Walking and Working Surfaces
8555WalkingandWorkingSurfaces andMaterials HandlingandStorage Report
Prepare a project report using the attached Unit V Consulting Report template for your project, and complete the template
based on following information:
Part I: Discuss the nine items to check when conducting a ladder inspection.
Part II: There is an elevated area within the plant that requires two maintenance personnel at least once every 2 weeks to
access and perform preventive maintenance by lubricating the gears and pulleys. They are currently using a 20-foot
extension ladder to reach the locations that require maintenance. This requires that the ladder be moved six times per
event, along with one of the employees climbing up and down the ladder. The maintenance supervisor for the plant has
provided a drawing of a proposed elevated platform (catwalk) that he would like to install and has asked you to review them
for compliance with Occupational Safety and Health Administration (OSHA) standards and to identify any potential problems
with the design. See Figure 5.1 below:
Figure 5.1: Elevated Working Platform (proposed design)(SEE ATTACHEMENT)
In its current design, the platform is 22 feet wide. The side force is capable of withstanding 155 lbs. of side force. The
thickness of the top rail and vertical support is 0.20 inches. Review Figure 5.1 and provide recommended design
modifications to ensure that the proposed elevated working platform meets the requirements of 29 CFR 1910.28 and 29
CFR 1910.29.
Part III: Maintenance employees are required to wear personal fall arrest systems (PFAS) when working on a scaffold. The
scaffold is 15 feet off the ground floor. The employees have been provided with a PFAS, which includes a 5-foot shockabsorbing lanyard, meaning that once deployed it will extend an additional 3 feet (for a total of 8 feet). The tallest employee
working on the scaffold is 6 ft. 2 in. Calculate the minimum safe distance for this PFAS and determine if this is the correct
lanyard to prevent an employee injury.
Part IV: Several employees have been assigned to clean up bulk materials following a train derailment incident using scoop
shovels. The scoop shovel will hold approximately 28 lbs. of bulk material, and the scoop lift is approximately 36 inches
(distance from the ground to the container). Using the information on pages 648–650 and Table 28.1 of your textbook,
determine the recommended scoop rate before the employee should take a rest break.
Ensure you address all parts of the template. Your project should be a minimum three-page report using the above
template. Ensure you show your equations and all work for determining answers for Parts III and IV in the project document.
You may either formulate the scenario equations using the Word equation formula toolbar or write out and solve your
equations with answers on a separate paper. Then, take a screenshot of your work for each scenario using your phone or
similar device and insert it as an image in the document. Make sure your image is clear and legible to read.
