IRON . Page 2 of 4 Inhalation: Remove to fresh air.Get medical attention for any breathing difficulty. Ingestion: Induce vomiting immediately as directed by medical personnel.Never give anything by mouth to an unconscious person.Get medical attention. Skin Contact: Wash exposed area with soap and water.Get medical advice if irritation develops. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes,lifting upper and lower eyelids occasionally.Get medical attention if irritation persists. 5.Fire Fighting Measures Fire: Moderate fire hazard in form of dust when exposed to heat or flame.Can react with water to liberate flammable hydrogen gas.Minimum ignition temperature, iron dust cloud:430C(805F).Ultrafine iron powder(ca.5 microns)is pyrophoric and can ignite spontaneously in air. Explosion: Moderate explosion hazard in the form of a dust when exposed to heat or flame. Fire Extinguishing Media: Use powdered graphite,powdered salt,or powdered limestone.DO NOT use water,carbon dioxide,or dry chemical. Special Information: In the event of a fire,wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. 6.Accidental Release Measures Ventilate area of leak or spill.Wear appropriate personal protective equipment as specified in Section 8.Spills:Pick up and place in a suitable container for reclamation or disposal,using a method that does not generate dust. 7.Handling and Storage Keep in a tightly closed container,stored in a cool,dry,ventilated area.Protect against physical damage.Avoid dust formation and control ignition sources. Containers of this material may be hazardous when empty since they retain product residues(dust,solids);observe all warnings and precautions listed for the product. 8.Exposure Controls/Personal Protection Airborne Exposure Limits: -OSHA Permissible Exposure Limit(PEL)- Iron oxide fume:10 mg/m3 -ACGIH Threshold Limit Value(TLV)- Iron oxide dust and fume(Fe203)as Fe:5 mg/m3(TWA);inhalable particulate:A4-Not classifiable as a human carcinogen. Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits.Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source,preventing dispersion of it into the general work area.Please refer to the ACGIH document,Industrial Ventilation,AManual of Recommended Practices,most recent edition,for details. Personal Respirators(NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible,a full facepiece particulate respirator(NIOSH type N100 filters)may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier,whichever is lowest.If oil particles(e.g.lubricants,cutting fluids.glycerine,etc.)are present,use a NIOSH type R or P filter.For emergencies or instances where the exposure levels are not known,use a full-facepiece positive-pressure,air-supplied respirator.WARNING:Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Maintain eye wash fountain and quick-drench facilities in work area.Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. 9.Physical and Chemical Properties Appearance: Gray crystalline chips.
