First Aid Measures
【Ingestion】If swallowed, induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. In all cases, get medical attention.
【Inhalation】Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
【Skin】Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid sping material on unaffected skin.
【Eyes】Immediately flush with running water for at least 20 minutes.
Handling and Storage
【Storage】Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Protect from light. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Hazards Identification
【Ingestion】See inhalation.
【Inhalation】TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Effects of contact or inhalation may be delayed.
【Skin】Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
【Eyes】See Inhalation.
【Hazards】Contact with metals may evolve flammable hydrogen gas.
【EC Risk Phrase】22 36/38
【UN (DOT)】2585
Exposure Controls/Personal Protection
【Personal Protection】ear protective gloves and clean body-covering clothing. Use chemical safety ggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
【Respirators】For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
【Poison Class】4
Fire Fighting Measures
【Fire Fighting】Use extinguish using agent most appropriate for surrounding fire. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
【Fire Potential】Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Accidental Release Measures
【Small spills/leaks】ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability and Reactivity
【Incompatibilities】Strong mineral acids.
【Stability】Stable under ordinary conditions of use and storage.
【Decomposition】Fumes of sulfur oxides, phenol, and salicylic acid may occur when heated to decomposition.
【Combustion Products】Fire may produce irritating, corrosive and/or toxic gases.
