We have installed a Purell Hand Sanitizer in the room to provide additional protection. We routinely use a disinfectant ( what hair salons put their combs and brushes in when not in use) headphones so that hair lice do not create problems and as well wipe all surfaces with Lysol on a regular basis. We use MB Quart Head sets with replaceable ear pads. Although the headsets cost $130 Canadian each, we have had these in use since the late 1970's and other than changing ear pads as they wear out, they do not fail. The disinfectant will destroy the ear pads if the disinfectant is applied and not rinsed afterwards with clear water. Our procedure is to go through the lab, treat the ear pads, then go through a second time and rinse the ear pads with clear water. Ear pads made with foam rubber will break down very quickly and even rinsing them with water still results in the ear pads disintegrating.
