HEALTH HAZARD INFORMATION

 

 

The desiccant properties of Activated Alumina may cause irritation to the eyes and 
upper respiratory tract. 
 
Alumina is a low health risk by inhalation. Alumina should be treated as a nuisance 
dust, as specified by the American Conference of Governmental Industrial 
Hygienists (ACGIH). 
 

According to AIHA Hygienic Guide, Alumina: 

Toxicity by ingestion: 

None expected 

Skin and eyes: 

Not an irritant
