How to Become a Certified Industrial Hygienist (CIH)?


How to Become a Certified Industrial Hygienist : Becoming a Certified Industrial Hygienist (CIH) is a prestigious and rewarding career path for professionals dedicated to ensuring health and safety in workplaces. The CIH certification demonstrates your expertise in industrial hygiene practices and can open doors to diverse job opportunities in various industries. In this article, we will guide you through the steps to become a CIH.

Step 1: Educational Foundation

To begin your journey toward becoming a CIH, you should establish a strong educational foundation. Most candidates hold at least a bachelor’s degree in a related field, such as industrial hygiene, environmental health, chemistry, or a similar discipline. Some may opt for master’s degrees for advanced knowledge and career prospects.

Step 2: Gain Relevant Work Experience

To qualify for the CIH certification, you need to accumulate practical experience in the field of industrial hygiene. The American Board of Industrial Hygiene (ABIH), the organization that grants CIH certification, typically requires candidates to have a minimum of four years of professional-level experience in industrial hygiene or a related field. This experience is crucial for developing the necessary skills and knowledge to excel as a CIH.

Step 3: Prepare for the CIH Exam

The next significant step is to prepare for the CIH examination, which is known for its rigor and comprehensiveness. The ABIH exam covers various aspects of industrial hygiene, including exposure assessment, hazard controls, air sampling, and regulatory compliance. To succeed in the exam, you should engage in thorough preparation, including studying the exam outline provided by the ABIH, using recommended study materials, and taking practice tests.

Step 4: Apply for Certification

Once you believe you meet the educational and experience requirements and are well-prepared for the exam, you can apply to take the CIH exam through the ABIH’s website. Ensure that your application is complete and that you pay the necessary application and examination fees.

Step 5: Take and Pass the CIH Exam

Upon approval of your application, you will receive instructions on scheduling your CIH exam. The CIH exam is typically computer-based and consists of multiple-choice questions, as well as a written assessment component. It’s essential to arrive at the exam well-prepared and confident. Passing the CIH exam is a significant milestone on your path to becoming a Certified Industrial Hygienist.

Step 6: Maintain Your Certification

Once you’ve achieved CIH certification, it’s crucial to maintain it by fulfilling recertification requirements. The ABIH requires CIHs to recertify every five years, which involves accumulating certification maintenance points (CMPs) through ongoing professional development activities, such as continuing education, research, and practice. Staying up-to-date with industry best practices and regulations is vital for a successful career as a CIH.
