4.2 Most Important Acute and Delayed Symptoms/Effects
Excerpt from ERG Guide 154 [Substances – Toxic and/or Corrosive (Non-combustible)]: Toxic; inhalation, ingestion or skin contact with this substance may cause severe injury or death. Contact with the molten substance may cause severe burns to the skin and eyes. Avoid any skin contact. The effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. The runoff from firefighting or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
4.3 Indications for Immediate Medical Attention and Special Treatment (if necessary)
No data available.
V. Fire-fighting Measures
5.1 Suitable Extinguishing Media
Excerpt from ERG Guide 154 [Substances – Toxic and/or Corrosive (Non-combustible)]: For small fires: dry chemical, carbon dioxide or water mist. For large fires: dry chemical, carbon dioxide, alcohol-resistant foam or water mist. If there is no danger, move the container away from the fire area. Dike the firefighting water for subsequent treatment; do not discharge it casually. In case of a fire involving tanks or car/trailer loads: fight the fire from the maximum distance or use unmanned hose holders or monitor nozzles. Do not let water enter the container. Cool the container with a large amount of water until the fire is completely extinguished. Evacuate immediately if the safety valve makes a sound or the tank changes color. Always stay away from tanks engulfed in fire. (ERG, 2016)
5.2 Special Hazards Caused by the Chemical
Excerpt from ERG Guide 154 [Substances – Toxic and/or Corrosive (Non-combustible)]: Non-combustible.

Some are oxidizing agents and may ignite combustible materials (such as wood, paper, oil, clothing, etc.). Contact with metals may release flammable hydrogen gas. The container may explode when heated. For electric vehicles or equipment, ERG Guide 147 (lithium-ion batteries) or ERG Guide 138 (sodium batteries) should also be consulted. (ERG, 2016)
5.3 Special Protective Measures for Firefighters
In case of a fire around, use appropriate extinguishing media.

X. Stability and Reactivity
10.1 Reactivity
Decomposes when heated above 924°C, producing toxic fumes. Its aqueous solution is a strong base. Reacts violently with acids and is corrosive to aluminum, tin and zinc, generating flammable/explosive gas (hydrogen – see ICSC 0001). Reacts with strong oxidizing agents.
10.2 Chemical Stability
No data available.
10.3 Possibility of Hazardous Reactions
Lithium hydroxide solution undergoes an exothermic reaction with acids to form salts and water. Reacts with certain metals (such as aluminum and zinc) to form metal oxides or hydroxides and generate gaseous hydrogen. May initiate polymerization reactions in polymerizable organic compounds, especially epoxides. Reactions with ammonium salts, nitrides, halogenated organic compounds, various metals, peroxides and hydroperoxides may produce flammable and/or toxic gases. May act as a catalyst. When heated above approximately 84°C, it reacts with aqueous solutions of reducing sugars other than sucrose to release toxic levels of carbon monoxide [Bretherick, 5th Ed., 1995].
