Open the CIPO recordAbstract From the Canadian patent
The present invention describes a new fire-extinguishing and fire-prevention process in which calcium precipitates and/or specially activated calcium carbonate, i.e. specially finely ground or finely divided calcium carbonate that is environmentally friendly and not injurious to health is used. This seals the burning surface immediately and breaks the reaction chain. The toxic gases and injurious substances that are released by the thermal decomposition of plastics react with the calcium carbonate and are bound so that no dioxins including, toxic chlorinated and/or fluorinated hydrocarbons are formed.

Why it's free to use
- Filed April 18, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 18, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 18, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
