Terrorism: The New Occupational Hazard
Most of the direct victims of terrorism in the United States in recent years have
been people at work. Employers, who have a legal responsibility to provide
workplaces that are as free of “generally recognized hazards” as feasible, must
consider their exposure to this emerging threat. This report describes how workplace
safety programs are being reconsidered in this new light.
The World Trade Center site presented an immediate safety and health challenge
for public agencies and on-site workers. OSHA has jurisdiction in most disaster
situations but exercises forbearance while local emergency authorities are dealing
with rescue and recovery. This period was unusually prolonged in the World Trade
case, while workers and the general public were exposed to many toxic substances.
Special enforcement and monitoring programs were adopted there incrementally. For
the future, measures such as S. 1621 and H.R. 4687 would provide for more thorough
study and response to health impacts from such events.
General employer responsibilities that are relevant to the terrorism risk include
building and site management, workers compensation and certain aspects of
personnel policy (such as those regarding violence). In general, proper attention to
these routine matters – as modified for the new range of risks – will help assure that
all that can reasonably done in preparation will be done.
In certain high-risk industries, emergency planning is required by a number of
laws. Most facilities that use large quantities of toxic or flammable materials must
explicitly assess all potential accident modes, adapt processes to minimize them, and
plan their responses to emergencies, including coordination with local emergency
The spread of anthrax through the mail has posed unique problems for many
organizations. OSHA and the Centers for Disease Control have issued guidelines for
dealing with this and other bioterror agents in workplaces. Legislation (P.L. 107-
188) has been passed to improve overall preparedness for bioterrorism, including a
grant program to improve planning and training to protect the health of bioterror
response personnel.

Terrorism: The New Occupational Hazard
Most of the direct victims of terrorism in the United States in recent years have
been people at work, whether those in the federal building in Oklahoma City, in the
World Trade Center or the Pentagon, or victims of anthrax transmitted through the
mails. In preventing future incidents or mitigating the consequences, people may
find their most important roles as employers or employees. A survey shows that 69%
of firms had already taken tangible steps to enhance security by the end of 2001.1
The workplace is, in effect, a key line of defense for homeland security. This is
recognized formally by participation of the Department of Labor in the Homeland
Security Council established by recent Presidential directive.
Aside from general concern with the welfare of their workers and protection of
their property, employers will have a number of practical motivations for reducing
their vulnerabilities to terrorism. These consist of governmental mandates and legal
liabilities, including workers compensation. Most responsibilities are currently
generic, e.g., general fire protection, rather than protections specifically responsive
to terrorist threats. This highlights the fact that most of the practical steps businesses
can take will be found to be “dual use,” i.e., also yielding benefits in the normal
civilian context. As one commentator has suggested, “if businesses are looking for
a positive aspect of these unfathomable events, it is that they will finally start doing
all the things that ensure the safety of their employees and the continuity of their2
business that they should have been doing all along.”
This report describes workplace risks and employer responsibilities in a number
of contexts. First, there are the immediate challenges of cleaning up disaster sites,
particularly the World Trade Center. Then, we consider general standards applicable
to the measures needed to respond to terrorist incidents, e.g., building evacuation.
Finally, we describe the special risks experienced by certain industries and
occupations, such as the postal service, chemical plants, transport of hazardous
materials, and emergency response services.
World Trade Center Site
Occupational hazards abound in rescue and recovery activities at disaster sites.
These include immediate dangers associated with falls, burns, cuts and the operation
of heavy equipment, as well as longer term health risks from asbestos and toxic

substances. The World Trade Center site (WTC) presents all of these and more, in
a context of unprecedented scale, complexity and emotional ramifications.
It is the policy of the Occupational Safety and Health Administration (OSHA)
to defer to local authorities in the immediate response to catastrophic events. OSHA
will try to play a constructive role of providing technical assistance to the rescue and
recovery effort, while also collecting evidence of prior violations that may have
caused the incident. Nevertheless, the agency reserves the right to enforce safety
standards with regard to workers on site.3
Usually, the search and rescue phase will give way to stabilization and clean-up
within a couple of weeks. In the WTC case, the end of the rescue and recovery phase
was not declared for months. In the interim, OSHA inspectors were on site and
advising the clean-up contractors of safety shortcomings, without issuing formal
citations. An average of 43 violations were observed per day initially, decreasing
gradually to 33 per day by late October. OSHA, labor unions and other groups made
respirators, helmets and other equipment available and encouraged its use. The most
common problems included absent or inadequate personal protective equipment,
improper storage or use of gas cylinders (for cutting torches), and failure to mark off
zones subject to falling objects. The most common injuries resulted from inhalation
of smoke and dust, cuts and burns.4 In the first two months there were reported 40
near-miss incidents that could have been fatal.
In view of these dangers, there has been some criticism that OSHA and other
agencies did not act more vigorously at an early stage.5 In any case, on November

