2,5-Dichlorophenol Names ... 2,5-Dichlorophenol (2,5-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH.
The development of NFPA 704 is credited to the Charlotte Fire Department after a fire at the Charlotte Chemical Company in 1959 led to severe injuries to many of the firefighters. [4] [5] Upon arrival, the fire crew found a fire burning inside a vat that firefighters assumed to be burning kerosene. The crew tried to suppress the fire, which ...
Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen. Mixtures of the three gasses are usually depicted in a triangular diagram, known as a ternary plot. Such diagrams are available in the speciality literature.
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
A fire test can be conducted to determine the degree of flammability. Test standards used to make this determination but are not limited to the following: Underwriters Laboratories UL 94 Flammability Testing; International Electrotechnical Commission IEC 60707, 60695-11-10 and 60695-11-20; International Organization for Standardization ISO 9772 ...

For a gas that is a mixture of two or more pure gases (air or natural gas, for example), the gas composition must be known before compressibility can be calculated. Alternatively, the compressibility factor for specific gases can be read from generalized compressibility charts [ 1 ] that plot Z {\displaystyle Z} as a function of pressure at ...
A fire class is a system of categorizing fire with regard to the type of material and fuel for combustion.Class letters are often assigned to the different types of fire, [1] but these differ between territories; there are separate standards for the United States (NFPA 10 Chapter 5.2.1-5.2.5), Europe (DIN EN2 Classification of fires (European Standard) ISO3941 Classification of fires ...
