For the building community if you have mold
go directly to assessment and remediation.
Hospitals are advised to follow environmental guidelines from organizations
like CDC and the Joint Commission on Accreditation of Healthcare Organizations
(JCAHO). Labeled Dust busters by the American Institute (AIA) has issued
Revised standard targeting airborne IC threats from construction. According
to AIA you must have a working relationship with infection control practitioners
and if not you better act real soon. JCAHO’s latest EC revision
(EC.3.2.1), became effective on January 1, 2002, which mandates the requirement
for you to work with Infectious Control (IC) staff and others to assess
the risk renovation, construction, and demolition projects assessing
patient safety. The updated standard complements and is a counterpart
of the American Institute of Architect’s (AIA) 20001 Guidelines
for design and Construction of Hospital and Health Care Facilities, which
was released last spring. Visit our links at the very bottom of this
page to all regulators and related compliance organizations.
Written as a minimum standard, the current design
and construction projects have already exceeded
these guidelines. The impulse; airborne mold
and fungi spores-which can be released in dust
generated by construction and renovation projects-contribute
to the deaths of at least 5,000 patients each
year. Some fungi such as Aspergillus are so deadly
that a single spore settled into the lung of
an immunocompromised patient can be fatal. Among
bone marrow transplant patients, morality rates
according to the CDC can be as high as 95% When
combined with an increase in solid organ transplants
and new chemotherapy regimens for leukemia patients,
construction-related could create dust, an even
Balancing the new guidelines the American Society
for Healthcare Engineering (ASHE) pushed for
the inclusion of epidemiologists. The clinical representation utilized in
combination with the design expertise of AIA and ASHE created a well
balanced desired result.
In accordance with the AIA guidelines, JCAHO
has more than 40 states requiring an Infection
Control Risk Assessment (ICRA) during the scheduling
and planning phases of construction and renovation
projects. JCAHO’s EC.3.21 mandates a “proactive
risk assessment” to establish what effect
a projected plan could have on air quality, infection
control, utilities, noise, vibration and emergency
The ICRA only needs to address areas anticipated
to be affected by a projected plan. And act accordingly
to the recommendations from a multidisciplinary
panel with expertise in infectious disease, infection
control, risk management, facility design, engineering,
construction, ventilation, safety and epidemiology.

OTHER PRECAUTIONS in Mold Abatement and Utilizing the MICROCON® AS Air Scrubber
Moisture trapped in wall cavities mainly from
leaky pipes or any number of other case scenarios,
moisture is the first condition that must be
present for a fungi mold spore to grow. In need
of the right temperature and a carbon based material
for a spore to feed on, the spores will then
start to multiply very quickly. A mold spore
will germinate in about four (4) hours once it
is moisturized by getting wet.
There are a documented 260 different species
of mold. Aspergillus, a species of mold competent
of maturing at body temperature, is often deadly
for persons who have become infected with invasive
aspergillus, the actual disease. Estimates
from The Centers for Disease Control and Prevention
(CDC) states that health care associated infections
affect at least two (2) million patients a
year, accountable for 90,000 deaths of which
1000 are aspergillus related.
Mold and mildew absorb the organic world. These
harmful matters include noxious organic substances
that act as irritants, allergens, immunogenic
agents, and toxic agents. They’re a disturbance
and a problem whether spores are viable or not,
their poisonous. Health effects from allergens
include rhinitis, asthma, chronic and acute sinusitis,
and hypersensitivity pneumonitis. Organic dust
toxic syndrome (ODTS) is well known in the workplace.
Exposure if long term can result in mycotoxicosis
specifically respiratory and cytotoxic/meaning
cell death. Neurologic and fatigue are related
Concerns of contractors regarding Mold & Mold
Abatement is the uneasiness over health issues
and property destruction caused by mold, which
is at an all time high. In the North, estimates
acknowledge approximately 30 percent of all city
and suburban homes have mold. Public buildings,
schools and hospitals also have high rates of
mold. Mold is the highest profile Indoor Air
Quality (IAQ) issue and mold remediation the
fastest growing IAQ service! MICROCON® AS Air Scrubber is used by contractors in this mold remediation.
