Risk för återantändning efter släckt brand. För vätskor gäller att brännbara ångor kan sprida sig, och ge explosionsrisk vid läckage inomhus eller i avlopp. Ångorna är i många fall tyngre än luften (kontrollera på Fysdata-fliken!) och kan då samlas i lågt belägna utrymmen, t.ex. källare. Pentylene Glycol, 1,2-Hexanediol and Caprylyl Glycol are 1,2-glycol compounds that vary only by the number of carbons.
