Manufacturer/Supplier: Various global producers and chemical suppliers
Contact Telephone: Emergency phone numbers listed by each country’s poison control center or safety agency
GHS Classification: No classification as hazardous under GHS criteria
Health Hazards: Dust may cause mechanical irritation to eyes, nose, and throat; prolonged inhalation can lead to mild respiratory effects
Environmental Hazards: Not considered hazardous for the environment; poorly soluble in water; persistence in aquatic and soil environments
Label Elements: None required under GHS; no pictogram mandated
Other Hazards: Dust clouds in confined areas can present explosion risk in rare cases
Chemical Name: Iron(III) oxide
CAS No.: 1309-37-1
EC No.: 215-168-2
Pigment Content: Typically 95% or higher by weight
Impurities: Trace minerals (silica, alumina, manganese oxide) possible depending on the manufacturing process
Stabilizing Additives: None typically added
Eye Contact: Flush thoroughly with water for at least 15 minutes; seek medical attention if redness or discomfort persists
Skin Contact: Rinse skin with soap and water; unlikely to cause irritation unless pre-existing dermatitis exists
Inhalation: Move person to fresh air; encourage deep breathing; seek observation if respiratory symptoms linger
Ingestion: Rinse mouth, drink water to dilute; ingestion in small quantities is not expected to cause harm
Most Important Symptoms: Irritation of respiratory tract, sneezing from dust exposure
Suitable Extinguishing Media: Use water spray, foam, dry powder, or carbon dioxide for surrounding fire
Unsuitable Media: None known
Special Hazards: Product itself does not burn; iron oxide dust can promote smoldering of organic materials in fire
Protective Equipment: Full protective equipment and self-contained breathing gear for fire involving chemicals
Other Notes: Prevent run-off from entering watercourses and drains
Personal Precautions: Wear dust mask, goggles, gloves to avoid eye or lung irritation
Environmental Precautions: Prevent discharge into drains, surface or ground waters
Spill Cleanup Methods: Sweep up using methods minimizing dust (damp sweeping, HEPA vacuum), collect in suitable labeled containers for reuse or disposal
Reference to Other Sections: Consult appropriate disposal, personal protection, and handling instructions
Emergency Procedures: Evacuate unprotected personnel, ventilate spill area
Handling: Use local exhaust ventilation or respiratory protection; avoid generating dusty conditions; do not eat, drink, or smoke while handling
Storage Conditions: Store in tightly sealed containers in dry, well-ventilated place
Storage Temperature: Stable under normal room temperatures; avoid excessive humidity
Incompatible Materials: Avoid strong acids or other reactive chemicals; oxidizing agents will not react with iron oxide under normal conditions
Packing Materials: Paper, polyethylene-lined bags, or fiber drums, which prevent ingress of moisture
Occupational Exposure Limits: OSHA PEL (respirable dust): 5 mg/m3; ACGIH TLV (total dust): 10 mg/m3
Engineering Controls: Use process enclosures, local exhaust ventilation to control airborne dust
Respiratory Protection: Appropriate NIOSH-approved particulate respirator for dust if airborne exposure exceeds limits
Eye Protection: Safety goggles or glasses with side shields
Skin Protection: Gloves and coveralls recommended for bulk handling
Hygiene Measures: Wash hands before eating, drinking, or leaving work site; avoid bringing contaminated clothing home
Appearance: Fine red-brown to deep red powder
Odor: Odorless
pH: Not applicable in dry state; slight alkalinity in aqueous suspension
Melting Point: Above 1500 °C
Boiling Point: Not available; material decomposes
Solubility: Insoluble in water, organic solvents
Density: Approximately 5.2 g/cm3
Particle Size: Typically 0.1 – 1 µm (micronized grades)
Vapor Pressure: Negligible
Other Data: Stable under ambient temperature and pressure
Chemical Stability: Chemically stable under normal handling and storage
Reactivity: Inert substance under ordinary conditions; non-flammable, non-combustible
Conditions to Avoid: High humidity, wet storage can promote lumping, slow caking
Incompatible Materials: Strong acids (forming soluble iron salts); reducing agents in high temperature process settings
Hazardous Decomposition Products: No hazardous decomposition when stored or handled properly
Polymerization: Will not occur
Acute Toxicity: Low acute toxicity by oral, dermal, or inhalation routes; LD50 (oral, rat): >5000 mg/kg
Chronic Toxicity: Prolonged dust exposure can trigger pneumoconiosis (siderosis) detectable only radiographically and not associated with physical symptoms or disability
Skin Irritation: Not expected to irritate intact skin
Eye Effects: Mild mechanical irritation from dust without permanent injury
Inhalation: Exposure above permissible limits may cause coughing, respiratory irritation; symptoms usually reversible
Carcinogenicity: Classified as not carcinogenic by IARC, NTP, OSHA
Mutagenicity: No data supporting mutagenic risk
Ecotoxicity: Not expected to have significant effects on aquatic organisms in typical applications
Persistence and Degradability: Stable mineral, practically non-biodegradable
Mobility in Soil: Low mobility; binds strongly to soil particles, unlikely to leach into groundwater
Bioaccumulative Potential: Bioaccumulation considered insignificant for iron(III) oxide
Other Adverse Effects: Can contribute to sediment coloration in local waterways; deposition onto plants and soil generally seen as inert
Waste Treatment Methods: Material may be reused, recycled, or disposed as non-hazardous industrial waste according to local, regional, and national regulations
Container Disposal: Reseal or triple rinse empty containers, then dispose in accordance with statutory requirements
Precautions: Avoid generation of dust during disposal activities; wear protective equipment as for product handling
Environmental Considerations: Prevent bulk discharges into waterways to avoid unnecessary siltation or sedimentation
UN Number: Not regulated for transport under ADR, RID, IMDG, IATA codes
Proper Shipping Name: Iron oxide pigment or related mineral pigment
Hazard Class: Not classified as a dangerous good
Packing Group: None assigned
Transport Labels: Not required
Special Precautions: Protect from moisture; load securely to prevent spills during transfer
Inventory Status: Listed as existing chemical under inventories in the United States (TSCA), EU (REACH), Canada (DSL), Australia (AICS), Japan (ENCS), China (IECSC)
Labeling Requirements: No labeling required per GHS or equivalent national systems for this product; consult regional guidelines
Other Regulation: Manage in compliance with local occupational health and environmental protection laws; consult worker safety regulations for permissible exposure levels
Specific Provisions: Material not subject to specific restrictions on manufacture or use in US, EU, or other countries reviewed
