Indoor Air Quality / Mechanical Hygiene

How Does An Indoor Air Problem Start?

Pathogenic Microbes
The following organisms have been shown to have adverse effects to human health.

Stachybotras Chartarum

Toxic fungus that inhabits wet cellulose containing material, such as gypsum board. Stachybotras contains a toxin that is detrimental to human health, that may be present even after the organism has died.

Aspergillis

Prolific fungus that grows in a wide temperature range. Inhalation causes opportunistic infections in immune deficient people. Can be a serious problem in health care facilities.

Cladisporium

Typically found in fibrous/fiberglass ductwork insulation and unserviced fan and air handler components.

 

 

Today's indoor climate control systems are complex machines requiring a great deal of monitoring and maintenance. When left unserviced HVAC systems generate condensate which results in standing water. When this water is left in contact with cellulose components it fosters an ideal breeding ground for molds, funguses, and pathogenic bacteria.

Increasing evidence is pointing towards the critical relationship between these microorganisms and human health. Indoor microbial contamination has been defined as a leading causative factor in Sick Building Syndrome (SNS).

Contaminated indoor air, in the business office environment, can result in reduced employee productivity, increased operational costs, as well as a greater potential exposure to litigation. Over extended periods of time, airborne contaminants have proven to have serious negative effects on human health.

ACTION REMEDIATION utilizes state of the art HEPA equipped ventilation equipment to remedy the source of indoor contaminants. Once the source of the problem has been removed, ACTION can initiate a cost effective service program that can significantly reduce the possibility of reoccurrence.

MICROBIAL REMEDIATION
       
A Case History Using Selikoff Protocol

  Microbial contamination was thriving behind what appeared to be a normal finished wall
  Large sections of mold existed on the walls underneath the vinyl wall covering
Microbial growth in buildings is known to cause or exacerbate allergic type symptoms (such as wheezing, chest-tightness, shortness of breath), especially in persons with a history of respiratory disease. In this specific case, an office space area located in the basement of a commercial office building had developed an indoor air quality problem as a result of moisture intrusion to the open space behind the finished wall sections.

As indicated in the illustration, the growth of multiple species of molds was prolific, causing respiratory ailments to the inhabitants of the space, despite the growth not being visible from the finished side of the wall.

Project Objective
Eliminate fungal growth and remediation of remaining surfaces using Selikoff Protocol.
