Transcript Annual Biosafety Training 2002

Everyone is responsible for keeping
the environment safe and effective—
this means you!!!!!
What does biosafety mean??
 Biosafety refers to the protection of
persons whose jobs put them at a
reasonable risk of coming into contact
with blood and other potentially
infectious materials
OSHA Bloodborne Pathogens
Standard
 1991 Bloodborne Pathogen Standard
 This standard is an excellent guide that details what
employers must do to protect their workers whose jobs
put them at a reasonable risk of coming into contact
with blood and other potentially infectious materials.
How do we protect ourselves?
Standard Precautions
 Treat ALL body fluids
and substances as
potentially infectious
Bloodborne Transmission
 Some pathogens are transmitted primarily
through blood
 Transmission occurs through sticks, splashes, or
sprays
 CDC estimates 600,000 to 800,000 injuries occur
annually
 1000 needle sticks occur every day
 385,000 needle sticks occur annually, reported
Bloodborne Transmission
 The following are examples
of Bloodborne pathogens
that can be transmitted by
sticks, splashes and sprays
 HIV- Human
Immunodeficiency Virus
 HBV- Hepatitis B Virus
 HCV- Hepatitis C Virus
Respiratory Transmission
 Some pathogens are transmitted primarily through
respiratory droplets:
 Coughing
 Sneezing
 Touching respiratory drops on yourself, another person,
or an object, and then touching mucus membranes (e.g.
mouth, nose, eyes) without washing hands
Respiratory Transmission
 Influenza virus is transmitted from person–toperson through respiratory transmission.
 Influenza is not spread by food.
 You cannot get H1N1 Influenza (Swine flu) from
eating pork or pork products.

If Influenza Is Suspected





Patients should be instructed to cover the nose/mouth
when coughing or sneezing.
Tissues should be provided to patients and visitors to
contain respiratory secretions.
Waste receptacles will be positioned in convenient
locations to facilitate proper disposal of contaminated
tissues.
Alcohol-based hand gel and hand hygiene supplies
should be available for patients
and visitors to utilize.
Masks should be available and offered to persons who are
coughing.
If Influenza Is Suspected
 The patient should be placed directly into an
individual room with the door kept closed.
 Medical personnel entering the room of a patient
in isolation should be limited to those performing
direct patient care.
 If a room is not immediately available, the patient
should be given a surgical mask and seated at
least 6 feet from other clients and staff.
If Influenza Is Suspected
 Procedures that are likely to generate aerosols
(e.g., suctioning, administering nebulized
medications) should not be performed on patients
with suspected Influenza infection.
 Suspected or known influenza patients should not
be referred to Dental Clinics, WIC offices, or other
services during the illness.
Knowledge Assessment
If influenza is suspected…
 A. Tissues should be provided to
patients and visitors to contain
respiratory secretions.
 B. The patient should be placed
directly in a room or seated 6
feet from other patients.
 C. Suspected or known
influenza patients should not be
referred for dental or WIC
services.
 D. All of the above
Answer
 D. All of the above
If SCABIES IS SUSPECTED
 Scabies is easily spread by close personal contact
and by contact with bedding and clothing
 The patient should be placed directly into an
individual room with the door kept closed.
 Suspected or known Scabies patients should not
be referred to Dental Clinics, WIC offices, or other
services during the illness.
How Do We Protect Ourselves?
Personal Protective Equipment
(PPE)
 Select masks, goggles, face shields, and combinations of
each according to the need anticipated by the task
performed.
 Wear a gown, that is appropriate to the task, to protect
skin and prevent soiling or contamination of clothing
during procedures and patient-care activities when
contact with blood, body fluids, secretions, or
excretions is anticipated.
 Wear gloves when it can be reasonably anticipated that
contact with blood or other potentially infectious
materials, mucous membranes, non-intact skin, or
potentially contaminated intact skin (e.g., of a patient
incontinent of stool or urine) could occur.
How To Don A Surgical Mask
1. Place over nose,
mouth, and chin
2. Fit flexible nose piece
over nose bridge
3. Secure on head with
ties or elastic
4. Adjust to fit
How To Don Eye And Face
Protection
1. Position goggles over eyes
and secure to the head using
the ear pieces or headband
2. Position face shield over
face and secure on brow
with headband
3. Adjust to fit comfortably
How To Don Gloves
1. Don gloves last
2. Select correct type and size
3. Insert hands into gloves
4. Extend gloves over lab coat cuffs
How To Safely Use PPE
 Perform hand hygiene before donning new gloves
 Keep gloved hands away from face
 Avoid touching or adjusting other PPE
 Limit surfaces and items touched
 Remove gloves if they become torn
Sequence For Removing PPE
Remove gloves
2. Remove face shield or goggles
3. Remove lab coat
4. Remove mask
1.
Knowledge Assessment
PPE should be worn…
 A. Anytime there is a risk of
exposure to skin, clothes,
eyes, mouth or other mucous
membranes.

How Do We Protect Ourselves?
Engineering Controls
 Physical or mechanical systems provided to eliminate
hazards
 Examples:
 Sharps containers
 Safety needle devices (safety lancets, self-retracting
vacutainers, butterflies with self-retracting needles
 Bio-hazard refrigerators
 Signage identifying bio-hazard refrigerators (NOT FOR
FOOD OR DRINK)
 Red biohazard leak proof bags

How Do We Protect Ourselves?
Work Practice Controls
 “Work Practice Control” refers to altering or changing
the way YOU perform a task to accomplish the task in
the safest way possible
Work Practice Controls
 Examples include:
 Handling of specimens to
minimize potential splash,
spray or splatter
 Safe needle usage (one
handed technique to
activate safety device) and
disposal
 Using spill kits to remove
spilled specimens
Work Practice Controls - Dental
 Examples include:
 Using instruments instead of fingers to retract tissues
 Passing instruments with sharp ends
pointing away
 Safe needle usage and disposal
(mechanical device to
facilitate one-handed recapping
when re-sheathing aspirating
syringe needles)
 Using spill kits to remove spilled
specimens
 Personal hygiene and work habits
Work Practice Controls- Dental
 All dental devices connected to the dental
air/water system that enters the patient’s
mouth must be run to discharge water, air
or a combination for a minimum of 20-30
seconds after each patient. This
procedure is intended to flush out patient
material
 Flushing out waterlines at the end of each
clinical day with a chemical disinfectant.
The disinfectant will be left in the
waterlines overnight and flushed at the
beginning of each clinical day
Work Practice Controls
 Personal hygiene and
work habits
 Cotton balls, Q-tips,
and tongue depressors
must be covered!!!!
Work Practice Controls
 Personal Items should be very minimum
 No decorative items, personal lamps, etc
 Do not tape, tack or pin items on walls or doors
 Remember a patient care area is for the provision of
health care – not an “office”
 NO FOOD OR DRINK!!
Work Practice Controls
Consumable Items:
 NO food or drink present or stored in patient care
areas including:
 Exam rooms
 Nutrition and Social Services offices
 Interview Areas
 Patient Registration
Remember you are protecting yourself!!

drinking in patient care areas
 C. Covering containers of
cotton balls
 D. All of the above
Answer