20, 2001 a partnership agreement was reached among OSHA, the city government,

contractors and unions. Safety hazards at Ground Zero were to be abated
immediately; data would be shared on air contaminants and other health-related
exposures; and union groups would provide training (with workers getting paid
during training time). On January 25, 2002 OSHA launched an additional “local
emphasis” enforcement program to oversee clean-up activities in a wider area
surrounding the site proper.

Long-term Health Hazards
A concern frequently expressed at the WTC, by nearby residents as well as
workers, is the long-term health hazard of dust and gaseous emissions from the site.
Unnatural odors were readily apparent, and many reported respiratory problems like
coughing and runny eyes and noses. OSHA, the National Institute for Occupational
Health and Safety (NIOSH) and health agencies continuously monitored the outside
air and reported, generally, that the levels of asbestos, benzene, PCBs, etc. did not
constitute a long-term risk to on-site workers.6 At the same time, acute respiratory
effects were evident among some workers and nearby residents.7 Preliminary
medical examination of firefighters indicated that one out of four had early signs of
asthma.8 Respiratory protection for on-site workers was clearly called for, although
not universally implemented.
One of the most critical OSHA standards potentially applicable here is the one
dealing with asbestos. In most building demolitions, hazardous materials like
asbestos are supposed to be removed before the razing begins. The WTC situation
obviously differs from a typical demolition, and many questions arise about how one
would comply with the standard. Nevertheless, it appears that regulation 29 C.F.R.
Section 1926.1101, the OSHA construction standard, does apply not only to the site
itself, but also to surrounding areas in need of repair or just clean-up. Asbestos-
containing insulation was used to coat the structural steel in the first 40 stories of the
north tower (after which a mineral wool product was used.)9 Tests of dust in and
around the WTC site have generally – but not without exception – shown asbestos
content below 1%. That would be the quantitative trigger for application of the most
stringent requirements under the OSHA regulation, but the overall standard applies
in any demolition job “where asbestos is present”. The standard establishes
quantitative exposure limits10 and a number of specific practices to be followed.
These practices include wetting down the material, using vacuum cleaners with high-

efficiency filters, enclosure and ventilation of work areas, provision of respirators,
protective clothing and personal decontamination, training and medical surveillance.
A key component of proper work with asbestos involves the use of respirators.
The OSHA standard requires their use in all Class I work and specifies the types to
be used according to the potential airborne concentrations. In no case are simple
dust-type masks adequate, since asbestos fibers are so very fine. The asbestos
standard also references OSHA’s general industry respirator standard (29 C.F.R.

1910.134), which requires medical evaluations (before the work begins), fit testing,

training, and equipment maintenance. Respirators are also called for where first
responders may encounter biological agents. (See section on anthrax, infra.)
The potential presence of other toxic materials may also implicate
environmental laws and regulations. These are discussed below in the section on
chemical plants.
Legislative Response
In recognition of these hazards in disaster areas, a bill – S. 1621 (Clinton et al.)
– has been considered and reported by the Senate Committee on Environment and
Public Works (S.Rept. 107-114). It would authorize, but not require, the President
(through the Federal Emergency Management Agency) to implement programs in
disaster areas for “protection, assessment, monitoring, and study of the health and
safety of community members, volunteers, and workers.” It authorizes a range of
possible activities such as collecting and publicizing information, training workers
and volunteers, and studying long-term health impacts.
Another measure – H.R. 4687 (Boehlert et al.) / S. 2496 (Clinton et al.) – would
provide for prompt investigation of “building failures” for making recommendations
to improve building safety standards and emergency response procedures. (H.R.

