I believe that the most fitting answer for this question would be the safety manual. The dictionary will not help you, as it can only provide you with the meanings to different words. The encyclopedia will not help you, as it can only give you information on a number of subjects and cannot tell you what your company's policies are. Your employee handbook will typically only have the duties expected of you as an employee. The safety manual will include everything you need to know about safety on the job. Hope this helps.
