Articles

The articles featured here, by Dr. David Leggett, describe a variety of hazard identification techniques. They include a series of papers that present straightforward methods to highlight the hazard potential of small scale operations. These techniques take only a couple of hours to perform.

Tianjin Chemical Warehouse Explosions – Never Let A Serious Crisis Go To Waste

Tianjin Chemical Warehouse Explosion - Never Let A Serious Crisis Go To WasteWarehousing hazardous chemicals, on a large scale, is not uncommon, and can be done safely provided the facility is properly designed. The Tianjin explosion (August 12, 2015) highlights the...
