Tradies may have to add another hazard to their list of job-associated dangers after a Perth man was burned by his high-vis vest.

The 40-year-old noticed the painful red rash across his back after he undressed from working outside on a hot day as a field environmental engineer, according to a letter to the Medical Journal of Australia.

ED staff found he was well but had a non-blanching, band-shaped erythematous rash across his upper back with no associated vesicles, consistent with a first-degree burn.

“It was noticed that the band-shaped rash coincided with the upper high-visibility band on his work shirt,” wrote the author, emergency specialist Dr Ioana Vlad, from Sir Charles Gardiner Hospital in Perth.
