Hazards and Protection.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect from physical damage and direct sunlight.
Wear protective gloves and clean body-covering clothing. Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn 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.
Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.
Light sensitive (darkens).
Oxides of sulfur and the contained metal.
Use any means suitable for extinguishing surrounding fire. 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.
Not considered to be a fire or explosion hazard.
ACGIH Threshold Limit Value (TLV): 1 mg/m3 (TWA) soluble iron salt as Fe
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.
Low toxicity in small quantities but larger dosages may cause nausea, vomiting, diarrhea, and black stool. Pink urine discoloration is a strong indicator of iron poisoning. Liver damage, coma, and death from iron poisoning has been reported.
Excessive inhalation of dust is irritating to the respiratory tract.
May cause irritation.
No adverse effects expected but dust may cause mechanical irritation.
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
Remove to fresh air. Get medical attention for any breathing difficulty.
Wash exposed area with soap and water. Get medical advice if irritation develops.
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.
