How are hazardous materials classified and reported on HMIS?
If your building stores hazardous materials you must file a separate HMIS that lists each material grouped by hazard class and shows its identity, CAS number, whether it’s a mixture, physical state, maximum quantity and storage conditions. Use Appendix E to classify hazards and follow the Appendix H HMIS fields; update the HMIS within 30 days if hazard classes change or amounts increase by more than 5 percent.
Last reviewed: July 6, 2026
What the code requires — 2–4 sentences
A separate Hazardous Materials Inventory Statement (HMIS) must be provided for each building or exterior facility that stores hazardous materials, and it must list each material by hazard class and include specific identification and quantity details. The HMIS form lists items such as hazard class, common/trade name, chemical name (and constituents if a mixture), CAS number, pure/mixture and physical state, maximum aggregate quantity, and storage conditions (type, temperature, pressure) — see § H2.1 of Appendix H.
Where a permit application is required the HMIS must include similar fields (product name, components, CAS, location, container size, hazard classification and amounts) per § 5001.5.2.
The single most important rule: provide a separate, complete HMIS for each building/exterior facility that lists every hazardous material grouped by hazard class and showing identity, quantity and storage conditions. § H2.1.
Requirements in detail
Who must file an HMIS
- A separate HMIS is required for each building (including appurtenant structures) and each exterior storage facility where hazardous materials are stored — § H2.1.
- When a permit application is required, the HMIS content must meet the items listed in § 5001.5.2.
What information must be on the HMIS
Use the table below to decide what to report and where it is required in the code.
| Decision dimension (what to report) | What you must provide / acceptable values | Code Reference |
|---|---|---|
| Hazard class | List each material by hazard class (use CFC hazard categories / GHS guidance in Appendix E as needed) | § H2.1 ; Appendix E (hazard category definitions) |
| Common or trade name | The name used at site / on labels | § H2.1 |
| Chemical name / constituents | Chemical name; for mixtures list major constituents and concentrations | § H2.1 |
| CAS number | CAS number if available (29 C.F.R. source) | § H2.1 |
| Pure vs. mixture; state | Indicate Pure (P) or Mixture (M) and Solid (S) / Liquid (L) / Gas (G) | Appendix H inventory instructions (descriptive codes) and § H2.1 |
| Maximum aggregate quantity | Provide the maximum aggregate quantity stored at any one time (specify units: LB, GA, CF, etc.) | § H2.1; HMIS instructions (units and average daily amount) |
| Storage conditions | Storage type (tank, drum, cylinder, etc.), temperature (ambient/greater/cryogenic), and pressure codes | § H2.1; Appendix H storage codes table (Type / Temperature / Pressure) |
| Location / container size / amounts in use | For permit HMIS: location where stored/used, container sizes, amounts in storage, in closed systems, and in open systems | § 5001.5.2 |
| Hazard classification method | Use the CFC hazard category definitions in Appendix E (which cross-walks to GHS) when classifying | Appendix E (Table E104.2 and related guidance) |
Notes on classification:
- Appendix E provides the CFC hazard category definitions and a comparison to GHS (useful when SDS / GHS labels are the source of classification). Use the Appendix E tables to determine whether a material is a flammable, oxidizer, water-reactive, compressed gas, corrosive, unstable/reactive, etc.
Change reporting & amendment timing
- If storage of materials changes so that a new hazard class is added or an existing hazard class increases by more than 5 percent, an amended HMIS must be provided within 30 days — § H2.2. Bold threshold: 5 percent.
Cross-references that affect what you report
- The permit HMIS fields listed in § 5001.5.2 (product name, component, CAS, location, container size, hazard classification, amounts in storage and use) must be completed where the fire code official requires an HMIS as part of a permit application.
Exceptions & special cases
- Appendix H includes an exception: materials “satisfactorily demonstrated not to present a potential danger to public health, safety or welfare, based on the quantity or condition of storage” may be exempted from Appendix H requirements if approved by the authority having jurisdiction — see Appendix H (Scope / H1.1 Exceptions).
- Appendix H explicitly excludes certain metals (chromium, copper, lead, nickel, silver) from being treated as hazardous materials for Appendix H purposes unless stored in a friable, powdered or finely divided state — Appendix H exceptions.
- Appendix E notes that CFC categories do not align perfectly with GHS; when using SDS/GHS information, consult Appendix E’s crosswalk (Table E104.2) to map classifications.
Common mistakes
- Failing to group entries by hazard class (the HMIS must list materials grouped by hazard class) — Appendix H requires listing “by hazard class.”
- Omitting the CAS number or major constituents for mixtures — Appendix H and the HMIS instructions require CAS and constituents where available.
- Not indicating whether a material is pure vs. a mixture and failing to record the physical state (S/L/G) — Appendix H inventory codes require these descriptors.
- Not updating the HMIS within 30 days after exceeding the 5 percent increase threshold (for a hazard class) — § H2.2.
- Relying solely on a manufacturer’s trade name without providing chemical identity or CAS when required by the HMIS instructions — Appendix H requires chemical name / constituents.
Worked example — applying the rule with numbers
Scenario: A small lab in one building stores the following at maximum aggregate on-site at one time:
- Acetone (flam. liquid, hazard class: Flammable Liquid) — 20 gallons (open containers used occasionally).
- Hydrochloric acid 10% solution (corrosive) — 15 gallons in drums.
- Compressed nitrogen cylinders (inert compressed gas) — 6 cylinders.
How to report on the HMIS (per § H2.1 and HMIS instructions):
- Create a separate HMIS for the building (required by § H2.1).
