Who Is Covered?
Healthcare facilities provide an environment conducive
to the spread of infectious diseases. Healthcare
professionals must understand and carry out their
role in protecting patients and themselves from
infectious agents with adherence to the established
infection control practice as required and set
fourth by The Occupational Safety and Health Administration
(OSHA). This in-service will verse you in
OSHA’s Guidelines on contamination, Hepatitis
B Vaccine, reporting exposures, personal protective
equipment and handling contaminated sharps.
"Occupational exposure" means a reasonably
anticipated skin, eye, mucous membrane, or parenteral
contact with blood or “other potentially
infectious materials” (OPIM) that may result
from the performance of the employee's duties. "Bloodborne
pathogens" means pathogenic microorganisms
present in human blood that can cause disease. "Other
potentially infectious materials” include
certain human body fluids, including saliva in
dental procedures, and any body fluid visibly contaminated
with blood. The Bloodborne pathogens standard describes
how to determine who is covered and the ways to
reduce workplace exposure to Bloodborne pathogens.
The first step is a written exposure control plan.
Exposure Control Plan
As required under the standard, a written exposure
control plan is required that provides documentation
of the following key elements:
- Identification of job classifications and, in some cases, tasks where
there is exposure to blood and other potentially infectious materials.
- A schedule of how and when the provisions of the standard will be implemented,
including schedules and methods for communication of hazards to employees,
hepatitis B vaccination and post-exposure evaluation and follow-up, record
keeping and implementation of the methods of compliance, such as
—Engineering and work practice controls,
—Personal protective equipment,
—Housekeeping, and
- Procedures for evaluating the circumstances of an exposure incident.
The schedule of how and when the provisions of
the standard will be implemented may be a calendar
with brief notations describing the methods, or
an annotated copy of the standard, or part of another
document, such as the infection control plan.
The written exposure control plan must be accessible
to employees and must be updated at least annually
and when alterations in procedures create new occupational
exposure. Planning begins with identifying employees
who have occupational exposure.
Who Has Occupational Exposure?
The exposure determination must be based on the
definition of occupational exposure without regard
to the use of personal protective clothing and
equipment. Reviewing job classifications within
the practice setting, and then making a list divided
into two groups makes the exposure determination.
The first group includes job classifications in
which all of the employees have occupational exposure,
such as clinical dental hygienists. Where all employees
have occupational exposure, it is not necessary
to list specific work tasks. The second group includes
those classifications in which some of the employees
have occupational exposure. Where only some employees
have exposure, specific tasks and procedures or
groups of tasks and procedures causing exposure
must be listed. An example would be a dental practice
with two or more receptionists, where one of the
receptionists might be assigned the task of filling
in for the dental assistant. When employees with
occupational exposure have been identified, the
next step is to communicate the hazards to these
employees.
Communicating Hazards to Employees
The initial training for dental employees must
be provided within 90 days of the effective date
of the Bloodborne pathogens standard, at no cost
to the employee, and during working hours. Training
is also required for new employees at the time
of initial assignment to tasks with occupational
exposure or when job tasks change, causing a change
in occupational exposure. Annual retraining for
all affected employees must be provided. If employees
have received training on Bloodborne pathogens
in the year preceding the standard, only training
in those areas required by the standard and which
was not included in the previous training needs
to be provided. This training could be included
in training on other aspects of office safety,
such as infection control and chemical hazards.
Training sessions must be comprehensive in nature,
yet appropriate for the educational level, literacy,
and language of employees, and provide the opportunity
for interactive questions and answers. The person
conducting the training must be knowledgeable in
the program components as they relate to dentistry.
Specifically, the training program, as a minimum,
must include the following:
- An accessible copy of the regulatory text
of the standard and an explanation of its content.
- An explanation of the epidemiology and symptoms of Bloodborne diseases.
- An explanation of the modes of transmission of Bloodborne pathogens;
- An explanation of the employer's written exposure control plan and how
to obtain a copy.
- How to recognize occupational exposure;
- The methods to control occupational transmission of Bloodborne pathogens;
- How to select, use, remove, handle, decontaminate, and dispose of personal
protective clothing and equipment;
- Information on the hepatitis B vaccine and vaccination, the availability
of vaccine, and that vaccination is available at no cost to the employee.
