I am always wondering about that ... It says alumina which is afaik a precursor to aluminum. Doesn't make it safe but not automatically hazardous. I am a chemistry noob so take this with a grain of salt. Speaking of salt: NaCl is table salt, Na or Cl will kill you. Tricky! Does anybody want to shed some light if this is something to consider regarding alumina?
