Q1. Suppose that an industrial process produces the following air-contaminant concentrations for the periods shown:
Period Methanol(ppm) Nitric Oxide(ppm) Sulfur Dioxide8AM - 10 AM 50 5 010AM - 11 AM 150 10 111 AM -1 PM 100 5 11 PM -4 PM` 200 10 1
Taken collectively, would these concentrations exceed the OSHA permissible exposure limits? Explain
Q2. Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere. Would this help or hinder matters? Explain
