§ 175.630

Special requirements for Di-

vision 6.1 (poisonous) material and 
Division 6.2 (infectious substances) 
materials. 

(a) [Reserved] 
(b) No person may operate an aircraft 

that has been used to transport any 
package required to bear a POISON or 
POISON INHALATION HAZARD label 
unless, upon removal of such package, 
the area in the aircraft in which it was 
carried is visually inspected for evi-
dence of leakage, spillage, or other 
contamination. All contamination dis-
covered must be either isolated or re-
moved from the aircraft. 

(c) When unloaded from the aircraft, 

each package, overpack, pallet, or unit 
load device containing a Division 6.2 
material must be inspected for signs of 
leakage. If evidence of leakage is 
found, the cargo compartment in which 
the package, overpack, or unit load de-
vice was transported must be dis-
infected. Disinfection may be by any 
means that will make the material re-
leased ineffective at transmitting dis-
ease.
