Biological hazards originate from living organisms or their byproducts and may include bacteria, viruses, fungi, mold, parasites, and other biological agents. Exposure can occur through inhalation, ingestion, skin contact, or other routes.

Mold growth can contribute to respiratory irritation, allergic reactions, and other health effects depending on exposure conditions and individual susceptibility. Effective control measures include moisture management, ventilation, housekeeping, and prompt remediation of affected materials.

OHST professionals may participate in investigations involving indoor environmental quality and biological exposures. Recognizing biological hazards is important because they often require different control strategies than physical, chemical, or ergonomic hazards.

Occupational health programs seek to identify and manage biological hazards to protect worker health and maintain safe workplace conditions.
