Developing A Taxonomy Of Ladder Climbing Techniques, Charles Holland
Developing A Taxonomy Of Ladder Climbing Techniques, Charles Holland
Graduate Theses & Non-Theses
The research found on ladder safety indicated broad recognition of the hazards of using ladders, especially in the construction industries. OSHA regulations, as well as general guidance on ladder safety point to training workers on ladder usage techniques as being one of the most useful means of reducing risk of falling. However, no studies could be found directly investigating different techniques for ascending and descending ladders. In order to study and compare techniques, this project was initiated to establish a taxonomy of techniques for climbing and descending ladders Six patterns were hypothesized. A secondary purpose was to compare the patterns …
Effect Of Repetition On Time To Don And Adjust A Fall Protection Harness, Zachary Bunney
Effect Of Repetition On Time To Don And Adjust A Fall Protection Harness, Zachary Bunney
Graduate Theses & Non-Theses
A major concern in the field of occupational safety and health is the fatalities resulting from falling from heights. In the construction industry, a common approach for protecting workers is the use of a fall protection harness connected to a secure anchor. To be effective, harnesses must be fitted and adjusted to the individual. This requires training on adjusting the straps of a harness, and the training must include practice to ensure the worker has the skills to make a secure fit. It would be useful for those who conduct training on harness fitting to know if trainees would benefit …
Static Shoulder Elevation With Or Without Limited Range Of Arm Motion, Kayla Ericson
Static Shoulder Elevation With Or Without Limited Range Of Arm Motion, Kayla Ericson
Graduate Theses & Non-Theses
Purpose: The purpose of this study was to investigate the effect of two similar low force, upper arm holding tasks on shoulder muscle fatigue. One task involves static holding, while the comparison task involves limited up and down motions, dynamic rolling. Both tasks require the shoulder muscles to hold the combined weight of the arm, hand, and a roller brush in a manner similar to that of a painter standing on a portable ladder painting a wall.
Methods: Twenty volunteer participants from undergraduate classes performed two similar tasks. One was holding their dominant arm above their shoulder while holding a …
