This exposure coding system was developed by Katherine Hunting, PhD, MPH and Susan McDonald, MS, CIH of George Washington University's Occupational Medicine Group, for the Association of Occupational and Environmental Clinics (AOEC), with support through NIOSH Cooperative Agreements U60/CCU306169 and U50/CCU309667.
 
 

	On-line Instant Look-up, new 5/00 Questions on this new feature?: Gary Greenberg This online engine will generate a list of matching codes for any character string entered.  Eg: Type: "methane" and your results you'll find will be formatted like this:   AOEC Code Chemical Name Common Name Categorical Code A = Asthmagen S = Solvent P = Pesticide 250.16 4,4-Diaminodiphenylmethane MDA .    . 191.03 Bromomethane Methyl Bromide .    P 260.23 Diazomethane Diazomethane .    . 190.09 Dichloromethane Methylene Chloride .    S 221.02 Diphenylmethane Diisocyanate Methylene Diisocyanate A    . 100.06 Ethoxymethane Ethyl Methyl Ether .    . 060.06 Methane Methane .    . 191.03 Monobromomethane Methyl Bromide .    P 260.14 Nitromethane Nitroparaffins .    . 160.02 Phenylmethane Toluene .    S 190.01 Tetrachloromethane Carbon Tetrachloride .    S 190.03 Trichloromethane Chloroform .    . 260.06 Trichloronitromethane Chloropicrin .    P
	Search for: case insensitive Case Sensitive  Searches can include: Physical agents (eg radiation), chemical classes (eg. hydrocarbons), activities (eg repetitive movement) Once you find a particular code, you may want to enter the non-decimal portion again, to see the whole class, eg 260 for Diisocyanate agents.
	For offline lookups, the data and a search tool are combined into packages for downloading, using the commonly available PKZIP program, which compresses and combines data files into tight bundles.  This allows more accurate and faster data exchange over communcations channels. Many other programs are available to un-pack these bundles, even for Windows, Macintosh and Unix systems. The AOEC Exposure Code Lookup Program runs on DOS-based computers, without need for your own database program. This un-zips to become an executable file and includes both indices and the actual dBase files. Instructions for receiving and installing these files are below. The codes themselves, in table format, are available as ASCII text, as WordPerfect formatted documents, or as MS-Word formatted documents. Each of these include 2 files each and are ZIP'd together for compression and speed for downloading. A categorical structure of the codes is available for web-viewing here. Simply curious how it works? A sample page, encoded into HTML for web-viewing is also available in this web-area.

Instructions (from AOEC's office staff):

AOEC Exposure Code LookUp

1. Before accessing the AOEC Web page, create a directory on the PC hard drive (we suggest Lookup) to establish a location where the programs will be downloaded.

2. If you already have the PKUNZIP program, move a copy to that directory. (If you do not have PKUNZIP, continue to the next step.)

3. Once on the AOEC web site you will need to click on to the area which says AOEC Exposure Code Look-Up Program.  Download AOEC-COD.ZIP to the directory you have created.  If you don't have PKUNZIP, move the curser to PKZIP program (contains both zip and unzip programs) and download that file into the directory as well.

4. Exit the Web site.

5. From DOS change into the directory you have downloaded the program into and perform the following steps:

 cd \lookup <enter>
 pkunzip aoec-cod.zip <enter>
 lookup <enter>

6. For Window users: Go into File Manager.
 Associate AOEC-COD.ZIP with PKUNZIP.EXE.
While still in File Manager window click on LOOKUP.EXE, this will take you directly to the exposure code keyword search facility.
