BTW, USPS had been using compressed air to clean equipment ~ post offices are incredibly dusty ~ lots of mail moving at near the speed of sound for hours on end, rubbing up against each other, and all that makes lots of dust.

After the anthrax attack they retrofited to use vacuum systems. Most of the aerosolization occurred when anthrax contamination on surfaces was hit with blasts of air at high pressure.

You would not believe......

"After the anthrax attack they retrofited to use vacuum systems. Most of the aerosolization occurred when anthrax contamination on surfaces was hit with blasts of air at high pressure."

There may be some confusion over terms. "Aerosolization" in terms of WMDs is not about just blowing spores with compressed air.

You can blow pure anthrax with compressed air and you'll still be seeing large clumps of spores moving around.

Moreover, the Senate anthrax letters weren't being blown with compressed air when opened, yet their anthrax samples readily aerosolized.
