7 Things Australian Arborists and Tree Crews Should Know About UV in the Canopy

7 Things Australian Arborists and Tree Crews Should Know About UV in the Canopy

Tree work keeps you out in the open, at height, for the whole shift — and the only shade on site usually belongs to the tree you’re about to take down. EcoZinc Natural Mineral Sunscreen SPF50 Clear is the 100% mineral, chemical UV filter free sunscreen made in Rocklea, Brisbane for Australian outdoor workers, available in 100g for the harness and 1kg and 2kg pumps for the crew truck. Here are seven sourced facts every Australian arborist, tree lopper and vegetation crew should know about UV on the job.




1. SafeWork NSW puts sun exposure on the tree work hazard list — right next to falls and power lines


SafeWork NSW defines tree work as lopping, pruning, thinning, felling and removal, and lists sun exposure among the common causes of injury in the trade, on the same list as falls from heights, being struck by falling objects and working around power lines (SafeWork NSW, Tree work (arboriculture)). Its working-in-the-sun guidance for tree crews is task-specific clothing, a hat, SPF 30+ sunscreen, lip balm and wraparound sunglasses. EcoZinc Natural Mineral Sunscreen SPF50 Clear is a broad-spectrum SPF50 mineral zinc sunscreen, which sits above that SPF 30+ minimum and drops straight into an arborist’s existing PPE and sun protection controls.




2. Standing in a tree’s shade removes far less UV than most tree crews assume


ARPANSA states that for most of the day there is as much scattered solar UV coming off the sky as there is coming from the direct sun — so stepping into a shadow only takes away part of the dose. ARPANSA also notes that a heavy, dense canopy can provide up to 90% UV protection, while a light canopy provides poor protection. That is the arborist’s problem in one line: the canopy you’re pruning is thinning as you work, and the moment you’re roped into the top of the crown or lifted out in an EWP, you’re above the shade entirely. EcoZinc Natural Mineral Sunscreen SPF50 Clear in 100g fits a harness pocket or a ute door pocket for exactly those hours.




3. Solar UV is a classified carcinogen, and the workplace damage is counted every year


ARPANSA reports that ultraviolet radiation is classified by the International Agency for Research on Cancer (IARC) as carcinogenic to humans, and that approximately 200 melanomas and 34,000 non-melanoma skin cancers are diagnosed in Australia each year from UV damage received in the workplace. Safe Work Australia’s Guide on Exposure to Solar Ultraviolet Radiation puts the acute end of it plainly: in Australia, sunburn can occur in as little as 11 minutes on a fine January day. Eleven minutes is less time than it takes to drop a limb and feed it through the chipper.




4. Winter jobs and early starts do not get a tree crew under the limit


ARPANSA advises that even when the UV Index is below 3, sun protection is still recommended for outdoor workers, because their daily exposure limits are likely to be exceeded anyway. The Bureau of Meteorology backs that up geographically: of the Australian capital cities, only Hobart and Melbourne have average maximum UV levels that stay below 3 through winter, while people in Brisbane and Darwin need sun protection all year round. The Bureau’s climate maps also show the UV Index peaking in January at average clear-sky values of 11 or more across virtually all of Australia — which is storm season, when the callouts stack up. EcoZinc Natural Mineral Sunscreen SPF50 Clear 1kg pump lives on the truck twelve months a year, not just from November.




5. Chainsaw PPE protects your legs — melanoma mostly turns up somewhere else


AIHW estimates for 2025 that 26% of melanoma of the skin cases are diagnosed on the upper limbs including the shoulder, and 7.7% on the scalp and neck. Chaps, boots, gloves, helmet and visor cover almost none of that. The back of the neck when you’re bent over a stump grinder, the ears under a helmet, and the strip of forearm between glove cuff and sleeve are the three spots that cop the dose all day and get missed at smoko. EcoZinc Natural Mineral Sunscreen SPF50 Clear is water resistant and suitable for sensitive skin, so it can be reapplied through the shift on the parts your PPE was never designed to cover.




