|NIOSH-developed Full Disclosure® Wipe Sampling Kits provide instant detection of lead on skin and surfaces. Full Disclosure identifies lead contamination at greater than 18 µg using a wipe with colorimetric results. Use Full Disclosure lead wipes for determining the effectiveness of lead removal and spot-checking lead-contaminated surfaces to eliminate lead as a take-home toxic.|
Yellow to Orange = Lead < 18 µg
Pink to Red = Lead > 18 µg
Determine the effectiveness of hand washing to remove lead residues: Individuals exposed to lead in their work or at a shooting range can use Full Disclosure wipes prior to eating, drinking, or smoking, and at the end of the workday to ensure lead has been completely removed from their hands and other body parts during washing. By demonstrating the effectiveness (or lack thereof) of washing for removal of lead residues, individuals are better able to prevent toxic hand-off to other surfaces and individuals.
Educate workers in industries where lead is an occupational hazard: The on-the-spot color change provides immediate feedback to exposed workers on the importance of adequate hand washing. Full Disclosure wipes should be an integral part of safety training for workers in lead industries.
Spot-check lead-contaminated work surfaces: Lead change rooms, for example, may have a prescribed cleaning regimen. Full Disclosure wipes can be used to spot-check lead-contaminated work surfaces to ensure that a prescribed cleaning regimen has resulted in the desired "clean" levels. Similarly, they can be used to check surfaces such as steering wheels, doorknobs, and hand tools touched by lead-contaminated workers.
Note: Full Disclosure is not intended to detect
lead in paint, paint chips, on painted surfaces, or embedded in material
such as plastic and is not suitable for lead chromate.
Evaluate the presence of lead and the effectiveness of its removal: Field evaluations can be performed easily in homes, schools, and other similar environments.
Wipe the test surface, i.e., skin, safety glasses,
tables, workbenches, shoes, etc. with a wipe to collect lead that
may be present.
Spray the mildly acidic aqueous solution onto the wipe to solubilize the lead, then spray the aqueous rhodizonate test reagent onto the wipe.
Read the Results. If solubilized lead is present, a pink to red color bloom will appear immediately. The intensity of the color bloom can indicate the relative amount of lead present. Positive wipes can be sent to a laboratory for quantitative analysis if desired.
Note: Full Disclosure was developed to detect the presence of elemental lead and some lead salts. The extraction solution will not solubilize all lead salts. Full Disclosure is suitable for elemental lead, lead nitrate, lead sulfate, and lead oxide. Full Disclosure will not detect lead chromate or alkyl lead.