4687, as amended by the Science Committee, was passed by the House on July 12,


General Employer Responsibilities
Not only safety measures, but also general personnel policies, have come to be
considered a basic part of business planning in an era of terrorism. Some
preparations are legally binding, some are merely prudent, but in general all are
thought to be of some value in preparing for “normal” emergencies. Corporate
interest in these issues is evidenced, for example, by the emergence of a new
executive position, the Chief Security Officer.11

11 Lohr, Steve. In New Era, Corporate Security Looks Beyond Guns and Badges. New York
Times, 27 May 2002. p. C1,C3.

Building Management
Many aspects of building design and management will be governed by local
building codes, which in turn are commonly derived from private standard-writing
organizations such as the National Fire Protection Association. OSHA has added
further requirements related to fire safety (29 C.F.R. Part 1910, Subparts 155 to 165),
exit routes (Subparts 35 to 38), and first aid (Subpart 151). Recently the Department
of Health and Human Services issued advice on protecting building ventilation and
other systems in an age of terrorist threats.12 Many safety planning requirements may
seem to be no more than common sense, but unfortunately they are often violated,
sometimes with catastrophic results. A fire in 1991 in a North Carolina food
processing plant left 25 dead and 54 injured because of inoperable exit doors. On the
other end of the spectrum, some businesses are going well beyond legal requirements
with such measures as installing shatterproof glass in windows or coordinating
evacuation plans with neighboring buildings.13
Reviewing such regulations and guidelines will suggest many questions that
need to be considered and may not be so obvious at first. For example, if portable
fire extinguishers are installed, how shall they be used? Training will be required,
but who should receive it? Perhaps only certain employees should be designated to
use the extinguishers and receive the training. In which cases should employees
attempt to fight a fire – and when should they simply escape? It may be decided that
all firefighting be left to the professionals, in which case extinguishers will not be
installed (except where required by local ordinance). As to rescue activities, OSHA
can cite employers who direct employees to perform rescues without appropriate
training and equipment. (29 C.F.R. 1903.14(f))
Workers Compensation
Under state workers compensation laws (federal laws in the case of federal
employees), employers are responsible for covering medical costs and a portion of
lost earnings when injury to an employee arises “out of employment” and “in the
course of employment.” Employers and insurers at the WTC are honoring claims
connected with the September 11 attacks without contesting the applicability of these
potentially restrictive terms to the incident, with workers compensation payments
estimated to total $3.5 to $4 billion, or more than $1 million per fatality.14 Still, in
such cases insurers could have tenable grounds to contest some of these claims. It
could be argued that injury by way of terrorism was not a risk peculiarly related to
the employment of the people in the buildings, and this could place the injuries
outside the concept of arising “out of employment” as interpreted in some states. In
other states, the doctrine of positional risk applies, under which there is liability

whenever a job requires the employee to be at the time and place where an accident
occurs. More clearly, liability under workers compensation does extend to business
trips undertaken by employees to places where the possibility of terrorism, kidnaping,
or ordinary street crime is foreseeable.15
Mental problems stemming from incidents at work may also bring eligibility for
compensation. Cases of post-traumatic stress disorder among those who escaped
from the WTC, rescuers, or even those who merely witnessed the events may be
accepted much more readily than mental claims in “normal” times.16
The attacks have prompted a reassessment by insurers, who had often not
explicitly addressed the risk of terrorism previously. They are raising their premium
rates, especially where large numbers of employees are present at one location, e.g.,
high rise office buildings. Under state laws, insurers are not allowed to categorically
exclude losses caused by terrorism (although, as noted, in some states and situations,
incidents might fall outside the bounds of general principles such as “arising out of
employment”). But while employers and their insurers must bear the risk of
terrorism, the insurers’ own back-up partners (“reinsurers”) are not as tightly
regulated and have been excluding terrorism coverage. Thus some primary insurers
are finding themselves exposed to a potentially serious risk.17
Families of police and firefighters are eligible for a special payment from the
federal government if they are killed or totally disabled in the line of duty. The
“USA Patriot Act” of 2001 (Section 613 of P.L. 107-56, H.R. 3162) increased this
benefit from $150 thousand to $250 thousand. The program is administered by the
Bureau of Justice Assistance in the Department of Justice.
A novel workers compensation issue that has arisen with the appearance of
anthrax involves payment for testing and precautionary (prophylactic) treatment.
Generally, workers compensation will pay for treatment for a work-related injury or
disease if it is known to have happened, but in the case of bioterrorism this may not
be known until testing is done. So, at least in the program covering federal workers,
the situation is that workers compensation will cover the cost of testing and treatment
retroactively if and only if the test is positive. If the test is negative, costs will be
borne either by the employee, by his or her health insurer, or, at its discretion, by the
employing agency.18

