All PPE clothing and equipment should be of safe design and construction, and should be maintained in a clean and reliable fashion. Employers should take the fit and comfort of PPE into con- sideration when selecting appropriate items for their workplace. PPE that fits well and is comfortable to wear will encourage employee use of PPE. Most protective devices are available in multiple sizes and care should be taken to select the proper size for each employee. If several different types of PPE are worn together, make sure they are compatible. If PPE does not fit properly, it can make the difference between being safely covered or dangerously exposed | NCHRP REPORT 509 NATIONAL COOPERATIVE HIGHWAY RESEARCH PROGRAM Equipment for Collecting Traffic Load Data TRANSPORTATION RESEARCH BOARD OF THE NATIONAL ACADEMIES TRANSPORTATION RESEARCH BOARD EXECUTIVE COMMITTEE 2004 Membership as of January 2004 OFFICERS Chair Michael S.
