Three newly approved sampling and analytical methods (9106, 9109, 9111) for the determination of
methamphetamines on surfaces have been posted on the
NIOSH Manual of Analytical Methods. According to NIOSH, law enforcement officers can employ these methods to detect the presence of surface methamphetamine contamination in suspected clandestine meth lab sites and may also be used to assess whether such areas are safe for human reoccupation.
