typically I see designs that require garage exhaust to be taken not higher than 18" above floor. I believe the reasoning is CO is lighter and with such low intake of the exhaust air we capture CO better. I wanted to verify the exact requirement, but can't find a code that details the 18"? I only found it referenced for fuel dispensing facilities in IMC 502.1.2, which is not my case. Many people tell me about the 18", but no one can show me the code.
some questions I have are:
- do diesel garages have the same requirement (they produce more soot and NOx than CO)
- assuming the 18" requirement is real, how are angled intakes treated? To increase the screened area, we typically have 45° sloped intakes. teh back (at wall being lower, the front being higher. now which do we measure to satisfy the 18"requirement?
