Hazards and Protection.
Store dry at ambient temperatures.
Follow normal laboratory safety guidelines.
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Niosh approved respirator for dusts, mists and fumes.
Handle as normal solid waste.
Stable at normal temperatures and pressures.
Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Noncombustible, except as powder. Hematite, red
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.
May cause irriation.
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.
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse.
Diagnosis of iron intraocular foreign body can be done by x-ray, by computerized tomography, by establishing that the foreign body can be moved with a magnet, and by electroretinogram. Magnetic resonance imaging is not recommended as movement of the foreign body may result.
