Thoughts on Prescriptive Design – It Doesn’t Solve Everything, and Sometimes Doesn’t Solve Anything
Some Organization’s feel they can address the requirements of the Safety Lifecycle by developing prescriptive requirements. This can be effective in enforcing some level of conformance with Safety Lifecycle requirements, but it can also have the opposite affect if not done properly.
1.) Are the prescriptive requirements complete?
Compliance with the Safety Lifecycle is far more than a...
The Biggest Problem with Safety Lifecycle Management Roles and How You Can Fix It
Many organizations are trying to figure out how to manage the Safety Lifecycle. Leadership will often end up just appointing someone as “the SIS guy”. Sometimes the role is given a fancy title, but the intent is to assign the issue of the entire Safety Lifecycle to someone. That someone is usually in engineering,...
Two Major Issues with Managing Safety Lifecycle Data
There are many issues with managing Safety Lifecycle data in a real plant environment. The fundamental problem is that the tools available in the plant are traditional and unsuitable for an effective Safety Lifecycle Management program. Especially for Instrumented Systems, much less other functions such as non-instrumented systems or relief systems.
Plants that manage...
Benefits of Effective Bypass Management
SA-TR84.01.00 and IEC 61511 ed 2, Part 1, contain extensive discussions of the design and operating procedures for Safety Instrumented Function (SIF) bypasses. Clause 16.2 describes operational requirements such as:
- Performing a hazard analysis prior to initiating a bypass
- Having operational procedures in place for when a protective function has been bypassed ...
What Went Wrong With The Process Safety System? Lessons From The 737 Max Crash
When there is a major accident somewhere, you have to investigate what errors might have been made that contribute to it. Boeing’s problem with the 737 Max crash highlights a few fundamental issues with the process safety system that need to be examined.
4 Lessons Learned:
Issues With Managing Process Hazard Analysis (PHA) Data
National and local regulations require that all process operations have a formal Hazards Analysis performed on the original installation as well as for all modifications to the facility. Most regulations also require that the Process Hazard Analysis (PHA) of record be re-validated at regular intervals, such as the 5-year re validation cycle required in the US.
PHA is a...
