Case Study: Combustible Dust Safety in Aerospace Manufacturing 


A prominent aerospace manufacturing client approached seeking assistance in aligning with Dust Hazard Analysis (DHA) recommendations, which had identified non-compliance with NFPA guidelines for combustible dust hazards. 

Scope of Work


Dust Hazard Analysis (DHA) Compliance

  1. initiated the project by conducting a thorough assessment of the existing dust collectors and equipment in relation to NFPA guidelines for combustible dust hazards.
  2. The DHA report highlighted critical gaps that needed urgent attention to ensure compliance and mitigate the risk of combustible dust incidents.

System Consolidation and Upgrade

In response to the DHA proposed consolidating pickups from several older baghouses into a single, more efficient unit.

The baghouse underwent a comprehensive refurbishment, including the installation of new cartridge filters, pulse valves, solenoids, and updated hardware to meet industry standards.

NFPA-Compliant Safety Measures

To enhance safety measures, incorporated NFPA-compliant explosion vents and an explosion isolation valve.

Heavy gauge ductwork was strategically installed between the baghouse and the explosion isolation valve to meet the safety requirements outlined by NFPA.

Specialized Equipment Installation

A crucial aspect of the upgrade involved replacing the non-compliant flex hose discharge with an explosion-rated rotary valve.
The installation of explosion-rated components aimed to minimize the risk of dust-related incidents and ensure the safety of the environment.

The aerospace manufacturing facility achieved full compliance with NFPA guidelines for combustible dust hazards. tailored solutions provided the client with a robust and compliant dust collection system, as well as improved overall efficiency and dust collection performance.

Conclusion expertise in dust collection systems and commitment to safety facilitated a seamless transition for the aerospace manufacturing client. By addressing DHA recommendations and implementing NFPA-compliant upgrades, the project not only met regulatory requirements but also significantly bolstered the safety and efficiency of the client’s dust collection processes.
