RTD Project : F 1302
Testing method for protective gloves for PAH at renovation work

Project funded by the Bundesanstalt für Arbeitsschutz und Arbeitsmedizin (German Federal Institute for Occupational Safety and Health).

Polycyclic Aromatic Hydrocarbons (PAH) can occur as solids or paste when demolition and renovation work is undertaken. The barrier effect of protective clothing and gloves cannot be assessed by the existing standard testing methods. A new method for testing the permeation of PAH through barrier membranes was developed using essential elements of the testing standards EN 374-3, ASTM F739, and ISO 6529, but with a solid sampling medium as receptor.

Permeation tests of three undiluted tar products showed that three out of four protective gloves in test were good barriers towards PAH during at least one working day. Another glove showed a low permeation in the beginning that increased substantially. These tests showed that even higher molecular compounds such as the PAH can permeate through liquid tight elastomers. And in contrast to assumptions widely accepted in Germany, benzo(a)pyrene failed to be a marker for PAH dermal exposure because benzo(a)pyrene did not show permeation even when other PAH did.
