Test for Toxic Agent Vapors Above Suspected Surfaces.
The test for toxic agent vapors can be performed using one of two
different methods. The preferred method is to expose the sampler
underneath an empty box or can, which has been placed open-end down
over the suspected contaminated area. The second method is to place
an activated sampler directly over the suspected area.
When no can or box is available, the normal sampler procedure is used
with one exception-you lay the sampler with the instruction side up on
top of the suspected area.
