Product Name/Synonyms: L-Lysine monohydrochloride or Lysine Hydrochloride or 2,6-Diaminohexanoic acid monohydrochloride or 2,6-Diaminohexanoic Acid Hydrochloride.
CAS#: 657-27-2
EINECS EC Number: 211-519-9Section 4: First Aid Measures
Always get medical attention after the first aid is over.
Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention if irritation occurs.
Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion: Do Not induce vomiting unless directed to do so by medical personnel. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing.
Notes to Physician: Provide general supportive measures and treat symptomatically.Section 5: Fire and Explosion Data
Flammability of the Product: Not classed as fire hazard but it may be combustible at high temperature.
Auto-Ignition Temperature: Not available.
Products of Combustion: Oxides of carbon, hydrogen chloride, nitrogen and ammonia along with fumes .
Fire Fighting Media and Instructions: Use DRY chemical powder, water spray, carbon dioxide, fog or foam. Do not use water jet. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used.Section 6: Accidental Release Measures
Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Ensure adequate ventilation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind.
Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to drain or as required by law. Use personal protective equipment. Keep people away from and upwind of spill/leak. Entry to non-involved personnel should be controlled around the leakage area by roping off, etc.Section 7: Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Conditions for safe storage, including any incompatibilities: Store in cool, dry and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like oxidizing agents. Empty containers pose a fire risk, evaporate the residue under a fume hood. Ground all equipment containing material.Section 8: Exposure Controls/Personal Protection
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.
Exposure Limits: Not established by any agency.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice.Section 9: Physical and Chemical Properties
