Outdoor workers’ health at risk from sun, study finds
By MARK HOTTON – Thursday, 26 February 2009
Outdoor workers are at risk of eye disease and skin cancer because of overexposure and under-protection in the sun, a University of Otago study has found.
The problem of high UV-radiation exposure was made worse with less than a third of the 77 workers in the study applying sunscreen and only 5 per cent wearing a wide-brim hat.
Unless adequately protected, all of them would have received more UV radiation than the recommended level of 1.
The workers in the study, conducted by postgraduate student Vanessa Hammond, included construction, horticultural and road workers employed at 14 Central Otago workplaces.
An exposure of about 1.08 SED (standard erythemal dose).0 SED could cause sunburn to someone with unprotected fair skin.5 to 3.3 SED between 11am and 4pm. The average daily summer exposure of the workers was 5.
Study co-author Dr Tony Reeder, director of the university's Cancer Society social and behavioural research unit, said employers had an important role in protecting their workers from the sun.
Hammond said any opportunity to work in the shade could make a real difference in reducing the risk of a worker developing skin cancer. .
Outdoor work between 11am and 4pm needed to be undertaken in either natural or constructed shade in summer, he said.
"It all sounds very nice but there'd be a big cost with it.
However, Amalgamated Builders health and safety manager David Baker, of Dunedin, said movable shade structures were impractical given the scale of building sites.
"You can provide but it's up to the guys to use the stuff," Baker said."
The company supplied personal protective equipment such as wide-brim clip-on hat options and sunscreen, but it was up to each employee whether they used it.
"I've just put a lid on [the tractor] for that reason.
Gore farmer Hamish Smith said he had taken steps to address his exposure to the sun. But it can just get too hot. There was always sunscreen in the tractor and that was used too.
Builder Barnaby Lamb, who was wearing a sleeveless top on a Queenstown building site yesterday, said sunscreen was supplied on site and he regularly applied it."
Work was started early to avoid the day's heat and a hat was essential.
