As the process sector moved into the computer age, new issues arose as manufacturing plants converted to computer control to replace electrical, pneumatic, and electronic controls. The process sector is faced with many plant floor factors that require additional risk reduction analyses, such as security, wireless instrumentation, alarms, human factors, BPCS, and many other protection layer issues.

Safety life cycle The ISA84 committee set out to define the boundaries of its work by developing a safety instrumented system SIS safety life cycle see Figure 1which illustrated the activities involved when addressing process sector functional safety.

For existing SIS, the costs to comply will consist of engineering cost and, in most cases, hardware cost. Tomorrow IEC 2nd edition and future: I would not have been able to keep going to school if I had not received it.

In many cases, at older sites, additional design and equipment will be required to allow online testing. So, I want to give thanks to the many people of the ISA who ajsi on securing the future of the organization just as the original founders had.
