HEALTH/ENVIRONMENTAL HAZARD
Fitter canisters use ASC Whetlerite Carbon which contains Chromium VI. Chromium VI is a known carcinogen if
inhaled or swallowed. Damaged or unusable canisters are classified as hazardous waste:
DO NOT throw away damaged or unusable canisters as ordinary trash.
DO turn in damaged or unusuable canisters to your hazardous waste management office or Defense
Reutilization and Marketing Office (DRMO).
Canisters are completely safe to handle and use if they are not damaged in such away that carbon leaks from
them. In unlikely event that carbon should leak, use protection such as a dust respirator to cover nose and
mouth and put carbon in container such as self-sealing plastic bag; turn into hazardous waste management
office or DRMO.
Disposal of hazardous waste is restricted by the Resource Conservation and Recovery Act as amended
(42 U.S.C.A. sec 6901 et seq). Violation of these laws is subject to severe criminal penalties.
