The smoke emission in huge quantities is considered one of the main risks for people in case of fire. Smoke, especially if it is dense, stands between the person and the possible escape route from a burning environment. For this reason care should be taken to this phenomenon by people involved in the fire engineering for the fire prevention.

The reference standards are:

IEC 60695-6-1 “Fire hazard testing - Part 6-1: Smoke obscuration - General guidance”

IEC 60695-6-2 “Fire hazard testing - Part 6-2: Smoke obscuration - Summary and relevance of test methods”


The release of smokes from organic materials start well before the material ignition.

Sometimes the smokes emitted in the first phase of the combustion (smouldering) are ignited by sparks or flames nearby.
