WRT Certification Terms SERVPRO
Safety - answer needs to be everyone's concern
Hazard Assessment - answer primary responsibility during initial inspection is
conducting a
IEP - answer Indoor Environmental Professional
Biological contamination - answer Water losses may involve
Susceptible High Risk Population - answerelderly infants convalescents
immunocompromised
Categories of Water - answerrange of biological contamination in water considering
both original source and quality after contacting materials
Category 1 - answeroriginates from sanitary water source
Category 2 - answerwater that contains significant contamination and potential to cause
discomfort or sickness if contacted or consumed
Category 3 - answerWater grossly contaminated and contain harmful agents and cause
significant reactions if contacted or consumed
Category 3 Water Loss requires - answerFull face respirator and full PPE
Lead Based Paint and Asbestos - answertwo of the most common hazardous materials
found in structures
Wet drywall on ceilings that's sagging must be - answerdrained, removed, and properly
disposed
Technicians must be - answermedically evaluated, fit tested, and trained
Don - answerRespirator, Gloves, Tyvek
Doff - answerTyvek, Respirator, Gloves
Dispose of all waste water in accordance with - answerlocal and state laws
Air temperature - answerdictates capacity of air to hold water
, Relative Humidity (RH) - answerPercent of water vapor in the air compared to maximum
amount of water vapor the air could contain
When the air temperature increases - answerRH decreases
Dew Point - answerair temperature is lowered to the point that the RH equals 100%
saturation point
Humidity Ratio (GPP) - answeractual weight of water vapor in a given amount of dry air
14 cubic feet of air weighs - answerone pound
7000 grains weighs - answerone pound
Vapor Pressure - answerforce exerted on surrounding environments due to weight of
water vapor in air
Vapor pressure is low - answerevaporation occurs easier
Evaporation - answerchanging from a liquid to a gas
Boundary Layer - answerwater evaporates the surface becomes cooler and saturated
Condensation - answerchanging from gas state to a liquid state
Condensation occurs when - answersurface temperature of material is equal or lower
than dew point temperature of air
Sublimation - answerchanging from solid state to gas state without liquid state
Infiltration - answeroutside air mass being allowed into drying chamber
Dehumidification - answerreducing water vapor content of air
Refrigerant dehumidifiers - answerConventional and Low Grain
Balanced Drying - answerachieved when rate of evaporation is equal to or slightly lower
than rate of dehumidification
Primary Damages - answercaused by source of loss
Secondary Damages - answerongoing damage most often caused by high water vapor
High Amounts of water vapor occur when - answerrate of evaporation is higher than
rate of dehumidification
