Tungsten hexafluoride
Tungsten(VI) fluoride, also known as tungsten hexafluoride, is an inorganic compound with the formula WF6. It is a toxic, corrosive, colorless gas, with a density of about 13 kg/m3 (22 lb/cu yd) (roughly 11 times heavier than air). It is one of the densest known gases under standard conditions. WF6 ls commonly used by the semiconductor industry to form tungsten films, through the process of chemical vapor deposition. Wikipedia

Segregation Chart for Load, Transport, Storage
In this table a statement is contained for each hazard class whether the loading, transport or storage with other hazard classes is allowed, is not permitted or is restricted. The table is based on U.S.-Code 49 CFR §177.848.
Note: In this segregation and separation chart are HazMat of hazard class 2.3 considered depending on their poisonousness by inhalation (Hazard zone B). See special provision 2 and PHMSA Interpretation #09-0252.
