All-Round Safety. Around the Clock.
Standards Brief: IEC 61511 Edition 2
Processing plants are becoming more complex and legal requirements are changing. Therefore, the international safety standard IEC 61511 for the functional safety of processing plants has recently been revised and released in its second edition. What's important for you is that ANSI/ISA 84, the US equivalent of IEC 61511, will be soon updated based on the changes introduced in IEC 61511 Edition 2. This might have implications for your HIMA safety systems. They could require modifications, tests, and checks, and you may have to alter the way you operate your systems.
