V HEALTH H AZARD DA TA
Health Hazards (Acute and Ch ronic):
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 m aterials are active chemically 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 pro found sho ck and com a. The tempe rature becom es subnorm al and a scarlatina form rash may co ver the entire
body (Sax , Dangerou s Properties of Industrial Materials, eighth ed.).
Acute E ffects:
Inhalation: May cause respiratory irritation and boron poisoning.
Ingestion: May cause gastrointestinal irritation and boron poisoning.
Skin : May cause mild irritation.
Eye: May cause mild irritation.
Chro nic Effects:
Inhalation: May cause pulmonary granu lomas.
Ingestion: May affect the central nervous system.
Skin : May cause dermatitis.
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 in 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.
EYES: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
persist.
