NIOSH Pocket Guide to Chemical Hazards
The NIOSH Pocket Guide to Chemical Hazards (NPG) informs workers, employers, and occupational health professionals about workplace chemicals and their hazards. The NPG gives general industrial hygiene information for hundreds of chemicals/classes. The NPG clearly presents key data for chemicals or substance groupings (such as cyanides, fluorides, manganese compounds) that are found in workplaces. The guide offers key facts, but does not give all relevant data. The NPG helps users recognize and control workplace chemical hazards.
NIOSH offers four versions of the NPG: print, online, PDF, and mobile web app.
For chemicals not listed and/or lacking occupational exposure limits (OELs), NIOSH recommends consulting the NIOSH Occupational Exposure Banding Safety and Health Topic Page.
