High-Piled Storage
Analysis & Consultation

A high-piled storage analysis determines whether your storage arrangement triggers special requirements for protection and permitting. Generally, high-piled combustible storage applies when materials exceed 12 ft in height (or 6 ft for certain high-hazard commodities like Group A plastics). Tier One Fire Consulting evaluates your commodities, heights, and layouts to confirm applicability and define the right compliance path.

We compare ESFR and CMDA + in-rack designs using your commodity class, storage height, rack geometry, and ceiling conditions under NFPA 13. Our goal is the safest, most cost-effective solution that meets code intent, minimizes obstructions, and supports future flexibility.

Yes. We routinely address ASRS, multi-deep and shuttle systems, and mezzanine/rack platforms, accounting for clearances, access, heat release, and obstructions. Our analyses translate into clear protection criteria and permit-ready documentation for AHJ review.

Hazardous materials can change your MAQs, control areas, and protection strategy. Tier One Fire Consulting integrates MAQ calculations, control area design, and separation/compatibility requirements with your HPS plan to keep operations compliant and defensible during permitting.

Deliverables typically include an HPS code summary, protection criteria, plan sheets, calculations (if applicable), and a technical narrative, plus AHJ coordination (pre-apps, responses, revisions). We focus on accuracy and clarity to reduce resubmittals and keep projects moving.
