Hello again I apologize for sending two messages, and also for the ambiguity of the message. I am currently working on developing ergonomic guidelines for engineering project development and management in the pulp and paper industry and logging industry. A lot of the activities involve maintenance work, and are highly variable. The focus of the guidelines would be to facilitate designs/redesigns that minimize the risk of injury. I am having difficulty starting the project. The scope is very large, and encompasses a large number of factors. Does anyone have any suggested starting points? Any references that I should look to? Any help would be appreciated. I also have another question... I am looking for evidence of the effectiveness of ergonomic training in changing behavior. Due to the high variability of employee work activities, making the worker adaptable to different situations is a must. Thanks. Tony %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
