Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Halotron I. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Halotron I is a fire extinguishing agent based on the raw material HCFC-123 (93%) mixed with tetrafluoromethane and argon as propellants.
Infobox references. Bromochlorofluoromethane or fluorochlorobromomethane, is a chemical compound and trihalomethane derivative with the chemical formula C H Br Cl F. As one of the simplest possible stable chiral compounds, it is useful for fundamental research into this area of chemistry. [1] However, its relative instability to hydrolysis, [2 ...
Infobox references. Bromotrifluoromethane, commonly referred to by the code numbers Halon 1301, R13B1, Halon 13B1 or BTM, is an organic halide with the chemical formula C Br F 3. It is used for gaseous fire suppression as a far less toxic alternative to bromochloromethane. [3]
Bromochloromethane or methylene bromochloride and Halon 1011 is a mixed halomethane.It is a heavy low-viscosity liquid with refractive index 1.4808.. Halon 1011 was invented for use in fire extinguishers in Germany during the mid-1940s, in an attempt to create a less toxic, more effective alternative to carbon tetrachloride.
ISO 3864-4:2011 Part 4: Colorimetric and photometric properties of safety sign materials [4] Part 1 explains how to layout the components of safety signage, dictate the color scheme and sizing information. Part 2 covers the same concepts as part one, but specifically for labels applied on machinery, vehicles and consumer goods.

ISO 7010 is an International Organization for Standardization technical standard for graphical hazard symbols on hazard and safety signs, including those indicating emergency exits. It uses colours and principles set out in ISO 3864 for these symbols, and is intended to provide "safety information that relies as little as possible on the use of ...
