Question/Answer

Can you use expired GhostWipes for sampling?

We do not recommend that any expired product be used in a testing procedure for reportable data. Use of an expired product could potentially invalidate the data generated.

What Niosh method would a lab use to analyse the sample of lead of a ghost wipe?

Always consult the appropriate regulating agency for approved analytical methods. Currently, Housing and Urban Development has approved test methods listed in appendix 14.1 which can be found here http://www.hud.gov/offices/lead/lbp/hudguidelines/Appendix.pdf The HotBlock manual has an adaptation of NIOSH 7082 for use in digesting GhostWipes.
