The Occupational Safety and Health Standards was formulated in 1978 in compliance with the constitutional mandate to safeguard the worker’s social and economic well-being as well as his physical safety and health. Adopted through the tested democratic machinery of tripartism, the 1978 Standards is considered as a landmark in Philippine labor and social legislation.

​

With joint efforts from the Bureau of Working Conditions, the International Labour Organization (ILO) Manila Office and the tripartite sectors, the revisions to the OSH Standards were approved in August 1989. With the latest improvements in the Standards, all establishments covered will now be provided with a better tool for promoting and maintaining a safe and conducive working environment.
