Diffusion of integrated Occupational Health and Safety Management Systems

Some previous reported studies may be considered as references or benchmarks to the work intended to be developed regarding IMSs. The analysis of the geographic diffusion of the ISO 9001 issued certificates was targeted by the work of Sampaio et al. (2009, 2010), Sampaio & Saraiva (2011), Salgado & Sampaio (2013), Viadiu et al. (2006), Neumayer & Perkins (2005), Mangiarotti & Riillo (2010) and Franceschini et al. (2004). Concerning the geographic diffusion of ISO 14001 certificates one should point out the work developed by Casadesús et al. (2008), Marimon et al. (2011) and Peixe et al. (2012).
