Primary Decision Criteria

• Category of water - Clean - Gray - Black
• Class - Level of saturation and the optimum rate
  of evaporation
• Time - Amplification of micro-organisms
• Temperature - Frigid to Hot
• Humidity - Water Vapor
• Resources Trained Labor and the best
  available Drying Equipment
• Changing the outcome constraints

3
WET goes to DRY quickly with proper aggressive
drying methods

Initial Response Focus on Primary Decision
Criteria

• Primary Decision Criteria
• Gather information
• Conduct an inspection
• Communicate to qualified individuals
• Provide initial procedures
• Decision-making
• Task performance
• Safety concerns materials, microbial
  contamination

5
Benefit from todaysH2O as EASY as 1, 2, 3

• Minimize interruption and plan for contingencies.
• Ask questions and evaluate the answers
• Act decisively with defined goals
• Consult with an experienced professional
• Better qualified to make or not make a decision
  in a time of crisis!
• Understand ramifications of actions or lack of
  action. Prioritization or Procrastination

6
Water and Fire Mitigation
Crews, vehicles and equipment ready to respond24
hours a day, 7 days a week. For losses large to
small its as easy as 1, 2, 3
7
Gathering information

• Age of building and past history of the building
• Odors
• Materials
• Contents
• Systems - Electrical, HVAC, Phone, Data
• Use of the building
• Occupants - number of and needs of
• Interruption effects

Giertsen Company uses FLIR infrared thermal
imaging to identify moisture that would otherwise
be invisible to the naked eye. This tool allows
us to assess damage and start the drying process
immediately and monitor progress.
9
Conduct an Inspection

• What is the source?
• Map the moisture paths
• Adjoining spaces?
• Likelihood of second occurrence?
• Moisture detection devices?

Categories of Water
Category 1 (Clean)
Category 2 (Gray)
Category 3 (Black)

• Contains significant contamination
• Has potential to cause sickness if consumed by
  humans
• Can contain unsafe levels of microorganisms as
  well as other organic or inorganic materials
• Examples Discharge from dishwashers
  Overflows from soiled toilet bowls Seepage due
  to hydrostatic press. Broken aquariums
  Punctured water beds
• Category 2 water cleanliness can deteriorate
  for many reasons contact with building
  materials, systems and contents

• Grossly contaminated
• Can contain pathogenic, toxigenic or other
  harmful agents
• Examples Sewage Toilet backflows from
  beyond trap Ground surface water Water from
  rivers or streams Wind-driven rain from heavy
  storms
• Such water may contain silt, organic matter,
  pesticides, heavy metals, regulated metals, or
  toxic organic substances

• Originates from Sanitary Water Source
• No substantial risk from exposure
• Examples Broken water supply line Tub or
  sink overflow Broken toilet tanks Appliance
  malfunctions Melting ice or snow Falling
  rainfall
• Once Category 1 water leaves the exit point,
  it may not remain clean once it contacts other
  surfaces or materials.

The cleanliness of water changes over time and
requires a prompt response! Proper and aggressive
drying methods hinder amplification!

Classes of water

• Class 1 (least amount of water, absorption and
  evaporation)
• Water losses that affect only part of a room or
  area
• Large areas with materials that have absorbed
  minimal moisture
• Little or no wet carpet and/or cushion present

• Class 2 (large amount of water, absorption and
  evaporation)
• Water losses that affect at least an entire room
  of carpet and cushion
• Water has wicked up walls less than 24
• Moisture remaining in structural materials

• Class 3 (greatest amount of water, absorption and
  evaporation)
• Water may have come from overhead
• Ceilings, walls, insulation, carpet, cushion and
  sub-floor saturated

• Class 4 (specialty drying situations)
• Consist of wet materials with very low
  permeance/porosity
• Hardwood, plaster, brick, concrete, lightweight
  concrete and stone
• Typically deep pockets of saturation which
  require very low specific humidity
• May require longer drying times and special
  methods

14
Emergency Service vs. Mitigation

• 24-Hour Emergency Service
• Water Mitigation
• Board-up/Security
• Dehumidification
• Monitoring Equipment
• Temp power and heat
• Deodorization
• Thermal Imaging
• Commercial Drying
• One Hour Response

15
Provide Initial Procedures

• Establish drying goals and document progress of
  efforts or lack of!
• Primary affected areas structure, contents, and
  systems
• Specific goals - to be determined
• The clock is ticking Migration, intrusion,
  contamination, secondary damage, corrosion,
  wicking, loss of use, interruption of day-to-day
  functions
• Communicate to qualified parties

16
Category 1, Class 4, 2 days
Proper Aggressive Drying Methods
17
Decision-making and Implementation

• Requirements to go from wet to dry without
  increased costs and liability
• Active hands-on.
• Time commitment required to be actively involved.
• Trade-offs occur. Focus on wet to dry and time
  required.
• Decide and implement! Re-evaluate .

Giertsen Company Specialty Circumstances Day 2
Class 3 Category 1
Giertsen Company utilizes the Injectidry system.
Injectidry forces dry air into wall cavities
where standard fans are not effective. This
minimizes the amount of demolition required in
order to dry properly.
