The Aerosol Laboratory: Safety Check - Ignition Source
By: John Chadwick
I have been wandering around the aerosol industry for the last 35+ years both as an employee of major CPG companies, and, for the past 15 years as an independent aerosol technical consultant. While the attention to safety issues has dramatically improved over time, I am still amazed how often the simplest safety precautions are sometimes overlooked when filling aerosols with flammable propellants. I'll save my horror stories for another time, except for one particularly relevant example at the end of this article.
