Introduction to Molds
Molds
produce tiny spores to reproduce. Mold spores waft through the indoor
and outdoor air continually. When mold spores land on a damp spot
indoors, they may begin growing and digesting whatever they are growing
on in order to survive. There are molds that can grow on wood, paper,
carpet, and foods. When excessive moisture or water accumulates
indoors, mold growth will often occur, particularly if the moisture
problem remains undiscovered or un-addressed. There is no practical way
to eliminate all mold and mold spores in the indoor environment; the
way to control indoor mold growth is to control moisture.
Ten Things You Should Know About Mold
- Potential
health effects and symptoms associated with mold exposures include
allergic reactions, asthma, and other respiratory complaints.
- There
is no practical way to eliminate all mold and mold spores in the indoor
environment; the way to control indoor mold growth is to control
moisture.
- If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
- Fix the source of the water problem or leak to prevent mold growth.
- Reduce
indoor humidity (to 30-60% ) to decrease mold growth by: venting
bathrooms, dryers, and other moisture-generating sources to the
outside; using air conditioners and de-humidifiers; increasing
ventilation; and using exhaust fans whenever cooking, dishwashing, and
cleaning.
- Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.
- Clean
mold off hard surfaces with water and detergent, and dry completely.
Absorbent materials such as ceiling tiles, that are moldy, may need to
be replaced.
- Prevent condensation: Reduce the potential
for condensation on cold surfaces (i.e., windows, piping, exterior
walls, roof, or floors) by adding insulation.
- In areas
where there is a perpetual moisture problem, do not install carpeting
(i.e., by drinking fountains, by classroom sinks, or on concrete floors
with leaks or frequent condensation).
- Molds can be found
almost anywhere; they can grow on virtually any substance, providing
moisture is present. There are molds that can grow on wood, paper,
carpet, and foods.
How do molds affect people?
Some
people are sensitive to molds. For these people, exposure to molds can
cause symptoms such as nasal stuffiness, eye irritation, wheezing, or
skin irritation. Some people, such as those with serious allergies to
molds, may have more severe reactions. Severe reactions may occur among
workers exposed to large amounts of molds in occupational settings,
such as farmers working around moldy hay. Severe reactions may include
fever and shortness of breath. Some people with chronic lung illnesses,
such as obstructive lung disease, may develop mold infections in their
lungs.
Molds can trigger asthma episodes in sensitive
individuals with asthma. People with asthma should avoid contact with
or exposure to molds.
Mold Cleanup
The
most important element in stopping mold from occurring is moisture
control. In order to eliminate and prevent mold you must dry water
damaged areas and items within 24-48 hours to prevent mold growth. If
mold is a problem in your home, the mold must be cleaned and all excess
water or moisture eliminated. In order to prevent recurrences, you must
fix all leaky plumbing or other sources of water. Mold can be washed
off hard surfaces with strong detergent and water, and then dried
completely. Absorbent materials (such as ceiling tiles & carpet)
that have become moldy will most likely need replacement.
Mold Remediation
Safety Tips While Investigating and Evaluating Mold and Moisture Problems
- Do not touch mold or moldy items with bare hands.
- Do not get mold or mold spores in your eyes.
- Do not breathe in mold or mold spores.
Assess
the size of the mold and/or moisture problem and the type of damaged
materials before planning the remediation work. Select a remediation
manager for medium or large jobs (or small jobs requiring more than one
person). The remediation plan should include steps to fix the water or
moisture problem, or the problem may reoccur.
Mold Removal
In
most cases, you will want to hire a Certified Mold Contractor or
Certified Mold Remediator. Dangers from airborne mold are serious, and
hiring a professsional is the best step to completely and safely remove
mold problems, contamination, and infestation from your home,
condominium, rental apartments, office, warehouse, retail store or
other real estate buildings.
Effective and safe mold removal, mold remediation, mold mitigation, and mold abatement means:
- The mold MUST be contained to the area it is in and not allowed to spread
- The mold MUST be killed with biocides
- The dead mold MUST be removed from the infected areas
- The infected areas MUST be treated to protect against future mold infestations
