Most common is nitrogen.
yes
Flammable liquids should not be used for cleaning purposes near explosives or within an explosives area. It poses a high risk of fire or explosion due to the volatile nature of flammable liquids in the presence of explosives. It is recommended to use non-flammable cleaning alternatives in such sensitive areas.
Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.
Low explosives are materials that deflagrate (burn rapidly) rather than detonate. They are typically less powerful and generate less pressure than high explosives. Two examples of low explosives are black powder and smokeless powder.
Explosives work well.
It doesn't work

Primary high explosives

That is not an accurate statement. Commercial and military explosives are VERY predictable. A good part of my work was PREDICTING what a blast would produce. However, homemade explosives can be VERY dangerous and unpredictable, since they lack any form of quality control in their making.
The three categories of high explosives are primary explosives, secondary explosives, and tertiary explosives. Primary explosives are very sensitive and are used to initiate a detonation. Secondary explosives are more stable and are commonly used in commercial and military applications. Tertiary explosives are less sensitive and are often used as propellants.

The three categories of explosives are: high explosives, including dynamite and TNT, which detonate with a supersonic shockwave; low explosives, such as black powder and gunpowder, which deflagrate with a subsonic burn rate; and secondary explosives, like RDX and PETN, which are more powerful and sensitive than primary explosives like TNT.
all nuclear explosives use some fission. even now.
He worked for the Germans. He developed a process to extract pure nitrogen, which was used to make explosives
