Designing your dust collection system to meet NFPA standards — Part II
About 40 percent of combustible dust explosions reported in the US and Europe over the last 25 years have involved dust collectors. Part II of this two-part article covers how to eliminate ignition sources in the system, use explosion prevention and protection methods at the collector, and meet additional NFPA requirements. Part I appeared in the December 2008 issue.
Grounding the system equipment, selecting electrical components for your hazardous area classification, and protecting the exhaust fan are all ways to eliminate ignition sources in your dust collection system.
