Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat, light, and water. Material will absorb moisture from the atmosphere.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Dust mask; goggles or face shield; protective gloves.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Allow to aerate. Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Slowly oxidizes in air. Ferrous ammonium sulfate hexahydrate.
Incompatible with sulfuric acid.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)
Containers may explode when heated.
Irritating and toxic ammonia and oxides of nitrogen may form in fires.
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.
Nausea, vomiting, diarrhea and gastrointestinal hemorrhage may develop.
Noncardiogenic pulmonary edema may develop with severe intoxication.
Severe thermal burn with ferrous sulfate slurry has caused classical symptoms of ingested iron poisoning.
Irritants may cause swelling, redness and pain at any site, especially at mucous membranes. The mouth, nose, and eyes are susceptible to these effects.
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes.
Immediately flush with running water for at least 20 minutes.
