WHAT IS AN MSDS
MATERIAL SAFETY DATA SHEET
Suppliers are required to provide labels for and on containers and a material safety data sheet for hazardous substances they supply.
![Page 6: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/6.jpg)

INFECTION
The invasion of the body by pathogenic agents with the subsequent multiplication and production of disease
![Page 9: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/9.jpg)
NOSOCOMIAL INFECTION

MICROBIOLOGY
The study of micro-organisms too small to be seen without the aid of a microscope.
![Page 11: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/11.jpg)

PATHOGEN
A disease producing agent usually restricted to a living agent.
![Page 13: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/13.jpg)

Free from micro-organisms
![Page 14: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/14.jpg)
DISINFECTION
A process that eliminates many or all micro-organisms except bacterial spores.
![Page 15: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/15.jpg)
STERILISATION
Is the destruction of all living organisms, including spores.
Eg. Steam under pressure
Dry heat sterilisation
Flash sterilisation
![Page 16: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/16.jpg)
COMENSAL ORGANISM
Organisms that normally live in specific sites of the body without invading the tissues or causing infection.
They are harmless in their normal site but can cause infection when transferred to an abnormal site.
Eg. Escherichia Coli aid absorption of nutrients in the intestine.
![Page 17: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/17.jpg)
OPPORTUNISTIC INFECTION
Are those which normally colonise the person’s body without causing illness, but become pathogenic when the person is susceptible.
Eg. MRSA – Methicillin Resistant Staph Aureus
VRE – Vancomycin Resistant Enterococcus
![Page 18: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/18.jpg)
STANDARD PRECAUTIONS
They apply to all patients and residents receiving care in health care facilities, regardless of their diagnosis or presumed infection status.
Eg. Handwashing
P.P.E.
Correct disposal of linen, sharps, etc.
![Page 19: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/19.jpg)
ADDITIONAL TRANSMISSION BASED PRECAUTIONS
Are designed for residents you know or suspect to be infected with pathogens for which additional precautions are needed. They are always in addition to standard precautions.
Eg. Airborne precautions
Droplet precautions
Contact precautions
![Page 20: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/20.jpg)
WINDOW PERIOD
Is the time between first infection and when a specific test can detect that infection, therefore an infected person or animal cannot be detected as infected but may still be able to infect others.
Eg. HIV window period is 3 months.
![Page 21: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/21.jpg)

![Page 24: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/24.jpg)
IDENTIFY WAYS INFECTION CAN BE SPREAD Contact – direct or indirect Droplet – sneezing, coughing, talking or
suctioning Airborne – via air current, sweeping, shaking
out linen Transmission based vectors – animals
(rats, birds, dogs, cats) or insects (mosquito, flies, ticks)
![Page 25: ELEMENTS OF COMPETENCY](https://reader035.vdocument.in/reader035/viewer/2022062315/56815be3550346895dc9d586/html5/thumbnails/25.jpg)
IDENTIFY WAYS YOU CAN BREAK THE INFECTION CYCLE USING STANDARD PRECAUTIONS – hand
washing, wearing PPE, correct disposal of contaminated items.
USING TRANSMISSION BASED PRECAUTIONS – single rooms, separate ventilation, single use or individual utensils, limiting numbers of visitors.
