Telephone headsets can be a breeding ground for dangerous and contagious bacteria that can be a cause of unnecessary ill health and absenteeism. A study conducted by the University of Arizona concluded that telephones can be contaminated with up to 25,123 germs per square inch, and that telephones have 500 times more bacteria than the average toilet seat.

The population of germs and bacteria can include E.coli, Streptococcus, Salmonella, & Staphyococcus aureus, all potentially dangerous and contagious organisms. The same bacteria can be found on telephone headset voice tubes and ear cushions, but unlike a telephone handset, these are cheap to replace and renew, making headsets a healthier alternative.

Voice tubes can also become blocked with food, make-up and dust. This is not only unhygienic, but it also compromises the effectiveness of microphones, which causes lowered volume levels for both callers and wearers, compromising their effectiveness.

Tips for headset hygiene

Issue individuals with their own headsets, or alternatively with their own voice tubes or ear cushions. Refresh voice tubes and ear cushions regularly - at leas quarterly. Train employees in correct headset hygiene procedures. Discourage staff from eating at desks, even when not wearing headsets, as bits of food can become lodged in the voice tube. Utilize anti-bacterial wipes on non-pourous surfaces such as noise canceling booms (avoiding microphones). When not in use, headsets should be stored carefully using either a desk hook, headset stand or protective bag.
