IV      FIRE AND EXPLOSION H AZARDS DATA



Flash Point: N/A                                                               Method U sed: Non-flam ma ble

Explosive Lim its: Lower: N/A       Upper: N/A



Extingu ishing Media: Use suitable extinguishing media for surrounding materials and type of fire.

Special Fire Fighting Procedures: Wear full face, and self-contained breathing apparatus with full protective clothing to prevent

contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.

Unusual Fire and Explosion Hazards: Aluminum boride may em it toxic fumes of boron and barium if involved in a fire. Contact

with acids m ay em it flamma ble hydroge n gas.





V       HEALTH H AZARD DA TA



Effects of Exposure:



        To the best of our knowledge the chemical, physical and toxicological properties of aluminum boride have not been

thoroughly investigated and recorded.



         Aluminum compounds have many industrial uses and are commonly found in industry. Many of these materials are active

chem ically and thus exh ibit dange rous tox ic and reactive prop erties.



         Boron comp ounds are very toxic and therefore considered an industrial poison. Boron is one of a group of elements, such as

Pb, Mn, As, which effects the central nervous system. Boron poisoning causes depression of the circulation, persistent vomiting and

diarrhea, followed by profound shock and comma. The temperature becomes subnormal and a scarlatina form rash may cover the

entire body (Sax, Dan gerous Prope rties of Industrial Materials, eighth ed.).

Acute E ffects:



Inhalation: May cause mild respiratory irritation.

Ingestion: No acute health effects recorded.

Skin : May cause abrasive irritation.

Eye: May cause abrasive irritation.



Chro nic Effects:



Inhalation: May cause pulmonary granu lomas.

Ingestion: May be im plicated in A lzheim ers.

Skin : No chronic health effects recorded.

Eye: No chronic health effects recorded.



Routes of Entry: Inhalation, Skin, Eyes, Ingestion

Target Organs: May affect the respiratory and central nervous system.



Medical Conditions Generally Aggravated by Exposure: Pre-existing resp iratory disord ers.

Carcino genicity: NTP: No      IARC M onographs: No             OSH A Regulated: No



EMERG ENCY AND FIRST AID PROCEDURES:



INHALATION: Rem ove to fresh air. Keep w arm and quiet, give o xyg en if breathing is d ifficult an d seek m edica l attention.

INGESTION: If conscious, give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never give anything by

mouth or induce vomiting on an unconscious person.

SK IN: Remove contaminated clothing from affected area, brush material off skin, wash affected area with mild soap and water, seek

me dical attention if sym ptom s persist.

EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms

persist.

IX       ADDITIONAL COM MENTS



Hazard Label Information: Store in cool, dry area. Store in tightly sealed container. Wash thoroughly after handling.



Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure at low levels.

Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and

smok ing. Do not blow dust off clothing with comp ressed air.
