A high-vis shirt, a hard hat and a hot day can create a false sense of security. Ultraviolet (UV) radiation cannot be seen or felt, yet exposure accumulates across ordinary working days. Effective workplace sun safety protects people who work outdoors and those exposed near windows, on roads, around water or in reflective environments. In Australia, where UV levels can remain damaging even when the temperature is mild, prevention needs to be part of how work is planned – not an optional extra.

Skin cancer is one of Australia’s most common cancers. Much of the risk is preventable, but prevention only works when employers and workers act before sun damage occurs. Every minute counts when a suspicious spot is noticed, but reducing avoidable UV exposure is the first line of defence.

Why workplace sun safety needs more than sunscreen

Sunscreen matters, but it cannot carry an entire sun-protection plan. It can be missed, applied too thinly, washed or rubbed off, and forgotten during busy shifts. Workers may also be reluctant to reapply it when there is no access to clean hands, shade, breaks or supplies.

The strongest approach follows the same principle used for other workplace hazards: control the risk through the way work is designed. This is especially relevant for construction crews, farmers, gardeners, delivery drivers, council teams, roofers, fishers, surveyors, sports staff and anyone spending significant time outside.

UV exposure is not limited to cloudless summer days. In much of Australia, UV levels can be high from early morning through late afternoon. Clouds do not reliably block UV, and reflection from water, sand, concrete, metal roofs and pale surfaces can increase exposure to the face, ears, neck and lower legs. A cool, overcast day may still carry a high UV risk.

Outdoor work is not the only concern. People who drive for work can receive substantial UV exposure through side windows, particularly on the side of the body closest to the window. Office staff working beside large windows may also be exposed over time. The level of risk depends on the glass, the duration of exposure and the position of the workstation, but it should not be dismissed simply because the work is indoors.

Workplace sun safety starts with planning

Employers have a responsibility to provide a safe workplace and manage foreseeable health risks. UV radiation is a recognised occupational hazard for outdoor workers. A written sun-protection policy gives supervisors and workers a clear standard, particularly when workloads are high or conditions change.

Start by identifying when, where and who is most exposed. Consider the time of year, local UV forecasts, the hours spent outdoors, reflective surfaces, access to shade, and whether workers can take breaks without falling behind. Casual staff, apprentices and contractors need the same protection as permanent employees.

Where practical, schedule physically demanding outdoor tasks outside peak UV periods. This will not always be possible, particularly in emergency services, agriculture or construction. When timing cannot change, the focus should shift to shade, protective clothing, task rotation and reliable personal protective equipment.

Shade is one of the most useful controls. Fixed awnings, covered workstations, shade sails and temporary marquees can protect workers undertaking repeated tasks in one location. For mobile crews, a portable canopy or a shaded vehicle break area can make a meaningful difference. Shade should be available where workers wait, eat, complete paperwork or prepare equipment, not only at the work site itself.

Protective clothing should be fit for the job

Workwear needs to protect skin without creating unacceptable heat stress or interfering with safety requirements. Lightweight, closely woven long-sleeved shirts and long trousers offer better coverage than singlets and shorts. A collar that covers the neck is particularly valuable for workers who spend hours looking down, driving or operating machinery.

Broad-brimmed, bucket or legionnaire-style hats offer better protection than caps, which leave the ears and neck exposed. Hard hats can be fitted with brim attachments or neck flaps where appropriate, provided they meet workplace safety requirements. Wrap-around sunglasses that meet the relevant Australian standard can help protect the eyes and surrounding skin.

There are trade-offs. Extra clothing can feel uncomfortable in extreme heat, and some equipment may not be suitable around moving machinery, fire hazards or particular chemicals. This is why sun safety should be planned alongside heat management, hydration, ventilation and task-specific PPE requirements rather than treated as a separate issue.

Make sunscreen accessible, not symbolic

Broad-spectrum, water-resistant SPF 50 or SPF 50+ sunscreen should be available at no cost to workers whose duties expose them to UV. It should be easy to find, within expiry date and stored away from excessive heat. A forgotten bottle in the ute is not a dependable workplace control.

Workers should apply sunscreen to clean, dry skin 20 minutes before going outdoors, then reapply at least every two hours and after heavy sweating, swimming or towel drying. It should cover exposed areas including the face, ears, neck, backs of hands and lower legs where relevant. Lip balm with SPF can be useful for outdoor workers, particularly smokers and people with frequent sun exposure, as lip cancers can occur.

Sunscreen is a backup to clothing, shade and sensible scheduling, not permission to remain unprotected in direct sun for longer. This distinction helps avoid a common and dangerous misunderstanding.

Build a culture where protection is normal

A sun-safe policy fails if workers feel that hats look unprofessional, long sleeves are inconvenient or breaks are a sign of poor productivity. Leaders set the tone. Supervisors who wear protective clothing, use shade and make time for reapplication demonstrate that safety is part of the job.

Brief UV reminders can be included in pre-start meetings, particularly before summer, during long outdoor projects or when new staff arrive. Keep the message practical: check the UV level, wear the required clothing, use sunscreen, take shaded breaks and report damaged shade structures or empty sunscreen dispensers.

Workers should also be encouraged to speak up if their PPE is unsuitable. A one-size-fits-all approach can exclude people who need different sizing, modest clothing options, prescription safety sunglasses or adjustments for cultural and medical needs. Good sun safety is workable sun safety.

Know when sun damage needs a skin check

Prevention reduces risk, but it does not erase past exposure. Outdoor workers and people with a history of frequent sunburn should be alert to new or changing spots. This includes a mole that changes in size, shape, colour or sensation; a sore that does not heal; a scaly patch; a pearly or shiny lump; or a spot that bleeds, crusts or becomes tender.

Not every concerning lesion is skin cancer, and skin cancers do not all look the same. Melanoma can appear as a changing pigmented spot, but it may also be pink, red or skin-coloured. Non-melanoma skin cancers can look like persistent rough patches, ulcers or raised lesions. Skin cancer can affect people of every skin tone, including areas that receive less sun exposure.

Workers should not wait for a workplace medical to mention a worrying spot. Arrange a prompt skin check with a qualified clinician if a lesion is new, changing or not healing. People with a personal or family history of skin cancer, many moles, a weakened immune system or years of high occupational sun exposure may need more regular clinical advice.

A practical standard worth protecting

Workplace sun safety is not about blaming workers for exposure they cannot avoid. It is about giving them realistic protection through better planning, suitable equipment and a workplace culture that takes UV seriously. The safest shift is one where shade, protective clothing and sunscreen are as routine as any other essential PPE.

A changing spot can wait for no roster, project deadline or next summer. Protect your skin at work, and seek a skin check promptly when something does not look right. Knowledge can save your life.
