General Comments - Aerosols

Aerosol technology encompasses two primary scientific disciplines. The first is Physical Chemistry and the second is Material Science (more specifically, metallurgy, corrosion and failure analysis).

 failures of aerosol products often lead to fires (due to the flammable propellants propane and butane)
Physical Chemistry deals with the product in the aerosol can (the substance for which the aerosol was purchased). The product is most often a liquid solution or emulsion, both of which are within the curriculum of Physical Chemistry. The propellant for aerosols (the substance that gives it spraying power) is most often a liquefied gas or a compressed gas, both of which are within the course work of Physical Chemistry.  The most common propellants are propane and butane, both of which are highly flammable.

The aerosol containers are most often made from metal (steel or aluminum) and the failure of a metal container is the topic of Material Science or Metallurgy, Corrosion and Failure Analysis.

The Founder of Chemaxx, Dr. Fox has exceptional strengths in both of the scientific disciplines that encompass aerosols. He has his Ph.D. in Physical Chemistry and has spent over half of his professional career in Metallurgy, Corrosion and Failure Analysis. He is recognized on an International level in metallurgy. He is also accredited in Basic Corrosion and Cathodic Protection by the National Association of Corrosion Engineers and accredited in Failure Analysis and Metallurgy by ASM.  Dr. Fox has experimentally investigated aerosols for more than 12 years using over 25 different methods and is the first scientist to author a peer-reviewed paper on the explosive failure of aerosol containers. As of February 2013, Dr. Fox has 6 peer-reviewed scientific publications on the failure analysis of aerosols, plus 2 invited papers on aerosol technology. Dr. Fox's 2007 paper in the ASM Journal of Failure Analysis & Prevention was given the Paper-of-the-Year Award.

Dr. Fox is accredited in Aerosol Technology by the Center for Professional Advancement and has completed the Aerosol Technology Course offered by the British Aerosol Manufacturers Association. He is also Certified by the DOT in the transportation of hazardous materials (the DOT regulates aerosol containers and the products that can go in them).

Finally, since failures of aerosol products often lead to fires (due to the flammable propellants propane and butane), it should not go unnoticed that Dr. Fox is a Certified Fire & Explosion Investigator who is also an aerosol expert. He made presentations at national societies on the fire and explosion hazards associated with aerosols and was the first to publish a peer-reviewed paper on aerosol failures. He now leads the field in the number of peer-reviewed papers on aerosol failures. For further details on Dr. Fox's qualifications as an aerosol expert witness click here.
