The prevalence of accidents in the construction industry is declining, but not enough. Each year around 2.9 per cent of construction workers are injured; however, this figure rises to 4.1 per cent for workers at the frontline (skilled and building trades). Of these, 25 per cent result in serious injury (requiring more than seven days off work). The cause of most fatal injuries is falls from height. Non-fatal injuries are spread amongst slips and trips, carrying objects, falls from height and being struck by moving or falling objects. In occupational health terms, 65 per cent of injuries/illnesses are accounted for by musculoskeletal conditions and respiratory diseases; 15 per cent are stress related.
