EMERGENCY OVERVIEW
Appearance: white powder.
Warning! Causes eye, skin, and respiratory tract
irritation. May impair fertility. May cause harm to the unborn child.
Hygroscopic (absorbs moisture from the air).
Target Organs: Respiratory system, eyes,
reproductive system, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause erythema (redness) and
exfoliation.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
Dust is irritating to the respiratory tract.
Chronic:
May cause kidney injury. May cause reproductive and fetal effects.
Repeated ingestion of small amounts may cause mucous membrane
dryness, hair loss, swelling around eyes and irritability.
Section 4 - First Aid Measures
|
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally
lifting the upper and lower eyelids. Get medical aid.
Skin:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
Ingestion:
Get medical aid. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
|
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Boric oxide
is not flammable, combustible or explosive. The product is itself a
flame retardant.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
Flash Point: Not available.
Autoignition Temperature: Not available.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 0; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Avoid breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.

Acids, Reaction with strong reducing agents, such as metal hydrides
or alkali metals, will generate hydrogen gas, which could lead to an
explosion., Reacts violently on contact with bromine pentafluoride.
Slowly reacts with water to release heat( (75.94 kJ/mol) and form
boric acid..

Carcinogenicity:
CAS# 1303-86-2:
Not listed by ACGIH, IARC, NTP, or CA Prop 65.
Epidemiology:
Human epidemiological studies show no increase in pulmonary
disease in occupational populations with chronic exposure
to boric acid dust.
Teratogenicity:
Developmental effects were observed in mice, rats and
rabbits after oral adminstration of boric acid. However,
these effects were considered secondary to maternal
toxicity (increased liver and kidney weight).
Reproductive Effects:
Animal ingestion studies in several species, at high doses,
have demostrated effects on fertility and testes. The doses
administered were many times in excess of those to which
humans would normally be exposed.A human study of
occupational exposure to borate dust showed no adverse
reproductive effects.
Mutagenicity:
No information found
Neurotoxicity:

Ecotoxicity:
Daphnia: Daphnia: 133 mg B/L; 48-Hr.; LC 50Fish: Rainbow trout:
150 mg B/L; 24-Day; LC 50Fish: Goldfish: 46 mg B/L; 7-Day; LC
50Fish: Goldfish: 178 mg B/L; 3-Day; LC 50
No data available.
Environmental:
This chemical will hydrolyze slowly in aqueous solution to form boric
acid. It has a low potential to affect aquatic organisms.
Physical:
Boron is naturally occuring and ubiquitous in the environment. Boric
oxide decomposes in the environment to natural borate.
Other:
Large amounts of Boric Oxide can be harmful to plants and vegetation
by root absorption.
