A Certified Industrial Hygienist (CIH) is a professional who specializes in identifying and controlling environmental hazards in the workplace that could affect employee health and safety. These hazards may include chemical exposure, air quality issues, noise, radiation, biological agents, and ergonomic stressors. CIHs are certified by the American Board of Industrial Hygiene (ABIH) after meeting rigorous education, experience, and examination requirements, making them one of the most trusted resources for occupational health and safety consulting.
CIHs play a vital role in creating safer work environments across a wide range of industries including manufacturing, construction, energy, healthcare, and government. They evaluate potential risks using scientific methods such as air sampling, noise measurements, and chemical exposure assessments. From there, they recommend controls like ventilation improvements, personal protective equipment (PPE), engineering solutions, or changes to workplace procedures to minimize risk.
In addition to identifying hazards, CIHs are also responsible for ensuring compliance with OSHA, NIOSH, and other regulatory standards. Their expertise is often called upon during audits, accident investigations, or when companies want to proactively assess risk before expanding operations or launching new facilities. Their input can be critical for reducing liability, lowering insurance premiums, and maintaining worker productivity.
Hiring a CIH can benefit organizations both large and small. Whether it’s improving indoor air quality, conducting mold or asbestos inspections, or setting up a respiratory protection program, a CIH provides evidence-based strategies for healthier, more compliant workplaces. They also assist in training programs, policy development, and long-term health and safety planning.
Ultimately, a Certified Industrial Hygienist is more than just a safety consultant—they’re a vital part of your risk management strategy. By identifying unseen threats and implementing preventative measures, CIHs help protect your workforce, safeguard your operations, and ensure your company remains compliant and competitive in today’s highly regulated landscape.
