An industrial hygiene professional, Mr. Cheng, at Edwards Air Force base in California informed us that when conducting air monitoring studies around rocket-engine test sites, he observed a high occurrence of NDMA in the air during the transport and transfer of UDMH fuels. This observation is supported by the summary of the industrial hygiene special study: "Evaluation of potential exposures, conducted at the hydrazine blending facility at the Rocky Mountain arsenal in Commerce City, Colorado." In that study, air samples for UDMH and hydrazine were below levels of analytical sensitivity, yet air samples for NDMA were above the regulatory limit. Two studies were obtained from the U.S. Air Force that reported results from industrial hygiene surveys of Titan II rockets for hydrazine, UDMH, and NDMA; and they demonstrated that measurable levels of NDMA were widespread. Fine and Rounbehler (1981) reported NDMA formation in the rocket-fuel industry. Given the above mentioned reports on the presence of NDMA at other rocket-testing sites, we believe there was a potential for exposure to NDMA at Rocketdyne during the transfer of rocket fuel propellants and testing of rockets.
NDMA is considered a probable carcinogen. It is classified as a probable carcinogen by the U.S. EPA. It is classified as a substance reasonably anticipated to be carcinogenic by the NTP. It is classified as a probable carcinogen by IARC (Group 2A) on the basis of sufficient evidence in animals.
