NIOSH Vision Statement
Delivering on the Nation’s Promise: Safety and Health at Work for All People…Through
Research and Prevention
![Page 6: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/6.jpg)
NIOSH Mission
To provide national and world leadership in the prevention of work-related illness, injury and death. We accomplish this by a scientific approach to gathering information, assembling and creating knowledge, translating it into products and services, and delivering it to all who can effect prevention.

Market Research
“It is our initial assessment that off-the-shelf laboratory information management systems (“LIMS”) designed for testing laboratories do not adequately fulfill the requirements...” as we know them.
![Page 11: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/11.jpg)
Purpose of Industry Day
• Enhance information given in the CBD
• Define the characteristics of an electronic database system for HELD
• Questions and answers
![Page 12: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/12.jpg)
Current Environment
• Diverse research environment: many techniques and technologies
• No centralized data collection facility• No standard backup/archival solution• Not all laboratory systems/instruments are
accessible from the Local Area Network• Proprietary file formats output by software
and instruments
![Page 13: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/13.jpg)
Database Project Concept
• Main “products” of HELD are reports and publications in the scientific literature
• Goal: Storage and retrieval of all processes and information that are relevant to the final reports and publications
![Page 14: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/14.jpg)
Scope of the Problem
There are currently 95 research projects being conducted in HELD.

• ASCII– Used for smaller data files.– Ease of viewing with text editors.
• Binary– Used for large data files to save drive space
• Mixtures– Header + Data
• Custom written files are used to extract data– Matlab, Labview, C, etc.
![Page 23: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/23.jpg)

Considerations
• Large range of file sizes (up to 80 MB).
• Extraction files must also be archived in order to make sense of data file and to calculate indexes derived from data.

• Environmental conditions
• Tool types, test devices and setup
• Test staff
• Technical notes and comments
• Etc.
![Page 34: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/34.jpg)

Data Recorded on a Tape
• A tape recorder is portable and convenient for a field test.
• It can be analog and digital signals
• The tape can only be replayed with the tape recorder.
• Analog signal will be digitized and processed using a software.
![Page 36: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/36.jpg)
Digitized Data Saved in a File• Many measurement devices come with their own
software and data are save in a file with a special format.
• In many cases, the file can only be read by a specific software.
• The data may also be saved in a ASCII format so that many other software can read it. However, An ASCII takes several times more memory and it is not desired.
• In most cases, we will keep the file in their original formats.

Exposure Assessment Branch in HELD
Are there physical and chemical surface properties that make certain particles more toxic than others?
We investigate this question by using various spectroscopy methods and HPLC:
NMRFTIRRamanAuger/XPSSEM/EDS/WDSHPLC
![Page 42: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/42.jpg)
Focusing in on just the SEM/EDS method.
We perform automated analysis of dust samples using commercial and custom software.
BrowsersSpreadsheetsWord processorJava, Perl and C-shell scripts
Data is generated and analyzed on UNIX systems and can be transferred via ftp to Windows systems for further analysis.
We use both Sun and SGI UNIX computers to perform the data analysis.
![Page 43: NIOSH Industry Day May 31, 2000 WELCOME. Administrative.](https://reader034.fdocuments.us/reader034/viewer/2022050714/56649d255503460f949fc57d/html5/thumbnails/43.jpg)
We use Exceed as the interface between the UNIX and Windows operating systems.
A typical automated dust analysis experiment generates text and SunOS RAS digital image files.
The amount of data generated is about 20 megabytes.
Data is currently being stored and archived on 1 gigabyte Jaz discs.
Most of our computer systems are connected to the Loca; Area Network.
