Health Effects:
The following health effects refer to the sawdust from non treated Australian hardwood, based on current
research and knowledge.
Acute Health Effects:
Swallowed: Unlikely under normal conditions. Swallowing sawdust may cause
abdominal discomfort.
Eye: Wood dust is irritating to the eyes resulting in redness and watering.
Skin: Skin contact with sawdust may cause skin irritation.
Inhaled: Inhalation of sawdust may be irritating to the nose, throat and lungs.
Chronic Health Effects:
Chronic: Repeated inhalation of wood dust may increase the risk of nasal cavity
cancer. Exposure to wood dust is associated with respiratory and skin
sensitisation resulting in asthma and dermatitis respectively. Repeated
contact with green timber may cause dermatitis. In 1987, the International
Agency for Research on Cancer (IARC) evaluated several wood industries
as follows:

Treated Hardwood March 2007
Carpentry and joinery Group 2B 鈥? possible carcinogenic to humans
Furniture and cabinet making Group 1 鈥? carcinogenic to humans
Lumber and sawmill industries Group 3 鈥? not classifiable
Pulp and paper manufacture Group 3 鈥? not classifiable
However, if the work practices noted in this MSDS are followed, and
exposure to airborne dusts are kept low, no acute or chronic health effects
are anticipated.
First Aid: If poisoning occurs, contact a doctor or Poisons Information Centre.
Swallowed: Give water to drink. Seek medical attention if any abdominal discomfort.
Eyes: Flush thoroughly with water for at least 15 minutes. If irritation persists
seek medical attention.
Skin: Wash thoroughly with mild soap and water. Remove clothing if
contaminated with sawdust.
Inhaled: Leave the dusty area.
Advice to Doctor:
Advice to Doctor: Treat symptomatically.
Exposure standards: Worksafe Australia Exposure Standard. There is no specific Exposure
Standard for Australian Hardwood, but the following should apply.
Name TWA STEL
mg/m3 ppm mg/m3 ppm
Wood dust measured as inspirable particulate 1.0 - - -
(certain hardwoods such as beech & oak)
sen 鈥? sensitising to skin and respiratory tract
Hyne Timber Recommendation: Keep exposure as low as practicable with the aim of maintaining
inspirable wood dust levels below 1.0 mg/m3 TWA.
Engineering controls: All work must be carried out in such a way as to minimise exposure to
sawdust. Measures should be taken to eliminate the build up of static
electricity.
Respiratory Protection: If engineering controls are not practical then respiratory devices may need
to be worn. Avoid breathing sawdust from non treated Australian
hardwood. Wear a P1 or P2 respirator suitable for particulate and
conforming with Australian Standards AS/NZS 1715 and AS/NZS 1716
when exposed to dust. These standards should be followed in the
selection, fit-testing, use, storage and maintenance of the respirators.
Skin Protection: Wear protective gloves (AS/NZS 2161.1), loose comfortable clothing and
boots. Long sleeved shirts and long trousers are recommended if skin
irritation occurs. Wash skin with mild soap and water after working with

Eye protection: Non-fogging goggles or safety glasses (AS/NZS 1337) should be worn if
there is a risk of sawdust getting into the eyes.
Flammability: Not flammable under normal conditions of use, but is combustible and
will help sustain a fire.
Storage: Store in a well ventilated area away from sources of heat, flame, sparks or
other contamination.
While no special transport requirements are recommended, it should be
noted that this product can spontaneously combust. Avoid confining this
product for long periods of time in poorly ventilated containers.

Spills and disposal: Waste material should be placed in containers and disposed of at
approved landfill sites or incinerated in accordance with local authority
guidelines. Sawdust from non treated Australian hardwood can be burnt
in open fires, stoves, fireplaces and residential boilers.
Fire/explosion hazard: Sawdust will help sustain a fire and the dust may form an explosive
mixture with air. Avoid sparks, the build up of static electricity and
sources of ignition in all electrical equipment and dust extraction
equipment.
Fire Fighting: In a fire, use water jets to extinguish flames.
Suitable extinguishing media: If material is involved in a fire use water, fog (or if unavailable fine water
spray), foam, dry agent (carbon dioxide, dry chemical powder).
Smoking: Hyne Timber recommends that all storage and work areas should be
smoking-free areas.
Toxicology: None allocated.
