It follows the Toronto convention on CFC`s, for example R-12,R-22 (refrigerant gasses) and Halon among others. some countries are still allowed to manufacture some of the legacy gasses, but even they have a future no manufacture date. For example The US and Canada are no longer allowed to manufacture R-12 or Halon. Sales are allowed if you can prove that your stock is lagacy and not smuggled. I belive the new fire suppresant is an extremly fine powder under pressure ~ like halon. Once released it must stay in suspension for an minimum predetermined ammount of time( i forget how long) and reach a predetrmind height in the sealed room it is supposed to protect. Re: legacy gasses. Everthing eventually leaks, so eventually that money will have to be spent. -----BEGIN PGP SIGNATURE----- Version: PGP 6.5.2 Comment: Using PGP with Mozilla - http://enigmail.mozdev.org iQA/AwUBPrcqeX9fi/+iwn3tEQJSrwCgj4qjrEMpn6i9S2zHsb+kePYB8PEAoLGh QB5sgKoxmpkoTs/8VmD94Z3r =bA// -----END PGP SIGNATURE----- _________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.netisland.net/mailman/listinfo/plug-announce General Discussion -- http://lists.netisland.net/mailman/listinfo/plug
