What's Happened Lately?
SAFETY -- NATIONAL EMPHASIS ON COMBUSTIBLE DUST [updated 2008-04-18]: Following a deadly explosion at a sugar refinery the Occupational Safety and Health Administration (OSHA) has issued a directive (CPL 03-00-006) initiating a National Emphasis Program (NEP) on Combustible Dust. OSHA offices are required to begin inspections of sites that handle combustible dusts, specifically targeting dust explosion hazards. If your facility handles such powders consider reading
See OSHA's Combustible Dust National Emphasis Program [PDF file]
Chilworth Technology posts articles and offers courses.

HOW SAFE IS YOUR PLANT?: The Center for Chemical Process Safety (CCPS) -- an AIChE-Technical Industry Alliance -- publishes and posts The Process Safety Beacon as a series of one-page bulletins (in several languages). These provide photos and a brief description of an industrial incident and discuss what can be done to avoid or minimize the damage from such incidents. On our Safety page we have added links to PDF files for eleven of these bulletins about specific problems for processes that involve particulate material.
AN ON-LINE CALCULATOR: Our page on Particle Characterization now has an online calculator for the area, volume, and mass of single particles of various shapes. It also computes the area per gram of particles and the number of particles per milligram. This is useful for illustrating how dramatically the area per gram increases as particle size drops and how a change from compact to extended shape increases the surface area.
IN SEARCH OF AUTHORS: Have you prepared educational material in on some topic in Particle Technology? If so you may wish to consider publishing it in ERPT. See our guidelines for authors, read some of our articles, and then drop a note to the Managing Editor at erptmged@aol.com
WHAT IS ERPT? ERPT was launched in 1998 as a public education service of the Particle Technology Forum, a technical division of the American Institute of Chemical Engineers. This Web site provides on-line, just-in-time, world-wide, free-of-charge tutorials in particle technology as a public service. Our goal is to build a site that will eventually provide several hundred tutorials, each equivalent to one to three hours of classroom instruction at the third-year college level. These will be introductory in nature and in the ideal case will describe the main phenomenological and theoretical aspects of the topic, also noting industrial applications, large-scale equipment, typical industrial problems, and typical solutions to those problems.

ERPT provides
-- tutorials at the undergraduate and graduate level
-- ideas and examples for enriching classes and laboratories
-- typical solutions for common industrial problems
Professional oversight is provided by the Particle Technology Forum, a technical division of the American Institute of Chemical Engineers.
Web site design, editing, and maintainance is provided by
      Dr. Ralph D. Nelson, Jr., P.E., the Managing Editor of ERPT