Personnel Management Issues
Violence. Some of the measures that can be taken to protect against terrorism
are similar to those to prevent “workplace violence,” a term that can refer to threats
or actions coming from employees, employees’ acquaintances, clients, customers or
the general public. For most businesses, there are no regulations requiring protection
against violence, but many take the threat seriously and private consultants are active
in the field. Common measures include background investigation of employees,
controlled access to facilities and information, security guards, site surveillance, and
detailed planning to respond to threats and incidents. In applying these to terrorism19
planning, probably the most important will be access control. Depending on the
type of operation and the results of a threat and vulnerability assessment, managers
might choose to adopt one or more of the following: a limited number of entrances
(perhaps only one), staffing of entrances by trained security personnel who perform
bag searches, deliveries being accepted only at designated receiving places, and
admittance of visitors by pre-arrangement on an access list and with escort by a host
throughout their visit. However, security will have to be balanced against the need
for access, especially where access is the very raison d’etre of the facility, e.g., retail
stores and many government offices.
Discrimination and Privacy. While employers may tighten their screening
of new employees – trying, as sometimes is said, to “not hire your problems” – there
are limitations on what can be done legally. Categorically not hiring people of
particular religious or national origin groups, for example, could constitute unlawful
discrimination. Doing various background checks on individuals may require
explicit authorization from the applicant. Some factors, including criminal records,
may not be considered in hiring decisions under some state laws. On the other hand,
in certain critical occupations, such as hazmat transportation, criminal background20
checks are now required. One might also question whether there is much predictive
value in criminal records where terrorism is concerned, as opposed to traditional
problems such as pilferage. Indeed, it appears that some firms could be overreacting,
barring anyone from any position who may have committed minor offenses at any21
In a climate of fear engendered by terrorism, general suspicion may settle on
certain ethnic groups. Employers should be aware that if harassment occurs on the
job, they may bear legal responsibility. On November 19, 2001 the Equal
Employment Opportunity Commission and the Departments of Justice and Labor
issued a joint statement pledging to vigorously pursue cases of employment
discrimination or harassment on the basis of national origin or religious affiliation,
practice or manner of dress.

Street Journal, March 12, 2002. p. A1,A2.

Employee privacy also presents legal limitations, although employers can
preserve broad rights to monitor activities and conduct searches if they clearly inform
employees of their policy.22
High Profile Industries and Activities
The airline industry has been a high priority for congressional attention since the
terrorist attacks, with the most prominent safety-related bill being the Aviation and
Transportation Security Act, P.L. 107-71 (H.R. 3150/S. 1447). There are CRS
written products dealing specifically with aviation security.23 We do not deal further
with the issue here, except to note that control of unruly passengers – and the safety
of flight attendants more generally – is a related issue that has been under
consideration for many years, and is only now being broadly addressed. In
accordance with the new law, the Department of Transportation (DOT) on January

18, 2002 issued guidance to airlines for training flight crews. The guidance,

according to DOT, “represents a shift in strategy from passive to active resistance by
crew members,” and the training will include live, situational exercises.24
Chemical and Nuclear Hazards
There are many programs in place to prevent, mitigate and respond to the
accidents that can occur when producing, processing, storing or shipping toxic or
radioactive materials. These have primarily been predicated on unintentional
scenarios, but industrial and utility facilities may well become a target of terrorists
because of the potential for wide dispersion of toxic materials and/or disruption of
vital infrastructure. Consequences could be disastrous. A review of risk
management plans required by the Clean Air Act (see infra) showed that, for more
than half of the reporting facilities, more than 1000 people live within the affected
range of a worst case release.25 The terrorist threat prompts renewed consideration
of whether existing programs are basically sound and adequately financed, whether
they are consistent and coordinated, whether they apply to a wide enough range of
facilities, and whether they take into account the possibilities of malicious intent.
The President addresses such issues in the “critical infrastructures” section of his

