NIOSH

5th Edition Web Book

The National Institute for Occupational Safety and Health (NIOSH) is the U.S. federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness. NIOSH is part of the Centers for Disease Control and Prevention (CDC) in the U.S. Department of Health and Human Services. The NIOSH Manual of Analytical Methods (NMAM) is a compilation of validated sampling and analytical methods that are used globally for occupational exposure assessment in the industrial (occupational) hygiene field and related professions. The methods that are published in NMAM are evaluated and validated in consideration of their fitness-for-purpose for exposure monitoring in work areas. NIOSH methods primarily address workplace air sampling and analysis, but NMAM also includes protocols for biological, surface, dermal, and bulk samples. Within NMAM, but separate from the methods themselves, are assorted chapters providing background and guidance covering a number of subjects. Explanatory chapters on quality assurance, sampling guidance, method development and evaluation, aerosol collection, etc., provide valuable information to users of NIOSH methods. NMAM chapters provide a convenient resource that augments technical information often (but not always) available elsewhere in texts and monographs. Now in its fifth edition, NMAM is continuously updated as new or revised methods are evaluated and their performance verified.

This document is a compilation of its guidance chapters and methods, current as of the date shown on the front page. NMAM is published online on the NIOSH web page and is available worldwide free of charge. Users are encouraged to visit the NMAM 5^th edition website for the most current methods and guidance chapters.
