Storage of flammable materials
A- Flammable solutions
Small amounts of flammable solutions are stored in bottles with PTFE (Polytertrafluoroethylene) caps. Its larger amounts are kept in metal cylinders (such as gas cylinders) where a special needle is connected to its outlet valve and the air inside the cylinder is replaced with an inert gas (argon or nitrogen) using a completely dry syringe.
B. Flammable solids
Flammable solids are stored in special boxes filled with inert gas. These boxes are extremely expensive, so some of these materials are sold as solutions, and others are stored in containers containing mineral oil (such as paraffin, etc.) or light hydrocarbon solvents. Weakly flammable solids, such as lithium aluminum hydride or sodium hydride, can be stored in normal air for short periods of time, but for long-term storage, they must be stored in containers filled with an inert gas (argon or nitrogen). .
Some flammable materials are:
1- Fine particles of metals including magnesium, calcium, zirconium, uranium
2- Alkaline metals
3- Metal or non-metal hydrides such as sodium hydride, lithium aluminum hydride
4- Organometallic compounds
5- Alkylated derivatives of metal and non-metal hydrides such as diethylaluminum hydride, butyllithium and trimethylaluminum
6- Metal carbonyls
7- Hydrogenation catalysts such as Nickel Raney
8- White or yellow phosphorus
9- Plutonium
10- tellurol methane
11- Arsin
12- Di Buran
13- Phosphine
14- Ceylon
15- Hydrazine
