From AIChE=E2=80™s Center for Chemical Process Safety, the "Process Safety Beacons" for the last few months:
Mechanical Integrity - "You get what you inspect, not what you expect!"
Conduct of Operations - "What are your plant's critical safety control limits?"
Know When to Leave! - "Know what can go wrong in your plant, when you should evacuate, and when to shelter in place!"
Operational Readiness - "Any time that you introduce material or energy into equipment that is not currently being used, it is essential that you confirm that the equipment is ready. Are all of the parts of the equipment actually there and properly installed, or is something missing? Are all the valves that are supposed to be open actually open, and all the valves that are supposed to be closed actually closed? Is everything else ready to use?"
