HEALTH & SAFETY:
There are no special hazards associated with the storage or handling of this product other than through misuse or mis-application.

INSTALLATION / FIRE:
Once installed, the material poses no abnormal health risks other than through misuse or in the case of fire where at sources in excess of 250 dg.c rapid decomposition occurs developing dense poisonous fumes which can cause a serious health hazard. The gases liberated affect the respiratory system and can cause asphyxiation.

The hazards are as follows:

1) At 300 dg c dense smoke and polymeric isocyanates are liberated.
2) At 800 dg c the smoke decomposes splitting off into hydrogen
cyanide and carbon monoxide as well as other nitrogen compounds.
3) At 1000 dg c substantial amounts of these toxic gases are given off.
