Thank you for looking! I purchased this new about 4 years ago. I read it a bit for work and have kept it at home since. There's a crease on the cover, but the inside is in good condition. There are no markings or writing inside. Thank you very much! An important safety guidebook summarizing the knowledge and behavioral guidelines required in the field.
