Flash point is the lowest temperature at which a chemical can vaporize to form an ignitable mixture in air. A lower flash point indicates higher flammability.13 ene 2016
What makes a substance flammable?
Flammable substances are those gases, liquids and solids that will ignite and continue to burn in air if exposed to a source of ignition. ... It is their vapours combined with air, not the liquid or solids themselves, that ignite and burn.
What is classed as flammable?
A material is considered flammable if it has a flash point of any temperature below 37.8 ºC. A material is considered combustible if it has a flash point higher than 37.8 ºC and below 93.3 ºC. ... Therefore, the lower the flash point of a material, the higher the risk is.28 ene 2019
What are considered flammable materials?
- Examples: gasoline, acetone, toluene, diethyl ether, alcohols.
- Hazard: May produce ignitable vapors at normal ambient temperatures.
How do you handle flammable liquids?
Eliminate ignition sources (sparks, smoking, flames, hot surfaces) when working with flammable and combustible liquids. Use the smallest amount of flammable liquid necessary in the work area. Keep storage areas cool and dry. Store flammable and combustible liquids away from incompatible materials (e.g., oxidizers).
What causes a material to be flammable?
A material's ability to ignite is dictated by the strength of bonds between molecules within the substance and the ease of oxidation. Though there are others, the most common definition for flammability is, “burns in the presence of a spark at under 199.4 degrees Fahrenheit”, as defined by OSHA 29 CFR 1910.106.
