Reactive Chemical Screening and Reactivity Testing

We run screening test programmes that characterise reactive hazards

What this study delivers

Reactive Chemical Screening
and Reactivity Testing

A large share of serious chemical incidents trace back to reactivity that was never recognised, whether an unstable intermediate, an incompatible combination, a water reactive solid or a slow self heating that only matters at drum or reactor scale. Reactive screening is the deliberately inexpensive early gate that surfaces this energy before you encounter it at scale. It uses structured laboratory protocols that probe exothermic onset, decomposition energy, water and air reactivity and binary incompatibility across the materials your process actually handles. We run the screening tier using DSC, Carius tube and mixing cell methods and read it against the Bretherick and Yoshida reactivity literature and CCPS reactive chemicals criteria, so what you receive is not raw thermograms but actionable decisions covering safe handling and storage segregation, where deeper adiabatic testing is warranted and the thermal margins your process design must respect.

Reactive Chemical Screening and Reactivity Testing Overview
Study execution

How the study is executed

A structured, facilitated process that runs from scope definition through close out and produces defensible, actionable outputs.

Literature & Structural Screening

Conduct literature screening per CCPS Reactive Chemicals, Bretherick's Handbook, Yoshida structural alerts, NOAA Chemical Reactivity Worksheet, identify reactive functional groups (peroxide, azide, nitro, diazo, acetylide, fulminate).

CHETAH Calculations

Apply CHETAH (Chemical Thermodynamic and Energy Hazard) algorithm, calculate maximum decomposition heat (ΔHdec), oxygen balance, and energy release index, align with ASTM CHETAH protocol and CCPS guidance.

DSC Thermal Screening

Conduct DSC per ASTM E537 / E2046 with controlled atmosphere (N₂ / air / O₂), temperature ramp 5 to 10°C/min, identify exothermic onset, peak, and energy release, align with EFCE / IChemE screening protocol.

Compatibility Screening

Conduct binary compatibility screening for each material pair in intentional contact or credible mixing scenarios, align with OSHA PSM Process Safety Information / CCPS Inherent Safer Reactive Hazard avoidance.

Hazard Classification & Risk Ranking

Classify material per Stoessel scenario class (1 to 5) and CCPS Reactive Chemicals hazard tier, risk rank for further testing (calorimetry, RC1 reactor, vent sizing), align with OSHA PSM Reactive Hazard programme.

Screening Report & Programme Integration

Compile reactive screening dossier with literature review, CHETAH output, DSC trace, compatibility matrix, integrate with Reactive Hazard Programme, HAZOP / SIL allocation, and OSHA PSM Process Safety Information.