anti-terrorism “National Strategy”,26 where key priorities include collecting much
more information about vulnerabilities and coordinating the efforts of public and
private sectors.
Corporate Responsibilities and Activities. Among the major programs
promoting preparedness for industrial-related emergencies are:
!OSHA’s Process Safety Management Standard (29 CFR 1910.119);
!Risk Management Plans required under Section 112(r) of the Clean Air Act
(40 CFR, Part 68);
!OSHA’s standard on Hazardous Waste Operations and Emergency Response
(HAZWOPER) (29 CFR 1910.120);
!The National Contingency Plan under the Superfund Act (40 CFR, Part 300);
!State and local activities authorized by the Emergency Planning and
Community Right-to-Know Act (42 U.S.C. 11001-11050); and
!Diverse programs administered by the Federal Emergency Management
Agency. 27
Covered industrial facilities are required to develop plans including elements
such as: hazard assessment, mitigation strategies, maintenance and testing of
equipment, training and exercises, alarms and communication systems, and command
structures (including coordination with public authorities). Generally speaking, the
first three of the above regulations are directed at operators of industrial facilities
handling significant quantities of materials that are toxic, explosive, flammable,
corrosive or otherwise hazardous to human populations or the environment. The
latter three are designed to encourage planning and coordination with public
authorities in localities that may be affected. There are public-private overlaps in all
of these, however. One of the challenges presented by industrial disasters is that they
call for planning and response by so many parties and agencies. An interagency
group, led by the Environmental Protection Agency (EPA), has tried to simplify the
process for plant operators by issuing a model plan that can be used to comply with28
many of the laws at once. More broadly, the President’s National Strategy
document indicates an intention to consolidate the various government disaster
response plans into a unified “Federal Incident Management Plan.”
The private sector has also made efforts to tighten security on its own initiative.
For example, the chemical industry trade associations have issued guidelines for site29
security. Points covered include: assessment of threats and vulnerabilities, hiring
and termination practices, perimeter protection, testing and maintenance, backup
systems, information security, and collaboration with law enforcement and other

community agencies.30 While the member companies of these associations are
committed to using the guidelines, they are not legally obligated to do so. And while
the members include the largest firms and account for most of the industry’s facilities
and capacity, there are numerous facilities of substantial size at other firms that do
not participate.
Concern about remaining vulnerabilities prompted the Congress in 1999 (P.L.
106-40) to call for a special study by the Department of Justice of possible terrorist
dangers.31 Since the September 2001 terrorist attacks, S. 1602 (Corzine et al.) has
been introduced to require plant operators to consider explicitly the risks of terrorist
or criminal action (including theft of hazardous materials), and modify their
operations so as to reduce the probability and potential consequences of releases.
The unique dangers associated with certain other industries led to much more
rigorous and specialized regulatory regimes for them many years ago, most notably
those for nuclear energy and hazardous materials (hazmat) transport. These are
explained in other CRS reports.32
Emergency Management Systems. Starting around 1950, federal disaster
planning went on two tracks: for natural disasters and for possible nuclear attack
(“civil defense”). Over time, concern about nuclear war decreased while a perception
grew that there was significant overlap in the requirements for these two types of
preparedness. In practice, resources originally developed for civil defense were
redirected toward natural disasters.33 The priority pendulum may now have swung
back toward a military orientation but, in any case, the “dual use” concept appears
still to be valid.
There is at least one issue in industrial disaster preparedness – public disclosure
of information – that highlights a significant difference between civilian and military
issues. The risk management plans under the Clean Air Act include lists of toxic
chemicals and analyses of “worst case scenarios” of possible releases into
surrounding communities. Since at least 1993, when the regulations were under
consideration, the concern has been raised that public dissemination of such
information could enable would-be terrorists to plan the most damaging possible34
attacks. Amendatory legislation (P.L. 106-40) was passed in 1999 to put limits on

(Awareness of National Security Issues and Response), whereby the FBI notifies corporate
security directors of possible threats, including industrial espionage. See

the terrorist attacks of September 2001, the EPA and the Nuclear Regulatory

of such information.
There is a difficult balancing here, as disclosure of information could, on the
one hand, increase the risks of terrorist actions while, on the other, lead to reduction
in the risks of accidental releases (or at least improve the public’s ability to plan for
emergencies in their communities). Another problematic aspect of information flow
is that owners of critical infrastructure may be reluctant to disclose possible
vulnerabilities to the government from concern over legal liability or investor
reaction. S. 1456 (Bennett, Kyl et al.) would provide a greater degree of
confidentiality for critical information voluntarily shared with the government.
Anthrax and Mail Handling35
Mail Operations in General. OSHA and the Centers for Disease Control
(CDC) have issued guidance for dealing with potential anthrax and other bioterror
agents in workplaces. To date, the experience has been that mail handling areas,
whether public or private, have presented the greatest risk. With regard to anthrax,
OSHA categorizes workplaces into three levels of risk. The vast majority of
workplaces are in the “green zone,” i.e., where contamination is unlikely. The
recommendations consist mainly of general hygienic-type precautions, actions that
will minimize skin contact with the mail and are least likely to spread any contents
in the air. Nitrile or vinyl gloves are optional; respirators are not recommended in
the green zone.
In the “yellow zone” – which includes facilities handling bulk mail and/or mail
coming from contaminated places – engineering controls are the preferred strategy,
although these may take considerable time to implement. These are aimed essentially
at exhaust ventilation of air from around mail handling machinery and thorough
filtering of circulating air. After engineering controls, prudent work practices are
called for, such as using wet cleaning methods and properly filtered vacuums.
Finally, impermeable gloves are called for. Properly chosen and fitted respirators
should be used by those working around machinery that could generate aerosolized36
particles, e.g., automatic sorters.
Finally, the “red zone” applies to facilities where contamination is confirmed
or strongly suspected. Only qualified emergency response personnel should be
involved, with the operative requirements being those of OSHA’s HAZWOPER

