Hand contact represents the number one method of
infection transmission.
Handwashing
Hands should always be washed at the following times:
before patient contact,
when gloves are removed
prior to leaving the work area
whenever the hands have been knowingly contaminated
before going to designated break areas
before and after using bathroom facilities.
Soap to use in handwashing
Antimicrobial soap
How many seconds or mins in handwashing

What song you can use in hanwashing how many repetition
Happy birthday- 3x
When rinsing your hand the position should be
Downward position
With these type of viruses, we should have
now a strict adherence or guidelines published by

Universal precaution The guidelines recommend:
Wearing gloves
Wearing faceshield
Proper disposal of needle and sharps
Major disadvantage of Body substance isolation
Do not recommend handwashing after removal of gloves unless visual contact
BSI GUIDELINES:
Not limited blood borne pathogens
Wear gloves or personal protective equipment
Considered all body fluid or moist body substances as potentially infectious

made of glass, metal, or
plastic with a positive (screw-on) cap.
Watertight primary container
Watertight primary container must be made of
glass
metal
plastic with a positive (screw-on) cap.
must be wrapped with enough
absorbent material to be capable of absorbing all of its
contents. Multiple specimens must be wrapped
individually prior to placing them in the leak-proof
secondary container.
Primary container
is placed in a sturdy outer
container made of corrugated fiberboard, wood, metal,
or rigid plastic. An itemized list of contents in a sealed
plastic bag is also placed in the outer container. Ice
packs are placed between the secondary and the outer
container. Additional measures must be taken when
using ice and dry ice.
Secondary container
During what year and date labeling of the outer container
changed.
January 2007
The terms clinical specimen and diagnostic
specimen have been replaced with
UN 3373 biological substances, Category B.
The scope of this can be human or animal
material, including blood and its components,
but it is not limited to the blood. This also deals
with the tissue fluids or body parts.
Un 3373 biological substance, category b
Sharp objects in the laboratory, including needles,
lancets, and broken glassware, present a serious
biological hazard for possible exposure to blood borne
pathogens caused by accidental puncture.
Sharp hazard
The number-one personal safety rule when handling
needles are to never__________ one.
Never manually recap
must be disposed of in puncture-resistant,
leak-proof containers labeled with the biohazard
symbol.
Sharps
Proper pouring of acid and water
Acid to water
When skin or eye contact occurs: immediately flush the
area with water for at least ____ minutes and seek
medical attention.
15 minutes
when chemical splashes in the eye it used.
Boric acid
provides a soothing relief
from eye irritation and helps remove pollutants
from the eye, such as the smug chlorine or
other chemicals.
