Permeation test results of CXO polyurethane material provided by ICS Inc. Laboratories, Brunswick, Ohio

The chemicals that were selected for testing were the same chemicals tested in FEMA’s comparative study in 1993:

Protective Clothing and Equipment Needs of Emergency Responders for Urban Search and Rescue Missions. FEMA selected these 5 chemicals as representatives of the chemicals most likely to be encountered by divers. Selected chemicals are not water reactive, have vapor pressures less than 250mm Hg (which means they will not evaporate spontaneously) and are miscible in water. As in the FEMA study, chemicals were tested in a concentration equal to their maximum solubility in water up to a concentration of 10% which represented the extreme limit of exposure.
