Ultraviolet radiation (UVR) is an occupational hazard for outdoor workers.This descriptive study aimed to describe the solar UVR risk, and explore associations between demographic characteristics and sun-safety knowledge, risks and practices, in golf-course maintenance workers on the island of Ireland.A survey, designed to collect demographic and occupational information, measures of skin cancer knowledge and sun protection practices, was completed by 154 male outdoor workers in the golf-course maintenance industry. Statistical analysis included tests of association and non-parametric tests.Less than 10% of this mainly male worker group had received education/training on solar UVR risks (sun safety) and two-thirds were more concerned about workplace injury. While a majority used routine precautionary measures, those with greater knowledge of skin cancer, senior grades and workers under 45 years were significantly more likely to use sunscreen and/or sunglasses.Findings indicate that these workers were a high risk group for skin cancer, with good knowledge of the risk, but limited training or education in risk reduction. While the prevalence of sunscreen and sunglasses use is relatively good, it was better among younger workers and those in senior grades, and could be improved if they were routinely provided as a control measure by the employer.
