General Safety Advice Please!

[Screwdriver]

Ok so a few months ago I got my first TiG and accidentally discovered they can create phosgene gas if you hit any (old style) brake cleaner. Same thread went on to give warnings about galvanised steel too.

Are there any similar tips for plasma cutting? I've heard the one about aluminium forming a dust which you shouldn't breathe and having just tested my new toy, discover it really makes the workshop stink of ozone! It's quite a nice stink mind.

Anyhow, any safety tips gratefully received, ideally before I do myself a mischief.

Phosgene is a possible byproduct of heating ANY chlorinated solvent. Brake cleaner in the UK is the non-chlorinated flavour but given the fire risks with heating/welding around solvents it's a good idea to be sure that it's all cleaned up and/or had time to evaporate...

No fume is healthy, TIG generally one of the cleanest as no filler is transfered across the arc. TIG and galvanised/zintec = trashed tungsten although zintec can be brazed with TIG without wrecking the coating and/or tungsten.
Ozone is the biggy with TIG, more so at higher amps + reflective materials like aluminium for example. The scratchy throat and tight chest that's sometimes blamed on argon after a long day welding is more likely the result of ozone

Many thanks. Will read and digest later.

Just back in from turning bits of scrap into, um, smaller bits of scrap!
