A methodology to evaluate industrial vapor and dust explosion hazards



A methodology was developed to evaluate the potential of vapor, dust and hybrid mixtures (combustible dusts and flammable gas in air) explosions in small to medium size industrial operations. Also, a protocol to conduct analysis and evaluation of explosion potential for industrial operations is presented.

Elements for thorough site inspections are defined based on uncovering potential failures and hazards. The best ways to review applicable standards and codes pertaining to the specific operations and occupancies are also covered.

The engineering hazard analysis (HA) method selection is critical to achieve the most complete evaluation of hazards in the operations. Methods and guidelines for their use will be discussed. Guidelines will also be presented for best selection of tests to evaluate the hazards. Extensive investigation to identify hazardous materials present in the industrial operations will be conducted.

Criteria for successful fire and explosion hazards analysis are also identified.
