Dust Hazard Analysis (DHA)

Dust Hazard Analysis (DHA)

Comprehensive Dust Hazard Analysis services compliant with Singapore Standard SS 667 and NFPA 660 to protect your facility from combustible dust hazards.

About This Service

Overview

Combustible dust is one of the most under-recognised yet devastating workplace hazards. A Dust Hazard Analysis (DHA) is a systematic evaluation required under Singapore Standard SS 667 and NFPA 660 to identify, assess, and mitigate fire and explosion risks associated with combustible dust in your facility. DASH Consult brings deep expertise in combustible dust science and industrial safety engineering to help organisations meet their DHA obligations.

Our DHA methodology follows the process-hazard-analysis framework outlined in SS 667 and NFPA 660 — the consolidated standard that replaces the former NFPA 652, 61, 484, 654, 655, and 664. We evaluate every stage of your material handling process, from receiving and storage through processing, conveying, and dust collection, identifying ignition sources, fuel accumulations, and confinement scenarios that could lead to flash fires, deflagrations, or secondary explosions.

Upon completion, you receive a prioritised action plan with practical engineering and administrative controls tailored to your operations. Whether you are a food manufacturer, pharmaceutical producer, metalworking facility, or chemical processor, our team ensures your DHA is thorough, defensible, and aligned with Singapore regulatory requirements and international standards.
