they are very essential to governing agencies in terms when
it comes to the guidelines.
Center for Disease Control
and Prevention (CDC) and of course we have the
Occupational Safety and Health Administration (OSHA)
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,
and before and after using bathroom
facilities.
In ___ CDC instituted the Universal Precautions (UP).
1987
The guidelines recommend in UP:
Wearing of gloves when collecting or handling
blood and other body fluids contaminated with blood.
Wearing face shields when there is danger of
blood splashing on mucous membranes
When disposing of all needles and sharp
objects in puncture resistant containers.
Are not limited to blood-borne pathogens.
BODY SUBSTANCE ISOLATION GUIDELINES
Personnel should always wear gloves at all times when
encountering moist body substances
BODY SUBSTANCE ISOLATION GUIDELINES
A major disadvantage of __ is that, they do
not recommend handwashing following removal of gloves
unless visual contamination is present.
BSI guidelines
In __: CDC combined the major features of UP and BSI
guidelines and called the new guidelines as STANDARD
PRECAUTIONS
1996
Under this guideline standard precautions,
includes
▪ Handwashing
▪ Gloves
▪ Mask, eye protection and face shields
▪ Lab gown
Patient care equipment:
▪ Environmental control
▪ Linen
▪ Occupational health and Blood-borne
pathogens
▪ Patient Placement
Regulations for packaging and labeling developed by the
U.S. Department of Transportation (DOT),
the International Air Transport Association (IATA), and the United Nations
___ containers made of glass, metal, or plastic with a positive (screw-on) cap
Watertight primary
The __ container must be wrapped with enough
absorbent material to be capable of absorbing all of its
contents

prior to placing them in the leak-proof secondary
container.
individually
The _____ container is placed in a sturdy outer
container made of corrugated fiberboard, wood, metal,
or rigid plastic
secondary
In ___, labeling of the outer container changed.
The terms clinical specimen and diagnostic specimen have
been replaced with biological substances, Category B.
January 2007
biological substances, Category B title is placed next to the label ___.
UN 3373
NFPA stands for
national fire protection association
Disposal of radioactive waste is regulated by the __
Nuclear Regulatory Commission (NRC).
___ are the most frequently
encountered radio label
