Fire Protection Equipment Technician Exam Preparation Example Collection Fire Protection Equipment Technician Textbook Class 6 Set of 2. Both have writing inside. The textbook has lines drawn and notes written in the parts indicated during the training session. The problem collection does not have answers written in, but the corners of pages with frequently appearing problem types are folded, and some problem numbers are marked. Not all problems, but some important points in the problem statements have been underlined. Overall, there is a sense of use, but I think they can still be used. Please purchase only if you understand that these are used items.