- Information on emergencies involving blood and other potentially infectious
materials;
- an explanation of the reporting mechanisms for exposure incidents.
- Information on the post-exposure evaluation and follow-up available
by a health care professional when an exposure incident occurs;
- an explanation of labels, signs, and other markings for contaminated
materials, such as instruments and laundry; and
- A question and answer session on any aspects of the training.
In addition to communicating hazards to dental
employees and providing training to identify and
control hazards, other preventive measures must
be taken to ensure employee protection.
Preventive measures such as hepatitis B vaccination,
universal precautions, engineering controls, safe
work practices, personal protective equipment,
and housekeeping measures help reduce the risks
of occupational exposure.
The Needlestick Safety and Prevention Act requires
employers, who have exposure control plans in accordance
with 1910.1030 © (1) (iv), “to review
and update such plans to reflect changes in technology
that eliminate or reduce exposure to Bloodborne
pathogens.” The exposure control plan
must also “document consideration and implementation
of appropriate commercially available and effective
safer medical devices designed to eliminate or
minimize occupational exposure.” Employers
required to have exposure control plans must also “solicit
input from non-managerial employees responsible
for direct patient care who are potentially exposed
to injuries from contaminated sharps in the identification,
evaluation, and selection of effective engineering
and work practice controls and shall document the
solicitation in the Exposure Control Plan.” The
Needlestick Safety and Prevention Act also require
employers, who currently maintain a log of occupational
injuries and illnesses under 29 CFR 1904, to “establish
and maintain a sharps injury log for the recording
of percutaneous injuries from contaminated sharps.” The
information in the sharps injury log must be recorded
and maintained so that the confidentiality of the
injured worker is protected. The log must
contain at least the following information: “(A)
the type and brand of device involved in the incident;
(B) the department or work area where the exposure
incident occurred; and (C) an explanation of how
the incident occurred.”
Preventive Measures Hepatitis B Vaccination
Treatment
Hepatitis B vaccination must be made available within
10 working days of initial assignment to every employee
whose job classification or tasks result in occupational
exposure. Hepatitis B vaccination and vaccine must
be made available without cost to the employee, at
a reasonable time and place for the employee, and
by or under the supervision of a licensed health
care professional. * The employer must provide the
health care professional with a copy of the Bloodborne
pathogens standard. The health care professional
will provide the employer with a written opinion,
which is limited to stating whether hepatitis B vaccination
is indicated for the employee or if the employee
has received such vaccination. Employers are not
required to offer hepatitis B vaccination (a) to
employees who have previously completed the hepatitis
B vaccination series, (b) when immunity is confirmed
through antibody testing, or (c) if the vaccine is
contraindicated for medical reasons. Employees may
decline antibody testing and still be vaccinated.
Following appropriate training about hepatitis B
and vaccination, employees who still decline the
vaccination must sign a statement to that effect
(see Appendix A). Employees who continue to be at
occupational risk for hepatitis B may request and
obtain the vaccination at a later date. The hepatitis
B vaccination series must be administered according
to the current guidelines of the U.S. Public Health
Service, including recommendations made in the future
for routine booster doses. (For current information
on the U.S. Public Health Service's recommendations
on hepatitis B vaccination, dentists may call the
Centers for Disease Control: DISEASE INFORMATION
HOTLINE (404) 332-4555.)
*A person, such as a physician or nurse practitioner,
whose legal scope of practice allows them to perform
the hepatitis B vaccination and post-exposure and
follow-up required in the standard.
Universal Precautions
The single most important measure to control
transmission of HBV and HIV is to treat all human
blood and other potentially infectious materials
AS IF THEY WERE infectious for HBV and HIV. Application
of this approach to infection control is referred
to as "Universal Precautions." Blood
and saliva from all dental patients are considered
potentially infectious materials [2]. These fluids
cause contamination defined in the standard as, "the
presence or the reasonably anticipated presence
of blood or other potentially infectious materials
on an item or surface."
Control Measures
Engineering and work practice controls are the
primary methods used to control the transmission
of HBV and HIV in the dental setting. Personal
protective clothing and equipment are also
necessary when occupational exposure to Bloodborne
pathogens remains even after instituting these
controls.
