Conclusions:
The distribution of the flake size of HBPA indicates that it will not represent an inhalation hazard.

Description of key information

The flakes of this substance vary from 10 mm3 to 90 mm3 in volume.

Additional information

The size of 100 HBPA flakes was measured with slide callipers (Accuracy ± 0.1%).

The distribution of the flake size of HBPA indicates that it will not represent an inhalation hazard.
