Tovex is a 50/50 aqueous solution of ammonium nitrate and methylammonium nitrate (sometimes also called monomethylamine nitrate, or PR-M), sensitized fuels, and other ingredients including sodium nitrate prills, finely divided (paint-grade) aluminum, finely divided coal, proprietary materials to make some grades cap sensitive, and thickening agents to enhance water resistance and to act as ...
Another type of paint marker is the solidified paint pen. This is a type of marker, often contained within a twist tube, that is a cylinder of semi-hardened oil-paint with a pointed tip. As one writes with it, the point wears down and must be advanced to in order to continue writing. The marker leaves a mark similar to that of chalk. It is ...
The bleaches used to remove unwanted fungal stains from wood include two-part peroxide bleach and solutions of sodium hypochlorite. [27] The former is particularly effective at removing the natural colour of wood before it is recoloured with pigmented stains or dyes. [27] Oxalic acid is particularly effective at removing iron stains from wood. [27]
Any fuel-air mixture higher than this would be too concentrated to result in combustion. The values existing between these two limits represent the flammable or explosive range. Within this threshold, give an external ignition source, combustion of the particular fuel would likely happen.
Permanent markers are used for writing on metals, plastics, ceramics, wood, stone, cardboard etc. However, the mark made by them is semi-permanent on some surfaces. Most permanent marker ink can be erased from some plastic surfaces (like polypropylene and teflon) with little rubbing pressure. They can be used on ordinary paper, but the ink ...
Potassium picrate – used in some whistle compositions, safer than gallic acid but still dangerous, with heavy metals (e.g. lead) forms explosive salts; Terephthalic acid – a fuel in some smoke compositions; Hexamine – a low-reactivity, accessory fuel; Anthracene – a fuel in some smoke compositions, produces black smoke
Fuel pumps in Ireland, with green gas oil and red kerosene, and notices that it is an offence to use marked fuels in a motor vehicle. After August 2002, all European Union countries became obliged to add about 6 mg/L (0.034 oz/bbl) of Solvent Yellow 124, a dye with structure similar to Solvent Yellow 56, to heating fuel.
In this case, sodium was able to react with water to release hydrogen gas and large amounts of heat, which has the potential to explode. The Charlotte Fire Department developed training to respond to fires involving hazardous materials, ensured that protective clothing was available to those responding, and expanded the fire prevention ...
