About the Database
This database contains chemical exposure readings from OSHA inspections dating from 1984 through 2013. These data may be searched by year, by state, by establishment type and by substances detected. Individual inspection data may also be viewed.
The objective of this project is to develop a geo-spatial website to communicate OSHA personal monitoring sampling data.
The audience for this is primarily workers concerned about their potential exposures in any place they have worked, in any timeframe. A worker may obtain a time weighted yearly exposure, short-term exposure, and cumulative exposure for each monitored substance.
If you want to jump right in and start reviewing the OSHA data, please go to Exposure Database. In the upper left corner is a tab called Data Home. Hover your cursor above that tab and a menu listing the way the data is displayed will appear.
You will also see the menu for any individual tab (Inspections, Substances or Establishments) by hovering over it.
Click on what you would like to see. Please be patient, as many of these displays contain a lot of records.
There you will be able to choose from a Google Maps-based app, or one based on Microsoft's Bing Maps. The functionality is approximately the same in both, but you may prefer one over the other.
Please select the year you wish to view by opening the Mapping Navigator and pressing the button labelled OSHA Maps by year and by state in the navigator, and selecting the desired study in the embedded table. This page, by default, opens to the most current year's inspections (2012), but you may view any data by any year, or for any specific U.S. state or territory you like.
The results are stated both quantitatively as average units of measures and qualitatively as an ordinal rank based on percent of PEL (the Permissible Exposure limit). Currently this includes over 500 substances.
The exposure history is supplemented by referenced toxicological and epidemiological information about the associations of specific exposure and risk of disease. In the event there is no human data, animal toxicological data pertaining to common human endpoints, such as cancer, respiratory, and nervous system, etc., will be referenced.
In order to view enforcement proceedings and fines, please refer to the Department of Labor Enforcement Database.
This website uses two different data sets, obtained from three sources:
1. “Analytical” data
Analytical data was obtained through 2 sources: from a Freedom of Information Act (FOIA) request, and by downloading a cleaned subset of this Salt Lake Technical Center (SLTC) data directly from the OSHA website. This data includes:
All data samples sent to the SLTC for analysis
Includes inspector ID
Does not include most of the data from State Plan states
2. “Inspection” data
Inspection data was obtained through an additional FOIA request. This is predominantly data from OSHA’s IMIS (Integrated Management Information System) database, with the most recent data from OIS – OSHA Information System. This data includes more of the data from State Plan states.
