New Jersey Indoor Air Quality Standard (N.J.A.C. 12:100-13)


Exposure to indoor contaminants represents one of the most wide-spread exposures affecting public employees. Contaminants generated indoors can be concentrated in indoor air by inadequate or improperly operating ventilation systems that do not provide enough dilution ventilation. Contaminants can also be introduced by construction/ renovation projects within the building or from exterior sources entering a building. Health effects caused poor indoor air quality can range from general malaise, such as fatigue and headache to more serious symptoms such as asthma and infections. Indoor air quality issues represent approximately 60% of the complaints investigated by PEOSH.

The New Jersey Indoor Air Quality standard, N.J.A.C. 12:100-13 (2007), sets standards for indoor air quality in existing buildings occupied by public employees during their regular working hours. The Indoor Air Quality Standard is one of the only state indoor air quality standards in the U.S.

Additional IAQ Resources
  • State Agencies with Major Indoor Responsibilities for Public Buildings:

    NJ Department of Health

    Environmental and Occupational Health Assessment Program
    The mission of the Program is to protect the health of the public by reducing residents and workers’ exposure to chemical, physical, and biological hazards including asbestos-containing materials, bloodborne pathogens, lead-based paint hazards, and many others. Additionally, the Program:

    • handles issues related to school construction, Brownfields redevelopment, and related activities
    • administers federal grants including U.S. EPA Tools for Schools Program
    • maintains a list of private mold consultants, laboratories, and remediation firms
    • enforces the provisions of the PEOSH Hazard Communication standard, and
    • maintains database of employer Right to Know annual surveys.
  • U.S. Environmental Protection Agency (EPA) - IAQ Publications and Programs

    The EPA has major indoor air responsibility for public and commercial buildings and offer many programs and publications:

    • Office of Radiation and Indoor Air Indoor Environments Division
      Conducts a non-regulatory indoor air quality program that emphasizes research, information dissemination, technical guidance, and training. Issues regulations and carries out other activities that affect indoor air quality under the laws for pesticides, toxic substances, and drinking water.

    • IAQ Tools for Schools (TfS) Kit
      The IAQ TfS Kit shows schools how to carry out a practical plan of action to improve indoor air problems at little or no cost using straightforward activities and in-house staff. The Kit provides best practices, industry guidelines, sample policies, and a sample IAQ management plan. The voluntary guidance can save schools and money so that resources can be directed toward educating children. The IAQ TfS Kit is co-sponsored by the National Parent Teacher Association, National Education Association, Association of School Business Officials, American Federation of Teachers, and the American Lung Association.

    • Healthy School Environments Assessment Tool
      The Healthy School Environments Assessment Tool (SEAT) is a free software tool to help school systems manage more effectively their environmental issues. HealthySEAT is designed to be customized by school systems to conduct and manage self-assessments of their school facilities for a wide range of environmental, health, and safety issues.
