Ladder Safety for Aussie Homes (the Bits That Get People Killed)
I’ll skip the joke this article because this is the one where I take it seriously. Falls from ladders are the number-one home renovation injury in Australia per Safe Work Australia data, and the bit nobody tells you is most of those falls happen under 2 metres — gutter height, downlight height, the “she’ll be right, I’m only up here a second” height. None of it is a dramatic 6-metre roof fall. It’s the second rung of a step ladder while changing a light bulb. My mate Trev took a fall off a 1.8 m step ladder in his own garage three years back — broken wrist, two screws, six weeks off work. Hospital trip from gutter height.
Right, here’s the thing. I do home maintenance every day and I’ve had two close calls in 25 years — both on ladders, both because I cut a corner I knew about. Since then I have a four-rule pre-climb check that takes about 30 seconds and I’ve never had a third close call. Boring as it is, that’s the article. Plus the Aussie-specific stuff: tile roofs, the 100 kg trap, the stand-off bracket requirement, and which brands are actually rated for trade use here. If you read nothing else, read Step 1 and Step 5. Those two prevent most of what hurts people.
What you’ll need
- The right ladder for the job — see Step 2, this is where most decisions go wrong
- A ladder rated for your bodyweight plus tools, with margin (Step 3 explains the 100 kg trap)
- Stand-off bracket / ladder stay if you’re going on a tile or metal roof gutter
- Non-slip footwear — tradie boots, not thongs, not Crocs, not socks
- A tool belt or bucket-on-rope so you climb with two hands free
- A second person at the base for any climb above 3 m, no exceptions
- A helmet if you’re going above 3 m or under any low overhead
Step 1: The four-rule pre-climb check (memorise this)
Before you put weight on any ladder, every time:
- Footing — both feet on level, hard, dry ground. No grass. No mulch. No wet concrete. Uneven ground, use a ladder leveller, not a stack of bricks.
- Angle — extension ladders go at 1:4 (one out for every four up). Step ladders open fully, spreader bars locked.
- Lock — extension ladder rung locks engaged on both rails. Step ladder spreader bar fully extended and rigid.
- Top — if leaning, the top must rest on something rigid that won’t break. NOT a tile. NOT a gutter. NOT a fly screen. NOT a downpipe.
Thirty seconds. If any of the four fails, stop and fix before you climb. Single check prevents about 90% of the bad ones. Don’t be that bloke who skipped the check to save 30 seconds.
Step 2: Pick the right ladder for the job
Most people own one ladder and try to make it do everything. That’s where injuries start. Rough rule:
- Step ladder (1.5-2.5 m) — interior work, light bulbs, ceiling fans, painting cornices. Self-supporting, no wall needed.
- Extension ladder (3.5-6 m) — gutter cleaning, eaves painting, fascia repair. Needs a structure to lean on.
- Platform ladder — if you’re going to be up there more than ten minutes (cornice painting, electrical work). Platform stops your feet cramping and balance going.
- Multi-fold (Little Giant style) — versatile, but heavy and only as safe as your patience for re-locking the joints.
If you’re at the limit of a step ladder for an outdoor job, you’ve picked the wrong ladder — get an extension.
Step 3: Aussie ladder ratings — the 100 kg trap
This is the gotcha that gets people, specifically Australian. AS/NZS 1892.5 rates step ladders by working load limit (WLL). Most domestic step ladders sold at Bunnings — Ozito, Bailey Pro Punchlock domestic range, most no-name aluminium — are rated to 100 kg WLL. That’s user PLUS clothing PLUS tools PLUS materials. A 95 kg adult holding a 4 L paint pot (5 kg) is at 100 kg before you count boots and a tool belt. He’s already over. Industrial / trade-rated step ladders are 120 kg or 150 kg WLL — usually fibre-glass rather than aluminium. The two brands actually rated and trusted for trade use in Aussie homes are Trojan and Branach. Bailey’s Pro range goes there too. If you weigh over 90 kg or carry tools, do not buy a 100 kg ladder. Cost difference is $50 once. Cost of a fall is the rest of your life.
Step 4: Tile roof access — stand-off bracket is not optional
If you are accessing a tile roof — to clean a gutter, fix a TV antenna, repaint a chimney — leaning your extension ladder against the gutter is not legal under AS/NZS 1892.1, and physically it’s daft. Tile-roof gutters sit on tile edges. Tiles snap. Gutters bend. Your top rail slips sideways and you’re going down. You need a stand-off bracket (ladder stay, wall stay) that fits over the top and pushes contact points 250-400 mm clear of the gutter, onto the roof tiles themselves spread across multiple tiles, or onto the wall above the gutter. Bunnings sells them, Bailey makes a good one around $80. Trojan makes a heavier-duty one worth the upgrade if you do this regularly. No bracket, no tile-roof access. Period. If you’re heading up there to clean Colorbond or check the gutters, get the bracket fitted before you climb.
