Industrial Hygiene & Occupational Health

This advanced Industrial Hygiene & Occupational Health course provides a comprehensive understanding of workplace health hazards, exposure assessments, and control measures based on international standards (OSHA, ACGIH, NIOSH, and ISO 45001).

The course includes hands-on training in industrial hygiene monitoring, exposure calculations, and risk assessment techniques. Key focus areas include:

✔ Airborne Contaminant & Exposure Limit Calculations (TWA, STEL, PELs, RELs, TLVs)
✔ Ventilation System Design & Performance Calculations (Dilution & Local Exhaust Ventilation – LEV)
✔ Noise Exposure & Hearing Conservation (Decibel Adjustments, Noise Dose Calculations)
✔ Heat Stress Indices & Metabolic Workload Calculations
✔ Toxicological Risk Assessments & Dose-Response Modeling
✔ Biological Exposure Indices (BEIs) & Chemical Exposure Limits

Practical workshops, real-world case studies, and exposure assessment exercises will enhance participants’ ability to apply industrial hygiene principles effectively in various industries, including oil & gas, chemical processing, manufacturing, and construction.

This course also serves as a valuable preparation resource for professionals pursuing BCSP certifications (CSP, ASP) by covering essential Industrial Hygiene topics included in the exam syllabus. Participants will develop a strong foundation in exposure assessment, workplace health risk evaluations, and control strategies, which are critical for success in the BCSP examinations.

Assessment and Certification:

Upon completion, participants receive a Certificate in Advanced Industrial Hygiene & Occupational Health, validating their skills in exposure assessment, risk analysis, and workplace health protection.
