What is in-scope for Chapters 50–67 and what common exemptions apply?

Q: How do I know which chapter applies to my material?

First determine whether the material is a hazardous material and then identify the material class (e.g., corrosive, compressed gas). Use the definitions in § 5002 (Chapter 2) and then consult Chapter 50 plus the material-specific chapter (Chapters 51–67) referenced for that hazard.

Q: What if my total quantity just barely exceeds the MAQ in the tables?

If the quantity in a control area exceeds the MAQ you must comply with Chapters 50 and the applicable material chapter; that typically triggers permit, storage, containment and other design or operational requirements. Check § 5003.1.1 and the specific material chapter for required actions.

Q: Are consumer-size containers always exempt?

No. The exemptions in § 5001.1 are specific and limited (for example, consumer containers ≤ 1.3 gallons/5 L for certain goods). Don’t assume exemption — confirm the exact exception text in § 5001.1 .

Q: If a material has multiple hazards, what do I do?

The code requires that all hazards of a material be addressed — apply Chapter 50 plus each specific chapter that addresses each primary hazard (see § 5001.1 ).

If you store, use, handle or dispense hazardous materials you usually start with **§ 5001.1** (Chapters 50–67) and the definitions in **§ 5002** to see if your items are covered. Small retail consumer packages (individual containers ≤ 1.3 gallons / 5 L for certain products) and off‑site DOT transport are common exceptions; otherwise compare the total in each **control area** to the MAQ tables in **Section 5003.1** to see whether Chapter 50 and the material‑specific chapter apply.

What the code requires — 2–4 sentences

Chapters 50–67 of the California Fire Code regulate the prevention, control and mitigation of dangerous conditions arising from the storage, dispensing, use and handling of hazardous materials. The general scope is set by § 5001.1: these provisions apply to all hazardous materials except when a material or activity is expressly covered by a more specific chapter or listed exception. See § 5001.1 for the scope and the list of enumerated exceptions.

If you store, use, dispense or handle a hazardous material, start by checking § 5001.1 for scope, the definitions in § 5002, and the maximum allowable quantity per control area tables in Section 5003.1 to determine whether Chapters 50–67 apply.

Requirements in detail

Core rule (what makes something “in-scope”)

The general provisions require prevention, control and mitigation of dangerous conditions related to hazardous materials in storage, dispensing, use and handling (§ 5001.1). If there is a more specific chapter for the material (for example Chapters 51–67), those specific requirements apply in addition to or instead of Chapter 50 as stated in § 5001.1.

Definitions you must use first

Many key terms used throughout Chapters 50–67 are defined in Chapter 2 and collected under § 5002 (that section lists the defined terms such as CONTROL AREA, HAZARDOUS MATERIALS, MAXIMUM ALLOWABLE QUANTITY PER CONTROL AREA, SAFETY DATA SHEET (SDS), etc.). Consult § 5002 (Chapter 2 definitions) before applying thresholds or terms.

Quantities and the “maximum allowable quantity per control area”

Whether a storage/use condition is regulated at a higher level normally depends on the total quantity in a control area. Section 5003.1 directs users to the Tables 5003.1.1(1)–(4) (and other tables) for the maximum allowable quantity (MAQ) per control area; if you exceed the MAQ, Chapters 50 and the material-specific chapter apply. See § 5003.1.1.

Decision-relevant summary table

Decision dimension	Typical values/notes	Code reference
What triggers Chapters 50–67	Storage / dispensing / use / handling of hazardous materials (see defin.)	§ 5001.1
Where definitions live	Chapter 2 (terms like CONTROL AREA, MAQ, HAZARDOUS MATERIALS, SDS)	§ 5002 / Chapter 2
Quantity test	Compare site total in each control area to MAQ tables (Tables 5003.1.1). If > MAQ → Chapters 50 + material chapter apply	§ 5003.1.1
Retail/wholesale small-package exemption	Individual consumer containers ≤ 1.3 gallons (5 L) for listed consumer products (and other qualifiers) — see exceptions	§ 5001.1 (exceptions)
Material‑specific chapters	Use Chapter covering the hazard (e.g., compressed gases Chapter 53, corrosives Chapter 54) in addition to Chapter 50	Chapters 51–67 (see chapter headings)

Note: I could not find the text or numeric entries for Table 5003.1.1(5) in the files you provided. The code points users to Tables 5003.1.1(1)–(4) in § 5003.1.1, but the uploaded document excerpts do not contain Table 5003.1.1(5). I cannot invent its numbers; you should consult the full code (or the jurisdiction’s adopted tables) to get the table values.

