Safety and Handling

【Skin, Eye, and Respiratory Irritations】
If inhaled, iron is a local irritant to the lung and gastrointestinal tract. /Iron compounds/
【Cleanup Methods】
Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
【Fire Fighting Procedures】
In case of fire in the surroundings: all extinguishing agents allowed.
【Fire Potential】
Ferrous oxide is spontaneously flammable in air.
The oxide (prepared at 300 deg C) burns in air above 200 deg C, while the finely divided oxide prepared by reduction may be pyrophoric at ambient temperature. That prepared by thermal decomposition under vacuum of iron(II)oxalate is also pyrophoric.
【Reactivities and Incompatibilities】
Fluorine does not act in the cold on ferrous oxide, but with gentle heat a reaction sets in with incandescence.
When ferrous oxide, prepared at 300 deg C, is heated in sulfur dioxide, the mass becomes incandescent.
Easily oxidized by air. It is a strong base and readily absorbed /carbon dioxide/.
The oxide incandesces when heated in sulfur dioxide.
Ignites when heated in air above 200 deg C
Hazardous reaction with nitric acid (powdered oxide); hydrogen peroxide; sulfur dioxide and heat.
When pyrophoric iron oxide is gently warmed with nitric acid, the oxide becomes incandescent.
【Other Preventative Measures】
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
All ... /iron/ preparations should be kept in child-proof bottles. /Iron preparations/
【Protective Equipment and Clothing】
If inhaled, iron is a local irritant to the lung and gastrointestinal tract. /Iron compounds/
【Specification】

?The Iron oxide, spent?(Fe3O4/FeO) is a two-step thermochemical process used for hydrogen production. It is a?flammable solid, should be kept away from sparks and flames.

【Report】

Reported in EPA TSCA Inventory.

【Disposal Methods】
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
