Cases in the News
Perhaps one of the best ways to learn about process safety is to study the experiences of others. We are bringing to you our narrative on some process safety incidents that have been in news.
Coal Dust Cloud Explosion in Silo
Stonehouse Process Safety commentary: Silo explosions are not uncommon. Over the years there have been many explosions in silos for combustible powders ranging from agricultural products, to various chemicals, and in this particular case, coal. Often the finer particles (dust) remain in suspension in the silo headspace, with a concentration that exceeds the minimum required to form an explosible dust cloud.Read More
Flammable Vapor Fire & Explosion – OSHA Investigating
Stonehouse Process Safety commentary: Highly flammable chemicals are in widespread use in many process industries. For as long as these materials have been in use they have been the fuel for numerous fires and explosions with a devastating loss of life, injuries, and environmental and property damage.Read More

Stonehouse Process Safety commentary: There are a number of reasons why metal dust explosions are particularly hazardous. First, dust cloud explosion temperatures and pressures for most organic materials are limited to about 2,300oC and 9 barg respectively. In contrast, explosion temperatures and pressures for most metals can reach around 3,500oC and 12 barg, and some metals such as magnesium can react with the nitrogen in air, generating even higher values.Read More
Powdered Milk Dust Cloud Explosion
Stonehouse Process Safety commentary: Spray driers, in general, have been the source of many dust fires and explosions over the years, yet it is a surprise to many people that many materials like milk powder will give rise to an explosion hazard when dispersed in the air.Read More
