Wood Dust Combustibility
This section is provided to help mitigate through education,
the potential dangers in using wood, creating sanding and
sawdust and then breathing or coming in contact with that
dust.
Wood dust is combustible. It will:
• Burn easily when exposed to an open flame or is heated
sufficiently.
• Explode when suspended in the air in sufficient
quantities and/or it comes in contact with an ignition
source
• Ignite through spontaneous combustion if it is
mixed with oils.
Wood dust is a potential carcinogen with an
increased risk of contracting nasal cancer after repeated
and long-term
exposure to wood dust.
Wood dust is the medium by which
potentially irritant chemicals found in wood can cause
allergic dermatitis
and respiratory
reactions.
Allergic reaction
Most all woods, cosmetic, as well as imported, contain
chemical compounds which some people can find irritating
during cutting
or sanding. However, the woods themselves are not
hazardous, skin contact or inhalation of wood dust can
be. As
this is the usual means to convey the potentially
irritating compounds
found in most woods, installers, because of their
repeated exposure to sanding and saw dust, need to be
aware
of
the possibility of allergic reaction. Your flooring,
once coated
with a finish, is basically inert.
This allergic reaction
comes in two forms:
• It can be respiratory, cause sneezing and/or breathing
problems or
• It can be in the form of a skin irritant causing
itching and in rare cases allergic reactions such
as painful
rashes.
As an individual becomes sensitized to a wood
over time these reactions get stronger. In one case, a
famous installer,
who has been using exotic wood in elaborate pattern
work extensively over the last twenty years and had
obviously
been previously sensitized as a result, experienced
serious contact dermatitis and broke out in painful
rashes when
installing
Bolivian Rosewood floor. So it can happen.
In general,
preventing measures such as having good dust collection
attached to your sanders, wearing
long sleeve
shirts and hats to avoid skin exposure, and showering
after being exposed to dust, will minimize the
skin irritant potential. Wearing a good dust respirator
will mitigate
the respiratory
dangers.
However, for those who wish to test their
skins allergic reactive potential prior to working with
large quantities
of dust may perform skin patch test. Take a small
quantity of fine dust from the wood being used
and place under
a round band-aid on the inside of your forearm.
Leave in
place for
24 hours and then remove. If any serious skin
irritation is present, DO NOT proceed. We recommend this
test
be performed prior to using any woods in quantity
and/or in very dusty
conditions, which we have noted as having high
potential for allergic reaction. On the following
page is a
chart, which list woods and potential allergic
reactions.
Wood dust is also extremely combustible.
Keep in a cool dry place away from ignition sources.
Avoid
creating
dust clouds
which in turn create severe explosion hazards
should it come in contact with an ignition
source. For
more information,
please refer to the OSHA Material Safety Data.

All wood dust can cause respiratory problems. Many types
of wood dust can also cause allergic reactions when coming
in
contact
with your
skin. The
woods listed
are known to have a higher degree of risk of reactive problems.
Please take precautions such as good ventilation, dust
masks, etc., to limit
skin contact
with the dust to avoid potential problems especially when
using woods from the 1st group above.
Section IV: Fire
and Explosion Data
Flash Point: N/A
Fire Extinguishing Media: Determined by surrounding fire.
Use a water spray to wet down wood dust to reduce likelihood
of
ignition or dispersion
of
dust into the air. Remove burned or wet dust to safe open
area after fire is out.
Flammable Units (Percent by Volume):
Lower: Variable **White pine flour/dust-ca. 0.035 ox/ft3
Upper: Not available
**Values depend on wood type, particle size, level of moisture
in wood, time and rate of heating, etc. (Typically, white
pine auto
ignition
would be at
about 390 - 500 degrees F.)
Special Fire Fighting Procedures & Equipment: None
Unusual Explosion and Fire Hazards: Wood dust
is a strong to severe explosion hazard if a dust “cloud” contacts
an ignition source. Partially burned dust is especially
hazardous if dispersed in air. 212 degrees F has
been suggested as the upper temperature limit for continuous
exposure for wood without risk of ignition (wood dust may
require a still lower temperature).
For example: white pine flour/dust as a “cloud” in
air requires 0.040 J min. energy for ignition and can produce
an explosion pressure of 113
psig max.
Section V: Reactivity Data
Stability: _Unstable X Stable
Conditions to Avoid: N/A
Incompatibility (Materials to Avoid): Oxidizing agents
and drying oils.
Hazardous Polymerization: Thermal-oxidative degradation
of wood produces irritating and toxic fumes and gases,
including
CO,
aldehydes and
organic acids.
Hazardous Polymerization: _ will occur X will not
occur
Conditions to Avoid: Wood dust is extremely
combustible. Keep in a cool, dry place away from ignition
sources.
Section VI: Health Hazard Information
Effects of Overexposure: Avoid prolonged or repeated
breathing of wood dust in air. Repeated exposures (even
below 5 mg/m3)
to certain
wood
dusts (see
attached list) can produce allergic responses in sensitive
individuals. Avoid repeated or prolonged contact with
the skin, which will
also cause allergic
responses. If allergic responses, such as dermatitis,
asthma, or bronchitis develop, it may be4 necessary
to remove the
sensitive worker from further
exposure to wood dust (and also to wood based products
like turpentine and resin).
Probable Routes of Exposure: Inhalation, skin
Emergency
and First Aid Procedures:
Ingestion: N/A
Inhalation: Remove to fresh air.
If persistent irritation, severe coughing, breathing
difficulties or rash occur, get medical advice before
returning to work
with wood dust.
Eye Contact: Flush with water to remove dust particles
from the eye.
If irritation persists, get medical attention.
Skin Contact:
If a rash, or persistent irritation of dermatitis occurs,
get medical advice before returning to work where wood
dust is
present. If
a splinter enters
the skin, remove with tweezers.
Section VII: Toxicity
Data
Oral: Not Available
Dermal: The chronic effects of skin contact with wood
dust are not fully known and may vary from one wood
to another.
Inhalation: N/A
Carcinogenicity: Not listed as a carcinogen by IARG,
WTP, ACGIH, or OSHA
Other Pertinent Data: Certain species of woods,
(see attached list), are known to cause skin, eye and
URT
irritation
along with allergenic
responses
and asthma.
Exposure to wood dust has been statistically associated
with nasal cancer in British furniture workers. (CODATA
bulletin,
November
1978).
Section VIII: Special Protection Information
Personal Protective Equipment *
Protective Gloves:
Recommended to reduce skin contact, except where moving
machinery parts expose fingers to hazards.
Eye Protection:
Safety glasses
Respiratory Protection: (specific type)
Approved dust respirator, under dusty conditions.
*Protective equipment may be warranted at lower dust
exposure levels, depending on species of wood.
Other Protective Equipment:
Recommend the use of clean body-covering work clothing
to reduce exposure of skin to wood dust.
Ventilation:
Local Exhaust:
To meet TLV requirements. Due to the explosive potential
of wood dust when suspended in air, precautions should
be taken
to prevent
sparks
or other
ignition sources in ventilation equipment. Use of
total enclosed motors is recommended.

Section IX: Spill, Leak, and Disposal Procedures
Steps to be taken in case material is released or
spilled:
Sweep up or vacuum up spills for recovery or disposal,
avoiding dusting conditions. Provide good ventilation.
Place recovered
wood dust in
a covered metal container
for prompt disposal.
Waste Disposal Methods:
Dispose in a landfill or incinerate in accordance
with local, state and federal laws.
Clean Water Act Requirements: N/A
