CANDLE FIRES AND FIRE HAZARDS
I. INTRODUCTION
The purpose of this investigation is to learn more about the characteristics of the candles that
start fires and the circumstances under which candle fires occur. Most candle fires result
from a physical malfunction on the part of the candle or from a miscalculation on the part of
the user. We are interested in data that capture (1) the physical characteristics of the candle’s
performance and (2) the user’s interaction with the candle. We are interested in anything that
is relevant to understanding the cause of the fire.
Please remember that no guideline can cover all the pertinent factors that may apply to a
particular incident. Include an explanation of any relevant factors in your narrative, even
when these factors have not been specifically mentioned in the guideline.
A. Background Information
Data from the National Candle Association show that the use of candles in the home has
increased dramatically over the last 15 years. Not only have candles experienced an
increase in popularity, but the types of candles available on the market and their proposed
uses have increased at a staggering rate. Candles are no longer intended for use only as
interior decorating items, but are now marketed as art items, air cleaners, therapy and
meditation devices, fragrance disseminators, and so forth.
Not surprisingly, the number of residential fires attributed to candles has also increased.
According to 1999 data1 , there were an estimated 12,800 fire service attended residential
fires caused by candles resulting in an estimated 1,530 injuries, 100 deaths, and 265.0
million dollars in property loss. While the number of total residential fires has been
steadily decreasing, the number of candle fires has, nonetheless, been steadily increasing.

Investigation Guideline

CPSC staff has worked with the candle manufacturers on an industry standard for candles.
The standard completed the ballot process in August 2004. As it stands, the standard
addresses issues of flame height, stability, end of life behavior (that the candle burns itself
out), and secondary ignition. Also under consideration for adding to the standard are
requirements for fuel pool (wax or gel) temperature, ignitable accessories, and holders or
containers.
A separate standard for candle accessories, including candle trim rings, tealight burners,
and potpourri burners, is expected to be ready for ballot in 2005. Additional fire
performance requirements are being developed for gel candles.
B. Product Description
The American Society for Testing and Materials (ASTM) defines a candle as “one or more
combustible wicks supported by a material that constitutes a fuel which is solid, semi-solid,
or quasi-rigid at room temperature, 68o to 80o F (20 to 27o C); it can also contain additives
that are used for color, odor, stability, or to modify the burning characteristics; the
combined function of which is to sustain a light-producing flame.”2 Traditionally, a candle
is cylindrical, but today’s candles come in many fanciful designs and shapes. The current
market is producing a vast variety of products that deviate from the traditional concept of a
candle. We are interested in all products comprised of wax and/or oil, that are burned with
a wick.
Types of Candles:
•

Taper or dinner candle: Long and thin, varies from 6 to 18 inches in length and can
burn up to 12 hours. Usually they are not scented, may be drip-resistant, and produce
little smoke or soot. Tapers are available in many colors. (ASTM definition: a slender
candle produced to be used with a candle accessory for support.)

•

Freestanding Candle: ASTM definition: a rigid candle (that is, pillar-shaped,
column-shaped, or figurine) recommended to be used on a heat-resistant,
nonflammable surface or on a cand le accessory.

•

Pillar or column candle: Thick in diameter. The shorter pillar candles can stand on
their own without the assistance of a candle holder/accessory, but should always be
used with a candle holder/accessory.

Investigation Guideline

•

Jumbo Pillars: These are thick, sturdy, and larger than pillar or column candles.
Sometimes called colonnades, these candles have multiple wicks (as many as three to
five). They are often scented and can have very long burning times.

•

Votive candles: Small candles that must be burned in a container since the wax melts
at low temperatures and creates a pool of molten wax. Votive candles were originally
used for religious or ceremonial purposes. (ASTM definition: a candle produced for
use fully within a candle accessory, specifically, a votive holder.)

•

Tealight candle: Small candles that come in their own metal holders to retain the
melted wax. Traditionally used to keep teapots warm, tealights are now used with a
variety of products. Potpourri burners are one example. (ASTM definition: a
cylindrical filled candle produced with a diameter and height of approximately 1.5 in.
(38 mm) and 0.75 in. (19 mm) respectively.)

•

Filled candles: Decorative and highly scented candles poured into various glass, tin,
or pottery pieces, called containers. (ASTM definition: a candle produced and used
within the same vessel.)

•

Gel candles: Some are clear and transparent taper style, while others come in
containers. Some gel candles have objects imbedded in the gel, for instance, wood or
plastic objects, seashells, or candy. (ASTM definition: a candle where the primary
fuel is a liquid, such as mineral oil, terpene type chemicals, or modified hydrocarbons
that are not mineral oil based, which may or may not contain organic functional
groups; it also contains a chemical agent to increase the viscosity (thicken) to a point
where the candle has a quasi-rigid property.)