Engineering controls, as they apply to the
dental operatory, isolate or remove the hazard from employees. Rubber dams,
high-speed evacuators, and special containers for contaminated sharp instruments
are examples of engineering controls. Engineering controls must be examined
and maintained, or replaced, on a scheduled basis. These engineering controls
are used in combination with work practice controls.
Work practice controls reduce the likelihood of exposure
by altering the manner in which the task is performed. All procedures must
be performed in such a manner as to minimize splashing, spraying, spattering,
and generating droplets of blood or other potentially infectious materials.
This can be as simple as readjusting the position of the dental chair. Work
practice requirements include the following:
- Washing hands immediately, or as soon as feasible, after skin contact
with blood or other potentially infectious materials occurs and after removing
gloves or other personal protective equipment;
- Flushing mucous membranes immediately or as soon as feasible if they
are splashed with blood or other potentially infectious materials;
- Prohibiting recapping, bending,
or removing contaminated needles from syringes—unless
required by the dental or medical procedure
or no alternative is feasible—in which
case must be done by mechanical means, such
as the use of forceps, or using a one-handed
technique. For example, recapping is permitted
when administering multiple injections of
local anesthesia.
- Eliminating the shearing and breaking
of contaminated needles
- Discarding contaminated needles,
disposable sharps (such as endodontic files
or dental wires with exposed ends) in containers
that are closable, puncture-resistant, leak
proof, colored red or labeled with the biohazard
symbol*shown in Figure 1. (These containers
must be easily accessible, maintained upright,
and not allowed to overfill);
- Placing contaminated, reusable sharp
instruments in containers that are puncture-resistant,
leak proof, colored red or labeled with the
biohazard symbol until properly processed.
(Reusable sharps must not be
stored or processed in such a way that employees
are required to reach by hand into
the container to retrieve the instruments);
- Prohibiting eating, drinking, smoking,
applying cosmetics, and handling contact
lenses in areas where there is occupational
exposure, such as in a dental operatory or
reprocessing areas;
- Eliminating the storage of food
and drink in refrigerators, cabinets or shelves,
or on counter-tops where blood or other potentially
infectious materials are present; and
- Storing, transporting, or shipping
blood or other potentially infectious materials—such
as extracted teeth, tissue, and impressions
that have not been decontaminated—in
containers that are closed, prevent leakage,
colored red, or affixed with the biohazard
label.
- In addition to instituting engineering
and work practice controls, the standard
requires that appropriate personal protective
equipment also be used to reduce worker risk
of exposure.
'Labeling requires a fluorescent orange or
orange-red label with the biological hazard
symbol, along with the word "BIOHAZARD" in
a contrasting color, affixed to the bag or container.

Figure 1 Biohazard Symbol
Personal Protective Equipment
Personal protective equipment is
specialized clothing or equipment worn by employees
to protect themselves from exposure to blood or
other potentially infectious materials. Personal
protective equipment must not allow blood or other
potentially infectious materials to pass through
to clothing, skin, or mucous membranes.
The employer has the following responsibility for personal protective equipment,
at the employer's expense:
- Providing, maintaining, and replacing;
- Ensuring accessibility in appropriate sizes;
- Providing hypoallergenic gloves, glove liners, powderless gloves
or other similar alternatives if the employee has an allergy to the gloves
usually provided;
- Ensuring employee use; and
- Laundering and discarding.
Gloves, clinic jackets, lab coats, and chin-length
face shields, or the combination of masks with
eye protection (such as glasses with solid side
shields or goggles) must be worn whenever splashes,
spray, spatter, or droplets of blood or other infectious
materials may be generated. Cotton or cotton/polyester
clinic jackets or lab coats are usually satisfactory
barriers for routine dental procedures.
When surgical procedures are performed involving
large quantities of blood, additional personal
protective equipment is required. Remember:
The selection of appropriate personal protective
equipment is based upon the quantity and type of
exposure expected.
Requirements for personal protective equipment
also include the following:
- Face protection can be accomplished
using a chin-length face shield or a combination
of mask with eye protection.
- Goggles or eye glasses with
solid side shields or face shields can provide
adequate eye protection.
