Composition / Information on Ingredients

Chemical Name: Iron
Percentage: 98.0% – 99.9% by weight
Impurities: Trace elements may include carbon, hydrogen, sulfur, oxygen, nitrogen (levels are usually less than 1%)
CAS Number: 7439-89-6

First Aid Measures

Inhalation: Move to fresh air. Seek medical help if symptoms persist, such as coughing or shortness of breath.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if easy to do. Continue rinsing. Seek medical attention if irritation results.
Skin Contact: Wash area with soap and water. Remove contaminated clothing and launder before reuse.
Ingestion: Rinse mouth. Drink water to dilute. If feeling unwell, contact a physician or poison control center.
Most Important Symptoms: Mechanical irritation possible for eyes, skin, and respiratory tract. Symptoms may include redness, itching, and coughing.

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical powder, sand, or foam. Water may be used for larger fires involving bulk materials away from sensitive equipment.
Inappropriate Extinguishing Media: Do not use water jets directly on burning metal powder.
Unusual Fire Hazards: Iron powder can react with heat and sparks, generating flammable iron oxide dust. Severe heat may release toxic metal fumes.
Protective Equipment: Use full protective gear and self-contained breathing apparatus. Firefighters should isolate area and evacuate if significant quantities are involved.

Accidental Release Measures

Personal Precautions: Wear dust masks, gloves, and eye protection. Prevent dust formation and inhalation.
Environmental Precautions: Prevent run-off or spillage into drains, surface water, and soil.
Spill Cleanup Methods: Use non-sparking tools. Sweep up material and transfer to closed, labeled containers. Avoid creating airborne particles. Wash area after clean-up.

Handling and Storage

Handling: Use in a well-ventilated area. Keep containers tightly closed. Use grounding and bonding to prevent static discharge.
Hygiene Practices: Do not eat, drink, or smoke while using. Wash hands and face thoroughly after handling.
Storage Conditions: Store in cool, dry, well-ventilated locations. Keep away from acids, oxidizers, and moisture. Do not store near sources of ignition or strong reducing agents.
Container Requirements: Keep in original or compatible, labeled containers. Prevent exposure to air or humid environments to avoid rust.

Exposure Controls and Personal Protection

Workplace Exposure Limits: OSHA PEL: 10 mg/m³ (as iron oxide fume), ACGIH TLV: 5 mg/m³ (respirable fraction)
Engineering Controls: Use local exhaust ventilation or process enclosure to limit airborne dust.
Respiratory Protection: Use approved particulate respirator if dust formation is possible.
Eye Protection: Safety glasses or chemical goggles
Skin Protection: Wear gloves, long sleeves, and protective footwear.
Work Practice Controls: Avoid generating dust. Handle in areas with good air exchange. Wash thoroughly after use.

Conditions to Avoid: Moisture, heat, open flame, static discharge
Hazardous Decomposition: Iron oxides if burned or heated strongly
Polymerization: Not likely to occur

Toxicological Information

Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Effects: Mechanical irritation to eyes, skin, and lungs. Inhalation may cause coughing, sneezing, or shortness of breath.
Chronic Effects: Overexposure may cause siderosis (benign pneumoconiosis) with repeated inhalation of dust.
Toxicity Data: LD50 (oral, rat): Not considered acutely toxic; very high doses may affect the gastrointestinal tract.
Carcinogenicity/Mutagenicity: Not listed as a carcinogen by IARC, NTP, or OSHA. No evidence of mutagenic effects.

Ecological Information

Aquatic Toxicity: Insoluble in water; not expected to pose significant risk in small quantities. Large releases may affect aquatic organisms by physically clouding water.
Persistence and Degradability: Iron is naturally occurring and cycles in the environment.
Bioaccumulation Potential: Not considered bioaccumulative.
Mobility: Settles in water due to density; low environmental mobility for particulate form.

Disposal Considerations

Waste Disposal: Collect and place waste material in sealed containers for recycling or landfill, as allowed by local regulation. Do not dispose of in sewers or waterways.
Contaminated Packaging: Empty containers can hold product residue; treat as hazardous.
Regulatory Requirements: Follow local, regional, and national regulations for disposal and recycling of metallic iron.

Transport Information

UN Number: Not classified as a hazardous material for transport
Proper Shipping Name: Iron, Metal
Transport Hazard Class: Not regulated under most international or domestic agencies
Packing Group: Not assigned
Environmental Hazards: Not considered a marine pollutant or environmental hazard
Special Transport Precautions: Avoid transporting together with strong oxidizers and acids. Package securely to prevent dust release.

Regulatory Information

Inventory Listings: Listed in TSCA (US), EINECS/ELINCS (EU), DSL (Canada), and other major regulatory lists
OSHA Hazards: Iron Powder can be considered hazardous due to potential for dust generation
Reporting Requirements: Not subject to Section 313 of SARA Title III