Causes of Indoor Mold Growth? Mold expands intrinsically
on any organic substance or building material
comprised of wood, spectrate of any kind, wallpaper,
drywall, fabrics, ducting, insulation, carpeting,
paint, and adhesives. Mold is in the air and
when it finds a home on an indoor moist spot
with hardly any UV light, it assimilates. Thousands
of microscopic spores released into the environment
while the destructive organism damages the materials
on which they multiply. Mold and mildew are not
the same, but they both contain enzymes and spores.
Deceitful and treacherous mold, at its very early
stages, is somewhat natural and unassuming. The
enzymes being introduced to moisture and organic
matter create the decomposition process. Spores
are the manner of reproduction and the major
health dilemma. Mold and mildew exposure cause
Organic Dust Toxic Syndrome (ODTS) or Hypersensitivity
Pneumonitis (HP). An ODTS episode after a solarity
heavy lay open exposure to an allergen and can
result in permanent lung damage, whereas HP requires
repeated lay open exposures. At present
there are no federal regulations on the assessment
and/or remediation of mold, mildew or fungi in
homes, the business world or public dwellings. The
EPA is developing permissible exposure limits
and standardized sampling protocols.
Undistinguished and unremediated mold in the
indoor environments however, can be consequential
and expensive as most any environmental hazards,
if not remediated in the early stages. Hurricanes,
tornadoes, and heavy rain creating water incursions
and dampening of buildings are the primary cause
of mold. Mold can survive when the relative humidity
exceeds 60 percent and moisture (water) is present.
Stationary water, water soaked damaged materials
and wet exteriors also serve as a mold strain.
Essentially the only way to eliminate all mold
and fungi mold spores in the indoor environment
is moisture control.
Mold testing, control, remediation and preventive
maintenance can be achieved through the use of
mold abatement equipment, MICROCON® AS Air Scrubber and air purification
systems offered herein by Biological Controls.

and restoration projects
Biological Controls’ MICROCON® AS Air Scrubber
is a HEPA filtered combination air scrubber and
negative air machine utilized in mold abatement.
MICROCON® AS is a portable air scrubber for
creating negative air pressure in the demolishing,
reconstructive, construction area and disaster
projects. It is specifically designed for removal
and containment of airborne pollutants such as
mold spores and other hazardous airborne debris
generated during the remediation process. Designed
for versatility and portability, it can be utilized
as either a negative air machine or air scrubber.
During remediation activities significant amounts
of airborne particulate, mold spores, bioaerosols,
gas phase pollutants and odors are continually
generated. HEPA filtration with a high CFM capacity.
Designed utilizing a recessed control panel with
pressure gauge, hi/off/low rocker switch, circuit
breaker, and electronic digital hour meter.
The unit can be setup to create negative pressure
by drawing air from an enclosed space using flexible
ducting. This will allow contamination to be
contained and prevent migration of pollutants
outside the pressurized area during the construction
process. As an air scrubber it is portable, compact,
lightweight, and maneuverable for an individual
to transport. Making it ideal for small volume
applications and where space restrictions exist.
The MICROCON® AS Portable Air Scrubber will provide high volume
air changes of HEPA filtered air to achieve the
required air changes per hour (ACH). For in-room
air cleaning and the removal of gas phase pollutants
the addition of a carbon cell filter is needed.
The housing is heavy duty galvanized steel with
a baked on enamel finish. Equipped with two convenient
sturdy carrying handles, which are fastened to
the top surface. A front mounted recessed panel
houses a magnehelic gauge to monitor filter performance,
a resettable digital hour meter to register usage,
an illuminated rocker switch indicates operation
and a resettable surface mounted circuit breaker.
The fan is maintenance-free and the certified
HEPA filter is a high capacity design with a
self sealing disposable ring panel pre-filter.
A carbon cell can also be added. Filter change-out
is easy and safe. Hazardous filters can be removed
safely using a bag-out disposal system. A 10" duct
collar is attached to the inlet face and air
is exhausted through a 6" x 9" duct
opening. An optional steel panel with a 10" duct
collar can be attached over the exhaust opening
for flex duct attachment.
