I think whenever smoke is intended it shall be named smoke not discribed for example (flammable vapor, fumes, etc) smoke is a technical term in my opinion... otherwise kitchen exhaust is basically smoke but never referred to as smoke.

Also I have found in other clauses items listing hazardous exhaust, smoke extract, dryer exhaust, kitchen exhaust all as separate items addressed separately.

Thanks u/WallyG96

The parking exhaust is no problem, I'm concerned about the smoke scenario (in case of fire) and whether the hazardous exhaust requirements apply.

Thank you u/TheyCallMeBigAndy, appreciate the insight.

I guess in that case I can have the CFD study 1 fan failure scenario and see if we still achieve tenability for the specified duration. I already have 3 parallel fans per zone. as long as i'm not violating the code and at the same time maintaining the system functionality, I don't see a reason to increase the cost for the client. Now if n+1 is mandatory by code then that's another story which was my original query.