Exceptions & special cases

Retail/wholesale consumer-package exceptions: medicines, foodstuffs, cosmetics and commercial or institutional products containing not more than 50% by volume water‑miscible liquid and with the remainder nonflammable are exempt provided individual containers are ≤ 1.3 gallons (5 L). Alcoholic beverages in retail/wholesale packaging ≤ 1.3 gallons (5 L) are similarly listed as an exception in § 5001.1.
Off-site transportation regulated by DOT is exempt from Chapters 50–67 (§ 5001.1, exception).
Some systems and equipment are regulated elsewhere and excluded here — examples in § 5001.1 exceptions include refrigeration systems (see Chapter 608 or § 608), stationary storage battery systems (see § 1207), aerosol products when meeting Chapter 51, and specific flammable-liquid provisions in Chapter 23 (motor fuel-dispensing).
Material-specific exceptions: many material chapters themselves state that quantities not exceeding the MAQ stated in Section 5003.1 may be handled under the general rules of Sections 5001/5003 (for example, corrosives Chapter 54 — see § 5403.1). That means low-quantity use/storage often stays under general Chapters unless MAQ is exceeded.

Common mistakes

Not looking up defined terms first. Many important words (CONTROL AREA, MAQ, HAZARDOUS MATERIALS) are defined in Chapter 2 and listed under § 5002 — apply those definitions before interpreting thresholds.
Assuming “small quantities” are always exempt. Only the specific exemptions in § 5001.1 apply (for example, the 1.3 gallon / 5 L retail-package limit). If MAQ per control area is exceeded you must comply with Chapter 50 and the specific chapter.
Failing to check material‑specific chapters. Many hazards have specialized chapters (e.g., compressed gases, corrosives, water‑reactive materials). Those chapters may add requirements even if Chapter 50 applies.
Relying on incomplete tables or outdated editions. The MAQ decision requires the correct table entry for the hazard class; Table 5003.1.1(5) was not available in your supplied files, so don’t assume values — consult the full adopted code.

Worked example — concrete scenario applying the rule with numbers

Scenario A — retail cosmetics display:

A small retail shop sells a line of cosmetics that are water‑miscible and the products are packaged in individual bottles of 1.0 gallon (3.8 L) each. The mixture is not flammable and the water‑miscible liquid content is ≤ 50% by volume.
Why this matters: § 5001.1 Exception 1 exempts “medicines, foodstuff, cosmetics and commercial or institutional products containing not more than 50 percent by volume of water‑miscible liquids … provided that such materials are packaged in individual containers not exceeding 1.3 gallons (5 L).” Because each container is 1.0 gallon (3.8 L) (≤ 1.3 gallons/5 L) and the water‑miscible content is ≤ 50%, the inventory described is within that retail‑packaged exception and is not treated as in‑scope hazardous materials for the purposes of Chapters 50–67. (Apply § 5001.1 Exception 1.)

Scenario B — same product repackaged into 6‑gallon drums:

If the same product were stored in 6‑gallon drums (each > 1.3 gallons / 5 L), the retail‑package exception no longer applies and you must compare the total quantity in each control area to the MAQ tables in Section 5003.1. If the total per control area exceeds the MAQ for that hazard class, Chapters 50 and the material‑specific chapter apply. Because the MAQ numeric values (including the entry for Table 5003.1.1(5) if relevant) are not contained in the supplied files, you must look up Table 5003.1.1 in the adopted code to complete the numeric comparison.

PART I—ADMINISTRATIVE

Chapter 1 Scope and Administration.

Chapter 1 establishes the limits of applicability of the code and describes how the code is to be applied and enforced. The provisions of Chapter 1 establish the authority and duties of the code official appointed by the authority having jurisdiction and also establish the rights and privileges of the design professional, contractor and property owner.

Chapter 2 Definitions.

Chapter 2 is the repository of the definitions of terms used in the body of the code. The user of the code should be familiar with and consult this chapter because the definitions are essential to the correct interpretation of the code and because the user may not be aware that a term is defined.

PART II—GENERAL SAFETY PROVISIONS

Chapter 3 General Requirements

General regulations contained in Chapter 3, are intended to improve premises safety for everyone, including construction workers, tenants, operations and maintenance personnel, and emergency response personnel.

