  • Ignitability is something flammable. liquids like alcohol, gasoline, and acetone; solids that combust; oxidizers and compressed gases can ignite at relatively low temperatures.
  • Corrosive materials can rust or decompose. Substances like hydrochloric acid and sulfuric acid can eat through containers.
  • Reactivity is something explosive. Substances that are unstable, and can change violently without detonating; mixtures that can explode when mixed with water; toxic gases released when mixed with water.
  • Toxicity is something poisonous. These substances pose long term human and environmental health effects if they get into the ground water.
