SECTION VI - HEALTH HAZARDS
EMERGENCY OVERVIEW: WARNING! Wood dust may form explosive mixture with air. Wood dusts may cause irritation to the eyes,
skin and respiratory tract.
ROUTES OF ENTRY: Dermal, Inhalation.
SIGNS AND SYMPTOMS OF ACUTE OVEREXPOSURE:
EYES: Contact with wood and/or wood dust may cause irritation to the eyes, regardless of treatment.
Symptoms can include irritation, redness, scratching of the cornea, and tearing.
SKIN: Prolonged contact with treated wood and/or treated wood dust, especially when freshly treated at the
plant, may cause irritation to the skin, and in extreme circumstances may cause chemical burns.
Abrasive handling or rubbing of the treated wood may increase skin irritation. Some wood species,
regardless of treatment, may cause dermatitis or allergic skin reactions in sensitized individuals.
INGESTION: Ingestion of wood or wood dust is unlikely. If ingestion does occur, gastrointestinal irritation may result
from both treated and untreated wood. Certain species of wood and their dusts may contain natural
toxins, which can also have adverse effects in humans.

Osmose MATERIAL SAFETY DATA SHEET
INHALATION: Wood dust, treated and untreated, is irritating to the nose, throat and lungs. Symptoms may include
nasal dryness, deposits or obstructions in the nasal passages, coughing, sneezing, dryness and
soreness of throat and sinuses, hoarseness, and wheezing. Prolonged or repeated inhalation of wood
dusts may cause respiratory irritation, recurrent bronchitis and prolonged colds. Some species may
cause allergic respiratory reactions with asthma-like symptoms in sensitized individuals. Prolonged
exposure to wood dusts by inhalation has been reported to be associated with nasal and paranasal
cancer.
CHRONIC OVEREXPOSURE: Prolonged exposure to wood dusts by inhalation has been reported to be associated with nasal
and paranasal cancer. Some wood species may cause dermatitis or allergic skin reactions in sensitized individuals.
CHEMICAL LISTED AS A CARCINOGEN OR POTENTIAL CARCINOGEN?: NatureWood treated wood and its components are
not listed as carcinogens by ACGIH, NIOSH, or IARC. ACGIH, NIOSH and IARC classify wood dust as a human carcinogen or
occupational carcinogen. This classification is based on an increased incidence of nasal and paranasal cancers in people
exposed to wood dusts.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Pre-existing eye, respiratory system and skin conditions.
TOXICITY: While acute toxicity testing has not been performed on the treated wood, the following information is available on
the chemical components that may have been used in the treating of Naturewood.

SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
US DOT SHIPPING DESCRIPTION: Not regulated.
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Avoid working with freshly treated wet wood. If not possible, wear long
sleeve shirt, long pants and gloves when working with freshly treated wet wood. Clothing should be removed and replaced if it becomes
wet due to contact with freshly treated wood. Avoid contact of wood and wood dusts with skin and eyes. Avoid inhalation of airborne
contaminants as a result of cutting or sawing treated wood. Do not eat, drink or smoke when handling this material or in areas where
dusts of this product are present.
OTHER PRECAUTIONS: Do not generate airborne dusts in the presence of an ignition source when sawing, cutting or grinding wood.
Wash hands after handling and before eating. Maintain good housekeeping procedures, such as sweeping regularly to avoid accumulation
of dusts. Store away from excessive heat, sparks and open flame.

Osmose MATERIAL SAFETY DATA SHEET
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: No containment procedures are needed as this product
cannot spill or leak the preservative. Keep away from sparks and flame. Wear appropriate protective equipment and clothing during
clean-up. Wet down accumulated dusts prior to sweeping or vacuuming in order to prevent explosion hazards. Sweep up or vacuum
small pieces and dusts and place in appropriate container for disposal. Gather larger pieces by an appropriate method. Avoid the
generation of airborne dusts during clean up. To avoid the inhalation of dusts during clean up, a dust mask is recommended.
WASTE DISPOSAL METHODS: Although no EPA Waste Numbers are applicable for this product's components, you must test your
waste to determine if it meets applicable definitions of hazardous waste and for State requirements. Dispose of waste material according
to local, State and Federal regulations.
SECTION VIII - CONTROL MEASURES
RESPIRATORY PROTECTION: Wear a dust mask when cutting, grinding or sanding wood and when cleaning up wood dust.
VENTILATION REQUIREMENTS: Provide good ventilation when cutting, grinding or sanding wood. Whenever possible these
operations should be performed outdoors.
PROTECTIVE GLOVES: Wear chemical resistant (rubber, neoprene or nitrile) gloves when handling freshly treated wood at the
treating plant. Otherwise, wear puncture resistant work gloves, such as leather.
EYE PROTECTION: Wear safety glasses with side shields when handling, cutting, sanding or grinding this material. Use a
face shield during processes that may generate excessive dusts and splinters.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Eye wash fountain is recommended.
WORK/HYGIENIC PRACTICES: Launder work clothes frequently.

SARA/SECTION 313 SUPPLIER NOTIFICATION:
This product contains a chemical which is either listed in Section 313 or is included in a chemical category listed in Section 313, and may
be present at or above de minimis concentrations. The following listed chemicals are present:
- Copper Oxide (CAS #1317-39-1) as a Copper Compound
For percent of copper oxide in the product, refer to the PERCENTAGE OF ACTIVE INGREDIENTS PER RETENTION LEVEL table in
Section II of the MSDS. According to 40 CFR 372.65(c)(5)(d), "Notifications are not required in the following instances: (1) If a mixture or
trade name product contains no toxic chemical in excess of the applicable de minimis concentration as specified in 372.38(a)." If you refer
to this section, it describes de minimis concentrations as "the toxic chemical is in a concentration in the mixture which is below 1 percent of
the mixture." As the copper oxide levels in NATUREWOOD are below 1% for 0.15 pcf, 0.25 pcf and 0.40 pcf, this Supplier Notification is
only applicable to wood treated to a 0.60 pcf retention.
