CFC · California Fire Code

Where are smoking, open flames and ignition-source controls specified?

Q: Where do I find the rule that says how close I can deposit hot ashes to a building?

See § 305.2 — hot ashes must not be deposited within 10 feet of combustible material and not within 2 feet of openings; the exception for covered noncombustible receptacles is also in § 305.2 .

Q: Can I have open candles on tables in my restaurant?

Open‑flame devices are generally prohibited in Group A occupancies but approved and stable table candle holders are allowed under the exceptions in § 308.1.1 and § 308.3 ; confirm with the local fire code official and follow holder/fuel restrictions.

Q: Must I post “No Smoking” signs?

Yes — the fire code official may require posting and § 310.3 authorizes posting and sets requirements for the content/placement of “No Smoking” signs where smoking is prohibited. Many specialty chapters (hazardous materials, storage, tents) also require conspicuous signs in their contexts.

Q: Are permits required to use torches or other open‑flame devices?

Often yes — § 308.2 lists activities that require permits (e.g., using a torch to remove paint, open‑flame uses in Group A/E occupancies, torches in wildfire risk areas); see the permit list in § 105.5 for specifics.

Q: If I work on a construction site, do standard smoking/open‑flame rules still apply?

Construction has its own ignition‑source controls. Chapter 33 / § 3305 addresses smoking, temporary heating and other ignition controls at construction sites; smoking is prohibited except in approved areas and signs are required per § 3305.2 and § 310 .

The California Fire Code regulates ignition sources in **§ 305** (clearances and ash handling), open flames in **§ 308** (where flames are allowed, required permits and device limits), and smoking in **§ 310** (prohibitions and “No Smoking” signage). Keep hot ashes away from combustibles (typically **10 ft**), follow special limits for flaming food (**8 in** pour height), get required permits for torches/open flames in certain occupancies, and post/enforce no‑smoking areas where flammable materials are present.

What the code requires — 2–4 sentences

The California Fire Code (CFC) places ignition-source controls, open-flame rules and smoking prohibitions primarily in § 305, § 308 and § 310. In plain English: maintain clearances from ignition sources and hot ashes, restrict and, in many occupancies, prohibit open flames (with limited permitted exceptions and permits), and prohibit smoking where it creates a hazard or where flammable/combustible materials are stored/handled. See § 305, § 308 and § 310 for the controlling text.

The single most important rule: control ignition sources by following the clearance rules in § 305, do not use open flames in prohibited occupancies or without required permits per § 308, and post/enforce “No Smoking” where smoking is prohibited per § 310.

Requirements in detail

1) Ignition sources — where the CFC sets clearance and handling rules

Key rule: keep approved clearance between ignition sources (luminaires, heaters, flame‑producing devices) and combustible materials; control hot ashes and spontaneous ignition sources. See § 305.1 and § 305.2.
Hot/ smoldering deposits: hot ashes, cinders, smoldering coals or oily/greasy materials must not be deposited in a combustible receptacle or within 10 feet of other combustible material or within 2 feet of building openings; there is an exception that reduces the minimum to 2 feet when using a covered, noncombustible receptacle on a noncombustible floor/stand. See § 305.2.
Open‑flame warning devices and devices liable to roll/ignite must not be used where they could fall into combustible material. See § 305.3 and § 305.4.

2) Open flames — where and when open flames are allowed or restricted

General prohibition and scope: § 308.1 states open flames, fire and burning are governed by § 308.1.1–§ 308.4.1 and other applicable sections. Open flames are broadly restricted in locations where highly flammable/combustible/explosive materials are used or stored. See § 308.1.1.
Occupancy restrictions: Open‑flame devices are prohibited in Group A (assembly) occupancies (subject to narrow exceptions for performance, ceremonial uses and approved table candle holders). See § 308.3.
Permits: specific uses of open flame require an operational permit (e.g., torches to remove paint, open flame uses in Group A/E occupancies, torches in wildfire risk areas). See § 308.2 and the permit list in § 105.5.
Special device limits and safeguards:
- Open‑flame decorative devices have construction and fuel limits (e.g., liquid/solid fuel devices > 8 oz must self‑extinguish and limit leakage if tipped). See § 308.3.1.
- Flaming foods/beverages: pouring/ladling is restricted to a maximum height of 8 inches above the receiving receptacle; flaming dishes must be prepared at the table and not carried while burning; the server must have a wet towel available to smother flames. See § 308.1.10.3–§ 308.1.10.5.

3) Smoking — where smoking is prohibited and signage requirements

Smoking control: § 310.1–§ 310.3 state the smoking or carrying of lighted tobacco/smoking materials is prohibited in areas listed in § 310.2–§ 310.8 and that the fire code official may require posting of “No Smoking” signs where smoking is prohibited. See § 310.1–§ 310.3.
Prohibited areas and clinical exceptions: smoking is prohibited where it would be a hazard or where flammable/combustible materials are stored or handled. There is a patient‑care exception for Group I‑2 when clinically required. See § 310.2 and § 310.2.1.
Signage: the fire code official is authorized to order posting of “No Smoking” signs (content, size, location approved by the official). See § 310.3.

