Pmax. dP/dt max. KSt.

Three values that define explosion severity and provide the data behind DHAs and explosion protection system design.

An effective PSM program is more than documentation. An OSHA PSM Gap Analysis benchmarks your program against OSHA 29 CFR 1910.119 to identify gaps, prioritize improvements, and strengthen process safety.

Before you schedule a Dust Hazard Analysis, start here.

Our DHA Self-Check Guide helps you determine whether combustible dust requirements may apply to your facility.

Not every Process Hazard Analysis (PHA) uses the same methodology.

HAZOP is often the preferred choice for complex processes involving hazardous chemicals, continuous operations, and significant process risks.

Combustible dust hazards aren't one-size-fits-all.

Go/No-Go testing checks if a dust can explode as a cloud. Burning Behavior Screening checks if a settled layer will catch fire and keep burning.

Two different hazards. Two different tests.

A fire at the Peoples Cartage warehouse in Parkersburg, WV, reignited and spread across three connected warehouse buildings, prompting a state of emergency.

The cause remains under investigation.

A Dust Hazard Analysis (DHA) isn't a certification, permit, or pass/fail inspection.

It's a structured, risk-based evaluation that helps facilities identify combustible dust hazards and prioritize actions to reduce risk.

Hot surfaces are a common ignition source in facilities with combustible dust — but not all MIT tests measure the same thing.

MIT (Layer) = settled dust on surfaces

MIT (Cloud) = airborne dust in process equipment

Two tests. Two hazards. Material-specific data for both.

A combustible dust gap analysis helps identify weaknesses before they become incidents.

- Find gaps
- Prioritize risks
- Improve dust safety
- Align with current NFPA standards

Major Cold Storage Warehouse Fire and Ammonia Release
Boyle Heights, Los Angeles, California | June 17, 2026

The Boyle Heights cold storage warehouse fire is a reminder that industrial incidents often involve multiple hazards simultaneously.

Testing provides the data. A DHA evaluates the scenario.

Both are essential for combustible dust risk management.
