Things to Know About Gas Masks

The gas mask is working for me. I used the third-floor conference area of a Germantown-based company for "health and personal security" to strap one on. Then I cut up an onion raw with paring knives. I didn't cry even though the bulb was causing a chemical reaction in my eyes.
