Traditional occupational safety methods are analysis of accidents and accident statistics, regulations, standards and safety guidelines. The most significant standards used for occupational safety are the British BSI (1996,1999) and the international standard by ILO (2001). In addition various analyses of occupational accidents have been published, examining causes of injuries and fatalities such as those performed for the construction sector by Ale et al (2008), for the electric power industry by Carnero and Pedregal (2010) and for the extractive industry by Silva and Jacinto (2012).
