What is DHA Assessment?

Dust Hazard Analysis (DHA) Assessment is a systematic evaluation process required by SS 667 and NFPA 660 to identify and evaluate the potential for dust explosions in industrial facilities. It is a critical component of workplace safety that helps organizations understand their dust explosion risks and implement appropriate protection measures.

Our comprehensive DHA assessments follow SS 667 and NFPA 660 standards and best practices, providing detailed analysis of dust hazards, ignition sources, and potential explosion scenarios. We help organizations comply with regulatory requirements while ensuring the safety of personnel and protecting valuable assets.

A thorough DHA assessment is the foundation for effective dust explosion prevention and protection, enabling organizations to make informed decisions about safety investments and risk management strategies.