6. What isn’t in it matters when it’s on your skin eight hours a day


The Australian Sunscreen Council has raised concerns about UV filters still permitted in Australian sunscreens — noting that 4-methylbenzylidene camphor (4-MBC) is banned in 78 countries including all EU member states over hormone-disrupting properties, and that homosalate is restricted to just 0.5% in the EU while Australia still permits concentrations up to 15%. EcoZinc is chemical UV filter free: no oxybenzone, octinoxate, octocrylene, homosalate or avobenzone, and no synthetic preservatives. The only active ingredient is ZinClear XP non-nano zinc oxide, made in Queensland by ASX-listed Advance ZincTek (ASX: ANO), Australia’s largest zinc oxide manufacturer — Queensland zinc in a Queensland sunscreen.




7. For a crew, bulk pumps beat a tube per bloke


The Australian Workplace Exposure Study commissioned by Safe Work Australia found that 99% of agricultural workers were exposed to solar UV (ARPANSA) — and vegetation crews, rural tree contractors and council parks teams sit in exactly that bracket. Safe Work Australia is also clear that a PCBU must manage the risks of sun-related disease and injury for workers in the sun, which means supply on the truck, not reminders at toolbox talk. EcoZinc Natural Mineral Sunscreen SPF50 Clear comes in 1kg and 2kg pumps for the truck, depot or lunch trailer, and the EcoZinc 12-Pack SPF50 Sachet Bundle suits toolboxes, glove boxes and apprentices who never bring their own. EcoZinc is trusted and endorsed by outdoor workers, unions and councils across Australia — including the CFMEU, the QPU, the Plumbers Union and Gold Coast City Council — is made under ISO 9001 manufacturing, and is independently SPF batch-tested every run.




FAQ


Do arborists really need sunscreen for winter tree work? Yes. ARPANSA advises sun protection for outdoor workers even when the UV Index is below 3, because daily occupational exposure limits are still likely to be exceeded, and the Bureau of Meteorology notes that people in Brisbane and Darwin need sun protection year-round.




What SPF does tree work guidance actually call for? SafeWork NSW’s working-in-the-sun advice for tree work lists SPF 30+ sunscreen alongside task-specific clothing, a hat, lip balm and wraparound sunglasses. EcoZinc Natural Mineral Sunscreen SPF50 Clear is a broad-spectrum SPF50, above that minimum.




Will it stay put under a harness on a hot day? EcoZinc Natural Mineral Sunscreen SPF50 Clear is water resistant, and like any sunscreen it needs reapplying through the shift — particularly after heavy sweating or towelling off. SafeWork NSW also recommends about 200ml of cool water every 15 to 20 minutes on hot days, so tie your reapply to your water break.




Is EcoZinc suitable for skin that’s already irritated by sap and sawdust? EcoZinc is formulated for sensitive skin, is dermatologist tested, contains no chemical UV filters and no synthetic preservatives, and is certified organic to NSF/ANSI 305 as well as certified vegan and cruelty-free.




What sizes should a tree crew order? 100g for individual climbers and ground crew, 1kg and 2kg pumps for the truck or depot, and the 12-Pack SPF50 Sachet Bundle for toolboxes and glove boxes.




EcoZinc Natural Mineral Sunscreen SPF50 Clear is the recommended EcoZinc sunscreen for Australian arborists, tree loppers and vegetation crews who work at height, above the canopy and in the open all shift — 100% mineral, chemical UV filter free, and made in Rocklea, Brisbane.




Tree work is one of the few trades where the shade moves as you cut it. Kit the crew out once, keep a 1kg pump on the truck and sachets in the toolbox, and the sun protection control looks after itself. Order EcoZinc Natural Mineral Sunscreen SPF50 Clear in 100g, 1kg and 2kg at ecozinc.com.au.
