Guidance on Safe Use
Administrative data
First-aid measures
First-aid measures general : If you feel unwell, seek medical advice.First-aid measures after inhalation : Remove the victim into fresh air. Respiratory problems: consult a doctor/medical service.First-aid measures after skin contact : Wash immediately with lots of water. Soap may be used. Take victim to a doctor if irritationpersists.First-aid measures after eye contact : Rinse immediately with plenty of water. Take victim to an ophthalmologist if irritation persists.First-aid measures after ingestion : Rinse mouth with water. Call Poison Information Centre(www.who.int/ipcs/poisons/centre/directory/en). Consult a doctor/medical service if you feelunwell.
Fire-fighting measures
Suitable extinguishing media : AFFF foam. BC powder. Carbon dioxide. Dry sand. Dry chemical powder. Adapt extinguishingmedia to the environment.Unsuitable extinguishing media : Solid water jet ineffective as extinguishing medium.Fire hazard : DIRECT FIRE HAZARD. Combustible. In finely divided state: increased fire hazard. INDIRECTFIRE HAZARD. Temperature above flashpoint: higher fire/explosion hazard.Explosion hazard : DIRECT EXPLOSION HAZARD. Its dust is explosive with air. INDIRECT EXPLOSIONHAZARD. Dust cloud can be ignited by a spark.Reactivity : On burning: release of (carbon monoxide - carbon dioxide).
Accidental release measures
Personal precautions, protective equipment and emergency proceduresGeneral measures : Mark the danger area. Prevent dust cloud formation, e.g. by wetting. Dust production: haveneighbourhood close doors and windows. Exposure to heat: have neighbourhood close doorsand windows. In case of dust production: no naked flames or sparks. Dust: spark-/explosionproof appliances/lighting equipment. For non-emergency personnelProtective equipment : See "Material-Handling" to select protective clothing. For emergency respondersProtective equipment : Use protective measures listed in Section 8. Environmental precautionsPrevent soil and water pollution. Methods and material for containment and cleaning upFor containment : Knock down/dilute dust cloud with water spray.Methods for cleaning up : Carefully collect the spill/leftovers. If melted: allow liquid to solidify before taking it up. Scoopsolid spill into closing containers or into synthetic bags. Clean contaminated surfaces with anexcess of water and soap solution.
Handling and storage
Precautions for safe handlingHandling temperature : ≥ 10 °C above melting point Conditions for safe storage, including any incompatibilitiesProhibitions on mixed storage : KEEP SUBSTANCE AWAY FROM: ignition sources. (strong) acids. (strong) bases.Storage area : Keep container in a well-ventilated place. Store at ambient temperature. Keep out of directsunlight. Meet the legal requirements.Special rules on packaging : SPECIAL REQUIREMENTS: closing. correctly labelled. meet the legal requirements.

ReactivityOn burning: release of (carbon monoxide - carbon dioxide). Chemical stabilityStable under normal conditions.
Disposal considerations
Waste treatment methodsDisposal : Scoop solid spill into closing containers,Powdered: do not use compressed air for pumping overspills,Clean contaminated surfaces with a soap solutionRegional legislation (waste) : No supplementary information available.Ecology - waste materials : Do not discharge into drains or the environment. Remove to an authorized waste treatmentplant.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
