The Utility of Brief, On-Product Instructional Labels for a Fall Arrest Restraint Device

Abstract

Fall arrest restraint devices for hunters are sometimes confusing to assemble due to the similarity of components; yet erroneous application can prove fatal. While assembly instructions are typically provided, they may not be available at the time of use. This study investigated the utility of adding brief, on-product instructional labels to a fall arrest restraint device. It was hypothesized that the addition of such labels would increase the rate of correct assembly over unlabeled restraints, and be about as effective as restraints provided with full instructions. Fifty-nine subjects were randomly assigned to one of three groups: (1) Restraint Only; (2) Restraint + Labels; (3) Restraint + Instructions. Labeled restraints produced more correct assemblies than unlabeled restraints; however, this finding was non-significant. While labels facilitated one aspect of assembly, they did not lead to improved overall assembly relative to restraints provided with instructions. Those receiving instructions performed significantly better than the other two groups. Many subjects receiving instructions were observed to rely largely on illustrations, rather than text. Results suggest that for products where assembly is non-intuitive, brief on-product identification labels may not be sufficient to guide proper assembly. Further, given that some consumers will not consult instructions or instructions may become separated from the product, manufacturers should strive toward intuitive designs.
