4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Releases oxygen at high temperatures. Incompatible with mixtures containing heavy metal salts, combustible organic matter or moisture. Decomposition can occur gradually, releasing controlled amounts of oxygen. Hazardous polymerisation will not occur. Avoid contact with heat and humidity sources. Avoid flammable compounds, very reactive organic compounds, heavy metals salts, reducing compounds, acids and alkalis.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. In case of fire use water to extinguish. Use equipment/ media appropriate to surrounding fire conditions. 5 OTHER INFORMATION
Other Information
When it is used, or in waste water, tetrahydrate sodium perborate rapidly degrades and develops sodium borate and hydrogen peroxide. The latter further breaks down into water and oxygen.
