Schools have been begging for an updated version of the California Science Safety Handbook since 2002.  The handbook was suppose to be updated once every three years, but that never happened.  Now after 13 years, the new book is here.   You can download a copy of the 2012 Science Safety Handbook here: http://www.cde.ca.gov/pd/ca/sc/documents/scisafebk2012.pdf