Chapter 4 Emergency Planning and Preparedness

Chapter 4 addresses the human contribution to life safety during emergencies. Continuous training and scheduled fire, evacuation and lockdown drills can be as important as the required periodic inspections and maintenance of built-in fire protection features. The level of preparation by the occupants also improves the emergency responders’ abilities during an emergency.

53 COMPRESSED GASES

User notes:

About this chapter: Chapter 53 regulates the storage, use and handling of all flammable and nonflammable compressed gases, such as those that are used in medical facilities, air separation plants, industrial plants, agricultural equipment and similar occupancies. Also, this chapter regulates inert gases, such as CO 2 used for enrichment and beverage dispensing, that although inert are considered asphyxiants and in larger amounts pose a life safety hazard. Standards for the design, construction and marking of compressed gas cylinders and pressure vessels are referenced. Compressed gases used in welding and cutting, cryogenic liquids and liquefied petroleum gases are also regulated under Chapters 35, 55 and 61, respectively. Compressed gases that are classified as hazardous materials are also regulated in Chapter 50, which includes general requirements.

SECTION 5301—GENERAL

5301.1 Scope. Storage, use and handling of compressed gases in compressed gas containers, cylinders, tanks and systems shall comply with this chapter and NFPA 55, including those gases regulated elsewhere in this code.

Chapter 3 Occupancy Classification and Use.

Chapter 3 provides for the classification of buildings, structures and parts thereof based on the purpose for which they are used. Section 302 identifies the groups into which all buildings, structures and parts thereof must be classified. Sections 303 through 312 identify the occupancy characteristics of each group classification. In some sections, specific group classifications having requirements in common are collectively organized such that one term applies to all. For example, Groups A-1, A-2, A-3, A-4 and A-5 are individual groups for assembly-type buildings. The general term “Group A,” however, includes each of these individual groups. Other groups include Business (B), Organized Camps (C), Educational (E), Factory (F-1, F-2), High Hazard (H-1, H-2, H-3, H-4, H-5), Institutional (I-2, I-3, I-4), Laboratories (L), Mercantile (M), Residential (R-1, R-2, R-2.1, R-2.2, R-3, R-3.1, R-4), Storage (S-1, S-2) and Utility (U). In some occupancies, the smaller number means a higher hazard, but that is not always the case.

CFC § 102.1 Medium relevance — show source text

The IFC sets forth minimum requirements for these and other hazards and contains requirements for maintaining the life safety of building occupants; protecting emergency responders; and limiting the damage to a building and its contents as the result of a fire, explosion or unauthorized hazardous material discharge.

As described, the IFC has many types of requirements for buildings and facilities. The applicability of these requirements varies. An understanding of the applicability of requirements, as addressed in Sections 102.1 and 102.2, is necessary. Section 102.1 addresses when the construction and design provisions are applicable, whereas Section 102.2 addresses when the administrative, operational and maintenance provisions are applicable. Generally, the construction and design provisions apply to only new buildings or existing buildings and occupancies as addressed by Chapter 11. The administrative, maintenance and operational requirements are applicable to all buildings and facilities, whether new or existing.

ARRANGEMENT AND FORMAT OF THE 2025 CFC

Before applying the requirements of the CFC, it is beneficial to understand its arrangement and format. The CFC, like other codes published by the ICC, is arranged and organized to follow sequential steps that generally occur during a plan review or inspection.

The CFC is organized into seven parts. Each part represents a broad subject matter and includes the chapters that logically fit under the subject matter of each part. It is also foreseeable that additional chapters will need to be added in the future as regulations for new processes or operations are developed. Accordingly, the structure was designed to accommodate such future chapters by providing reserved (unused) chapters in several of the parts. This will allow the subject matter parts to be conveniently and logically expanded without requiring a major renumbering of the CFC chapters.

Chapter 48 Motion Picture and Television Production Studio Stages, Approved Production Facilities and Production Locations

On July 23, 1982, a Bell UH-1 Iroquois helicopter crashed at Indian Dunes in Valencia, Santa Clarita, California, during the making of Twilight Zone: The Movie. The crash killed three people on the ground and injured the six helicopter passengers. Those killed were actor Vic Morrow and child actors Myca Dinh Le and Renee Shin-Yi Chen. The incident led to years of civil and criminal action and was responsi- ble for the introduction of new procedures and safety standards in the filmmaking industry.