Step 5: Three points of contact — every move
Two feet plus one hand, OR two hands plus one foot, on the ladder at all times. Means: never carry tools up by hand. Tool belt or bucket on a rope hauled up after you. Never reach more than an arm’s length sideways — your belt buckle should stay between the two ladder rails, always. Have to reach further, climb down and move the ladder. Every. Single. Time. The two close calls I had were both me reaching just one more inch sideways. Both times the ladder twisted. Both times I caught it. The third time I won’t. Fair dinkum, this is the rule that’s saved me.
Step 6: Don’t climb above the third rung from the top
On an extension ladder, the top three rungs aren’t for standing. Handrails need to be above your hips for balance — feet on the top rung, rails are below your hips and there’s nothing to hold or fall against. On a step ladder, the top step (“THIS IS NOT A STEP” stickered platform) is not for standing on either. If the ladder isn’t tall enough, get a taller ladder. Not an area for improvisation. Bunnings hires extension ladders by the day if you don’t want to own a 6 m unit — about $35 for 24 hours.
Step 7: Wet, windy, or after-dark — don’t go up
Aluminium ladders on wet concrete slip. Wind catches you sideways at gutter height — a 40 km/h gust at 4 m up is more force than you’d believe. After-dark you can’t see ground irregularities or slick spots. None of these jobs are emergencies. Wait for tomorrow morning. Eight hours of patience versus a fortnight in hospital isn’t a hard maths problem.
Step 8: Set up an exclusion zone if anyone else is home
If kids, partner or pets are home, tape off the base of the ladder or close the gate. The bit that gets people isn’t usually slipping themselves — it’s the dog running underfoot at the moment they were committing weight. Or a kid coming through the door you didn’t see. Set the zone, tell the household, then climb.
Step 9: Inspect the ladder before every use
Look at the rails for dents, splits, corrosion. Aluminium ladders dent if they’ve fallen — dents become stress points. Fibre-glass ladders crack under UV exposure if left in the sun for years (rails go fuzzy, fibres exposed — that ladder is done). Check rung locks engage. Spreader bars lock fully. Feet rubbers not worn smooth. A 10-second look before each climb catches failures that won’t show up till you’re 4 m up. Same maintenance mindset as extension cord and powerboard safety — equipment that protects you from injury needs checking before every use.
Step 10: For anything above 3 m, second person at the base
Cost of getting a mate over is a beer. Cost of being found alone with a broken hip in the side yard is two hours of nobody knowing where you are. Any extension ladder work above 3 m — gutter cleaning, antenna, fascia — have someone at the base footing the ladder. That’s the difference between a slip and a fatality. If you’re cleaning gutters and noticed wear elsewhere, the pressure-washing safely guide covers the same PPE thinking.
When to call a tradie
Listen mate, alot of “DIY” roof jobs aren’t DIY. Two-storey-plus (over 6 m) is a roofer’s job — they have harness systems and edge protection. Same for steep-pitched roofs (over 25 degrees), tiled roofs 15+ years old (tiles brittle, walk on them and they snap), and anything where you’d need to step off the ladder onto the roof itself. Roofers and gutter cleaners charge $250-500 for a job that would put a homeowner in hospital. That’s not pessimism, that’s the actuarial reality.
Common screw-ups
- Wrong WLL rating. 100 kg domestic ladder for a 95 kg user with tools = overloaded. Get a 150 kg trade-rated.
- Leaning extension on a gutter. Gutter bends, rail slips, you go down. Stand-off bracket required.
- Reaching sideways. Two close calls in 25 years for me, both reaching. Climb down, move the ladder.
- Standing on the top three rungs. Nothing to hold, nothing to fall against. Get a taller ladder.
- Wet or windy conditions. Aluminium slips, wind takes you sideways. Wait for the next morning.
Cost & time
Trojan 150 kg fibreglass step ladder $250-400. Bailey extension ladder $300-600 depending on length. Stand-off bracket $80-150. Ladder hire from Bunnings or Kennards $35-70/day for an extension. Time per safety check: 30 seconds. Time saved by skipping the check: zero, because the check itself is 30 seconds. Time saved by getting the right ladder for the job: hours, every job.
The Mick wrap
Four-rule check, three points of contact, never the top three rungs, never on a tiled gutter without a stand-off bracket, and never alone above 3 m. The ladder doesn’t kill people. Shortcuts on the ladder kill people. There is no job that’s worth skipping the check. My mate Trev still climbs ladders, just slower and with the check now. He says the screws in his wrist ache when it’s about to rain, which is a useful weather forecaster but a rubbish reminder of a 30-second oversight. Don’t be that bloke. Take the half-minute.
