Product Identifier Product Form: Mixture Product Name: : Neodymium Iron Boron (NdFeB) Magnet, AKA: Rare Earth Magnet 1.2. Intended Use of Product: Permanent magnet for various uses. 1.3. Name, Address, and Telephone of the Responsible Party: Allstar Magnetics 15100 NE 65th Street, Suite 170 Vancouver, WA 98682 1-800-949-8950 https://allstarmagnetics.com 1.4 Emergency Telephone Number: Within USA and Canada 1-800-424-9300 or +1 703-527-3887 (collect calls accepted) Section 2: Hazard(s) Identification 2.1. Classification of the Substance or Mixture Classification (GHS-US) Not classified 2.2. Label Elements GHS-US Labeling No labeling applicable 2.3. Other Hazards Under normal conditions of use and handling in the solid form, harmful substances cannot be released, nor is the solid metal piece considered flammable. Much of the information provided in this SDS is for situations of use in which hazardous exposures may occur, such as in welding applications or for metals in powder form. Magnets have very strong magnetic forces which make them attract to other magnets and other ferromagnetic materials such as iron or steel. This may result in injury during handling of magnets. Strong magnets may affect the operation of pacemakers or other implanted medical devices. 2.4. Unknown Acute Toxicity (GHS-US) No data available Section 3: Composition/ Information on Ingredients 3.1. Substance Neodymium iron boron 3.2. Chemical Formula: Nd2Fe14B Section 4: First-Aid Measures 4.1. Description of First Aid Measures First-aid Measures General: If medical advice is needed, have product SDS at hand. First-aid Measures After Inhalation: If inhaled, move to fresh air and keep at rest in a position comfortable for breathing. Obtain medical attention if breathing difficulty persists. First-aid Measures After Skin Contact: Wash immediately with plenty of soap and water. Rinse with plenty of water. Remove contaminated clothing. Wash contaminated clothing before reuse. Obtain medical attention if irritation develops or persists. First-aid Measures After Eye Contact: Immediately rinse with water for a prolonged period (at least 15 minutes) while holding the eyelids wide open. Remove contact lenses, if present and easy to do. Continue rinsing. Obtain medical attention if irritation develops or persists. First-aid Measures After Ingestion: If swallowed, do not induce vomiting: seek medical advice immediately and show this SDS. 4.2. Most important symptoms and effects, both acute and delayed Symptoms/Injuries: The primary acute health hazard associated with this product would be the potential for exposure to fumes during metal processing operations. Under normal conditions of use not expected to present a significant hazard. During processing or physical alteration, flakes or powder cause irritation of the respiratory tract, eyes, skin, and are harmful. Molten SDS NEO, Rev 1.0, 08Feb2024 Page 1 of 6 PAGE 2 material may release toxic, and irritating fumes. Symptoms/Injuries After Inhalation: During processing, inhalation of fumes may cause lung inflammation and injury with symptoms of chest pains, chills, cough, headache, and diarrhea. Inhalation of dusts and fumes can cause metal fume fever. Symptoms can include a metallic or sweet taste in the mouth, sweating, shivering, headache, throat irritation, fever, chills, thirstiness, muscle aches, nausea, vomiting, weakness, fatigue, and shortness of breath. Symptoms/Injuries After Skin Contact: During metal processing, . Dust may cause irritation in skin folds or by contact in combination with tight clothing. Symptoms/Injuries After Eye Contact: Dust generated from material cutting may cause a slight irritation. Slivers may be generated, which could cause mechanical irritation or injure the eye. Symptoms/Injuries After Ingestion: If a large quantity has been ingested: Gastrointestinal irritation. Indication of Any Immediate Medical Attention and Special Treatment Needed If medical advice is needed, have product SDS at hand. Information for Doctors: Ingestion of multiple magnets can pose a serious risk. Consider consulting the algorithm presented in, "Management of Ingested Magnets in Children," (Hussain et al., 2012). Strong magnetic fields found near neodymium magnets can interfere with the operation of implanted medical devices such as pacemakers and ICDs. Section 5: Fire-Fighting Measures 5.1. Extinguishing Media Suitable Extinguishing Media: Earth, sand, Class D dry powder extinguishing agent, without oxygen compounds. Unsuitable Extinguishing Media: Do not use Halon agents or water. 5.2. Special Hazards Arising From the Substance or Mixture Fire Hazard: Dry powders or neodymium magnets will oxidize, smolder, and burn rapidly in the presences of air or oxygen. Maintain powders in water slurry or in inert atmospheres of nitrogen or argon to prevent spontaneous combustion. Magnets may spark on impact. Handle carefully in explosive atmospheres. Explosion Hazard: Product itself is not explosive but if dust is generated, dust clouds suspended in air can be explosive. Reactivity: Hazardous reactions will not occur under normal conditions. 5.3. Advice for Firefighters Firefighting Instructions: Do not breathe fumes from fires or vapors from decomposition. Keep upwind. Protection During Firefighting: Firefighters must use full-face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes to protect against potential hazardous combustion and decomposition products. Section 6: Accidental Release Measures 6.1. Personal Precautions, Protective Equipment and Emergency Procedures 6.1.1. For Non-emergency Personnel Protective Equipment: Wear eye protection. Emergency Procedures: Avoid creating or spreading dust. Eliminate ignition sources. 6.1.2. For Emergency Responders Protective Equipment: Safety glasses. Emergency Procedures: Ventilate area. Eliminate ignition sources. Evacuate unnecessary personnel. 6.2. Environmental Precautions Contain any spills with dikes or absorbents to prevent migration and entry into sewers or streams. 6.3. Methods and Material for Containment and Cleaning Up For Containment: Contain and collect as any solid. Methods for Cleaning Up: Avoid generation of dust during clean-up of spills. Take up mechanically (sweeping, shoveling) and collect in suitable container for disposal. Vacuum must be fitted with HEPA filter to prevent release of particulates during clean- up. Use only non-sparking tools. Use explosion-proof equipment. 6.4. Reference to Other Sections See heading 8, Exposure Controls and Personal Protection. Section 7: Handling and Storage 7.1. Precautions for Safe Handling Large magnets can attract to one another. Strong attractive forces can cause injury. Impacts of magnets can eject chips or bits of magnet material at speed - eye protection should be used. Strong magnetic fields may affect the operation of implanted medical devices such as pacemakers and ICDs. SDS NEO, Rev 1.0, 08Feb2024 Page 2 of 6 PAGE 3 Additional Hazards When Processed: Do not handle until all safety precautions have been read and understood. Fine dust dispersed in air may ignite. Dust deposits should not be allowed to accumulate on surfaces, as these may form an explosive mixture if they are released into the atmosphere in sufficient concentration. Precautions for Safe Handling: Do not breathe dust. Do not get in eyes, on skin, or on clothing. Avoid creating or spreading dust. Always wash hands after handling the product. Do not eat, drink or smoke when using this product. Ensure there is adequate ventilation. Wear recommended personal protective equipment. Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Always wash your hands immediately after handling this product, and once again before leaving the workplace.
