A Must Have

Ive been a firefighter for 25 years and I work for the railroad as a conductor. This app is extremely fast and helpful in both jobs. As a conductor, the possibility of carrying large amounts of HazMat is high. To have this app along with the other guides I have to have is very convenient and saves a lot of space. Best of all, I can find what I need faster with the app than with the book.
