Chemical Compatibility Study – Chemical Segregation and Handling.

Chemical segregation and handling study for hazardous material storage in Qatar by iFluids Engineering

Identify, Classify & Safely Store Chemicals to Prevent Fires, Reactions & Regulatory Non-compliance.

Why Conduct a Chemical Segregation Study?

Improper storage and handling of hazardous chemicals is one of the leading causes of warehouse fires, toxic gas releases, and explosions across oil & gas terminals, chemical warehouses, laboratories, and manufacturing sites in Qatar. In most cases, the root cause is chemicals with incompatible properties being stored or handled together without proper segregation.

At iFluids Engineering Qatar, our Chemical Segregation and Handling Study combines a rigorous chemical compatibility study, hazardous chemical storage assessment, and chemical warehouse safety review into a single, audit-ready engineering package. The study is geared to:

  • Safe segregation of hazardous materials by HAZMAT class and reactivity type
  • Evaluation of water compatibility to support safe firefighting response
  • Compliance with NFPA 400, International Fire Code (IFC), OSHA, UN compatibility guidelines, and Qatar’s statutory HSE requirements

What’s Included in Our Study?

Our chemical storage assessment and warehouse compliance review covers the following areas:

AreaDescription
Chemical Compatibility StudyCross-analysis of how each stored chemical reacts with others and with water
Chemical Segregation Study & Storage LayoutSeparation distances, storage zoning, ventilation needs, and a compliant chemical storage layout
Hazard / HAZMAT ClassificationChemical grouping per HSG-71 (UK), US DOT, BG RCI (Germany), GHS, and NFPA hazard classes
MAQ Calculation & Control Area AssessmentMaximum Allowable Quantity verification and control-area compliance in line with NFPA 400
Secondary Containment Design & Spill Containment AssessmentPrimary and secondary containment sizing, plus spill containment adequacy verification
Fire Code Compliance & Firefighting Water ReactivityIdentification of chemicals where water use during firefighting may be hazardous
Safe Handling SOPsStep-by-step procedures and required PPE for chemical transfer, use, and storage

Detailed Methodology – How We Perform the Study

Our Chemical Compatibility & Storage Compliance Study is developed on internationally recognized best practices, including NFPA 400, the International Fire Code (IFC), OSHA, UN compatibility guidelines, HSG-71 (UK), US DOT, and BG RCI (Germany) tailored to the operating context of industrial and logistics facilities in Qatar. The study follows a structured, six-stage methodology:

a) Kickoff & Data Collection

  • Kickoff meeting to confirm study scope, inventory boundaries, and points of contact
  • Collection of the current chemical inventory, Safety Data Sheets (SDS), storage details, and container/packaging sizes, along with reasonably anticipated future inventory
  • Review of warehouse drawings, fire protection details, and existing containment or civil drawings
  • Review of existing containment systems and any prior compliance studies

b) Site Walkthrough

  • Verification of actual storage conditions, racking arrangement, and segregation practices against SDS requirements
  • Confirmation of ventilation, spacing, clearances, and fire protection system adequacy (detection, suppression, spill containment)
  • Identification of hazards, incompatibilities, and any immediate non-conformances observed on site

c) Chemical Compatibility & Segregation Study

  • Evaluation of SDS Section 10 (stability & reactivity) data across the full inventory, current and anticipated
  • Development of a chemical compatibility matrix specific to the facility’s inventory
  • Development of a storage segregation chart/matrix by hazard class
  • Identification of incompatible chemical groups and definition of required separation distances and physical barriers

d) Engineering & Containment Assessment

  • Primary containment calculations in accordance with NFPA 400
  • Secondary containment sizing and spill containment verification
  • MAQ (Maximum Allowable Quantity) calculations based on current and reasonably anticipated storage quantities
  • Control-area assessment and separation distance / fire barrier verification
Secondary containment sizing and spill containment engineering assessment

e) Layout Development

  • Development of an NFPA / IFC-compliant warehouse storage layout
  • Definition of segregated storage zones and spill containment zones
  • Layout issued in both PDF and DWG formats

f) Gap Analysis & Recommendations

  • Practical, prioritized remediation recommendations for each identified gap
  • Identification of gaps and non-conformances against applicable codes and regulatory requirements

Water Compatibility & Firefighting Considerations

A dedicated step within the compatibility study investigates how each chemical behaves with water — an important consideration for firefighting. Chemicals marked “not compatible with water” may not be reactive on their own, but water use around them can be counterproductive or dangerous during a fire.

  • Example: Oils and hydrocarbon solvents — water use can spread the fire
  • Example: Reactive metals — water can generate explosive hydrogen gas

Example Reactions Considered in Compatibility Checks

Incompatible CombinationPotential Hazard
Acids + HypochloritesChlorine gas release
Acids + AlkalisHeat generation
Acids + SulfidesHydrogen sulfide gas
Flammables + OxidizersFire / explosion risk
Water-reactive metals + WaterHydrogen gas explosion
