Dust explosion
Polishing and powder coating booths need explosion venting.
Safety here is encyclopedia, not a workplace assessment. Name the agent: dust, isocyanate, fibre, fume, moisture, fire.
Fire class A1 as metal is reaction language unless an assembly test is cited.
Gefahren
Caustic / acid
The oxide is amphoteric; drain cleaners and strong acids both attack.
Fumes
Welding 5000-series can generate ozone and metal fume; ventilation still applies.
Sharp foil
Industrial foil slitting is a cut hazard.
Hot dross
Remelt furnaces: thermite-like reactions if the charge is wrong.
Brandklasse
Metal
A1 reaction; structural failure by melting/softening.
ACP
PE-cored aluminium composite is a façade fire lesson, not an aluminium lesson.
Powder
Combustible as a dust cloud.
Cans
Thin walls melt; contents dominate the fire load.
Umwelt
Smelter CO₂
Anode carbon + electricity mix set the carbon passport.
Red mud
Bayer residue is an alkaline waste problem still looking for uses.
Recycling
Cans close the loop; mixed shredded auto scrap is messier (iron, coatings).
Hydro clustering
Iceland, Quebec, Norway smelt where rivers are the energy store.
Handhabung
Do not mix steels in remelt
Iron is a poison in many wrought specs.
Store alloys by series
Heat-treatable vs non: mix-ups scrap T6 lots.
Protect from chlorides
Coastal warehouses pit mill-finish sheet.
Lift with clean vacuum or pads
Soft metal bruises.
Codes move. Recheck KS, JIS, EN, NFPA and IBC editions for the job’s jurisdiction.
