Looking to obtain a book for Advanced Hazmat Life Support (AHLS), unable to purchase this book from the organization until enrolled in the class. There are none in my locale, so waiting for approval from training department to attend an out of state class. Would like to study up before the class. If you can help please contact me at torozco@midlandtexas.gov, or leave message on forum. Thanks from your brother firefighter - fireman944.
