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. A complete copy of the FEMA report may be found on the DUI website: http://www.dui online. com/pdf/fema_report_excert.pdf


The results for the permeation resistance of Red/Black PU laminated fabric, as assessed by ASTM F739-07 are summarized in Table 1 below. The data reports the initial breakthrough time (first when the lowest detectable permeation rate is evident), the normalized breakthrough time (first when the permeation rate of 0.1ìg/cm2 /min for open loop system is detected), and the Steady State Permeation Rate are reported. During the 480 minutes test period, if a stable permeation rate was not reached, the Steady State Permeation Rate was not calculated. The cumulative permeation (<6.0ìg in 1 hour period), as outlined in the NFPA 1951-07, section 845.4; “Chemical Permeation Resistance” was used as the pass/fail criteria for the fabric.

The DUI CXO drysuit is designed to be worn as a completely encapsulating unit, with attached gloves and attached hood in combination with a full face mask, in order to minimize diver contact with hazardous materials. Contaminated water diving requires specialized training. The DUI Drysuit Owner’s Manual and the DUI CXO Drysuit Owner’s Manual covers only the basics of drysuit functions and care. It should not be used as a substitute for drysuit instruction, OSHA HAZWOPER courses or contaminated water dive training. It is important for the user to understand that exposure protection does not eliminate the risks associated with contaminated water diving.

When used properly, as part of a complete hazardous diving program which should include all steps for planning through definitive decontamination, the use of a drysuit may minimize these risks. Please seek proper professional instruction when diving in contaminated water.

What DUI CXO drysuit owners have to say…

Woody Morrison DUI CXO drysuitI’ve had my current CXO drysuit for 2 years now and have abused it beyond my normal levels. I’ve slid over rusty metal, climbed countless ladders, took two 10’ falls in full gear, repelled down the side of a damn and been overly verbally abusive with it. I even had a 300 gallon-per-minute suction hose clamp down on it; gotta say the drysuit fared far better than my leg did. It at least worked the next day. The suit is on dive #1013 and has over 2500 underwater hours on it, plus a few lunches above water.
