Recent storms throughout the United States have caused a large number of issues. A big problem is the presence of biological pathogens found in structures with floodwater damage. Concerns about health call for a method to supply safe and effective disinfection of buildings and structures that have been affected by floodwaters. Pasteurization, a method used with success for one hundred fifty years in food products, will be applied for disinfection to structures. By reaching temperatures fatal to most of the pathogens related to floodwater contamination, Rest Easy Mold Control can pasteurize structures.
Every remediation and/or drying project in an exceedingly flooded structure should assume contamination. Rest Easy Mold Control offers a very thorough disinfection process with the ability to penetrate inaccessible areas with efficient targeting. This method doesn’t use chemicals or biocides and thus the area has no additional hazards added. This unique disinfectant process totally dries the structure and kills the unwanted pathogens and their insect vectors within the same treatment.
Floodwater with Environmental Problems
Extensive flooding creates vital environmental health issues. The potential contaminants in floodwaters embrace a range of biological pathogens. Providing a health threat that is ongoing, several of those pathogens will stay viable for months in a structure. Some will stay longer in an exceedingly damp atmosphere. As structures dry, several become aerosolized in the building and migrate within. Rodents and insects can act as vectors transporting these pathogens throughout a structure. Disinfection of pathogens in flooded structures could be an advanced and stringent drawback.
Floodwaters have non-biological contamination issues similarly. Gasoline, pesticides and different chemicals could also be carried by water into structures. The volatile organic compounds (VOCs) related to several of those chemicals present a possible hazard to occupants as they slowly off-gas over subsequent many months.
Hazards in Floodwater
Pathogens found in buildings plagued by sewage-impacted floodwaters embrace microorganism, viruses, protozoa, and helminthes. Per the globe Health Organization (WHO) these pathogens impact human health. Listed in these categories are a number of the additional important pathogens.

Occupants of flooded structures can be affected by a wide variety of routes and vectors making the resolution more complex. Rest Easy Mold Control’s Heat Process is the only process that effectively treats all of the pathogens present as well as impacting the vectors and routes.
High Temperature is an Effective Disinfection Process
Temperature is a more thorough intervention process in the inactivation of enteric pathogens. According to the WHO, “…heating to pasteurization temperatures (generally 60°C/140°F) for periods of minutes to tens of minutes will destroy most waterborne pathogens of concern”. This general statement may be adequate to recommend utilization of heat for the disinfection of floodwater-impacted structures.
The process of pasteurization of a structure appears to uniformly impact these pathogens related to floodwaters. Other methods of disinfection are not as uniform in result. For example, Giardia cysts are resistant to chlorination and a wide range of pH. Studies have shown human rotovirus to be resistant to a wide variety of chemical disinfectants. Other methods may not be ovacidal, for example in the case of helminthes the eggs of Ascaris are more resistant than the larvae. Many disinfection processes are not as safe and are not as effective. Heat, as a disinfectant, is uniform and non-discriminatory in application. Pasteurization of a building is an effective process to reduce pathogens to safe levels.
The efficacy of Rest Easy Mold Control’s Heat Process in a nutshell is the results of the mix of temperature and time. The hard part about disinfection is achieving efficiency across the entire structure. What differentiates our process is the ability to entirely disinfect the structure as well as inaccessible areas. Buildings are complicated and the demand for uniform temperature throughout a structure is critical to attain the highest efficiency. Heat technicians are completely trained in construction materials, thermal dynamics and the intended targets. Buildings have materials that conduct heat, that make radiant losses, and are heat sinks. The technician should perceive every of those conditions as well as others. Temperatures are Real-time monitored in troublesome to heat locations. In a structure that is wooden these places can be underneath sill plates and between header boards. Crawlspaces and sub-areas give further difficulties. Rest Easy Mold Control will treat all structures.
