SS 651:2019 is the newly developed Singapore Standards for Safety and Health (S&H) for chemical industry and reference from ISO 45001:2018. SS 506: Part 3: 2009 was formerly used as the Singapore Standards for Occupational Health & Safety (OH&S) which was derived from the former benchmarked OHSAS 18001.

Decision making shall also involved consultation and participation of workers in the process safety incidents.

Risk and Opportunities
