See heading 13 for Disposal Information Section 7: Handling and Storage 7.1. Precautions for Safe Handling: No protective measures are required in the provided form. Additional Hazards When Processed: 7.1.1. Dry Mechanical Processing: This processing of rare earth permanent magnet alloys is permitted only under special safety precautions because dusts which are capable of self-heating or pyrophoric dusts with a tendency to explode may be produced. 7.1.2. Wet Mechanical Processing: Watery processing medium can react with the magnet grinding and may form hydrogen already at room temperature. Attention – Formation of ex-atmospheres possible! Part of the resulting hydrogen is stored in the material. The resulting processing sludges must be kept under a protective liquid because dried out sludge are capable of self-heating or may react. In this case, stored hydrogen volume burns off with flames. Also, see Section 8. Conditions for Safe Storage, Including Any Incompatibilities: Please keep magnetized magnets away from computers, displays and magnetic storage devices, like floppy discs, magnetic tapes or credit cards as it can destroy or alter the magnetic data. People with heart pacemakers must keep away from magnetic fields. Storeroom and Receptacle Requirements: Store in dry location free of corrosive atmosphere. Keep away from magnetic objects such as iron, cobalt or nickel and high energy magnetic fields. Section 8: Exposure Controls/Personal Protection Additional Information about Design of Technical Systems: Provide filtered ventilation of working area for all processing steps. Suitable breathing apparatus must be used (see personal safety equipment) for repair and maintenance work on air handling systems, especially during filter changes. 8.1.
