Frequently Asked Questions
What is the difference between a CIH and a general safety consultant?
A Certified Industrial Hygienist (CIH) holds a specific credential issued by the American Board of Industrial Hygiene that requires a qualifying degree in science or engineering, documented professional experience in industrial hygiene practice, and passage of a comprehensive written examination. The CIH credential is the recognized benchmark of competence in occupational health assessment. A general safety consultant may hold other credentials (such as CSP) but does not necessarily have the scientific depth in exposure assessment, toxicology, and industrial health that a CIH brings to complex occupational health problems.
What industries does DocAir serve in Nashville?
DocAir provides CIH services to manufacturing and process industries, healthcare and laboratory settings, commercial construction and renovation, office and institutional occupancies, and distribution and warehousing facilities throughout the Nashville, Franklin, Brentwood, and Middle Tennessee area. No two industrial hygiene engagements are identical, our approach is calibrated to the specific hazards and regulatory obligations relevant to your operation.
Does DocAir offer both testing and remediation?
Yes. DocAir's integrated service model means that the team that identifies a problem, whether it is poor air quality, mold growth, vapor intrusion, or moisture infiltration, can also manage the remediation.
