Category of water refers to_____________________ - ✔️✔️The range of
contamination in the water
Who determines the Category of water?__________________________ - ✔️✔️The
restorer
Classes of water refers to _______ - ✔️✔️An approximation of the degree of water
absorption and evaporation
A dry standard is_______________ - ✔️✔️Approximation of the MC/ML of materials
prior to the water intrusion
Drying goals are_________ - ✔️✔️Target MC/ML of materials after water intrusion
The drying goals should be set that would be expected to:___________ and -
✔️✔️Return structure, systems or contents to an acceptable condition and inhibit
,microbial growth
The first principle of restoration as described by the S500 on a restoration project is to
_____ - ✔️✔️Account for the health and safety of occupants
Describe at least three characteristics of commercial drying projects that make it
different from typical residential ones - ✔️✔️Complex wiring
Public access and security
Multiple stakeholders
Electrical power
Complex construction,materials, codes
The S500 describes Commercial Buildings in the following way:
•Commercial
•Industrial
•Institutional
•Complex residential - ✔️✔️Commercial- mixed use buildings, retail,
office/warehouses, multi/tenant buildings
, Industrial- used for manufacturing/distribution centers , foundries, petrochemical plants,
water/sewage treatment facilities
Institutional- public use facilities, schools, colleges, hospitals, libraries, offices
Complex residential- condos, apartments, hotels, private mansions
Decisions made following the initial inspection includes, but are not necessarily limited

hazards and perform risk assessments
Preliminary determination of category of water
Establish dry standards
Determine drying goals
Identify need for any specialized experts
If the restorer has been informed by the customer that water did not affect adjacent
areas or floors, the restorer is safe-to assume that. True or False - ✔️✔️False, check
all adjacent areas
Satisfactory completion of a job or phase of a job should be obtained when________ -
✔️✔️Returning the building or a portion of it to the client
According to the current IICRC S500 Standard, a restorer should establish an initial
dehumidification capacity needed on a project, but should be modified after that based
on___________________________________ - ✔️✔️Subsequent or following days
psychrometric readings
Some of the other project factors that may need to be considered in adjusting the
dehumidification requirement can be (describe at least three) - ✔️✔️An agreed upon
deadline to complete the job
Power is known to be less than adequate to serve the indicated inventory of equipment
The building will be occupied during the drying process, potentially causing equipment
cut off, frequent opening of doors, higher moisture load
A schedule imposed by client
Required pressure differential to achieve contaminant control
Sizing desiccant dehumidification in larger commercial drying applications typically
begins with determining a targeted________________________ - ✔️✔️Air change per
