Household Chemical Incompatibilities Chart
Read labels carefully to identify specific chemical compounds and chemical family before using this chart. Certain household chemicals can be dangerous if stored next to incompatible chemicals. Be aware that certain chemical reactions can actually start a fire when adjacent to combustible materials. Other chemical reactions may produce poisonous gases.
