| Reactivity Alerts | Known Catalytic Activity |
| Reactivity Profile | LITHIUM HYDROXIDE, SOLUTION neutralizes acids exothermically to form salts plus water. Reacts with certain metals (such as aluminum and zinc) to form oxides or hydroxides of the metal and generate gaseous hydrogen. May initiate polymerization reactions in polymerizable organic compounds, especially epoxides. May generate flammable and/or toxic gases with ammonium salts, nitrides, halogenated organics, various metals, peroxides, and hydroperoxides. May serve as a catalyst. Reacts when heated above about 84 °C with aqueous solutions of reducing sugars other than sucrose, to evolve toxic levels of carbon monoxide [Bretherick, 5th Ed., 1995]. |
| Chemical Dangers | Decomposes on heating above 924 °C . This produces toxic fumes. The solution in water is a strong base. It reacts violently with acid and is corrosive to aluminium, tin and zinc. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Reacts with strong oxidants. |
| Brandbekämpfung | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:In case of fire in the surroundings, use appropriate extinguishing media. |
| Erste-Hilfe-Maßnahmen | Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention.Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer immediately for medical attention. |
| Freisetungsmaßnahmen | · CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. |
| Erste Hilfe | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:General First Aid: |
| Sichere Lagerung | Separated from food and feedstuffs, strong oxidants and strong acids. Store only in original container. Dry. Well closed. Store in an area without drain or sewer access. |
| Expositionsschutz und Persönliche Schutzausrüstung | · Wear positive pressure self-contained breathing apparatus (SCBA). |
| Freisetung ohne Brand | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: |
| Verschüttetes entsorgen | Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered plastic containers. Carefully collect remainder. Then store and dispose of according to local regulations. |
| Isolation and Evacuation | Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:Immediate precautionary measure |
| Eye Prevention | Wear face shield or eye protection in combination with breathing protection. |
| Inhalation Risk | Evaporation at 20 °C is negligiblea harmful concentration of airborne particles can, however, be reached quickly when dispersed. |
| Skin Prevention | Protective gloves. Protective clothing. |
