Safety information
First Aid：
EYES or SKIN: flush with water. (USCG, 1999)
Fire Hazards：
Special Hazards of Combustion Products: Irritating and toxic ammonia and oxides of nitrogen may form in fires. (USCG, 1999)
Fire Potential：
Not flammable /Ferrous ammonium sulfate hexahydrate/
Health Hazards：
Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact. (USCG, 1999)
OSHA Standards：
Vacated 1989 OSHA PEL TWA 1 mg/cu m is still enforced in some states. /Iron salts (soluble, as Fe)/
Reactive Group：
Salts, Acidic
Adverse Effects：
Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.
Cleanup Methods：
Environmental considerations: Land spill: Big a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover soldis with a plastic sheet to prevent dissolving in rain or fire fighting water.
Hazards Summary：
A skin and eye irritant; [CAMEO] LD50 (rats) = 0.5-5 g/kg; Could cause iron poisoning and liver damage if ingested; [MSDSonline] See Iron, soluble compounds.
Primary Hazards：
Not Classified
Disposal Methods：
The following wastewater treatment technologies have been investigated for iron (Fe+2): Concentration process: Biological treatment. /Iron (Fe+2)/
Reactivity Profile：
FERROUS AMMONIUM SULFATE releases irritating and toxic ammonia and oxides of nitrogen if burned (USCG, 1999).
Storage Conditions：

NIOSH Recommendations：
Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 1 mg/cu m. /Iron salts (soluble, as Fe)/
Regulatory Information：
New Zealand EPA Inventory of Chemical Status: Sulfuric acid, ammonium iron(II) salt: Does not have an individual approval but may be used under an appropriate group standard
Air and Water Reactions：
Soluble in water that forms weakly acidic solutions. Deliquesces in air.
Human Toxicity Excerpts：
/HUMAN EXPOSURE STUDIES/ Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact.
Fire Fighting Procedures：
If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Other Safety Information：
Chemical Assessment: IMAP assessments - Sulfuric acid, ammonium iron(2+) salt (2:2:1): Human health tier I assessment
Non-Human Toxicity Values：
LD50 Rat oral 3,250 mg/kg bw /Hexahydrate/
Toxic Combustion Products：
Irritating and toxic ammonia and oxides of nitrogen may form in fires. /Ferrous ammonium sulfate hexahydrate/
Non-Human Toxicity Excerpts：
/ALTERNATIVE IN VITRO TESTS/ The effect of vitamin E deficiency on brain mitochondrial oxidative phosphorylation was studied using brain mitochondria isolated from control and vitamin E-deficient rats (13 months of deficiency) after exposure to iron, an inducer of oxidative stress. Mitochondria were treated with iron (2 to 50 microM) added as ferrous ammonium sulfate. Rates of state 3 and state 4 respiration, respiratory control ratios, and /the ratio of ADP molecules phosphorylated to oxygen atoms reduced/ (ADP/O) were not affected by vitamin E deficiency alone. However, iron uncoupled oxidative phosphorylation in vitamin E deficient mitochondria, but not in controls. In vitamin E deficient mitochondria, iron decreased ADP/O ratios and markedly stimulated state 4 respiration; iron had...
