What is the context of this "project"?I am working on a little project and need some help.
Is it going to be physically realised, or is it just a paper exercise?
What is the physical environment? e.g. is the float switch in a car windscreen wash reservoir or a 10,000l vat of boiling triethylborane?
What are the consequences of undetected failures?
Who or what needs protecting from them?
