electrical, even a mobile phone.
That matters because the standard tools of asphalt work are themselves ignition sources. Hot-mix runs at roughly 140 to 160 degrees, and petrol-powered plate compactors and rollers spark and run hot. So inside the zone you have two lawful paths:
use cold-mix and low-temperature, spark-free methods that introduce no ignition source; or
isolate the pump or tank, gas-test the atmosphere to confirm a safe lower explosive limit, and work under a hot-work permit before any hot process begins.
Outside the zone, on the entry and exit lanes and general parking, conventional hot-mix saw-cut-and-seal is normal. The boundary between "in zone" and "out of zone" is set by your site's hazardous-area plan, not by a number we would quote here, because the distances are site-specific and sit in a paywalled standard. The principle is the same as any car park repair: match the method to the conditions, except here those conditions are governed by a hot-work permit and a gas test.
Keeping the site selling while the surface gets fixed
A 24/7 forecourt cannot simply close, and your duty does not require it to. It requires the work to be controlled. We stage it pump by pump so fuel keeps flowing:
isolate and bag one island at a time, cone and barrier it, and keep the rest of the forecourt selling, with trafficable cold-mix returning that lane the same shift;
reserve hot-mix relay and excavation for outside the zone and for quiet or overnight windows, with a spotter managing the interface to live vehicle movement;
schedule around the tanker-delivery window, because a delivery re-establishes a live hazardous zone at the fill points;
work under your permit-to-work with a signed method statement, so nothing happens that your system has not authorised.
The practical fuel-safe sequencing lives in more detail in our forecourt repair overview, if your operations team wants the method view rather than the duty-holder view.
The repair report is a compliance record, not a receipt
This is the part that matters most to a compliance owner. When the work is done, a dated before-and-after photo repair report, organised by zone, is a genuine HSWA and liability record for your safety file. It is evidence, not a tidy extra.
If a slip claim, a vehicle incident or a tanker near-miss is ever examined, the question is whether you identified the surface hazard and acted on it. A by-zone report shows the hazard, the prepared edges, the finished surface, the method used and the date you closed it out. It maps onto the three fronts directly: the slip hazard you removed, the vehicle-movement defect you made good and the tanker hardstand you restored. That record sits alongside your location compliance certificate and hazardous-area plan as part of how you demonstrate the s36 duty was met, not assumed.
Who actually buys this depends on your site type
One practical note on who signs the order. On company-owned sites, the national property or retail-engineering team usually procures and pays for forecourt maintenance, so the report needs to reach them in a form their safety file can absorb. On dealer-owned sites, the operator is the buyer and holds the duty directly. Either way the s36 duty does not transfer with the invoice, so the record needs to live where the duty-holder can produce it.
Get a forecourt condition report
To see where your forecourt sits against these three duties, start with a free forecourt condition report. Send photos of the apron under the pumps, the fill-point hardstand and the entry and exit lanes, with the site address and your permit and hazardous-area requirements. We assess each zone, flag which defects sit inside the hazardous area and which do not, and tell you the method each one needs. You get a fixed price worked out from the photos, broken out by zone and method, with no call-out fee.
