IICRC: An acronym for Institute of Inspection, Cleaning and Restoration Certification

ANSI/IICRC S500: Standard of care for the industry

IEP: Indoor Environmental Professional

Drying: The process of removing moisture from materials
Dehumidification: The process of removing moisture from the air

Clean Water/CAT1: originates from a sanitary source and poses no substantial risk from dermal, ingestion, or inhalation exposure. However, it may not always remain clean after it comes into contact with other surfaces or materials..  Once clean water is left untreated for 72 hours, it is then classed at “Grey Water/CAT2”

Grey Water/CAT2: contains significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans. It may contain potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter (chemical or biological)..  Once Grey Water/CAT2 water is left untreated for 72 hours, it is then classed at “Black Water/CAT3”

Black Water/CAT3:  is grossly contaminated and may contain pathogenic, toxigenic or other harmful agents. Such water sources may carry silt, organic matter, pesticides, heavy metals, regulated materials, or toxic organic substances.

Regulated Materials: Posing potential or recognized health risks can include, but not limited to:

  • Arsenic
  • Mercury
  • Lead
  • Asbestos
  • Polychlorinated biphenyls (PCBs)
  • Pesticides
  • Fuels and/or solvents
  • Caustic chemicals
  • Radiological residues

CFM: Cubic Feet per Minute

FPM: Feet per Minute

AHAM: Association of Home Appliance Manufacturers

HEPA: High Efficiency Particle Air

Sterilize: 100% effective – to destroy or eliminate all forms of microbial life including fungi, viruses, and all forms of bacteria, and their spores

Disinfect: to kill or inactivate at least 99.9% of disease-producing microorganisms, but not necessarily their spores

Sanitize: to reduce the number of pathogenic microorganisms to a safe level as judged by public health agencies
