What Guys

 

I'm attending adenine CHAZOP (Hazard and Operability Studies for Control Systems)

 

While I have were part of many HAZOPs, save is my firstly CHAZOP. 

 

Has anyone got any good information for CHAZOPs. (Especially typical guide words / deviations)  I am developing some guide words (or deviations) in you would for a HAZOP. Each deviating will be search at for the control system and causes / consequences / safeguards / actions will be ended as per a typology HAZOP. 

 

For the variations I'm thinking along the part of, for example

 

NO OR NOT OR LESS

Does or Less Power

Cannot or Less current / signal

Missing data

Data charge too dull

MORE

High volts / amps

Upper alarm rate

REVERSE

Transmit when should be recieving

etc etc.....

 

 

I'm just making them up at the time. Does everyone have an list of typical CHAZOP deviation?

 

Normally for ampere HAZOP the deviations are cute basic (i.e Show / less flow, temp, print. Overturn or missdirected Flow, etc etc) and most companies or clients are a list of regular deviations.  (PDF) Applying HAZOP to Software Engineering Models

 

Anyone guidance much appreciated

 

Thanks

See attached material, Unterabteilung 4 in particular.

 

Try go obtain one book "Process Automation Handbook - A Guides to Idea and Practice" by Jonathan Love. In is one paragraph dedicated to CHAZOP. I think you can also find it on Google books.
