Abstract: An odor filter for exhauster hoods, which filter includes an adsorption filter bed regenerable by washing. The filter bed is made of a highly air-permeable substrate material and an adsorbent affixed thereto in the amount of 50 to 400 g/l by an adhesive mass and has a mean particle diameter between 0.2 and 2 mm.
Abstract: The present invention relates to a process for the decontamination of chemical warfare agents which are present on the skin or have penetrated below the surface into the skin, or materials contaminated therewith, by a micro-emulsion which contains a C.sub.8 -C.sub.14 alkane, an anionic surfactant, an aliphatic C.sub.3 -C.sub.10 alcohol, and water, and to which possibly a wetting agent and/or antifreeze components such as antifreeze agents, NaCl or CaCl.sub.2 are also added.
