The workwear in a retirement home is worn daily, while physically stressed and polluted. Proper laundry care in an in-house laundry is provided by the professional STAHL laundry machines. They are the basis for a safe disinfection of workwear. This is especially necessary if there is a risk of contamination with pathogens. Washing work clothes in-house protects not only the employees and their families against pathogens in nursing homes, but also the residents. Taking care of working clothes in the home with household washing machines is a risk. Namely, the household appliances do not guarantee a defined temperature maintenance time, as it is necessary for a disinfection. It can get pathogens into the home environment. Due to insufficient infection prophylaxis there is even a high risk of contamination.
