The ISO 45001 certification is the new version of the 1999 OHSAS 18001, which was revised later in 2007 (OHSAS: Occupational health and safety management systems). It provides indications on how to make workplaces safer for companies and organizations. A safe workplace reduces the risk of accidents and it decreases the possibility of contracting occupational diseases. Making the workplace safe is an employer’s duty, but it’s also a cost saving source due to potential accidents or illness. In the event of an accident, for example, the employee it’s more expensive five times as much to the enterprise (among overtime, any strikes, investigations, etc.).
