PRELIMENARY EVALUATION OFVISIBILITY IN HAZARDOUS MATERIALS LEVEL A SUIT

摘要

This paper evaluated the problem of visibility of a hazardous materials (hazmat)responder while wearing a level A hazmat suit. An experiment was performed to judgethe amount of time a level A hazmat suit can be worn in normal working conditionswithout fogging and reducing visibility. After an initial evaluation, hypothesis andalternatives to prevent the fogging of the suit were formed. An experiment was performedtesting the alternatives of antifogging agents to physical moisture barriers. From theexperiment, a short-term solution, the use of anti-fog spray, and a long-term solution, theuse of a cone shaped moisture barrier, were formed to correct the visibility problemfacing the users of this suit.
