First-aid measures
• Description of first aid measures• After inhalation:If metal vapours or solid dusts have been inhaled:Get the affected person out in the fresh air and call a doctor.• After skin contact:Foreign bodies which have penetrated the skin must be removed and the wound cleaned thoroughly.• After eye contact:Rinse opened eye for several minutes under running water. If symptoms persist, consult a doctor.• After swallowing: Consult a doctor if the symptoms persist.• Information for doctor:• Most important symptoms and effects, both acute and delayed No further relevant information available.• Indication of any immediate medical attention and special treatment neededNo further relevant information available.
Fire-fighting measures
• Extinguishing media• Suitable extinguishing agents:Non-combustible.Extinguishing agents must be adapted to the environment.• Special hazards arising from the substance or mixture No further relevant information available.• Advice for firefighters• Protective equipment: No special measures required.
Accidental release measures
Accidental release of dusts and vapours which are damaging to health can be ruled out.• Personal precautions, protective equipment and emergency procedures No special measures required.• Environmental precautions: No special measures required.• Methods and material for containment and cleaning up: No special measures required.
Handling and storage
• Handling:• Precautions for safe handlingNo protective measures are required in the provided form.Dry mechanical processing of rare earth permanent alloys is only permitted under special safetyprecautions because dusts which are capable of self-heating or pyrophorous dusts with a tendency to explodemay be produced.In the case of wet mechanical processing the watery processing medium reacts with the magnet wear andmay 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 aprotective liquid because drying out sludges are capable of self-heating or may react pyrophorously. In thiscase the stored hydrogen volume burns off with flames.• Information about fire - and explosion protection:No particular measures are required in the provided form.• Conditions for safe storage, including any incompatibilities• Storage:Keep magnetized magnets away from computers, displays and magnetic storage devices. Especially peoplewith heart pacemakers must keep away from magnetic fields.• Requirements to be met by storerooms and receptacles: No special requirements.• Information about storage in one common storage facility: Not required.• Further information about storage conditions: Not applicable• Storage class: Not applicable• Specific end use(s) No further relevant information available.

Exposure controls / personal protection
• Additional information about design of technical facilities:Provide a suitable suction with filter and good ventilation of the working area for all processing steps.Suitable breathing apparatus must be used (see personal safety equipment) for repair and maintenance workon suction systems, especially when changing the filters.• Control parameters• Ingredients with limit values that require monitoring at the workplace:7440-48-4 cobaltDNEL (Inhalation, worker): 40 µg/m³ (REACH-Registration-Dossier)CAS# 7440-42-8 boron: DNEL (Inhalation, worker): 97.95 mg/m³ (REACH-Registration-Dossier)• Additional Occupational Exposure Limit Values for possible hazards during processing:Compliance with the general dust limit value(s) (lung penetrating and/or inhalable fraction) must be ensured.• Additional information: The lists valid during the making were used as basis.• Exposure controls• Personal protective equipment:• General protective and hygienic measures:Keep away from foodstuffs, beverages and feed.Wash hands before breaks and at the end of work.Avoid contact with the eyes and skin.• Respiratory protection:In the case of dust formation (limit value exceeded), breathing apparatus must be worn.Time limits for wearing must be observed.Breathing mask, apparatus with particle filter P2 or P3, for example:- Full face mask (EN 136)- Breathing mask (EN 149) FFP2 or FFP310 times the limit value (FFP2)30 times the limit value (FFP3)Recommendation: P3• Protection of hands:Avoid repeated and prolonged contact with the skin, use protective gloves.Preventive skin protection by use of skin-protecting agents is recommended.• Material of glovesMaterial of gloves: Material of gloves should be impenetrable (e.g. nitrile caoutchouc). Depending on use heat protective gloves are required.• Penetration time of glove material -• Eye protection:Safety goggles / EN 166, with side shields if necessary, must be worn in dusty environments andwhen working with magnetised magnets (> 50 g).• Limitation and supervision of exposure into the environmentThe legal issue values and limitations are to be paid attention!
Stability and reactivity
• Reactivity• Chemical stability• Thermal decomposition / conditions to be avoided: No decomposition if used according to specifications.• Possibility of hazardous reactionsHydrogen is released in contact with acid which can cause explosive gas mixtures.• Conditions to avoid No further relevant information available.• Incompatible materials: No further relevant information available.• Hazardous decomposition products: No dangerous decomposition products known.
Disposal considerations
• Waste treatment methods• Recommendation Observe official regulations.• Uncleaned packaging: Not applicable
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
