BC dry chemical agents are incompatible with strong acids, lithium metal and sodium potassium alloy Na. K, and monoammonium dihydrogen phosphate also called ammonium phosphate, NH4. H2. PO4. Mixing of fire fighting agents with incompatible materials can release toxic byproducts or pose other dangers. Alternative extinguishing agents should be used in areas where incompatible materials are likely to be used or encountered. For example, pool chemicals should be stored separate from other hazards and water extinguishers see above or carbon dioxide units should be provided.
