The previous posts were all about fire and dust. I wanted to post an example of a flash fire caused by a dust cloud.
This fireball was created with less than 1 teaspoon of dust. Imagine the size of the fire if hundreds of pounds of dust were ignited. Many of the deaths resulting from dust incidents are due to the burns from the flash fire not from injuries caused by an explosion. The happens so quickly there is no way to get out of the way of the flames. You will be suddenly engulfed in flame.
The purpose of the Dust Hazard Analysis (DHA) is to examine your facility and processes so that risks that can lead to flash fires are managed and controlled.
