Abstract： The explosion risk assessment was carried out for a waste toner cartridge treatment system. The explosion parameters of ink powder were determined. The release source and ignition source of the system were evaluated. The classification of explosion area was divided and the explosion protection methods were given out according to the assessment venting．The results showed that controlling the concentration of ink powder residues was the key of explosion prevention．Venting was a cheap and easy way maintaining protection method．