•

Citronella: These are scented candles that have oversized wicks to prevent the flame
from extinguishing in a breeze. They produce an odor and smoke that deter insects and
are for outdoor use only. (The insect repellent quality of citronella candles is regulated
by the EPA, but CPSC has jurisdiction over the burning properties of the candle
itself).

•

Novelty: There are many candles that do not fit into the above categories. For
instance, wax bead candles; oil and water candles that are similar to oil la nterns in
which only the oil/wax substance floats in a bed of water. Candles shaped like
objects: cars, mushrooms, etc.; seasonal candles, such as, Halloween candles
depicting scary sights; Christmas decoration candles, and so forth also can be
classified as novelty candles.

Investigation Guideline

Candle container vs. candle accessory/holder:
•

Candle Containers: Some candles come in an encasement that is commonly called a
“container.” Candle containers are made of metal, glass, or plastic and completely
cover the bottom and sides of the candle, leaving only the wick and top of the candle
exposed.

•

Candle Accessory/Holder: On the other hand, a candle accessory/holder is some thing
that is placed under, on, or around the candle. Candle accessories/holders come in a
variety of shapes and sizes and often have a novelty or decorative function.
Accessories include candle trim rings, candle burners, and potpourri burners.

C. Specific Items of Interest
CPSC staff wants to learn as much as possible about the circumstances that led to the
fire. In cases involving candle trim rings, candle burners, or potpourri burners, collect
the fire candle and identical exemplars from the consumer, whe n available.
Candle malfunctions should be described in as much detail as possible. “Candle
malfunction” encompasses all aspects of the candle’s functioning, including the candle
holder and the candle container. Candle malfunctions include flare- ups (flames that are
excessively tall or large), wax that runs and transfers flame to other objects, candle
holders that catch fire, and candle containers shattering or igniting. There are many other
ways for candles to malfunction, and the above are a few selected for illustration.
It is essential that we get a full and complete description of the scenario in which the
candle fire occurred and any factors that contributed to the fire. We are interested in how
much attention was paid to the candle and whether there were people in the room with the
candle the entire time. Were the people in another room or some other part of the house
when the fire broke out? We are interested in how close the candle was to other things
that could catch fire. More precisely, we want to know exactly where the candle was and
what other objects were around the candle. Also how close were these objects to the
candle?
One of the focuses of this study is charting the course that led to the fire, and especially
the degree to which the candle was monitored. How the user interacted with the candle
is of interest. Determine whether he/she followed the instructions on the label (if there
was one). Describe the environment where the candle was burning. Were there any
occupants in the room with the candle when the fire started?
Page 4 of 12

Investigation Guideline

If a candle ignited a mattress/bedding, upholstered furniture, or wall covering,
include additional information about these products (see Appendices 15, 19, or
118).
Smoke alarms, fire sprinklers, and fire extinguishers are increasingly present in homes to
prevent fire deaths and limit damage. We are interested in learning how well these
products perform the jobs for which they were intended. When they were present but not
useful, we need to know why they weren’t useful, e.g. an inadequate number or
placement of smoke alarms, other installation problems, lack of maintenance, failure of
the products, unfamiliarity with the products, etc.

II. INSTRUCTIONS FOR COLLECTING SPECIFIC INFORMATION
A. Synopsis
Write a synopsis of the sequence of events that occurred before, during, and after the fire.
Specify the source of the ignition, the products involved, the extent of damage, and the
nature of all injuries and deaths.
B. Description of the Incident Environment
PRE- INCIDENT: Describe the home/residence where the candle fire occurred.
Describe the sequence of events that led up to the fire. Describe the course of activities
immediately before the candle was lighted and the course of events immediately before
the fire broke out. Include the candle’s placement in the environment, the room the
candle was in, and how close the candle was to the nearest object or material (if on a
shelf, how close to the next shelf, etc.).
Also include the reason the candle was in use, for instance, used as a light source,
used as a therapy, or used for decorative/ambience reasons.
INCIDENT: Describe the cause of the candle fire. Determine exactly what
happened to precipitate the fire. Describe the way the fire unfolded.

instance, was the flame excessively high (greater than two inches)?

•

If the user did not notice any irregular burning characteristics, did the candle function
properly, did it burn cleanly and smoothly?

•

Was the candle in a candle holder when purchased? If so, did the candle holder
malfunction in any way (e.g. paint or surface coating ignite; candle holder
overheat and ignite other materials; etc.)? If so, at what point in the fire
sequence? What were the dimensions of the candle holder (i.e. type/size of base,
length, etc.)? Was the holder stable?

•

Was the candle holder sold with the candle as one item?

•

If the candle was in a container (i.e., the encasement that the candle was
manufactured in), did something happen to the container that contributed to the fire?

F. Product Safety Standards
At present, there is a voluntary standard in place for Cautionary Labeling as well as a
fire safety voluntary standard that addresses requirements for flame height, stability,
end of life behavior, and secondary ignition.
A separate standard for candle accessories is expected to be ready for ballot in 2005.
Additional fire performance requirements are being developed for gel candles.
