OSH-Standards-2020-Edition.Pdf OCCUPATIONAL SAFETY AND HEALTH STANDARDS (As Amended, 1989) Department of Labor and Employment Philippines Reprinted with permission from the BUREAU OF WORKING CONDITIONS DEPARTMENT OF LABOR AND EMPLOYMENT Intramuros, Manila Published and printed by the OCCUPATIONAL SAFETY AND HEALTH CENTER DEPARTMENT OF LABOR AND EMPLOYMENT North Avenue corner Agham Road, Diliman, Quezon City February 2005-May 2019 FOREWORD 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. The advent of industrialization and the continuing introduction of technological innovations in our country today have, however, correspondingly increased the number and types of occupational hazards that our workers are exposed to. Viewed against this backdrop, it became imperative that the Standards be revised to make it truly responsive to the workers’ needs. Joint efforts exerted by the Bureau of Working Conditions, the ILO Manila Office and the tripartite sectors bore fruit in August 1989 when the revisions were finally approved by the Secretary of Labor and Employment pursuant to his authority under Article 162 of the Labor Code of the Philippines. 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. I therefore urge all sectors concerned-whether they be in labor, management, government or the academe-to extend their full support to achieve the noble objectives of the Occupational Safety and Health Standards.

  • Did You Know? Hazards of Relief Devices in Series What Can You
    Sponsored by http: //www.aiche.org/ccps/safetybeacon.htm CCPS Messages for Manufacturing Personnel Supporters Hazards of Relief Devices in Series November 2006 A vessel has a rupture disk and a pressure relief valve in series to protect against high pressure in the vessel. There is a pressure gage on the pipe between the rupture disk and the relief valve. As a part of your regular plant inspection, you are supposed to check the pressure gage. The gage normally reads Rupture zero. Today you observe a pressure of nearly 50 psig (~3.5 barg) as shown. Disk Do you understand why this is a significant hazard? How does pressure between the rupture disk and the pressure relief valve affect the performance of the vessel overpressure protection system? Pressure Relief Valve Did you know? What can you do? A rupture disk bursts when the pressure on the process Check to ensure that your training side of the disk exceeds the pressure on the downstream program covers this situation. side by the design pressure of the rupture disk. So, a 100 Do you know what to look for to psi (6.9 bar) rupture disk will burst when the pressure on recognize a rupture disk and relief valve the process side of the disk is 100 psi (6.9 bar) greater in series? than the pressure downstream of the disk.
