Biological Controls introduces
its newest ACCUSTAT™, the P2DL
Differential Pressure Room Monitor
and Data Logger. Applications include
Monitoring Negative Pressure or Positive Air Pressure in Asbestos Abatement, Lead paint Abatement, and Mold Abatement containment areas during Remediation Projects.
Asbestos, Lead Paint, and Mold are potential Killers. Mesothelioma is a rare cancer caused by Asbestos Exposure.
Asbestos Contractors performing Abatement Remediation may also be contracting for Mold and Lead Paint Abatement Remediation projects.
Respiratory exposure to airborne Lead Paint, Mold and Asbestos dust and fibers can be potentially deadly and can pose a serious health concern should exposure escalate to unsafe levels.
The Accustat Room Pressure Monitor and Data Logger performs a necessary and vital function for Asbestos Abatement Contractors, Lead Paint Abatement Contractors and Mold Abatement Contractors. The P2DL provides constant Negative or Positive Pressure Monitoring of the containment site and provides logging features to record and retain the site status records for confirmation and future reference. This assures that staff and surrounding personnel are safe and protected while the containment site is maintained in full OSHA compliance.

data. Sampling rates from once-a-second to
once-every-12 hours may be selected thereby providing data
records that may extend from 9 hours to over 2 years.
The User Software provided on a CD (also downloadable from the WEB) is compatible with most Windows OS computers including laptops
and presented with a simple icon-driven menu. This allows start-up, select units and sampling rates, query current status, stop, or reset the logging, as well as viewing the stored P2DL data in an auto-scaling X-Y graphical-format that can be named, printed or exported to
Microsoft EXCEL for custom presentations.
Just plug the provided USB cable from the P2DL faceplate to your computer and start logging. The P2DL can continue to log or suspend
logging without the computer interface once started. This allows readings to be gathered when it is not convenient to be connected to a computer. The data can then be retrieved at your convenience. Status indicators (LEDs) are provided on the P2DL to identify Logging-Active,
Suspended-Logging, Memory Full, and System Diagnostic Verification.
Measures Actual Pressure
The ACCUSTAT™ P2DL is a true pressure transducer and not an airflow meter. You get true direct accurate pressure readings regardless
of the air quality and without recalibration or inconsistencies within the measured space. Housed in a newly designed virtually indestructible lockable polycarbonate case, its weatherproof design can take all the rigors of the road. In fact, the case comes
with its own unconditional lifetime warranty. New electronic state-of-art components are housed within the lightweight (5 lb. all inclusive) compact totally self-contained enclosure. For added convenience the new P2DL has been designed to
accommodate all of its accessories so they stow neatly, safely and conveniently inside the case. Nothing loose to get lost or damaged. Makes traveling with the unit, especially on a plane far easier and more convenient.
Battery operated or 100/240VAC plug in
Being portable, extended battery life for the P2DL was a major objective. So a new NiMH
(Nickel- Metal Hydride) battery design was incorporated more than tripling the original battery life to over 48 hrs. on a single
charge. Meanwhile, a new battery status monitoring display provides up to the
second remaining power usage. Unit can also operate on plug-in
100VAC-240VAC 50/60Hz power input (international plug adapters are
included). Automobile power port option is available for on-the-road charging using a car
cigarette lighter port. New temperature compensation micro-circuits help improve reading stability between field use operations. Simple dial “zero”
calibration feature makes occasional adjustment easy yet precise.

All the data you need to know is easy to view and access and is directly at your fingertips. User friendly
display panel with operational instructions permanently mounted makes set-up, operation and pressure monitoring easy, accurate and consistent. A large LCD display and LED indicators allow the user to adjust
custom alert set points (both audible and visual.) The new P2DL provides you instantaneous readings, unparallel accuracy with incredible ease of operation.

All to be told about Mold
Mr Gary Messina, President Biological Controls
Mold (mildew), are a type of fungi along with mushrooms and yeast and therefore can be found both indoors or outdoors. Molds are part of the natural environment and number more than 100,000 species worldwide and can be found almost everywhere. Besides existing in various colors it may appear to be slimy, powdery or even furry. It is capable of growing on food, wood, fabric, carpet, wallpaper glue, sheetrock, leather, paper, ducting, insulation and most other organic materials as long as oxygen and moisture are available.
Mold is in the air everywhere. When these tiny microscopic mold spores become airborne and land on wet or moist areas indoors they begin to grow. In locations and on materials where excessive moisture accumulates, mold will generally grow if the moisture remains uncovered and or uncorrected and where there is water, high humidity or damp conditions. This would include mold contamination of building components such as ventilation systems, walls, ceilings, floors, and support structures. Ideal growing conditions are high humidity environments or under damp conditions and it will grow fastest in warm temperatures and high humidity conditions. When these conditions are ignored or when there is incorrect remediation the colony continues to grow.
If the mold is disturbed or damaged it can become airborne and then you can breathe in the microscopic spores producing cold or flu like symptoms.
Controlling the moisture in the building can minimize mold growth. Heat,
especially moist heat that results from steam leaks, may accelerate the growth
of mold. As the mold grows, it digests whatever it is growing on and will
gradually destroy it. Even if the mold cannot be seen, its presence may be
noticed by a musty, moldy, stale or earthy smell. There is usually a great
deal more mold out of sight than what is visible.
Certain people are allergic to mold. The most common symptoms of mold
exposure are allergic reaction such as, cough, congestion, runny nose, eye
irritation, or a variety of breathing and respiratory conditions including
aggravation of asthma. These conditions may abate once the mold contamination is
eliminated. More severe reactions may occur for workers exposed to mold on the
The best way to prevent mold is not to provide opportunistic growing
conditions such as water, moisture sources and high humidity. But, where mold
colonies have been established they are producing toxins that can be
harmful to humans. This would depend upon the exposure levels and the persons
immune system. Mold particles can be inhaled of mold is disturbed or damaged.
Inhalation of fungal spores or metabolites (e.g., mycotoxins and volatile
organic compounds) can lead to allergic reactions and cause toxic effects or
cause infections. Certain symptoms (allergenic, toxic or infections) will
develop in people exposed to fungi in an indoor environment depending upon
their exposure level and susceptibility and how they are genetically
predisposed. In order for there to be indoor exposure of fungal spores, metabolites
through inhalation, physical contact or ingestion the fragments must be
Many mold species that are commonly found in indoor environments such
as Aspergillus, Fusarium, Memnoniella, Penicillium, Trichoderma, and
Stachybotrys can produce potent mycotoxins and volatile organic compounds (VOC).
Mycotoxins are fungal metabolities that have been identified as toxic agents.
Stachybotrys or black mold have been associated with health issues such as
pathogenic disease, pulmonary disorders and cancer. Therefore, anyone
performing renovation or the cleaning of fungi contamination or other bioaerosol
exposure may be at risk of developing ODTS (Organic Dust Toxic Syndrome.
ODTS can occur after as little as a single substantial exposure to dust
particles contaminated with fungi to create flu-like symptoms. It is important to
prevent the reoccurrence of contamination by promptly addressing the
underlying causes such as moisture buildup and water damage. The rapid return and
spread of mold may indicate an underlying problem such as a water leak.
