F&F
MOLD:
A multi-cellular, microscopic vegetable plant which forms cobweblike masses of
branching threads from the surface of which tiny fertile threads project into the air bearing
the part of the plant from which spores develop. Mold may be of brilliant colors or black and
white, depending on the type. Molds can develop on leather, cloth, paper, etc., especially in
the presence of relatively high heat and relative humidity.
MILDEW: A growth caused by micro-organisms, whose spores, in a moist, warm
environment, become molds. They derive their food from the substance on which they
form, e.g., the materials of a book. During their growth they produce citric, gluconic, oxalic,
or other organic acids, that can damage paper, leather, cloth, etc. They also at times
produce color bodies, leading to staining which is difficult to remove.
FUNGI: A large number of the spores of fungi is always present in the atmosphere, and
while paper is not a particularly suitable medium to support the growth of molds and fungi,
under favorable conditions, such as relatively high temperature and high relative humidity.
paper will support the growth of these micro-organisms, some of which have a similar
action on paper to that of dry rot fungus on wood
FOXING: Stains, specks, on paper. Machine made paper 18-19 century has high acid & iron. Factor
which controls foxing is relative humidity (R.H.). Fungoid in nature.

ANATOMY

NOT WANTED DEAD OR ALIVE!

Active mold will go dormant
& inactive mold will remain
dormant as long as it has no
moisture to “bloom”.

Active mold’s enzymes
digest organic materials
(paper, book cloth, etc.) It
weakens or destroys them.

Mold is a potential health
hazard whether active or
dormant.

Note the pink "splotch" at the bottom-center of this photo. It is
the telltale warning sign that there is a likely mold "bloom"
behind the vinyl wall covering. AVOID VINYL WALL COVERINGS!

HVAC

Adequately cool your
building, but they do little or
nothing to reduce the
quantity of water in the air
(the absolute relative
humidity). Failure to
dehumidify will often allow
relative humidities to reach
levels of 65% or higher —
well into the region where
mold growth is very likely.
17
Secure a clean, dry environment where the temperature and
humidity are as low as possible. The temperature ideally should
be below 70 degrees F. and the humidity below 50% to discourage…

HEALTH EFFECTS OF MOLD




respiratory problems and symptoms.
Mucous membrane irritation, coupled with a dry cough
and eye irritation, are common responses to continuous
exposure.
Bronchitis and chronic pulmonary disease, while typically
associated with smoking, may also be related to such
allergic reactions in long exposure.
Allergic rhinitis and asthma, particularly among those who
are constitutionally predisposed to allergies, is perhaps
one of the most severe responses to mold exposure

Effective against many molds & bacteria in a
short time
Breaks down to a simple salt ion that is found
in table salt & sea water
No toxic residue
Packets available for use in small closed areas
Ideal biocide (was used in 2001 anthrax
cleanups in Washington D.C.)

MOLD PREVENTION….



Keep books away from wall contact
to allow air-flow behind books
Minimize live-plant areas as they
increase humidity
Redirect water away from building
exterior (sprinklers, gutters, hill
landscaping)

PREVENTION
cont.
-No long-term dark areas
-Dust collection religiously
-Caution when accepting donated books
-Quickly fix plumbing leaks
-Regularly inspect collection for mold

MOLD PREVENTION



NO EXTREME CHANGES IN TEMP/HUMIDITY
AIR CONDITIONER /HEAT MAINTENANCE
USE DATA-LOGGERS IN LIBRARY
(records humidity & temperature fluctuations for long-term
analysis)
26
CONSIDERATIONS:
COST, EASE OF OPERATION, USE OF DATA
RECORDING HYGROTHERMOGRAPHS:
------use a human hair bundle to measure humidity. Circular & drum charts available to be
recorded on. Charts available for daily, weekly, or monthly cycle. Continuous monitoring.
SLING PSYCHROMETERS:
-----Has two thermometers. One has wick that is wetted with distilled water. The instrument is
swung for several minutes to get reading. Flow of air over wet wick cools the second
thermometer and the difference between the dry and wet temps. Calculates the RH.
DATALOGGERS:
---Use electronic sensors to record temp. & RH. Data can be transferred to
computer to produce customized charts that illustrate conditions over time.
