Problem book for Fire Equipment Technician exam preparation, revised 2nd edition. - Title: Class 2 Fire Equipment Technician Written & Practical Breakthrough Study, Revised 2nd Edition - Publisher: Ohmsha - Version: Revised 2nd Edition - Content: Problem book for Fire Equipment Technician exam preparation Thank you for viewing. I read it with a cover, so the book itself is in good condition, I think. Regarding the contents, there are many places with writing and markings. I found them helpful when I reviewed the material, so I will pass it on as is, but since everything is in pencil or friction pen, you should be able to erase them to a less noticeable state.
