great book if its ever needed. get an updated copy every year.

Great book, a new version should be standard equipment for every officer/patrol unit on the street!

A copy should be in every emergeny response vehicle.

great book, I keep one in my jump kit. I believe this year they are coming out with a new one....

Great to have, I keep a copy in the glovebox...never know when you'll need it.

All of our cars have them

these books are worth their weight in gold. they are free from your state haz mat agency

These are in all our vehicles. Highly recommended!

This is an obvious MUST-HAVE and/or SHOULD-HAVE for anyone in public safety. Whether you are a Communications Officer, Warrants Officer, EMS personnel, Firefighter, or Patrol Officer. Although it takes a litttle dedication to learn the process of using the book, the information contained is an invaluable assett and will without a doubt help save lives!!!!

Those trucks/trains/vans with that diamond shaped placard on the side are telling you in a code that this book deciphers, what dangers you are approaching...some materiels burn when exposed to air, others ignite when exposed to water, maybe that tractor trailor with the air-conditioning unit on it looks like it's leaking water due to condensation....or maybe you did a car stop on a truck that's leaking something caustic or lethal to inhale...this book will tell you what you are dealing with and exactly how to deal with it....

For my job this is a must

I have the 2008 version of this and it has come in very handy, exspecially when I was on the Fire Department.

Keep one in your car

Has very useful information.

every person got one.
