ABSTRACT:
BACKGROUND OF THE INVENTION
In environments where hazardous materials are handled by personnel, such as in laboratories, hospitals or industrial environments, immediate access to emergency treatment and materials containment procedures can be critical. Appropriate steps to minimize health risks associated with a chemical, biological or radioactive material spill must be taken immediately to prevent collateral harm.
There currently does not exist a sign book for displaying safety information in an optimum format for emergency reference. The prior art relies on large cumbersome reference manuals that are often stored on remote bookshelves or in offices. Prior art designs do not provide adequate visual display and convenience of page turning for emergency situations.
What is needed in the art is an informational sign book that can be readily displayed and accessed in a hospital, laboratory or industrial environment. What is needed is a safety sign book that permits users to quickly locate and review emergency procedure information with a minimal amount of effort.
SUMMARY OF THE INVENTION
The present invention provides a book for vertically displaying safety information on selected pages. The book is particularly well-suited for use in laboratory, hospital and industrial environments where emergency situations can prevent access to remote reference manuals. The book has front and back covers with a releasable mounting means for mounting the book in a vertical position on a planar surface. The book also has a plurality of adjacent informational pages releasably adhered together, and a binder.
