Pokraskin Carbon blacks will burn slowly (smoulder) and sustain combustion that may not be visible in the powder or pellet form (no visible flames or smoke). A direct water spray or stream may spread the fire due to the burning carbon black powder floating on the water. A fog spray is recommended when water is used as an extinguishing agent. Foam is also an acceptable extinguishing agent. Carbon black that has been on fire (or suspected of being on fire) should be observed for at least 48 h to ensure that smouldering material is not present. Combustion gases include carbon monoxide, carbon dioxide, sulfur dioxide, and organic products of decomposition.
