Below are a great selection of books from OSHA. These may be 20 – 100 pages and include items such as guides on what they require for training.
Note – I have included the pdf version, but if you go to the OSHA website, they also have MOBI and EPUB.
From the amazing people at WorkSafeBC. They are really good.
