Disinfection- Sterilization-Decontamination

 

LEARNING RESULTS

The aim of the course is to train students to implement preventive and repressive measures to combat microorganisms.

The aim of the course for the students is to acquire the skills that will help them in organizing and executing and in controlling the effectiveness of integrated applications of disinfection, antiseptic and decontamination in home and professional spaces. After the end of the course students will be able to:

• evaluate and look for the supplements required in the disinfection questions and luggage in home color and professional
•  always organize and run on household money and applications that require disinfection and sterilization·        attract results from the results and characteristics of disinfection, antiseptic, abstinence and exit.
