Foreword
This slideshow was assembled by Lorenzo Lopez with assistance from Jeffrey Maddox to organize the changes t th 2013 C d C l hi h ff t j ti f iliti Thto the 2013 Code Cycle which affect justice facilities. The official report can be found on the California Office of the State Fire Marshal at: h // f fi / d d l / df/Ihttp://osfm.fire.ca.gov/codedevelopment/pdf/I-3%20Occupancy/I-3_Final_Report.pdf
The proposed changes in the link above have been adopted by the California Building Standards Commission and should be published in July of 2013. The report from the link above records these changes in numerical order of code section starting with Section 202 gfor definitions and ending with Section 1028.1.
Foreword
Because the fire and life safety issues the I-3 Task Group addressed affect multiple code sections (which are not in
d ) thi lid h th h t th border) this slideshow groups the changes together by issue in order to assist with understanding those changes.
This slide show did not address the various modifications to definitions which should be self explanatory.
The slideshow presented on March 13th 2013 to the Academy of Architecture for Justice begins on the following slide.
Feel free to contact Lorenzo Lopez at [email protected] with questions.
