3. Advocacy and Public Policy Influence

AIHA acts as an intermediary between science and public policy. The organization’s government affairs team acts at the federal, state, and local levels to influence regulations and funding agendas. Chief among advocacy activities are: 

  • Regulatory Commenting: Providing technical comments on planned Occupational Safety and Health Administration (OSHA) regulations, like permissible exposure levels (PELs) for chemical agents, and participating in OSHA stakeholder meetings. 
  • Coalition Development: Collaborating with like-minded organizations such as the National Institute for Occupational Safety and Health (NIOSH), the National Safety Council (NSC), and labor unions to promote shared objectives. 
  • Funding Research Agendas: Encouraging Congress and federal agencies to fund occupational health research, particularly in innovative areas such as heat stress, indoor air quality, and mental health. 
  • Public Awareness Campaigns: Encouraging National Industrial Hygiene and Safety Month every April to highlight workplace health issues by way of webinars, social media toolkits, and press releases. 

By doing so, AIHA assists in ensuring that regulations are based on careful science and that worker health becomes a legislative priority. 

 

4. Knowledge Dissemination: Publications and Research

AIHA’s portfolio of peer-reviewed journals, white papers, and fact sheets benefits both practitioners and researchers: 

  • Journal of Occupational and Environmental Hygiene (JOEH): Publishes original research, reviews, and case reports on exposure science and industrial hygiene practice. 
  • AIHA Periodicals and E-Newsletters: Periodically published bulletins report on new method advancements, regulations, and member successes. 
  • Technical White Papers: Detailed examinations of individual challenges—for instance, best practices on lead exposure in battery recycling or evaluation of COVID-19 aerosol transmission controls. 
  • Best Practices Toolkits: Detailed instructions, like the Comprehensive Noise Control Program toolkit, offer practical guides for employers. 

These documents act as a key repository of knowledge, encouraging innovation and promoting consistency among the industrial hygiene field. 

 

5. Education, Outreach, and Community Engagement

AIHA broadens its scope beyond credentialed experts by interacting with the general public and industrial community: 

  • Workshops and Short Courses: Hands-on training on subjects including entry to confined spaces, selection of respiratory protection, and chemical risk communication. 
  • Webinars and Virtual Town Halls: Convenient online events with expert panels, case study presentations, and live Q&A sessions. 
  • Student Chapters and University Partnerships: Working with university programs in industrial hygiene, occupational health, and engineering to mentor students and incorporate real-world projects into course work. 
  • Scholarships and Grants: Assistance for graduate research studies, travel grants to cover expenses for attending AIHA conferences, and awards for outstanding service to the profession.
