The most favorable composition for an explosive can be easily calculated
from the oxygen values of its components. Commercial explosives
must have an oxygen balance close to zero in order to
minimize the amount of toxic gases, particularly carbon monoxide, and
nitrous gases, which are evolved in the fumes.
Further data are found under the respective compounds described in
this book; also, W Thermodynamic Calculation of Decomposition Reactions.
Paraffin
CH3-(CH2)x-CH3
Paraffin serves to impregnate explosive cartridges against moisture.
The technical product may contain ceresin, wax, or fat.

Parallel Connection
Parallelschaltung; branchement en parallèle
In multiple blastings with electric priming, W Bridgewire Detonators are
usually connected in series to the priming line. If the boreholes are
very wet, and there is a real danger of voltage loss, the charges are