Quick decision table (values and where to look)

Decision factor / threshold	Value or action to take	Code Reference
Clearance for hot ashes to combustibles	10 feet (do not deposit within 10 ft)	§ 305.2
Minimum separation from building openings for ashes	2 feet (do not deposit within 2 ft)	§ 305.2
Exception for ashes in covered noncombustible receptacle	2 feet (when covered receptacle on noncombustible floor)	§ 305.2
Open‑flame decorative device fuel limit (when >8 oz)	Device must self‑extinguish and limit fuel leakage	§ 308.3.1
Serving flaming food — maximum pour/ladle height	8 inches above receiving receptacle	§ 308.1.10.3
Open‑flame use in Group A occupancies	Prohibited (limited exceptions, and often requires permit)	§ 308.3
Smoking allowed	Only in approved/dedicated areas; post “No Smoking” where prohibited	§ 310.1–§ 310.3
Permits required for open flames/torches/paint removal	Yes — see permit list (Section 105.5 and § 308.2)	§ 308.2, § 105.5

Exceptions & special cases

Ceremonial, theatrical or religious uses of open flame in prohibited occupancies: allowed only with approval and under restrictions to avoid ignition/injury (see § 308.1.1 exceptions and § 308.3).
Table candles in dining establishments: allowed if approved and stable candle holders are used (see § 308.1.1 exception and § 308.3).
Ash disposal exception: ash may be deposited within 2 feet of combustibles if placed in a covered, noncombustible receptacle on a noncombustible floor/stand (see § 305.2).
Tents / membrane structures: smoking is prohibited in tents, and open flames/heat devices are limited to positions not within 10 feet of the tent while open to the public; separate tent rules are in the tents/membrane‑structure chapter (see § 3108).
Occupancy‑specific rules: other chapters (hazardous materials, storage, specific occupancies) overlay additional ignition‑control rules such as 25‑ft smoking offsets around outdoor hazardous storage—follow those sections where applicable. See the hazardous‑materials guidance in § 5003.7.1 and storage sections.

Common mistakes

Assuming “No Smoking” signage is optional. The fire code official can require and order posting of signs; many provisions (e.g., hazardous materials, storage areas) require conspicuous signs that comply with § 310. See § 310.3 and related hazardous‑materials sections.
Using open‑flame devices in Group A/assembly areas without approval or permit. Group A is generally restricted; permitted exceptions (ceremony, theatrical) have strict safeguards. See § 308.3 and § 308.2.
Overlooking ash separation distances. Placing hot ashes in ordinary combustible containers or too close to openings violates § 305.2 unless the exception conditions are met.
Mixing chapters: Many chapters (haz‑mat, storage, tents, construction) add their own ignition‑source and smoking rules; enforcement is by overlapping requirements — always check the specific occupancy chapter in addition to § 305–308–310. Examples: tents (3108), hazardous materials (5003), construction (3305).

Worked example — restaurant serving a flambé dessert (concrete scenario)

Scenario: A dining room (Group A occupancy) at a restaurant wants to serve flaming desserts tableside.

Is open flame allowed in a Group A dining room?
- By default open‑flame devices are prohibited in Group A; exceptions permit use only for ceremonial/theatrical or in approved and controlled ways. See § 308.3.
Practical application of the exceptions and safeguards:
- Use approved, stable table candle holders (if candles are desired) OR treat the flaming dessert as a controlled food service activity. See § 308.1.1 and § 308.3.
- If serving flaming food, follow the flaming‑food limits: the pouring/ladling height must not exceed 8 inches above the receiving receptacle; prepare the flame only in the immediate vicinity of the table and do not transport while burning. Also have a wet cloth immediately available to smother flames if needed. See § 308.1.10.3–§ 308.1.10.5.
- Confirm whether a permit is required under the local authority for open‑flame uses in Group A; § 308.2 requires permits for open‑flame uses in Group A in many cases. See § 308.2 and permit list § 105.5.
Checklist the restaurant must satisfy before allowing the service:
- Obtain approval/permitting from the fire code official if required (see § 308.2).
- Use approved containers/holders and limit pouring height to ≤ 8 inches (measure and train staff). § 308.1.10.3.
- Post or enforce No Smoking rules as required for the dining area (per § 310), and ensure staff know how to smother flames immediately (wet towel available). § 310.3, § 308.1.10.5.

Result: If the restaurant follows the above (approved device/holder, pour height ≤ 8 in, immediate wet towel, and any required permit/approval), the table‑side flaming dessert may be permitted under the CFC exceptions and requirements; otherwise it must be prohibited.

Yes — the fire code official may require posting and § 310.3 authorizes posting and sets requirements for the content/placement of “No Smoking” signs where smoking is prohibited. Many specialty chapters (hazardous materials, storage, tents) also require conspicuous signs in their contexts.

Are permits required to use torches or other open‑flame devices?

Often yes — § 308.2 lists activities that require permits (e.g., using a torch to remove paint, open‑flame uses in Group A/E occupancies, torches in wildfire risk areas); see the permit list in § 105.5 for specifics.

If I work on a construction site, do standard smoking/open‑flame rules still apply?

Construction has its own ignition‑source controls. Chapter 33 / § 3305 addresses smoking, temporary heating and other ignition controls at construction sites; smoking is prohibited except in approved areas and signs are required per § 3305.2 and § 310.
