We hear it all the timeafter 9/11, everything having
to do with security changed. It forced us to take a second look
at many things in our lives and it was natural to look at the
security of our critical infrastructure including roads,
waterways, airports and bridges. Of course, chemical security
had to be part of that. Lawmakers wanted to make sure that
companies using, making and storing chemicals were taking the
steps to secure their facilities and contents.