Chapter 49 Requirements for Wildland-Urban Interface Fire Areas

Requirements for Wildland-Urban Interface Areas are now located in Part 7 of Title 24, California Wildland-Urban Interface Code. The provisions of Part 7, the California Wildland-Urban Interface Code shall apply to buildings and structures located in the wildland-urban interface (WUI) or Fire Hazard Severity Zone.

PART V—HAZARDOUS MATERIALS

Chapter 50 Hazardous Materials—General Provisions

Chapter 50 contains the general requirements for all hazardous chemicals in all occupancies. The general provisions of this chapter are intended to be companion provisions with the specific requirements of Chapters 51 through 67 regarding a given classification of hazardous material.

Chapter 51 Aerosols

Chapter 51 addresses the prevention, control and extinguishment of fires and explosions in facilities where retail aerosol products are displayed or stored. Requirements for storing aerosol products are dependent on the level of aerosol product, level of sprinkler protection, type of storage condition and quantity of aerosol products.

Chapter 52 Reserved for future use.

Chapter 53 Compressed Gases

Chapter 53 regulates the storage, use and handling of all flammable and nonflammable compressed gases, such as those that are used in medical facilities, air separation plants, industrial plants, agricultural equipment facilities and in systems such as carbon dioxide beverage dispensing and carbon dioxide enrichment. Where classified as a hazardous material, Chapter 50 would apply along with specific applications such as those used in welding and cutting (Chapter 35), cryogenic liquids (Chapter 55) and liquefied petroleum gases (Chapter 61).

Chapter 54 Corrosive Materials

Chapter 54 addresses materials whose primary hazard is corrosivity; that is, the ability to destroy or irreparably damage living tissue on contact. Although corrosive gases exist, most corrosive materials are solid or liquid and classified as either acids or bases (alkalis). These materials may pose a wide range of hazards other than corrosivity, such as combustibility, reactivity or oxidizing hazards, and must conform to the requirements of this code with respect to all known hazards.

on Jul 18, 2025 11:14 AM (CDT) THEREUNDER.

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.

CFC § 1910.1200 Medium relevance — show source text

The DOL published a revised Hazard Communication Standard (DOL 29 CFR 1910.1200) to align with the GHS in March 2012. It became effective in May 2012. All manufacturers selling, producing or transporting chemicals in the United States are now required to comply with the GHS and provide this standardized hazard information on all Safety Data Sheets (SDS).

SDS are a primary source of information for identifying hazards for chemicals and mixtures containing hazardous materials. It can be helpful for fire code officials to become familiar with the GHS definitions and how they relate to CFC hazard definitions.

E104.2 GHS hazardous materials definitions comparison table. Table E104.2 provides a tabular presentation of the various definitions published within the California Fire Code . In addition, the table presents corresponding definitions, where available, from the 2012 edition of DOL 29 CFR 1910.1200 along with applicable hazard statement codes. DOL 29 CFR 1910.1200 aligns with the UN’s Globally Harmonized System of Classification and Labelling of Chemicals (GHS) . The table is not meant to imply perfect alignment between CFC and GHS definitions.

Frequently asked questions

How do I know which chapter applies to my material?

First determine whether the material is a hazardous material and then identify the material class (e.g., corrosive, compressed gas). Use the definitions in § 5002 (Chapter 2) and then consult Chapter 50 plus the material-specific chapter (Chapters 51–67) referenced for that hazard.

What if my total quantity just barely exceeds the MAQ in the tables?

If the quantity in a control area exceeds the MAQ you must comply with Chapters 50 and the applicable material chapter; that typically triggers permit, storage, containment and other design or operational requirements. Check § 5003.1.1 and the specific material chapter for required actions.

Are consumer-size containers always exempt?

No. The exemptions in § 5001.1 are specific and limited (for example, consumer containers ≤ 1.3 gallons/5 L for certain goods). Don’t assume exemption — confirm the exact exception text in § 5001.1.

Where can I find the numeric MAQ values?

Numeric MAQ values are in the Tables 5003.1.1(x) referenced in § 5003.1.1. The excerpt you provided references those tables but did not include Table 5003.1.1(5); consult the full adopted CFC tables for the exact numbers.

If a material has multiple hazards, what do I do?

The code requires that all hazards of a material be addressed — apply Chapter 50 plus each specific chapter that addresses each primary hazard (see § 5001.1).
