Abstract
Frequent impacts in industrial and academic research projects are reason for promoting the use of higher impact shields. An investigative study was conducted to determine and develop overall protective devices for workers who must search out, remove, and destroy hazardous substances. Plastics were evaluated and relative impact ratings established. Reinforced goggles and face shields were also tested. A cannon device was designed to control the flight of glass missiles. Charges simulated forceful laboratory explosions. The broken glass was made from typical bottles and flasks to determine the effectiveness of the shields. Results indicate that commonly used face shields should be replaced with a very wide and long polycarbonate window. Reinforcement is made by adding a second layer of the polycarbonate separated by one nut for each four bolts. For routine laboratory work, the auxiliary outer window may be removed to make the shield lighter and therefore more comfortable. The shield would still afford high impact resistance. Impact tests were made using a glass missiles "cannon"; all polycarbonate outer windows were severely roughened by cracked glass missiles, but never filed by shattering or cracking.
