Exposure effects
Aluminum compounds have many commercial uses and are commonly found in industry. Many of these materials are active chemically and thus exhibit dangerous toxic and reactive properties. Inhalation of fine aluminum oxide particles is associated with Shaver's disease. Most antimony compounds are poisons by ingestion, inhalation, and intraperitoneal routes. Locally antimony compounds irritate the skin and mucous membranes
   Ingestion
Acute: May cause nausea, vomiting, diarrhea and cramps. Chronic: May be implicated in Alzheimer's disease.
   Inhalation
Acute: Inhaltion of dust or powder may cause irritation to the respiratory system, nose throat and mouth. Chronic: Inhalation of finely divided powder may cause pulmonary fibrosis.
   Skin
Antimony is a primary irritant.
   Eyes
Dust and powder may cause irritation.

First aid
 
   Ingestion
Give 1-2 glasses of milk or water and induce vomiting; seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.
   Inhalation
Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention.
   Skin
Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention.
   Eyes
Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
