Occupational Exposure to Tuberculosis

AGENCY: Occupational Safety and Health Administration (OSHA), Labor. ACTION: Proposed rule; termination of rulemaking.

SUMMARY: OSHA is withdrawing its 1997 proposed standard on Occupational Exposure to Tuberculosis (TB). Because of a broad range of Federal and community initiatives, the rate of TB has declined steadily and dramatically since OSHA began work on the proposal in 1993. Hospitals, which are the settings where workers are likely to have the highest risk of exposure to TB bacteria, have come into substantial compliance with Federal guidelines for preventing the transmission of TB. Overall reductions in TB mean that all workers are much less likely now to encounter infectious TB patients in the course of their jobs.

In addition, an OSHA standard is unlikely to result in a meaningful reduction of disease transmission caused by contact with the most significant remaining source of occupational risk: exposure to individuals with undiagnosed and unsuspected TB. Particularly outside of hospitals, workers often will not identify suspect TB cases quickly enough to implement isolation procedures and other precautions before exposure occurs.

OSHA recognizes, however, that continued vigilance is necessary to maintain the gains achieved so far. OSHA intends to provide guidance to workplaces with less medical expertise and fewer resources than hospitals, and to use cooperative relationships with employers, public health experts and other government agencies to promote TB control. OSHA will also continue to enforce the General Duty Clause of the OSH Act and relevant existing standards in situations where employers' failure to implement available precautions exposes workers to the hazard of TB infection.

DATES: This withdrawal is effective December 31, 2003.


On August 25, 1993, the Coalition to Fight TB in the Workplace petitioned OSHA to promulgate both an Emergency Temporary Standard (ETS) under section 6(c) of the Occupational Safety and Health Act (OSH Act), and a permanent occupational health standard under section 6(b) of the Act to protect workers from occupational exposure to TB (Ex.1). 29 U.S.C. 655(b), 655(c). Citing the resurgence of TB at that time and the emergence and increasing prevalence of multi-drug resistant TB (MDR-TB), the petition argued that a mandatory standard was needed to address the hazards associated with occupational exposure to TB. According to the petition, TB Guidelines developed by the Federal Centers for Disease Control and Prevention (CDC) were not an adequate response to this hazard because the guidelines were not mandatory and were not being implemented fully or rigorously in most workplaces. The petition also requested that, as an interim measure, OSHA immediately issue nationwide enforcement guidelines.

On January 26, 1994, OSHA responded to the rulemaking petition, saying that it was initiating rulemaking on a permanent standard, but would not issue an ETS. On October 17,1997, OSHA published a Proposed Rule on Occupational Exposure to Tuberculosis (62 FR 54160). In the proposal, the Agency made a preliminary determination that workers in hospitals, nursing homes, hospices, correctional facilities, homeless shelters, and certain other work settings faced a significant risk of incurring TB infection through occupational exposure. The Agency also made a preliminary conclusion that use of established infection prevention and control measures could reduce or eliminate this significant risk. The protective measures OSHA proposed were based in large part on existing CDC guidelines, and included instituting procedures for the early identification and treatment of TB patients, isolating patients with infectious TB in rooms designed to protect others from contact with disease-causing microorganisms, requiring healthcare workers to use respirators to perform certain high-hazard procedures on infectious patients, training workers in TB recognition and control, and providing medical follow-up foroccupationally exposed workers who become infected and information to their colleagues with similar exposures.

II. Reasons for Withdrawal ofthe Proposed Standard

OSHA has decided not to promulgate a standard addressing occupational exposure to TB because it does not believe a standard would substantially reduce the occupational risk of TB infection. Many commenters argued forcefully that the proposed rule was based on an overestimate of this risk. In addition, existing TB control efforts, initiated by the Federal government in concert with other public health agencies, have led to a dramatic decline in TB over the past decade, greatly reducing the risk of occupational exposure to TB. Because of these TB control efforts, effective infection control measures are already in place, particularly in hospitals, which is where the occupational risk of TB exposure would be most severe.

In summary, OSHA has concluded that the success of existing Federal and community programs to control TB has significantly diminished the need for a standard, and that promulgating a standard will not reduce the remaining occupational risk substantially. Under the leadership ofthe CDC, community, institutional, and occupational public health efforts, including OSHA's own continuing outreach and enforcement, have increased worker and employer awareness ofthe factors leading to TB infection and disease and led to an increased implementation of CDC's TB guidelines. OSHA also intends to continue to use its enforcement, outreach, and education resources to ensure that employers' TB control efforts remain effective.
