Introduction

Objective - To identify the classification of chemicals based on the

hazardous lists issued by different countries.

The lists selected for developing the software are:

Hazardous chemicals list given by U.S. E.P.A.

Europe’s List of Notified Chemical Substances.

UK List of approved workplace exposure limits.

Hazardous Substances Information System (Australia).

Introduction contd… This tool brings together chemicals from four different lists and combines them

into one tool so that users can use the tool with ease to identify the

classification of chemicals.

The properties and the limiting values of the chemical are also provided as

output for every chemical in the tool to help users understand completely about

any particular chemical.

This tool helps the industries in identifying the list of hazardous chemicals

listed by different countries.

Methodology Adopted for Developing CIS 1.0

The lists are obtained from the literature to develop CIS 1.0.

Chemicals from the selected four different lists were entered into a column and

then clubbed together in same column while classification is done using four

other columns.

The properties and the limiting values of chemicals are entered in different

columns such that they can be easily accessed while using the forms which

provide the output of the tool.

Development of CIS 1.0

The chemicals are entered into Microsoft Access database such that the chemical name, the lists in which chemical is present, properties, and limiting value are in different columns.

The forms are designed in such a way that when a chemical is selected from the drop-down list, the corresponding lists in which the chemical is present, properties and limiting value will be displayed in their respective boxes.

Output of CIS 1.0The output of CIS 1.0 software displays the following:

the lists in which the chemical is present.

the properties of the chemical (obtained from MSDS

sheets).

the limiting values of the chemical.

UsesHelps to bifurcate a chemical from hazardous chemicals.

Obtain the limiting value of any required hazardous chemical.

Helps in selection of a chemical before it is used in any manufacturing technique.

Helps industries identify hazardous chemicals before any trading between different countries.
