Notes: 1. FL: Flammable liquid - the liquid that can sustain the fire after the fire source is removed, the flash point of which does not exceed 61 oC (in a closed cup) or 66 oC (in an open cup). 2. FG: Flammable gas - the gas that can create a flammable and explosive mixture with air at a temperature not exceeding 55 oC. 3. ES - Explosive substance - the substance that can explode or cause an explosion without oxygen. 4. SCL: Spontaneously combustible liquid - the liquid that can combust itself while the fire source is removed, the flash point of which is above 61 oC (in a closed cup) or 66 oC (in an open cup). 5. FS - Flammable substance - the substance that can sustain the fire after the fire source is removed. | ||||||
