Effective Date Note: At 63 FR 33466, June 18, 1998, Sec. 1910.151 was amended by revising
the last sentence of paragraph (b) and by adding appendix A to the section, effective Aug. 17,
1998.
The need for access to medical services in emergencies was discussed at some length in
Chapter 1. Prompt action can frequently save an individual's life or can significantly reduce the
seriousness of injuries. Although not intended as an instruction manual, Chapter 1 presented
some first aid procedures for accidents involving chemicals and CPR techniques. It would be
highly desirable for individuals working in facilities where hazards are present to be trained in
both of these subjects. By working carefully so as not to tempt fate too much, and with a great
deal of luck, an individual may go through an entire working career without personally
experiencing an accident or being present when someone else does, but this cannot be counted
upon. Although you cannot perform CPR on yourself, and you may be incapacitated so that even
simple first aid is beyond you, if enough personnel in a laboratory do make the effort to become
trained, it is likely that someone will be available to start emergency aid while waiting for more
skilled personnel to arrive. The institution at which the author worked had an in-house volunteer
rescue squad and the members of this squad as well as the town squad were scattered throughout
the university. Although the rescue squad was normally present within 3 to 4 minutes, on several
occasions these on-scene personnel were instrumental in ameliorating severe accidents prior to
the squad’s arrival. The training for basic first aid and single-person CPR is not difficult, and
everyone should annually devote the few hours necessary to receive and maintain these skills.
Many rescue squads, fire departments, hospitals, and other public service agencies offer the
training at a minimal fee covering only the cost of the manuals and supplies.
i. Vaccinations
All of us as children probably received some vaccinations against a number of diseases. A
number of common diseases afflicting children who were born in the first third of this century
are now decreasing in frequency as a result of widespread vaccination programs. A recent
controversy centered around whether the last smallpox virus in the world, being maintained in
a laboratory, should be destroyed. Yet this used to be one of the world's great killers. Relatively
recently vaccinations for other diseases have been developed, and diseases such as polio and
measles are relatively rare now in the United States, although, unfortunately, there has been a
modest resurgence of these two illnesses. Tuberculosis is also on the rise as a consequence of
the spread of AIDS. It would appear that with the obvious benefit, vaccination against a disease
would be a matter of course, providing that a vaccine exists. This is not necessarily the case.
Several factors need to be considered in determining whether vaccination is desirable or not.
The first clearly is: Does a safe, reliable vaccine exist? At one time, rabies vaccine using duck
embryos was the best available. However, it did not always provide a reliable immunization, and
a significant fraction of the persons on which it was used had reactions, some of which were
neurologically very severe. Now, a much more reliable human diploid rabies vaccine is available
which provides protection for a very high percentage of persons, and the incidence of untoward
reactions is very low. It is probably desirable to mandate vaccination for all personnel who face
a high risk of exposure to rabies, i.e., persons who work directly with animals that might be rabid,
individuals who do necropsies on such animals, and technicians who work with untreated tissue
from potentially rabid animals. The second question is: What is the risk-benefit to the individual
if the disease is contracted? The disease may not be sufficiently serious as to warrant the risk
of a possible reaction to a vaccination. On the other hand, if the disease is sufficiently life
threatening, then the use of a vaccine would be indicated. Third: Is there a satisfactory post-
©2000 CRC Press LLC
exposure treatment? This is really critical for life-threatening diseases. If there is not, and the
exposure risk is significant, the use of even a less than totally satisfactory vaccine might well be
considered. Other considerations would be the state of the individual's health. If the condition
of the person is such that the possibility of an adverse reaction could have a strong negative
impact on the individual, then one would question the desirability of using a vaccine, but one
would also question placing such a person in an environment in which vaccination might be
considered.
Booster injections are needed for some diseases to ensure an adequate protective level of
antibodies. However, some patients may experience reactions to a booster. It is advisable to do
a blood titer test prior to repeat injections. If the titer is adequate, no booster should be
administered.
Although the laboratory supervisor should have considerable input in deciding whether a
vaccine should be used or not, any decision to institute a mandatory vaccination program should
be reviewed by a separate biosafety committee before implementation. Individuals must be fully
informed of any possible risks.

E. The OSHA Bloodborne Pathogen Standard: Infection from Work with Human Specimens
OSHA published 29 CER 1910.1030, regulating exposures to bloodborne pathogens on
December 6, 1991. The rule took effect on March 6, 1992. Under the standard, employers affected
by the standard were to be in full compliance by July 6, 1992. An exposure control plan was to
be in effect by May 5, 1992, and employee training made available by June 5, 1992. OSHA has
taken a firm posture on implementation of the rule. OSHA can impose a fine of up to $70,000 per
willful violation.
In the standard, OSHA defines bloodborne pathogen to mean “pathogenic microorganisms
that are present in human blood and can cause disease in humans.” These pathogens include,
but are not limited to, hepatitis B virus (HBV) and human immunodeficiency virus (HIV). The
emphasis has been on these two diseases, although other diseases may be found in human blood
and tissue and technically are covered. The standard also does not limit itself to human blood
despite the name. The standard includes other potentially infectious materials, which are defined
by the standard to mean (1) the following human body fluids: semen, vaginal secretions,
cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid,
saliva in dental procedures, any body fluid that is visibly contaminated with blood, and all body
fluids in situations in which it is difficult or impossible to differentiate between body fluids; (2)
any unfixed tissue or organ (other than intact skin) from a human (living or dead); and (3) HIVcontaining cell or tissue cultures, organ cultures, HIV- or HBV-containing culture medium or other
solutions, and blood, organs , or other tissues from experimental animals infected with HIV or
HBV.
The CDC published guidelines for prevention of transmission of bloodborne diseases and
©2000 CRC Press LLC
identified certain substances in which the potential for transmittal of HBV and HIV was extremely
low or nonexistent. These substances were feces, nasal secretions, sputum, sweat, tears, urine,
and vomitus, unless they contain visible blood.
When the standard was published, it was predicted that the standard would prevent
approximately 9000 infections of HBV and approximately 200 deaths per year from this disease.
Far fewer persons are known to have acquired HIV from occupational activities, less than 100
at the time the standard went into effect. By mid-1998, there have been 54 known cases of
occupationally acquired HIV infection, and an additional 133 possible cases.

Basic Provisions
There are several key components to a program to achieve compliance with the standard:
1. An exposure control plan
2. Exposure determination
The standard identifies several areas in which explicit guides are provided to assure
compliance:
1. General
2. Engineering and work practice controls
3. Personal protective equipment
4. Housekeeping
Other requirements include:
1. HBV vaccination and postexposure evaluation and follow-up
2. Communication of hazards to employees
3. Record keeping
Each of the above areas will be discussed in the following sections.
2. Exposure Control Plan
The exposure control plan is the organization's written statement of how it plans to eliminate
or minimize employee exposure. It must cover each of the broad areas listed in the previous
section.
a. Exposure Determination
The employer must compile a list of job classifications in which (a) all employees in those jobs
have occupational exposures and (b) some employees have occupational exposures. The
employer must identify a list of tasks and procedures or groups of closely related tasks and
procedures in which occupational exposure occurs and which the employees in the first two lists
perform. The lists do not take into consideration any use of personal protective equipment to
exclude personnel.
The first list in which all employees in those jobs do have occupational exposure might
include for any research-oriented organization:
