Oxides of carbon.
Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment. extinguish with regular foam, water fog, carbon dioxide or sand.
Dusts can form explosive mixtures in air.
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.
Dust can cause eye irritation. Symptoms include stinging, tearing, redness, and swelling of eyes.
First aid is not normally required. If symptoms develop, seek medical attention.
