acid can be used in an identical manner, is chemically very similar to and slightly more toxic than comparable concentrations and
exposures to disodium octaborate tetrahydrate. Boric acid is hazardous under the OSHA Hazard Communication Standard based on
animal chronic toxicity studies.
HAZARD IDENTIFICATION
EMERGENCY OVERVIEW:
FIBER-LITE PLUS Insulation is a gray, odorless wood fiber Insulation material. The product is not flammable, combustible, or
explosive, and it presents no unusual hazard if involved in a fire. FIBER-LITE PLUS Insulation presents little or no hazard (to
humans) and has low acute oral and dermal toxicities. Care should be taken to minimize the amount of FIBER-LITE PLUS Insulation
released to the environment to avoid ecological effects.
POTENTIAL ECOLOGICAL EFFECTS:
Large amounts of FIBER-LITE PLUS Insulation 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 FIBER-LITE PLUS Insulation is not absorbed through intact skin.
Inhalation: Occasional mild irritation of nose and throat may occur from inhalation of FIBER-LITE PLUS Insulation dusts at levels
greater than 10 mg/m3.
Eye Contact: FIBER-LITE PLUS Insulation is non-irritating to eyes in normal industrial use.
Skin Contact: FIBER-LITE PLUS Insulation does not cause irritation to intact skin
Ingestion: FIBER-LITE PLUS Insulation is not intended for ingestion. FIBER-LITE PLUS Insulation has a relatively low acute
toxicity. Small amounts (e.g. 3 teaspoonfuls) swallowed accidentally are not likely to cause effects; swallowing amounts larger than
that may cause gastrointestinal symptoms.
Cancer: FIBER-LITE PLUS Insulation is not considered a carcinogen.
Reproductive: Long-term, high dose animal ingestion studies of similar inorganic borate chemicals at significantly higher
concentrations have demonstrated reproductive effects in male animals. A human study of occupational exposure to borate dust
showed no adverse effect to reproduction.
Developmental: High dose animal ingestion studies of similar inorganic borate chemicals at significantly higher concentrations have
demonstrated developmental effects in fetuses of pregnant animals, including fetal weight loss.
Target Organs: No target organ has been identified in humans. High dose animal ingestion studies of similar inorganic borate
chemicals at significantly higher concentrations 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 Toxicology Information Section for details on Toxicological Data.

FIRST AID MEASURES
Inhalation: No specific treatment is necessary since FIBER-LITE PLUS Insulation 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 FIBER-LITE PLUS Insulation. 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.

FIRE FIGHTING MEASURES

TOXICOLOGICAL INFORMATION
NOTE: FIBER-LITE PLUS Insulation contains 13.76% boric acid, and 86.24% inert wood fiber with conditioners. The boric acid
data discussed in this section relates to 100% pure boric acid.
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 (636mg/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 NOAEL. 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 (ageneses or shortening of the thirteenth rib) were seen at 4000 ppm (1003 mg/kg/d), (4Heindel et al.,
1992).

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 (OPest Controlhorhynchus kisutch) in sea water was determined as 40 mg B/L
Fiberlite Technologies, Inc. - FIBER-LITE PLUS Insulation ??
(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. Boric acid decomposes in the
environment to natural borate.
Soil Mobility: The boric acid additive in FIBER-LITE PLUS Insulation is soluble in water and is leachable through normal soil.
NOTE: Boron (B) is the element in FIBER-LITE PLUS Insulation which is used to characterize borate ecological effects. To convert
FIBER-LITE PLUS Insulation data to Boron (B), multiply by 0.0235.

DISPOSAL CONSIDERATIONS
Disposal Guidance: Small quantities of FIBER-LITE PLUS Insulation 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
