MATERIAL SAFETY DATA SHEET
lower dermal toxicity. Care should be taken to minimize the amount of Disodium Octaborate
Tetrahydrate released to the environment to avoid ecological effects.
POTENTIAL ECOLOGICAL EFFECTS:
Large amounts of Disodium Octaborate Tetrahydrate can be harmful to boron-sensitive plants and
other ecological systems.
POTENTIAL HEALTH EFFECTS
Routes of Exposure: Inhalation is the most significant route of exposure in occupational and
other settings. Dermal exposure is not usually a concern because Disodium Octaborate
Tetrahydrate is not absorbed through intact skin.
Inhalation: Occasional mild irritation of nose and throat may occur from inhalation of Disodium
Octaborate Tetrahydrate dusts at levels greater than 10 mg/m3.
Eye Contact: Disodium Octaborate Tetrahydrate is non-irritating to eyes in normal industrial use.
Skin Contact: Disodium Octaborate Tetrahydrate does not cause irritation to intact skin
Ingestion: Products containing Disodium Octaborate Tetrahydrate are not intended for ingestion.
Disodium Octaborate Tetrahydrate has a relatively low acute toxicity. Small amounts (e.g. a
teaspoonful) swallowed accidentally are not likely to cause effects; swallowing amounts larger than
that may cause gastrointestinal symptoms.
Cancer: Disodium Octaborate Tetrahydrate is not considered a carcinogen.
Reproductive: Long-term, high dose animal ingestion studies of similar inorganic borate
chemicals have demonstrated reproductive effects in male animals. A human study of
occupational exposure to borate dust showed no adverse effect to reproduction.
Developmental: Multiple high dose animal ingestion studies of similar inorganic borate chemicals
have demonstrated developmental effects in fetuses of pregnant animals, including fetal weight
loss.
Target Organs: No target organ has been identified in humans. Multiple high dose animal
ingestion studies of similar inorganic borate chemicals indicate the testes are the target organs in
male animals.
Signs and Symptoms of Exposure: Symptoms of accidental over-exposure to borate products
have been associated with ingestion or by absorption through large areas of damaged skin. These
may include nausea, vomiting, and diarrhea, with delayed effects of skin redness and peeling.
Refer to Section 11 for details on Toxicological Data.
SECTION 4 - FIRST AID MEASURES
Inhalation: No specific treatment is necessary since Disodium Octaborate Tetrahydrate is not
likely to be hazardous by inhalation. Prolonged exposure to dust levels in excess of regulatory
limits should always be avoided.
Eye Contact: Use eye wash fountain or fresh water to cleanse eye. If irritation persists for more
than 30 minutes, seek medical attention.
Skin Contact: No treatment necessary because non-irritating.
Ingestion: Swallowing less than one teaspoon will cause no harm to healthy adults. If larger
amounts are swallowed, give two glasses of water to drink and seek medical attention.
NOTE TO PHYSICIANS: Observation only is required for adult ingestion of a few grams of
Disodium Octaborate Tetrahydrate. For ingestion in excess of larger amounts, maintain adequate

kidney function and force fluids. Gastric lavage is recommended for symptomatic patients only.
Hemodialysis should be reserved for massive acute ingestion or patients with renal failure. Boron
analyses of urine or blood are only useful for documenting exposure and should not be used to
evaluate severity of poisoning or to guide treatment.
SECTION 5 - FIRE FIGHTING MEASURES
General Hazard: None, because Disodium Octaborate Tetrahydrate is not flammable,
combustible or explosive. The product itself is a flame retardant.
Extinguishing Media: Any fire extinguishing media may be used on nearby fires.
Flammability Classification (29 CFR 1910, 1200): Non-flammable solid.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
General: Disodium Octaborate Tetrahydrate is a water-soluble white powder that may cause
damage to trees or vegetation by root absorption. (Refer to Ecological information for specific
information)
Land Spill: Vacuum, shovel or sweep up Disodium Octaborate Tetrahydrate and place in
containers for disposal in accordance with applicable local regulations. Avoid contamination of
water bodies during clean up and disposal. No personal protective equipment is needed to clean
up land spills
Water Spill: Disodium Octaborate Tetrahydrate will cause localized contamination of surrounding
waters depending on the quantity dissolved in these waters. At high concentrations some damage
to local vegetation, fish and other aquatic life may be expected.
Disodium Octaborate Tetrahydrate is a non-hazardous waste when spilled or disposed of, as
defined in the Resource Conservation and Recovery Act (RCRA) regulations (40 CFR 261). (Refer
to Regulatory Information for additional references and information regarding EPA and California
regulations.)
SECTION 7 - HANDLING AND STORAGE
Storage Temperature: Ambient
Storage Pressure: Atmospheric
Special Sensitivity: Moisture (Caking)
General: No special handling precautions are required, but dry, indoor storage is recommended.
To maintain package integrity and to minimize caking of the product, bags should be handed on a
"first-in first-out" basis. Good housekeeping procedures should be followed to minimize dust
generation and accumulation.
SECTION 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls: Use local exhaust ventilation to keep airborne concentrations of Disodium
Octaborate Tetrahydrate dust below permissible exposure levels.
Personal Protection: Where airborne concentrations are expected to exceed exposure limits,
NIOSH/MSHA certified respirators must be used. Eye goggles and gloves are not required for
normal industrial exposures, but may be warranted if environment is excessively dusty.

SECTION 11 - TOXICOLOGICAL INFORMATION
Ingestion (acute oral toxicity): Low acute oral toxicity; LD50 of Disodium Octaborate
Tetrahydrate in rats is 2500 mg/kg of body weight.
Skin (acute dermal toxicity): Low acute dermal toxicity; LD50 of Disodium Octaborate Tetrahydrate
in rabbits is greater than 2000 mg/kg of body weight. Disodium Octaborate Tetrahydrate is not
absorbed through intact skin.
Primary Skin Irritation Index: 0.5, Disodium Octaborate Tetrahydrate is non-corrosive
Eye: Draize test in rabbits produced mild eye irritation effects. Many years of occupational
exposure history reflects no indication of human eye injury from exposure to Disodium Octaborate
Tetrahydrate.
NOTE: Disodium Octaborate Tetrahydrate is chemically and toxicologically related to boric acid;
the majority of the borate chronic toxicology studies were conducted using boric acid. Disodium
Octaborate Tetrahydrate is converted to boric acid in biological systems. The boric acid data
discussed in this section can be converted to Disodium Octaborate Tetrahydrate equivalent data
by dividing by a factor of 1.1992.
Inhalation: Human epidemiological studies show no increase in pulmonary disease in
occupational populations with chronic exposures to boric acid dust and sodium borate dust.
Carcinogenicity: A Technical Report issued by the National Toxicology Program showed "no
evidence of carcinogenicity" from a full 2-year bioassay on boric acid in mice at feed doses of 2500
and 5000 ppm in the diet. No mutagenic activity was observed for boric acid in a recent battery of
file:///C|/Documents%20and%20Settings/Jim%20R...roe/My%20Documents/MSDS's/Board%20Defense.htm (4 of 8) [1/21/2006 3:15:07 PM]
MATERIAL SAFETY DATA SHEET
four short-term mutagenicity assays.
Reproductive / Developmental Toxicity: Animal studies indicate Boric Acid reduces or inhibits
sperm production, causes testicular atrophy, and, when given to pregnant animals during
gestation, may cause developmental changes. These feed studies were conducted under chronic
exposure conditions leading to doses many times in excess of those that could occur through
inhalation of dust in occupational settings.
Reproductive Toxicity (Fertility): Dietary boric acid levels of 6,700 ppm in chronic feeding
studies in rats and dogs produced testicular atrophy, while dogs and rats receiving 2000 ppm did
not develop testicular changes (1Weir, Fisher, 1972). In chronic feeding studies of mice on diets
containing 5000 ppm (550 mg/kg/d) boric acid, testicular atrophy was present while mice fed 2500
ppm (275 mg/kg/d) boric acid showed no significant increase in testicular atrophy (2NTP, 1987). In
another boric acid chronic study, in mice given 4500 ppm (636 mg/kg/d), degeneration of
seminiferous tubules was present together with a reduction of germ cells, while at 1000 ppm (152
mg/kg/d) no effect was seen (3Fail et al., 1991). In a reproduction study on rats, 2000 ppm of
dietary boric acid had no adverse effect on lactation, litter size, weight and appearance (1Weir,
Fisher, 1972). In a continuous breeding study in mice there was reduction in fertility rates for
males receiving 4500 ppm (636 mg/kg/d) boric acid, but not for females receiving 4500 ppm boric
acid (3Fail et al., 1991)
Developmental Toxicity: Boric acid at dietary levels of 1000 ppm (78 mg/kg/d) administered to
pregnant female rats throughout gestation caused a slight reduction in fetal weight, but was
considered to be close to the LOAEL. Doses of 2000 ppm (163 mg/kg/d) and above caused fetal
malformations and maternal toxicity. In mice the no effect level for fetal weight reduction and
maternal toxicity was 1000 ppm (248 mg/kg/d) boric acid. Fetal weight loss was noted at dietary
boric acid levels of 2000 ppm (452 mg/kg/d) and above. Malformations (agenesis or shortening of
the thirteenth rib) were seen at 4000 ppm (1003 mg/kg/d), (4Heindel et al., 1992).

SECTION 12 - ECOLOGICAL INFORMATION
ECOTOXICITY DATA:
Phytotoxicity: Although boron is an essential micronutrient for healthy growth of boron-sensitive
plants, it can be harmful to plants in higher quantities. Plants and trees can easily be exposed by
root absorption to toxic levels of boron in the form of water-soluble borate leached into nearby soil
or waters. Care should be taken to minimize the amount of borate product released to the
environment.
Fish Toxicity: Boron naturally occurs in sea water at an average concentration of 5 mg B/liter. In
laboratory studies the acute toxicity (96-hr LC50) for under-yearling Coho salmon (Opchorhynchus
kisutch) in sea water was determined as 40 mg B/L (added as sodium metaborate). Boron
concentrations in fresh surface waters are generally less than 1 mg B/L. Laboratory studies on the

toxicity of freshwater fish were determined using early life (embryo-larval) stages in natural water
and Boric Acid as a test substance. The results were:
Rainbow Trout (S. gairdneri)
24-day LC50=150.0 mb B/L
36-day NOEC鈥OEC=0.75-1 mg B/L
Goldfish (Carassius auratus)
7-day NOEC鈥OEC=26.50 mg B/L
3-day LC50=178 mg B/L
Invertebrate Toxicity: The acute toxicity (48-hour LC50) to Daphnids (Daphnia magna Straus) in
natural water is reported to be 133 mg B/L (added as boric acid). Estimated chronic toxicity (21-
day NOEC鈥OEC) values of 6-13 mg B/L (added as boric acid) have also been reported.
ENVIRONMENTAL FATE DATA:
Persistence/Degradation: Boron is naturally occurring and ubiquitous in the environment.
Disodium Octaborate Tetrahydrate decomposes in the environment to natural borate.
Soil Mobility: The product is soluble in water and is leachable through normal soil.
NOTE: Boron (B) is the element in Disodium Octaborate Tetrahydrate which is used to
characterize borate product ecological effects. To convert Disodium Octaborate Tetrahydrate data
to Boron (B), multiply by 0.2096.
