Forensic Engineering Analysis Of Building Depressurization Induced Product Re-Entry

Abstract

With The Advances In Building Materials And Practices Through The Building Expansions Of The 1980 And 90, Along With The Inherent Benefits Of These Improvements, Some Unwanted Side Effects Have Resulted As Well. Indoor Air Quality (Iaq) Issues Ranging From Mold And Dust Accumulations Have Become Both A Nuisance As Well As, In Some Instances Health Issues To Many Homeowners Who Own Houses With These Inherent Problems. One Such Chronic Building Issue Is The Result Of The Failure To Recognize The House Heating (Or Combustion) Appliance As A Ystem This Problem Is Known As Epressurization Induced Combustion Re-Entry Depressurization Induced Combustion Re-Entry Is The Re-Introduction Of Combustion Emissions Back Into A Structure As A Result Of Negative Air Pressures Developed By The Structure As Well As The Location Of The Point Of Discharge Of The Emissions From The Combustion Appliance. Combustion Appliances Can Be Anything From A Boiler, Furnace Or Fireplace And This Problem Occurs Regardless Of The Type Of Combustion Fuel Being Consumed In The Structure. This Paper Will Address The Root Causes Of Depressurization Combustion Re-Entry Using Excerpts Of Cases Investigated And Assisted In Litigation The Paper Will Also Address House And System Modifications That Can Be Performed To Reduce Or Eliminate The Effects Of Depressurization Induced Combustion Re-Entry
