CDC Invites Public Comment on Extension of Critical Workplace Health Hazard Evaluation Program
On June 18, 2026, the Centers for Disease Control and Prevention (CDC) published a Federal Register notice inviting public comment on the proposed extension of a vital data collection program. This initiative, known as Health Hazard Evaluations (HHE), is administered by the National Institute for Occupational Safety and Health (NIOSH) and serves as a primary federal mechanism for identifying and addressing chemical, biological, and physical hazards in workplaces across the United States. The call for public input, open until August 17, 2026, underscores the program's ongoing importance to worker safety and public health, while also fulfilling regulatory requirements under the Paperwork Reduction Act of 1995.
The Mandate Behind Workplace Safety
The HHE program operates under the clear directives of the Occupational Safety and Health Act of 1970 and the Federal Mine Safety and Health Act of 1977. These foundational pieces of legislation empower NIOSH to respond to requests from employees, employers, and authorized representatives seeking to investigate potential health hazards in their work environments. The core mission of an HHE is to identify the nature and extent of workplace hazards and to provide recommendations for their elimination or control. This proactive approach to occupational health is a cornerstone of federal efforts to ensure safe working conditions across diverse industries.
Anatomy of a Health Hazard Evaluation
NIOSH's process for conducting Health Hazard Evaluations is multi-faceted, beginning with the initial request. The agency receives approximately 250 requests annually, originating from a variety of sectors, including services, manufacturing, health and social services, transportation, and construction. To facilitate these requests, NIOSH provides forms in multiple languages, both in printed format and online, enhancing accessibility for a broad spectrum of the workforce. These forms are designed to gather the necessary preliminary information as required by federal regulations, taking an estimated 12 minutes to complete.
Upon reviewing a request, NIOSH determines whether an on-site evaluation is warranted, which occurs for approximately 25 percent of all requests. During these on-site visits, NIOSH specialists conduct thorough assessments. Employee interviews are a common component, occurring in about 70 percent of on-site evaluations. These informal discussions, lasting around 15 minutes per respondent, help to further define specific concerns related to suspected diseases and hazards, using standard medical practices as a guide.
A smaller fraction of on-site evaluations, less than one percent, may involve medical tests or the collection of biological samples. In such instances, informed consent is meticulously obtained, a process estimated to take 30 minutes per participant. This ensures individuals fully understand the purpose, potential risks, and benefits of participation, with the option to decline. Additionally, approximately 30 percent of on-site evaluations include the distribution of questionnaires to employees. These surveys, which may take about 30 minutes to complete for an average of 100 employees per site, use standardized or widely accepted medical and epidemiologic data collection instruments to gather specific information pertinent to the workplace's unique conditions.
Employee exposure monitoring is another critical aspect, occurring in about 70 percent of on-site evaluations. For employees wearing samplers or monitoring devices, the opportunity to receive personal exposure results is offered. Completing a contact information postcard for this notification takes five minutes or less. Following these evaluations, NIOSH disseminates interim and final reports, devoid of personal identifiers, to relevant parties including requesters, employers, employee representatives, and government agencies.
Assessing Program Effectiveness and Public Participation
To gauge the impact of its HHE program, NIOSH administers a comprehensive follow-back program. This involves sending multiple questionnaires to employer and employee representatives at workplaces that received an on-site evaluation. A first questionnaire is sent shortly after the initial visit, a second after the final report, and a third at the 12-month mark, taking 10, 20, and 15 minutes respectively. For requests not resulting in an on-site evaluation, two follow-back questionnaires are sent. These follow-ups are crucial for assessing the effectiveness of hazard reduction strategies implemented following NIOSH's recommendations.
Under the Paperwork Reduction Act of 1995, federal agencies must seek approval from the Office of Management and Budget (OMB) for information collections. The current notice serves as the required 60-day public comment period for the proposed extension of the HHE data collection, identified as OMB Control No. 0920-0260. The CDC/NIOSH is requesting a three-year approval for this consolidated clearance, citing the necessity to respond quickly to a high volume of diverse and unpredictable investigations. The estimated total annual burden hours for respondents across all activities is 1,745 hours, with no direct cost to respondents other than their time.
The agency is specifically interested in comments that address the utility and necessity of the proposed information collection, the accuracy of its burden estimates, ways to enhance data quality and clarity, and methods to minimize the burden on respondents through technological advancements. This open invitation for feedback ensures that the program remains efficient, effective, and minimally burdensome while continuing to serve its vital public health function.
Implications for Worker Health and Safety
The ongoing commitment to the HHE program signifies a continuous federal effort to protect the American workforce. By extending this data collection, NIOSH ensures it can continue to identify emerging hazards, respond to specific workplace concerns, and provide evidence-based recommendations that lead to healthier and safer work environments. The data gathered through HHEs not only informs immediate hazard mitigation but also contributes to a broader understanding of occupational health trends and the development of preventive strategies. This program is a testament to the federal government's role in public health surveillance and intervention, directly impacting the well-being of millions of workers.