- Clinic jackets, lab coats, gowns,
and other protective clothing and equipment
must be removed immediately or as soon as feasible
when penetrated by blood or other infectious
materials, and prior to leaving the work area.
- Gloves must be worn when it is reasonably
anticipated that an employee will have hand
contact with blood or saliva during procedures;
when performing vascular access procedures;
or when handling instruments, materials, and
surfaces that are contaminated.
- Disposable gloves must be replaced
upon the completion of the dental procedure,
or if torn or punctured during the procedure.
- Disposable gloves are not to be reused.
- Utility gloves used for cleanup may
be decontaminated for reuse, but must be discarded
if they are deteriorated or fail to function
as a barrier.
- Contaminated personal protective equipment
must be placed in an appropriately designated
area or container for storing, washing, decontaminating,
or discarding.
Housekeeping
Equipment. The employer
must ensure a clean and sanitary workplace. Work
surfaces, equipment, and other reusable items
must be decontaminated with disinfectant upon
completion of procedures when contamination occurs
through splashes, spills, or other contact with
blood and other potentially infectious materials.
If surfaces, equipment, and other items (such
as light handles or trays) have been protected
with coverings (such as plastic wrap or foil),
these materials must be replaced when contaminated
or at the end of the work shift. Reusable receptacles
such as bins, pails, and cans that have a likelihood
for becoming contaminated, must be inspected
and decontaminated on a regular basis and when
visibly contaminated. Broken glass that may be
contaminated may be cleaned up with a brush or
tongs; but never picked up with hands, even if
gloves are worn.
Equipment that has had contact with blood or other potentially infectious materials
and serviced either on-site or shipped out of the facility for maintenance or
other service, must be decontaminated to the extent feasible or labeled as a
biohazard indicating which parts were not able to be decontaminated.
Waste. A combination of local, state, and federal laws
may regulate waste removed from the facility. To comply with the Bloodborne pathogens
standard special precautions are necessary when disposing of contaminated sharps
and other regulated waste. *
Contaminated disposable sharps must be placed in containers that are closable,
puncture resistant, leak proof, and are colored red or labeled. Other regulated
waste generated from dental procedures also must be contained in closable bags
or containers that prevent leakage and are colored red or labeled. A secondary
container is necessary for containers that are contaminated on the outside. The
secondary container also must be closable, prevent leakage, and be color-coded
or labeled (see Table 2).
Laundry. Contaminated laundry shall be handled as little
as possible with minimum agitation. Laundering contaminated articles, including
employee clinic jackets and lab coats used as personal protective equipment,
is the responsibility of the employer. This can be accomplished through the use
of a washer and dryer in a designated area on-site, or the contaminated articles
can be sent to a commercial laundry that processes contaminated laundry.
'Liquid or semi-liquid blood or other potentially
infectious materials; items contaminated with
blood or other potentially infectious materials
that would release these substances in a liquid
or semi-liquid state if compressed; items that
are caked with dried blood or other potentially
infectious materials and are capable of releasing
these materials during handling; contaminated
sharps; and pathological and microbiological
wastes containing blood or other potentially
infectious materials. Alternative labeling or
color-coding is sufficient if it permits all
employees to recognize the containers as requiring
compliance with Universal Precautions.
The care and laundering of general work clothes,
for example, uniforms used to provide a professional
appearance and not used as personal protective
equipment, are not the responsibility of the
employer.
- Contaminated laundry must be placed in bags
or containers that are red or that are marked
with the biohazard symbol. If the office uses Universal
Precautions in handling all soiled
laundry, alternative labeling is permitted,
provided that all employees are appropriately
trained and recognize that the bags contain
contaminated laundry.
- if the laundry is sent off site for cleaning,
it must be in bags or containers that are clearly
marked with the biohazard symbol, unless the
laundry facility utilizes Universal Precautions in
the handling of all soiled laundry.
- if contaminated laundry is wet, the bags
or containers must prevent leakage and soak-through.
- Gloves and other appropriate personal protective
equipment must always be worn when handling
contaminated laundry.
As already indicated, the above preventive measures
are intended to eliminate or minimize the risks
of occupational exposure in dental facilities.
In the event that an exposure incident occurs,
however, there are certain required procedures
to use.
