Incidence rates were 2.0\/1000\u2009hours for acute mechanism injuries (95%\u2009CI 1.5 to 2.5) and 3.2\/1000\u2009hours for illnesses (95%\u2009CI 2.6 to 3.9). For acute mechanism injuries the head, shoulder and lumbosacral region had the highest injury burden of 5.6 (95% CI 4.8 to 6.5), 2.9 (95% CI 2.3 to 3.5) and 2.2 (95% CI 1.7 to 2.8)\u2009days of time loss\/1000 hours, respectively.
