Outdoor Worker Skin Cancer Risk Assessment

People who work outdoors receive several times more annual UV than indoor workers, and the dose accumulates across every season of a career. This assessment profiles occupational exposure specifically — industry, years worked, hours in peak UV, the protection your workplace provides and how your own skin responds.

Quick answer

Outdoor workers typically receive two to three times the annual UV dose of indoor workers, and occupational solar UV is recognised internationally as a workplace carcinogen linked mainly to basal and squamous cell carcinoma, with melanoma risk also raised in some settings. The biggest modifiable factors are working through 10am–4pm without shade, missing sun PPE, and inconsistent sunscreen use.

This questionnaire assesses personal and environmental risk factors such as family history, UV exposure and skin characteristics. It does not analyse photographs and cannot tell you whether an individual mole is cancerous.

1.Which best describes your work?
2.How many years have you worked mainly outdoors?
3.On a typical working day, how many hours are you in direct sun?
4.Do you regularly work through the peak UV window (10am–4pm)?
5.Do you work in a high-UV climate or at altitude / on reflective surfaces (water, snow, concrete)?
6.Do you work outdoors year-round rather than seasonally?
7.Does your employer provide sun PPE (wide-brim hat, long sleeves, UV eyewear)?
8.Do you apply SPF 30+ on working days and reapply?
9.Has your workplace ever provided sun-safety training or skin checks?
10.How does your skin react to strong sun?
11.How often do you get burnt at work in a typical summer?

What your result means

Occupational exposure differs from holiday exposure in shape: it is chronic, daily and concentrated on the face, ears, neck, forearms and hands. That pattern is most strongly associated with squamous and basal cell carcinoma and with actinic keratoses — the rough, scaly precancerous patches that often appear on the scalp, ears and backs of the hands years before anything else.

The workplace-protection domain is the one an employer controls. Shade at breaks, scheduling heavy work outside peak UV, providing wide-brim hats, long sleeves and sunscreen, and running periodic skin-awareness sessions all reduce dose without reducing output.

What this assessment cannot tell you

It cannot diagnose anything, it cannot tell you whether a particular mole or lesion is cancerous, and it cannot replace an in-person skin examination. Risk-factor profiling and lesion assessment are two separate questions — a low factor load never rules out a suspicious spot, and a high one never means a spot is malignant.

If you have a spot you are worried about, use the AI mole checker for a photo-based assessment, and see a GP or dermatologist for anything that is changing, bleeding or failing to heal.

Occupational UV risk factors explained

Which trades take the highest dose

Construction and roadwork, agriculture and landscaping, utilities and telecoms, maritime work and grounds maintenance top most exposure studies, because the work is year-round, midday and often on reflective surfaces — water, concrete, sand and snow all bounce additional UV upward onto the face and under the chin, where sunscreen is usually missed.

Years matter more than any single summer

A decade of outdoor shifts represents a far larger total dose than a lifetime of beach holidays. This is why long-serving outdoor workers often present with multiple actinic keratoses rather than a single suspicious mole.

What to watch for on the job

Rough scaly patches that keep coming back, a pearly or shiny bump on the nose or ear, a sore that scabs and reopens for more than a month, and any mole changing in size, colour or shape. Anything in that list should be reviewed — start with a photo assessment using the AI mole checker and see a GP for persistent lesions.

For employers

Sun exposure is a controllable occupational hazard. ScanSkinAI runs workplace skin screening programmes for outdoor teams, with sector guides for construction and agriculture.

Frequently asked questions

Are outdoor workers really at higher risk of skin cancer?

Yes. Outdoor workers receive roughly two to three times the annual solar UV dose of indoor workers, and occupational solar UV exposure is recognised internationally as a cause of non-melanoma skin cancer.

Which skin cancers are most common in outdoor workers?

Basal cell carcinoma and squamous cell carcinoma, along with actinic keratoses, because these follow chronic cumulative exposure on the face, ears, neck and hands. Melanoma also occurs and should not be discounted.

Does a high-vis shirt protect me?

Standard workwear helps but varies. Tightly woven, long-sleeved fabric and a wide-brim hat give far more protection than a cap and a t-shirt, which leave the ears, neck and forearms exposed.

Should employers provide sunscreen?

Many occupational health guidelines recommend that employers provide sun protection alongside training and shade for outdoor work. Provision plus training is more effective than provision alone.

Can this assessment check a spot on my skin?

No. It profiles your occupational exposure only. For a specific lesion, use the photo-based mole checker and see a clinician for anything that persists.
