Inactivation of pathogenic agents from blood on equipment and in the environment

The emergence of HIV raised awareness concerning all of the pathogenic microorganisms that are transmitted through blood. However, national and international recommendations related to the elimination of these germs on the surfaces of the environment do not seem to be very useful.

Studies conducted on disinfectants point out that an immersion time of 10 minutes is required. However, items such as equipment, floors and beds cannot be submerged. On the other hand, the majority of disinfectants become inactivated in the presence of organic matter and if some of their concentrations are increased, they can be caustic or toxic.

Alternatively, it would be advisable to use chlorine-based products to carry out cleaning of equipment and the environment, resulting in early elimination of blood and visible dirt. This practice also eliminates viruses and reduces the time, corrosion and toxicity of the disinfection process.

Blood and dirt can also be eliminated by first cleaning and later using alcohol 70% for disinfection.

The adequate selection of the disinfectant will depend on: the type of element, the corrosion factors and the possibilities of submerging the element. In general, the recommendations are regulated in the following manner:

Eliminate or minimize the risk of occupational exposure to pathogenic microbes that are transmitted through the blood by first cleaning and then decontaminating with an appropriate disinfectant.
