It is very important to note that the function of each of the CIJ documents in the IMIRP Implementation Process remains the same as described in the IMIRP Implementation Guide. The IMIRP Implementation Process described in the IMIRP Implementation Guide should be used for all jobs covered by IMIRP. If you are familiar with the IMIRP Implementation Process and the use of supporting documentation, the format change for the twelve trades/maintenance jobs should not produce any difficulties. If you are unfamiliar with the process please read the IMIRP Implementation Guide before continuing. Notable Changes Overview The Overview only contains a Job Summary from each of the twelve trades/maintenance jobs. PDA The format of the PDA has changed so that a rehabilitation specialist, worker, and employer enter most of the relevant information. Some examples are provided to assist the users. The Task List contains all of the tasks seen or reported for the twelve trades/maintenance jobs. It is important to look through all of the tasks to indicate which a worker performs. Risk Factor Identification Checklist The format of the Risk Factor Identification Checklist has changed. The checklist contains relevant examples from the twelve trades/maintenance jobs and asks questions related to specific body parts. Work Manual The format of the Trades/Maintenance Work Manual combines some of the information in the Body Manual with the information normally found in the Work Manual. The Trades/Maintenance Work Manual is broken down into the seven identified body part areas. In terms of Injury Education, information is provided on the body part (Functional Anatomy, Body Mechanics), how injuries occur, and specific trades/maintenance job examples are given to illustrate how injuries occur based on different types of loading (Force, Repetition, Duration). In terms of Injury Prevention, general information is provided on how to prevent body part problems (Decrease Demands and/or Increase Capabilities), and examples are given as to how this may be achieved. The objective of the Work Manual is the same as in the past. In the trades/maintenance job format there are more concepts illustrated that may be applied to a job of interest. There are also job-specific solutions provided. Regardless of the source of solutions (i.e., solutions generated from an understanding of the illustrated concepts or from the job-specific examples), it is important to fill out the appropriate documentation.
