such as dynamite, nitroglycerine, lead azide, TNT, Composition B,

blasting must be prevented (W Permitted Explosives).
Column Charge
Gestreckte Ladung; file de cartouches
A charge of explosives in a blast hole in the form of a long continuous

Combustibility
Feuergefährlichkeit; danger d’inflammation
Capability of burning. Flammable. The relative combustibility of materials
in storage is defined as: hazardous – materials that by themselves
or in combination with their packaging, are easily ignited and will
contribute to the intensity and rapid spread of a fire; moderate –
materials and their packaging both of which will contribute fuel to a
fire; noncombustible – materials and their packaging that will neither
ignite nor support combustion.
