The most immediate operational change is the adjustment of the direct cost damage thresholds for fires and explosions. In previous editions, the thresholds were set at $100,000 for Tier 1 events and $2,500 for Tier 2 events. The 4th Edition updates these direct cost figures to account for inflation ...

Are there any reference handbooks on process safety?
Recommend me some.
I have CCPS ones with me. Means some other than these, common issues, missed out, connecting with actual incidents etc.

Yeah, I used my existing credentials on the app, it worked.

As part of process safety metrics, safe operating limits excursions, everything is required to be reported, be it the flow, concentration etc.?

I am not sure if you have tried, "Materials Selection for Hydrocarbon and Chemical Plants" by David A. Hansen and Robert B. Puyear
This text provides a systematic, workflow-oriented approach tailored directly to process plants. It introduces a template-driven logic for material selection that ...

They can take each others responsibility by the nature of their basic qualifications and process experience? Yes as the basic studies would originate from understanding of chemical engineering. However, in actual when they are working in these different roles, they entirely have very different ...

Fluid flow, heat transfer and distillation may come under unit operations as they are physically derived parameters.
However, chemical reactors where there are chemical reactions would be considered as unit process.

Positions responsible to perform work and assess the condition of safety critical equipment should be the ones termed as HSE critical positions.
And yes, in principle, functions working in operation & maintenance by default would be categorized as those however, technical support functions providing ...

Notes from Norman's book;
"Hydrocarbon leaks in water cooling service can cause explosive mixtures to form below
the distribution decks in cooling towers. Especially when cooling butane streams, this
can, and has (Amoco Oil—Texas City), caused cooling towers to ignite. Check your cooling
