COST STUDY ORGANIC VAPOR RESPIRATORS Increased usage of organic vapor respirators has created growing demands on supplies and labor along with increasing cost. Newly developed equipment has become available which will fulfill our needs with a minimum amount of labor, supplies and drive down cost. Our present Comfo II organic vapor respirators are used for one 8-hour shift and then exchanged. These used respirators are collected and prepared for re-use. This preparation involves complete disassembly; washing with cleaning agents; drying; replacing cartridges; inspecting by a safety inspector, re-assembling, sterilizing and sealing in a plastic bag. This tedious process is necessary to insure that the respirator is safe and efficient for use. A newly developed "one-way" or disposable respirator is now available. The unit is the 3M #8712 organic vapor respirator. The respirator would provide the same protection as the Comfo II. The results of a study of our in-plant usage has provided evidence that by using the new disposable masks we would benefit in an annual savings'of $2800. The attached chart outlines costs comparisons. DGW/sh February 28, 1978 David G.
