E. T. Hawkins to J-M Plant Managers on the Use of Protective Equipment (1967)

A one-page memo of October 12, 1967, from E. T. Hawkins at J-M's Research and Engineering Center to the managers of 14 J-M plants, from Alexandria and Manville to Marrero and Waukegan, on the "Use of Protective Equipment." In areas "where noise levels or dust concentration dictate," workers already had ear muffs or respirators; now "all persons entering such areas" were to be given them. A supply was to be kept for supervisors, maintenance staff and other plant people, and for "all plant visitors whether from Johns-Manville or outside the company."
