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.
This series, "Aerosol Anatomy," will dissect and examine various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, and quality control.
This article continues the Aerosol Anatomy series, which dissects and examines various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, and quality control of aerosol products.
This is a continuation of the Aerosol Anatomy series, which focuses on dissecting and examining various technical topics in aerosol technology, including product development, new technology, components of the aerosol system, quality control and other related topics of interest to formulators and manufacturers of aerosol products.
One day, while doing his weightlifting routine on the exercise ball in the sauna, the exercise ball exploded, sending Leo onto the ground in an awkward position, with the 200 pound barbell landing on top of his shoulder. Leo’s shoulder was separated and required surgery to repair the damage.
A batch of 100 pound boxes of packaged seasoning mix produced was left in the processor's warehouse overnight and was found to be smoldering in the morning. The pallet of smoldering 100-pound poly-boxes of the seasoning blend was moved to just outside the building, whereupon it ignited and engulfed in flames the nearby outside stored drums of other food products, ultimately causing the building itself to catch fire. The entire building and its contents burned to the ground, causing loss exceeding $2 million dollars worth of product and total loss of the building.
Howard M. Kipen MD, MPH, is Board certified in Internal Medicine and Occupational Medicine. Dr. Kipen earned a BA from UC Berkeley, MD from UCSF, and MPH from Columbia University. He currently serves as Director of the Clinical Research and Occupational Medicine Division and Professor of Environmental and Occupational Health at Rutgers University. Dr. Kipen’s research focuses on clinical and epidemiological studies of the health effects of Indoor and Ambient Air Pollution. His research uses both controlled exposure models with ozone, fresh aerosols, and diesel-enriched on-road exposures, primarily with drives on the New Jersey Turnpike. A new EPA study examines health benefits of portable air cleaners for reducing indoor air pollution levels. Biomarker outcomes presently emphasized are exhaled breath oxidative stress and invasive and noninvasive measures of vascular function. Dr. Kipen has published morethan 200 articles on environmental / occupational health. Scholarly Activities:
Former Chair, NASA Human Research Program’s Advanced Environmental Health / Advanced Food Technology Standing Review Panel
Member, National Academies Standing Committee on Medical and Epidemiological Aspects of Air Pollution on U.S. Government Employees and their Families, 2016
Chair / Member Multiple Ad Hoc Grant Review Panels (e.g., NIEHS, Department of Defense)
Governor’s Appointee, Public Employee’s Occupational Safety and Health Review Commission, New Jersey Department of Labor
Member, Public Health Scientific Advisory Board, New Jersey Department of Environmental Protection
