Accredited Industrial Hygiene Laboratories

Quick Tips #159

The Industrial Hygiene Laboratory Accreditation Program (IHLAP) is designed for labs that analyze samples taken in the work environment. The laboratory accreditation program will help ensure you are meeting the stringent quality control standards on which your important safety and health decisions are based.  

Criteria for laboratory accreditation include personnel qualifications for education and work experience for the laboratory director, laboratory supervisor and quality control coordinator. Laboratories must meet adequate facility and equipment guidelines, periodic reviews of their laboratory records and methods of analysis and quality control procedures. Site visits are conducted approximately every three years by experienced inspectors sent by the AIHA. The accreditation period is for a length of three years.
