Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.

Hazards Identification

Inhalation

Noncardiogenic pulmonary edema may develop with severe intoxication.

Skin

Severe thermal burn with ferrous sulfate slurry has caused classical symptoms of ingested iron poisoning.

Eyes

Dust can cause eye irritation. Symptoms include stinging, tearing, redness, and swelling of eyes.

Ingestion

Nausea, vomiting, diarrhea and gastrointestinal hemorrhage may develop.

Hazards

Dusts can form explosive mixtures in air.

Exposure Controls/Personal Protection

Personal Protection

Wear safety glasses in compliance with OSHA regulations. Wear resistant gloves such as latex.

3M Dust respirator No. 8710 or 9900 is recommended or a NIOSH/MSHA jointly approved dust respirator.

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.

Fire Fighting Measures

Fire Fighting

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.

Accidental Release Measures

Small spills/leaks

Small Spill-Sweep up material for disposal or recovery. Large Spill-Shovel material into containers. Thoroughly sweep area of spill to clean up any residual material.

Stability

Stable at normal temperatures and pressures.

Decomposition

Oxides of carbon.
