Guest guest Posted December 8, 2006 Report Share Posted December 8, 2006 Pat: Before I respond to your question, please, let me ask....When was the last time you donned a Level-B or Level-A biohazard suit to clean-up and remediate a contaminated site? This question is relevant to my response. Thanks. -- Geyer, PE, CIH, CSP President KERNTEC Industries, Inc. Bakersfield, California www.kerntecindustries.com , Don’t get ozone treatment and heat treatments mixed up. If you are saying, “using high amounts of ozone right before during sewage remediation is of benefit?” I would ask for your studies that support your position. In lengthy conversations with Dr. Spivak about 5 years ago and his studies, he concluded that gas-phase ozone doesn’t make a difference to the bio-load. The crap could care less that you are exposing its surface to ozone, bleach or any other topical disinfectant. Furthermore, NIOSH and EPA’s TWA/PEL involving worker exposure to ozone, at 0.1 ppm and 0.2 mg/m are far exceeded, when ozone to have any affect on sewage is unbelievable greater. How much of a worker exposure will we permit? How much ozone is necessary to make a biological difference in the kill-rate of organisms in the load? Now, getting to heat: You know I am a proponent of using heat, especially in situations where fresh water moisture damage can be eliminated before mold growth starts. However, the use of heat in sewage contaminated buildings “before remediation begins” may make sense in some cases and not others.

Pat: Both you and Pam make very good points. The point that Pam makes is so often overlooked/missed by those that tend to say that ozone is harmful. Pat, your comment that ozone does nothing for mitigating the source of the damage or the damage itself, hopefully, is rather obvious to us in the know. This said, if you were the person who was going into a sewage-contaminated building, would it not be somewhat comforting to know you were shoveling out and/or demolishing contaminated material that was first treated to reduce the bio-load? I’ve used heat for the same purpose, i.e., cook the _rap out of the Level-A biohazard before sending crews in to remediate the space. It makes a lot of sense when one is concerned for the poor slobs that have to do the grunt work. For what it is worth... Miichael Quote Link to comment Share on other sites More sharing options...
