Question/Answer

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.

If the ghostwipe expiration date has past but the wipes are still moist, can they safely used?

There are no safety issues to be concerned with the expiration date being past. However, from a regulatory point of view, if anyone were to use the data they would be able to challenge its validity based on that expiration date. There are no studies guaranteeing the stability of the product past the listed expiration date.
