Exposure limit(s)
NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp) OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
Exposure effects
Blood pressure may be decreased following an iron overdose. Lethargy, restlessness or confusion may be seen early in the poisoning. Convulsions and coma may occur in later phases. Case reports of pregnant women who have received early aggressive treatment (decontamination and/or deferoxamine) have described good fetal outcomes.
   Ingestion
May cause irritation of the digestive tract. The toxicological properties of this substance have not been fully investigated. May cause blood abnormalities and hepatic cirrhosis.
   Inhalation
The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation.
   Skin
No information regarding skin irritation and other potential effects was found.
   Eyes
No information regarding eye irritation and other potential effects was found.

First aid
 
   Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
   Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
