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.

A Viable Product vs. The Legal System

By: Dr. Carl J. Abraham

In the United States, the most litigious country in the world, a products liability action may be brought, under state law, for express or implied breach of warranty, misrepresentation and negligence. Under the theory of strict liability, a lawsuit may be initiated on the grounds of manufacturing and design defects as well as poor and inadequate warning instructions. The best defensive strategy for a company to avoid becoming involved in any of the above is to manufacture the safest product possible within parameters of economic feasibility. If said manufacturer can vouch for safety factors in the design, production, testing, inspection and evaluation of its product as well as attentiveness to consumer complaints, it will be more likely to avoid litigation or at least be able to prevail in the courtroom.
