NIOSH 5700 – Product & Materials Guide

Concentration of Formaldehyde in Textile or Wood Dust

NIOSH 5700 provides a concentration testing method and identifies acceptable exposure levels of formaldehyde found in textile and wood dust. Formaldehyde-based resins are frequently used as adhesives for particle and fiber boards and are added to fabrics to render them wrinkle resistant. Workers in these industries are continually exposed to wood or textile dusts that slowly release formaldehyde, which poses significant health risks as a potential carcinogen.

Samples are collected using a personal sampling air pump, extracted from the filter using warm (37 °C) water, and hydrolyzed with perchloric acid to yield the corresponding hydrazone. Hydrazone concentration is then measured using HPLC with a UV detector. Caution should be exercised in the way that data collected with this method is interpreted. Results from NIOSH 5700 should be reported separately from vapor-phase formaldehyde exposure data, until sufficient data has been collected to allow for the appropriate epidemiological interpretation of formaldehyde-containing particulate exposure. Our product portfolio contains all the Millipore® filtration products you need for particle monitoring, regardless of your method or application.

Analytical Method: High performance liquid chromatography (HPLC) with UV detection
