NFPA Dust Compliance Inspection


Failure to install, maintain or inspect dust collectors to the recognized NFPA standards can result in dangerous levels of explosive dust accumulations inside the facility. If the dust becomes suspended in sufficient quantities, an explosion can occur with devastating results. Recent explosions in the sawmill industry have raised the awareness of the need to provide and maintain the proper NFPA compliant explosion safety devices on dust handling equipment.


The course objective will be to provide participants with the basic training to conduct explosion protection device inspections as per the frequency recommended by NFPA and or the equipment supplier. The deliverable will be a base case inspection procedure for NFPA compliance which participants can modify for their respective facilities.

Course Outline

  • How to prepare an NFPA Gap analysis. The objective of the Gap analysis is to identify what is required to update the dust control systems to meet the objective of safe operation as defined by the NFPA, local building codes, Local and National Fire Marshall, insurance and Worksafe. The Gap analysis  identifies what needs to be done, when and methods for approximating cost.
  • How to prepare an interim action plan through Gap Analysis to Compliance certification. Included will be strategies for contractor bidding, self-source procurement, third party review specifications, identifying opportunities for a Turnkey project, communication and documentation for Authority Having Jurisdiction (AHJ) reporting
  • Using compliance items from the Gap Analysis, review common construction and design problems during  upgrades to meet the respective codes. This section will include resources and tools used to evaluate what is required to upgrade existing dust collection systems, eliminating the high costs of replacement.
  • Methods and requirements for developing an annual compliance documentation plan. This will include training in testing and report preparation to ensure the proper maintenance and testing as per the manufacturers or Authority Having Jurisdiction is being completed. Hands on training with typical flow, thickness, ground check meters will be included.


Registration/check-in will start at 8:00 a.m. with sessions to begin at 8:30 a.m. and adjourn at 4:00 p.m. Lunch is on your own from 12:00 noon to 1:00 p.m. There will be 15 minute mid-morning and afternoon breaks.
