Course Description
The Certified Industrial Hygiene Technician (CIHT) course is a comprehensive professional training program designed to equip participants with the knowledge and practical skills needed to recognize, evaluate, and control occupational health hazards in a wide range of workplace environments. This course prepares safety professionals, technicians, supervisors, and occupational health personnel to identify workplace exposures, implement effective hazard controls, and support compliance with OSHA regulations and industrial hygiene best practices.Industrial hygiene plays a critical role in protecting employees from workplace hazards that may cause illness, injury, or long-term health effects. Throughout this course, participants will gain a solid understanding of occupational exposure assessment, industrial hygiene monitoring, air sampling techniques, noise monitoring, ventilation systems, personal protective equipment (PPE), and strategies for controlling chemical, biological, physical, and ergonomic hazards.
Students will learn how to identify workplace hazards, perform basic industrial hygiene evaluations, interpret exposure monitoring data, and recommend practical engineering, administrative, and personal protective controls. The course also introduces participants to hazard communication, respiratory protection, confined space awareness, occupational health principles, and workplace exposure prevention methods used across manufacturing, construction, healthcare, laboratories, oil and gas, utilities, mining, and other industrial sectors.
Practical instruction focuses on recognizing airborne contaminants, hazardous chemicals, dust, vapors, gases, fumes, noise, heat stress, cold stress, biological hazards, and other occupational health risks. Participants will also explore exposure assessment methodologies, sampling equipment, workplace inspections, documentation practices, and regulatory compliance requirements that support effective occupational health and safety programs.
Upon successful completion of the Certified Industrial Hygiene Technician (CIHT) course, participants will have the confidence to support industrial hygiene programs, assist with workplace exposure assessments, improve employee health protection, and contribute to safer working environments. This certification is ideal for professionals seeking to build a career in occupational health, industrial hygiene, environmental health and safety (EHS), and workplace compliance.
