IMC Section 510
I was wondering if anybody had any experience complying with IMC Section 510. Essentially I have a room that will be used for gluing (by means of a glue gun). I am installing hoods connected to an exhaust fan and a make-up air unit to match.
In order to avoid having to install a hazardous exhaust system, I need to prove that I can avoid one condition which is: "A vapor, gas, fume, mist or dust with a health-hazard rating of 1, 2, or 3 is present in concentrations exceeding 1 percent of the median lethal concentration of the substance for acute inhalation toxicity."
I know my median lethal concentration for the glue, I know my exhaust and ventilation rate, and I can find out what the volumetric rate of the glue gun. How would you guys recommend going about calculating the amount of glue vapor/substance is present when all three components are in operation (exhaust, make-up, and glue gun)?
Thanks for any and all help!

At the steady state you will exhaust glue vapors at the same rate as they are being produced (P):
V x C = P
where V is the volume exhausted (e.g. cfm) and C is the concentration of glue in the air.
The steady state concentration of glue will therefore be:
