SECTION 2 - COMPOSITION/INFORMATION
ON INGREDIENTS OSHA HAZARDS
This
product contains greater than 99 percent (%) Disodium Octaborate Tetrahydrate
(Na2B8O13•4H2O) CAS No.
12280-03-4. Disodium Octaborate
Tetrahydrate is hazardous under the OSHA Hazard Communication Standard based on
animal chronic toxicity studies of similar inorganic borate chemicals.
SECTION 3 - HAZARD IDENTIFICATION
EMERGENCY
OVERVIEW
Disodium
Octaborate Tetrahydrate is a white, odorless, powdered substance that is not
flammable, combustible, or explosive, and it presents no unusual hazard if
involved in a fire. Disodium Octaborate
Tetrahydrate presents little or no hazard (to humans) and has low acute oral
and even 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.
Occupational Exposure Limits: Disodium Octaborate
Tetrahydrate is listed/regulated by OSHA, Cal OSHA and ACGIH as
"Particulate Not Otherwise Classified" or "Nuisance Dust".
OSHA:
PEL* 15
mg/m3 total dust and 5 mg/m3 respirable dust

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
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•LOEC=0.75-1 mg B/L
Goldfish
(Carassius auratus)
7-day
NOEC•LOEC=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•LOEC) 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.
SECTION 13 - DISPOSAL CONSIDERATIONS
Disposal Guidance: Small quantities of
Disodium Octaborate Tetrahydrate can usually be disposed of at Municipal
Landfill sites. No special disposal
treatment is required, but refer to state and local regulations for applicable
site-specific requirements. Tonnage
quantities of product are not recommended to be sent to landfills. Such product should, if possible, be re-used
for an appropriate application.
RCRA (40 CFR 261): Disodium Octaborate
Tetrahydrate is not listed under any sections of the Federal Resource
