Susceptibility of Material to Burning
Inflammable means the material will burn. Think of inflammation, if you have an inflamed wound it is red and hot to the touch. As recently as about 15 years ago, trucks and containers were marked
inflammable if they contained material that could burn. Material that won't burn is called non-inflammable.
The problem was that many people assumed inflammable meant that a material would not burn - a potentially deadly mistake. Today, the word
flammable has replaced
inflammable almost entirely, but don't be confused if you encounter the older term.
- Material will not burn.
- Material must be pre-heated before ignition can occur.
- Material must be moderately heated or exposed to relatively high ambient temperature before ignition can occur.
- Liquids and solids that can be ignited under almost all ambient temperature conditions.
- Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air and that will burn readily.
