Dexterity relative to glove materials that protect against chemicals was measured in college students performing the Bennett hand/tool dexterity test (HTDT). The participants were 20 college students ranging in age from 21 to 35 years. The HTDT measured proficiency in using ordinary mechanics' tools. The HTDT used a wooden structure with rows of holes for inserting three sizes of bolts and tightening them with washers. Each participant disassembled and assembled nine bolts per glove type with wrenches and screwdrivers while being barehanded or wearing one of three single glove types or while wearing one of six double glove types. Glove types were latex, viton, stansolv, and butyl. Performance was measured by time required to complete the task, with drops referred to as errors. Analysis of variance revealed that some tasks and some glove types required significantly more time to complete than others. Completion time for the 1/4 inch bolt was significantly slower than for the 1/2 inch or 5/16 inch bolts. Participants showed more errors in handling bolts and nuts as the size decreased. The barehand condition took a mean of 67.7 seconds (sec) to complete a task, followed by butyl (75.8sec), stansolv (79.7sec), latex/stansolv (80.8sec), viton (81.9sec), butyl/viton (90.7sec), and stansolv/viton (90.1sec). The butyl glove had the fewest number of drops. Participants rated the latex/stansolv glove the easiest double type to use. The authors conclude that glove type affects time required to perform the HTDT; double gloving reduces dexterity and increases error rates; and size of parts used affects errors.
