Gas on Hand

This is one of the few studies on the subject:

Gasoline on Hands: Preliminary Study on Collection and Persistence,” Melinda Darrer, Joelle Jacquemet-Papilloud, and Olivier Delemont, Forensic Science International, vol. 175, no. 2, March 5, 2008, pp. 171–8. [AIR 16:2] (Thanks to Tom Gill for bringing this to our attention.) The authors, who are respectively at the Police Cantonale Vaudoise in Lausanne, Switzerland, at the Police Cantonale Valaisanne in Sion, and at the University of Lausanne, report:

[A] first study was undertaken to evaluate a simple, fast and efficient method for collecting gasoline from hands, and to assess its persistence over time… A statistical assessment of the results indicates that latex and PVC gloves worn for about 20 min, as well as paper filter rubbed on hands, allow an efficient collection of gasoline applied to hands
