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.

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.

Personal Protective Equipment
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin: Wear appropriate gloves to prevent skin exposure.
Clothing: 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.

Conditions to Avoid: Dust generation, moisture.
Incompatibilities with Other Materials: 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..
Hazardous Decomposition Products: None.
Hazardous Polymerization: Has not been reported.

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: No information found

Section 12 - Ecological Information

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.

Section 13 - Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification.