- For Acetone:
- Hazard class: Flammable Liquid (use Appendix E to confirm category if needed).
- Common/trade name: Acetone.
- Chemical name: Propanone. CAS number: 67-64-1.
- Pure/mixture: P (Pure), State: L (Liquid).
- Max aggregate quantity: 20 GA (gallons).
- Storage condition: e.g., D = Steel Drum or appropriate code from Appendix H storage codes.
- For Hydrochloric acid (10%): list hazard class (Corrosive), chemical name, CAS if available, M or P as applicable, state L, max aggregate quantity 15 GA, storage type (drum).
- For Compressed nitrogen: hazard class Compressed gas (Appendix E definition for compressed gases), common name, CAS (if used), state G, container (cylinder), number of cylinders and typical cylinder capacity (report container size).
- If next month the lab adds 2 gallons of another flammable solvent such that the total flammable liquids hazard class increases by >5% compared to the previously reported amount, the HMIS must be amended and resubmitted within 30 days per § H2.2.
Related provisions
- § 5001.5.2 — Hazardous Materials Inventory Statement (HMIS) required fields for permit applications.
- § 5001.5.1 — Hazardous Materials Management Plan (HMMP) content and site-plan requirements (HMMP often accompanies HMIS).
- § 407.5 — Requires HMIS where the fire code official requires it (hazard communication cross-reference).
- Appendix E — Hazard categories and definitions; crosswalk to GHS for classification.
Important note about § 5001.2.1:
- The file search results available to me include index references to § 5001.2.1 (for example, “Mixtures 5001.2.1”) but the full text of § 5001.2.1 was not retrieved in the provided documents, so I cannot quote or ground specific language from that section here.

Appendix G Cryogenic Fluids—Weight and Volume Equivalents
Appendix G gives the fire code official and design professional a ready reference tool for the conversion of the liquid weight and volume of cryogenic fluid to their corresponding volume of gas and vice versa and is a companion to the provisions of Chapter 55 of this code. Note that this appendix is for information purposes and is not intended for adoption.
Appendix H Hazardous Materials Management Plan (HMMP) and Hazardous Materials Inventory Statement (HMIS) Instructions
Appendix H is intended to assist businesses in establishing a Hazardous Materials Management Plan (HMMP) and Hazardous Materials Inventory Statement (HMIS) based on the classification and quantities of materials that would be found on-site, in storage or in use. The sample forms and available Safety Data Sheets (SDS) provide the basis for the evaluations. It is also a companion to CFC Sections 407.5 and 407.6, which provide the requirement that the HMIS and HMMP be submitted when required by the fire code official.
Appendix I Fire Protection Systems—Noncompliant Conditions
The purpose of Appendix I, which was developed by the ICC Hazard Abatement in Existing Buildings Committee, is to provide the fire code official with a list of conditions that are readily identifiable by the inspector during the course of an inspection utilizing the CFC. The specific conditions identified in this appendix are primarily derived from applicable NFPA standards and pose a hazard to the proper operation of the respective systems.
Appendix J Building Information Sign
Appendix J provides design, installation and maintenance requirements for a Building Information Sign (BIS), a fire service tool to be utilized in the crucial, initial response of firefighters to a structure fire. The BIS placard, which is in the shape of a fire service Maltese Cross, is designed to be utilized within the initial response time frame of an incident to assist firefighters in their tactical assessment of the construction type and hourly rating, fire protection systems, occupancy type, content hazards and special features that could affect tactical decisions and operations.
Appendix K Construction Requirements for Existing Ambulatory Care Facilities
Appendix K was created by the ICC Ad Hoc Committee on Healthcare (AHC) and is intended to provide jurisdictions with an option for assessing minimum fire and life safety requirements for buildings containing ambulatory care facilities. These requirements are presented as an appendix so that the adopting authority can exercise judgment in the adoption and application of this section since the ambulatory care facility requirements are fairly new to the codes. The technical requirements are based on the CBC language, which is consistent with the overall concept of the current federal requirements.
Appendix L Requirements for Firefighter Air Replenishment Systems
Appendix L provides for the design, installation and maintenance of permanently installed firefighter breathing air systems in buildings designated by the jurisdiction. The system has been called a “standpipe for air” and consists of stainless steel, high-pressure piping that is supplied by on-site air storage or fire department air supply units. Air-filling stations are then located throughout the building, allowing firefighters to refill breathing air cylinders inside the fire building.

Frequently asked questions
What’s the difference between the HMIS required by Appendix H and a SARA Tier II report?
An Appendix H HMIS lists materials by hazard class and includes the specific fields in § H2.1; the code allows SARA Title III (Tier II) reports or other approved statements to satisfy the HMIS requirement where accepted by the fire code official — see § 5001.5.2.
When exactly must I submit an amended HMIS?
Submit an amended HMIS within 30 days if you add a new hazard class or if the quantity of a hazard class increases by more than 5 percent relative to the last HMIS — § H2.2.
Do I need to list trade-secret chemicals on the HMIS?
Trade-secret or proprietary information is protected by state law, but Appendix H still requires listing materials; the HMIS/map may mark trade-secret entries as confidential per applicable federal/state/local laws — Appendix H scope and confidentiality note.
How should mixtures be reported?
Appendix H requires the chemical name and major constituents and concentrations if a mixture; if the mixture has a distinct CAS number, report it, otherwise report CAS numbers of constituents as possible — § H2.1 and Appendix H inventory instructions.
Where do I find the CFC hazard class definitions to classify a material?
Use Appendix E (Hazard Categories and the Table E104.2 crosswalk to GHS) to determine the appropriate CFC hazard category.