What to do if an Exposure Incident
Occurs
An exposure incident is a specific eye, mouth, other mucous membrane, non-intact
skin, or parenteral contact with blood or other potentially infectious materials
that results from the performance of an employee's duties. An example of an exposure
incident would include a puncture from a contaminated sharp instrument.
The employer is responsible for establishing the procedure for evaluating exposure
incidents. When evaluating an exposure incident, thorough assessment and confidentiality
are critical issues. Employees should immediately report exposure incidents to
their employer to initiate a timely follow-up process by a health care professional.
Such a report initiates the procedure for a prompt request for evaluation of
the source individual's HBV and HIV status. The employee who has had an exposure
incident must be directed to a health care professional. The employer must provide
the health care professional with a copy of the Bloodborne pathogens standard.
A description of the employee's job duties as they relate to the I
incident; a report of the specific exposure incident (accident report), including
routes of exposure; the results of the source individual's blood tests, if available;
and relevant employee medical records, including their vaccination status. At
that time, a baseline blood test to establish the employee's HIV and HBV status
will be drawn, if the employee consents. The employee has the right to decline
testing or to delay HIV testing for up to 90 days. During this time, the health
care professional must preserve the employee's blood sample.
The "source individual" is any patient whose blood or body fluids is
the source of an exposure incident to the employee. Testing the;
Source individual's blood cannot be done in most states without written consent.
The results of the source individual's blood tests are confidential and should
be directed only to the attending health care professional.
As soon as possible, test results of the source individual's blood must be made
available to the exposed employee through consultation with the health care professional.
Following the post-exposure evaluation, the health care professional will provide
a written opinion to the employer. This opinion is limited to a statement that
the employee has been informed of the results of the evaluation and told of the
need, if any, for further evaluation or treatment. All other findings are confidential.
The employer must provide a copy of the written opinion to the employee within
15 days of the evaluation. Requirements for the medical record and training records
are discussed in the next section on recordkeeping.
Recordkeeping
There are two types of employee-related records required by the Bloodborne pathogens
standard: medical and training.
A medical record must be established for each employee withoccupational exposure.
This record is confidential and separate from other personnel records. This record
may be kept on-site or may be retained by the health care professional that provides
services to the dental health care employees. The medical record contains the
hepatitis B vaccination status, including the dates of the hepatitis B vaccination
and the written opinion of the health care professional regarding the hepatitis
B vaccination.
If an occupational exposure incident occurs, reports are added to the medical
record to document the incident and the results of testing following the incident,
as well as the written opinion of the health care
Professional. The medical record also must indicate what documents have been
provided to the health care provider. Medical records must be maintained 30 years
past the last date of employment of the employee.
The confidentiality of medical records must be emphasized. No
medical record or part of a medical record is to be disclosed except
to the employee or anyone having written consent of the employee; to representatives
of the Secretary of Labor, upon request; or as required or permitted by state
or federal law.
Training records document each training session and must be kept by the employer
for 3 years. Training records must include the date of the training, a content
outline, the trainer's name and qualifications, and names and job titles of all
persons attending the training sessions.
If the employer ceases to do business, medical and training records are transferred
to the successor employer. If there is no successor employer, the employer must
notify the Director of the National Institute for Occupational Safety and Health,
U.S. Department of Health and Human Services, for specific directions regarding
disposition of the records at least 3 months prior to their intended disposal.
Upon request, both medical and training records must be made available to the
Assistant Secretary of Labor, Occupational Safety and Health. Training records
must be available to employees or employee representatives upon request. The
employee or anyone having the employee’s written consent can obtain medical
records.
New Information regarding BBP Standard
OSHA estimates that almost 600,000 Needlesticks occur each year among our
nation’s 5.6 million healthcare workers. In response to this President
Clinton signed the “Needlestick Safety and Prevention Act (H.R. 5178)
into law on November 6, 2000 to be published in the spring of 2001 in the Federal
Register. Below are the four easy steps to compliance:
- Make a list of all sharps used in your workplace and locate alternate “safe
sharps”
- Have front line employees evaluate “safe sharps” for effectiveness-Document
findings
- Put the sharps evaluation into the OSHA Manual. Train workers to use new
products.
- Complete a sharps injury log whenever a needlestick occurs to track problematic
devices.
