Occupational health and safety

Occupational health and safety represents an important issue for the society since industrial revolution when, in response to the public concern with regards to the work conditions for women and children working in cotton manufacturing, the first measures to regulate working hours and define minimal health and safety requirements for employees were established in Britain.
Things evolved later in the 20th century and occupational health and safety has become a well established concept worldwide through the involvement of organizations like the WHO (World Health Organization) and ILO (International Labour Organization).

OHSAS 18001 Standard

First edition of OHSAS 18001 has been published in 1999 and back then there were many standards and certification schemes creating confusion and fragmentation on the market. Accepting this British standard at international level facilitated the adoption of a common language in the field of occupational health and safety.
In 2007, OHSAS 18001 has been revised, especially to make it more compatible with ISO 9001 and ISO 14001 thus facilitating the implementation and audit of an integrated management system.

OHSAS 18001 has been developed outside the International Standards Organization (ISO). Presently  ISO is in process of developing its own standard (ISO 45001) to define the requirements for an occupational health and safety management system. The publication of ISO 45001 is expected in 2018.

OHSAS 18001 Certification

The main elements of OHSAS 18001 include the identification of health and safety hazards, the risk assessment and the implementation of controls to prevent work related accidents and professional illness.

OHSAS 18001 can be implemented and certified individually or integrated with other management system standards like ISO 9001 and/ or ISO 14001.