OSHA’s guidance would not apply them to places such as small business mail rooms.

standard. Depending on the situation, this may include the highest degree of
respiratory and skin protection.
U.S. Postal Service. The Postal Service (USPS) has taken a number of steps
to ensure the safety of its workers as well as the general public. These include:
testing of employees who may have been exposed, closure and cleaning of work
areas found to be contaminated, irradiation of mail, and provision of gloves and
masks. In addition, a task force of managers, labor and industry associations was
established to monitor developments and recommend solutions. While most
observers consider USPS response much improved since the confusing first days of
the crisis in October 2001, there are a number of unresolved issues. For example,
differences have arisen between the USPS and some of its unions (and among the
different union groups) over whether entire buildings must be shut down when
contamination is found, or just the immediate work area. Some also question the
safety of Cipro and other antibiotics.37
More broadly, it remains to be seen how much of the financial cost of
responding to this threat can be borne by the Postal Service. The Administration
allocated $175 million in an emergency grant, but much more will be needed for full
implementation of steps such as irradiation. Moreover, the USPS financial condition
has deteriorated due to a decline in mail volume.38 It is not clear whether private
sector express delivery companies are gaining a competitive advantage from the
situation, or whether the USPS should adopt any of their procedures in response.
While there are no absolutes, some consider the private company traffic less likely
to contain dangerous agents because senders are identified and all packages are39
tracked. Moreover, most of their shipments are sent business-to-business.
Emergency Responders. As noted, areas where biological agents are
suspected are considered a “red zone,” calling for a high level of respiratory
protection. Use of self-contained breathing apparatus (SCBA) is recommended by
groups such as the National Fire Protection Association in situations where the nature
of a hazard has not been established. In addition to the usual standards pertaining to
SCBAs, the National Institute for Occupational Safety and Health (NIOSH) has
begun a voluntary certification program whereby specific models of equipment will
be labeled as suitable for use against biological, chemical and radiological agents.40
The Department of Labor has initiated a partnership with the Laborers
International Union to develop a biohazard clean-up curriculum. It will be used first

to upgrade the skills of workers already certified for hazardous waste operations, and
later distributed to organizations such as OSHA training institutes.
Finally, scientific uncertainties remain as to the best prophylactic regimen for
workers with inhalation exposure to anthrax. It is believed that the disease is
unlikely to develop more than 60 days after exposure, hence the recommendation for
60 days of antibiotic treatment. However, there is some evidence of live spores in
lungs as much as 100 days after exposure. Therefore, the Department of Health and
Human Services advises that people may wish to consider 40 more days of antibiotic
treatment. In addition, the Department is making available vaccine on an
“investigational” basis as a post-exposure treatment.41
Bioterrorism legislation passed in the 107th Congress – P.L. 107-188 (H.R. 3448
(Tauzin et al.)/S. 1765 (Frist et al.)) – aims at a comprehensive enhancement of
national preparedness.42 Among other measures, Section 153 directs NIOSH to
expand its research on the safety of “workers who are at risk for biological threats or
attacks in the workplace.” More specifically on emergency responders, Section
131(a) establishes a state block grant program which, among other things, funds
training initiatives to improve detection and response to biological threats, including
“training and planning to protect the health and safety of personnel . . . involved in
responding to a biological attack.” Meanwhile, the President’s budget proposal for
FY2003 would expand by ten-fold, to $3.5 billion, federal support to states and
localities for homeland security capabilities of first responders. The intention is to
use this additional planning, equipment, training and exercises, to improve their
general preparedness for “everyday emergencies” as well as terrorist threats of many
