Disinfectant Properties
Disinfectant/Class	Use Dilution Concentration	Action	Advantages	Disadvantages
Alcohols (ethanol, isopropanal)	60% to 90%	B, V, F	Non-staining, nonirritating	Inactivated by organic matter, highly flammable
Quaternary ammonia compounds	0.4% to 1.6%	B, V, F	Inexpensive	Inactivated by organic matter, limited efficacy
Phenolics	0.4% to 0.5%	B, F, V, (T)	Inexpensive, residual	Toxic, irritant, corrosive
Iodophors	75 ppm	B, V, F, S, T	Stable, residual action	Inactivated by organic matter
Glutaraldehydes	2%	B, V, F, S**, T	Unaffected by organics, non-corrosive	Irritating vapors, expensive
Hypochlorites	� 5000 ppm free chlorine (1:10)	B, V, F, S**, T	Inexpensive	Bleaching agent, toxic, corrosive, inactivated by organic matter; removes color from many interior decor fabrics; dissolves protein fibers (e.g., wool, silk)
Hydrogen peroxide	> 3%	B, V, F, S**, T	Relatively stable	Corrosive, expensive, degrades in heat or ultraviolet light
Abbreviations: B = Bactericidal F = Fungicidal V = Virucidal * = Limited effectiveness ( ) = Not all formulations T = Tuberculocidal S = Sporicidal ** = Requires prolonged contact time		Protein Fire Disinfecting & Cleaning: Misty soot produced from a protein fire are attracted to and can infiltrate cool nooks and crannies, as well as deposit within and beneath content items. The micro-size of protein soot could result in property owners, adjusters and technicians to attempt a quick cleaning process, which could fail. The decomposition of living organisms found in animal fats is exotoxin bacteria, and can be toxic and emit foul decaying odors. For additional information on disinfecting and cleaning protein fires, visit ... Section 6.19) Protein Fires.
Properties of Classes of Environmental Disinfectants: Extracted from Suggested Guidelines for Remediation of Damage from Sewage Backflow into Buildings Environmental Protection Agency (EPA) Working Document Michael A.

Disinfecting Tip: The contaminate being treated, surface characteristics and toxic levels would determine the type of chemical (disinfectant) and chemical exposure time required to reach the desired decontamination level. Decontamination levels should be classified as: - Sterile: 100% contaminate free - Disinfected: 95% contaminate free - Sanitary: Level to which contaminate poses no health risk Read more about Disinfectants and Cleaning Chemicals in the Loss Recovery Guide with Standards, visit: Sections 3.0) Safety & Health and Section 4.0) Equipment & Materials
