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 to
__________________________________________________________________________________
__________________________________________________________________________________
________________________ - Identify potential hazards and perform risk assessments
Preliminary determination of category of water
, Establish dry standards
Determine drying goals
Identify need for any specialized experts
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
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
