More is known about arsenic- containing compounds in general, but caution must be used in extrapolation. Some evidence suggests that L might be a expected to constitute an airborne hazard unless H is also present at concentrations much higher than permitted. More is known about arsenic- containing compounds in general, but caution must be used in extrapolation. Some evidence suggests that L might be a carcinogen. CDC, in its continuous oversight of demilitarization activity, routinely examines each of the eight chemical storage sites in the United States and a chemical munitions incineration facility that has been in operation in Utah since 1979.
Consideration is given to the population centers in the surrounding communities at depots.
Standard operating procedures for agent handling and worker safety are also observed. This experience indicates that the control limits in Table 1 are attainable. Questions related to the nerve agents have been relatively easy to resolve. The information bases are fairly complete, and there appears to be little risk either of adverse health effects from long-term exposure to low doses or of delayed health effects from acute exposure. This can be accomplished by use of appropriate engineering controls, personal protective equipment, and work practices.
