General Standards/Guidelines

Standards or Threshold Limit Values (TLVs) for airborne concentrations of mold, or mold spores, have not been set. Currently, there are no EPA regulations or standards for airborne mold contaminants.

There are currently no specific OSHA Standards or Directives for molds and fungi. However, Indoor Air Quality (IAQ) hazards are addressed in specific standards for general and construction industries. This page provides links to those standards as well as references related to OSHA enforcement policy such as federal registers. In addition, this page links to standards from industry, such as the American National Standards Institute (ANSI). Note: Some states have OSHA-approved State Plans and have adopted their own standards and enforcement policies.

OSHA Federal Registers

Indoor Air Quality. OSHA Federal Register Entry 59:15968-16039 (1994, April 5). By this notice, the Occupational Safety and Health Administration (OSHA) proposes to adopt standards addressing indoor air quality in indoor work environments.

Respiratory Protection. OSHA Federal Register Entry 63:1152-1300 (1998, January 8). This final rule justifies the use of respirators to prevent the inhalation of harmful airborne contaminants that are alive or were released from a living organism. Respirators protect against bacterial infections resulting from inhalation of bacteria and their products that cause a range of diseases.

Standard 62-2001, Ventilation for Acceptable Indoor Air Quality. American National Standards Institute/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ANSI/ASHRAE). This standard sets minimum ventilation rates and other requirements for commercial and institutional buildings.
