The principles of restoration as described by 1) Provide for the safety & Health of Workers and Occupants 2)
the S500 on a restoration project are... Inspect and Document the Project (initial / ongoing inspection /
final inspection) 3) Mitigate further Damage (control the spread of
contaminants, control the spread of water) 4) Clean & Dry
Affected Areas 5) Complete the Restoration & Repairs (remove
excess water, enhance evaporation, remove water vapor through
dehumidification and ventilation & control temperature)

buildings // they are often on national or local historical registries
and pose unique challenges
What other details are there about the outdated or inadequate power // funding issues // required
following type of building - historical buildings? approval by 3rd party organizations (e.g. historical registries) or
specialized experts (preservationists)
What is a critical step during the initial determin the potential for injury to employees or occupants
inspection...?
How can the size and complexity of fire sprinklers // computer server rooms and networks // multiple
mechanical HVAC systems vary...? HVAC zones // understanding the HVAC zones will help reduce
the potential for cross-contimination and help maintain drying
environment
What are the electrical designations? Volts/phase/hertz
What is an EMS? EMS = Energy Management System (aka building management
systems) // EMS cycle runtime of various systems to save energy
and may be managed off site / any changes would be
coordinated with building engineer // E systems can make
maintaining your drying environment more difficult, e.g. energy
recovery units, economizers)

source, does not pose substantial risk, e.g. water supply lines,
falling rainwater // Cat 2 = significant contamination and has the
potential to cause discomfort or sickness, e.g. overflows from
washing machines, broken aquariums // Cat 3 = grossly
contaminated... can cause significant adverse reactions (sewage
/ water back flows)
