  3. Quotes for the Day • “Learning is what you remember after you’ve forgotten all you heard.” • “Credibility is like credit once it’s lost it is difficult to restore.”

  4. Rapid Structural Drying Continuing Education Instructor: Bruce Vogt • IICRC Certified in: • Water Damage Restoration • Fire & Smoke Restoration • Carpet Cleaning • Odor Control • Member of National Speakers Association

  5. Bruce Vogt • Consultant to U.S. Military • Consultant to Hotel/Motel • Consultant to Manufacturing Facilities, Plants, Factories, Warehouses • Hospitals • Smithsonian Institute • “Marketing By Delight”

  6. Objectives • Provide licensee with information they can use to protect the health, welfare and safety of the policyholder. • Provide licensee with information they can use to reduce the cost of the loss.

  7. Objectives • Review Current State of the Restoration Industry • Review Industry Standards • Review Principles of Drying • Review Psychrometry – The Science of Drying • Review Documentation • Review Benefits of Rapid Structural Drying

  8. Brief History • Initially water damage restoration was performed by carpet cleaning companies. • The primary focus on drying the carpet. • Average residential job took 5 – 6 days to dry and put back together. • Specialized equipment and training was first introduced to industry in the late 70’s. • There was little concern about mold. We thought we could spray biocide and mold would not be a problem.

  10. IICRC S500 Water Damage Standard

  11. S500 provides a procedural standard for use by those involved in the water damage restoration industry. The Standard is technically consistent with the knowledge available at the publication date. To Obtain A Copy Contact The IICRC At: 360-693-5675

  12. IICRC S500- 1994 • First water damage standard. • Total Pages - 75 • Introduced categories of water damage. • Specified one airmover per 400-500 square feet. • No specification for dehumidifier placement. • Recommended biocides for all jobs.

  13. IICRC S500 - 1999 • Total Pages -100 • Provided guidelines for cushion replacement. • Provided consideration for biocide application. • More details on the potential of microorganisms. • No equipment placement recommendations. • More emphasis on health & safety.

  14. IICRC S500-2006 • Total Pages-357 • Classes of Water Damage • Calculations for Dehumidifiers • One Airmover for every 10 to 16 linear feet. • Heat Drying • Large Loss & Cat Losses • W.E.T Study

  15. IICRC S520 Mold Remediation Standard

  16. Certification Card

  17. Important Definitions • Shall • When the term shall is used, it means that the practice or procedure is mandatory due to natural law or regulatory requirement, including occupational, public health and other relevant laws, rules or regulations, and is therefore a component of the accepted “standard of care” to be followed.

  18. Important Definitions • Should • When the term should is used, it means that the practice or procedure is a component of the accepted “standard of care” to be followed, while not mandatory by regulatory requirements.

  19. Important Definitions • Recommended • When the term recommended is used, it means that the practice or procedure is advised or suggested, but is not a component of the accepted “standard of care” to be followed.

  20. Important Definitions • May • When the term mayis used in the S500 it signifies permission expressed by the document, and means that a referenced practice or procedure is permissible within the limits of this document, but is not a component of the accepted “standard of care” to be followed.

  21. Important Definitions • Can • When the term canis used in the S500, it signifies an ability or possibility open to a user of the document, and it means that a referenced practice or procedure is possible or capable of application, but is not a component of the accepted “standard of care” to be followed.

  22. Categories of Water in Water Damage • Category 1 - Clean Water • Clean water originates from a source that does not pose substantial harm to humans.

  23. Categories of Water in Water Damage • Category 2 - Gray Water • Gray water contains a significant level of contamination and has the potential to cause discomfort or sickness if consumed by or exposed to humans.

  24. Categories of Water in Water Damage • Category 3 – Black Water • Contains pathogenic agents and is grossly unsanitary. • Sewage and all forms of flooding from sea water, ground surface water and rising water from rivers & streams. • Toilet back flows that originate from beyond the toilet trap are considered black water.

  30. Questions To Ask Mitigation Contractor • Are You Certified In Water Damage Restoration? • Can You Show Me Your ID Card? • Are Your Technicians Certified In Water Damage Restoration? • Is Your Firm Certified? • Does Your Company Follow The Standards Outlined In IICRC S500?

  31. Technicians Should Ask These Questions • What Is Wet? • How Wet Is It? • What Is the Best Way to Dry It?

  32. Moisture Detection Equipment • Hydro-Sensor • Used to determine the exact perimeter of damage to carpet and cushion.

  33. Moisture Meters

  34. Moisture MetersUsed To Measure Moisture Contained In Structural Materials • Non-Penetrating • Used to detect moisture under sheet vinyl, wood, ceramic tile, etc. • Penetrating • Used to detect moisture inside materials, examples, sub-floors, hardwood floors, etc.

  36. Moisture Meter Scale

  37. Principles of Drying • Principle 1 - Excess Water Removal • Thorough extraction not only contains damage, it considerably speeds up the drying process. • Removing water physically can be 500 times more efficient than removing water by evaporation and dehumidification.

  38. Excess Water Removal • Absorb water that’s standing on contents and fixtures by mopping or soaking up with absorbent cloths. • Drain water out of ceiling or wall cavities. • Extract water from floor coverings. • Pump standing water from below-grade areas (i.e. basements, crawlspaces).

  39. Portable vs. Truck Mount THEN NOW

  40. ONLY Truckmount Should Be Used On Water Damage Loss • TMs are much more efficient than portable units. • TMs use 2” hoses. Portables use 1.5” hoses which provide 45% less airflow. • TM’s have 60+ gallons of recovery. Portables have 5 to 10 gallons of recovery. • 500 times easier to physically remove the water than evaporate & dehumidify it.

  41. Extraction Updates • For every 50 ft of hose you lose 50 CFM • Dual wands reduce the CFM 50% • Keep hoses straight • Make a 25 ft length to use with a 50 ft length • Unit must be 2” all the way through

  42. CARPET WET TESTING CONCLUSIONS • Wet carpet experiences more adhesive strength loss than previously thought by the industry. Instead of 30-50% loss, it appears to be more like 70-83%. • Based on samples tested after being wet for 48 hours, the longer the carpet dries, the stronger the adhesive becomes – even to the point that it exceeds the original dry sample. • Surface drying requires more carefully controlled conditions and provides cost and productivity advantages.

  45. Extraction Efficiency • Pad Test – detach carpet from wall in one corner of affected area after extraction and squeeze the pad with your hand. Extraction is complete when no water can be squeezed out of pad. • Different carpets & pads release water differently. For example, cut pile carpet releases water easier than Berber carpet. • Carpet & pad are very porous. Once properly extracted they dry very easily.
