About

• Oxidizing materials contain “excess” oxygen which is released when the temperature is elevated, when it is exposed to air or when combined with other chemicals. This oxygen release makes oxidizing chemicals extremely flammable and combustible. Most oxidizing chemicals are labeled with information about the chemical, safety precautions and, in some cases, the diamond-shaped warning label issued by the National Fire Protection Association (NFPA). The NFPA system classifies the fire and corrosive danger of chemicals on a scale of zero (no hazard) to four (extremely hazardous). Oxidizing agents are usually labeled between one and four.
  
  

Household Oxidizers

• One of the most common household oxidizing reactions includes corrosion, when metals react with air and moisture to produce oxides, or rust. First aid and cleaning agents also often contain oxidizing agents, such as hydrogen peroxide, nitric acids, bromates and chlorates. Compounds containing nitrates, persulfates, peroxides, and perborates have strong oxidizing potential.
  
  

Ammonium Perchlorate

• One of the most dangerous oxidants that may be found in a household is ammonium perchlorate. It is odorless and colorless – and extremely combustible – and is often found in fireworks. It decomposes at high temperatures, releasing toxic levels of chlorine, hydrogen chloride and nitrogen oxide which can not only ignite, but is dangerous if inhaled.
  
  

Safety

• Never store oxidizing agents near organic or flammable materials, and keep the chemicals in temperature-controlled environments. Always handle oxidants with extreme caution and wear protective gloves and eye wear, as many are also corrosive. Keep chemicals away from children and pets. If you are unsure about a chemical, or have any questions or doubts about whether a substance contains oxidizing agents, do not dispose of it in household garbage. Isolate the chemical and call your local fire department or hazardous materials teams.
