Prevent Combustible Dust Explosions with Nitrogen Inerting

Targeted use of blanketing with inert gas offers an effective strategy for preventing combustible dust explosions in CPI facilities
Combustible dust is a critical safety concern for the chemical process industries (CPI). The use of nitrogen gas as an inert blanket offers an effective approach to preventing combustible dust explosions by displacing the oxidant required for an explosion. Nitrogen inerting is a practical solution to help prevent the devastation to personnel and property that can result from combustible dust explosions. Moreover, while nitrogen is not the right solution for every system, when properly designed and installed, it is often safer, less expensive and easier to maintain than alternative mechanical solutions. Using a set of examples, this article explores how nitrogen can be used to prevent — not just mitigate — combustible dust explosions in CPI facilities.
Regulations expand dust hazard scope
In December 2015, the Occupational Safety & Health Administration (OSHA; Washington, D.C.; www.osha.gov) will begin fully enforcing its new Hazard Communication (HazCom) standard, which adopts the Globally Harmonized System for the Labeling and Classification of Chemicals (GHS). Originally announced in 2012,…
