>How much of what you learn in chemistry (second or tertiary level) is applicable to HE and pyrotechnics?
Safe lab practises is the big one, while making HE you are going to be working with fumes, gases and acids so basic lab safety matters.
>what would you recommend people learn before even considering HE/pyro experiments?
Read the MSDS (material safety data sheet) for everything you are working with, learn about static electricity generation and mitigation as this is still the biggest killer today.
>What kind of HE/pyro compositions should people look at when starting out?
Nitrocellulose is perfect as it's a nitration which is good to know but the product is very safe if made pH neutral. If something goes wrong and your nitration bath gets hot NC is safe to quench in water.
>What should they avoid at all costs?
Organic peroxides especially TATP, people see how easy to make it is and are drawn to it but the reality is nitro compounds are just as easy and much safer.
>How much safety equipment should a pyro use?
Face shield, respirator, gloves and full cotton clothes for the lab, heavy gloves, face shield, tongs and heavy jacket for making detonators.
While working in heavy gloves is a pain in the ass you need to think about whatever you are touching would do at ~6,000 m/s, if you can use tongs to avoid directly touching any HE / HE device.
>what books would you recommend?
The chemistry of powder and explosives is the goto for info on any HE, keep in mind it's very old so before making anything read modern MSDSs and lab practises.
>And is there anything else an aspiring pyro should know?
Static kills, ground everything, wear all cotton, choose the right plastics and never be afraid to douse a reaction if it goes out of range.
