Frequently Asked
Questions
How big
a problem is IAQ in schools?
In February 1995, the US Government Accounting Office released
a report based on a survey which indicates that over half of our
schools have problems which affect indoor air quality.
A radon-related EPA investigation of 29 schools across the country
found inadequate ventilation in most of the schools.
Nearly one in five schools has at least one room with radon above
the EPA recommended action level of 4 pCi/L.
Do IAQ problems
seem to affect certain types of schools or certain locations of
the United States more than others?
All types of schools across the country have an array of indoor
air problems, but fungal problems such as mold and mildew are particularly
pronounced in the Southeast where humidity levels are high.
Why should
schools take IAQ seriously?
The quality of the indoor air can either impede or assist a school
in meeting its core mission -- educating students. ïFailure
to prevent or quickly resolve problems can: increase the potential
for long term and short term health problems; reduce productivity
for students and staff; accelerate deterioration and reduce efficiency
of heating/cooling equipment; strain relationships among school
administration, parents and staff; and create potential liability
problems.
What is
EPA doing about IAQ in schools?
IAQ Tools for Shools outreach is a top priority. The program covers
resolving and preventing IAQ problems. Its focus is on practical
and low-cost/no cost activities for all staff. Presently the outreach
program is being coordinated with six co-sponsors: ALA, AFT, ASBO,
CAPE, NEA, PTA. and includes a training video on the proper operation
and maintenance of school ventilation systems. It is produced by
the cast and crew of the popular PBS series "This Old House"
and is available from the IAQ INFO Clearinghouse. Some EPA Regional
Offices are providing workshops on IAQ Tools for Schools.
What are
EPA's basic recommendations to schools?
1.Obtain a copy of the IAQ Tools for Schools Action Kit (Kit)
2.Obtain a copy of the IAQ Tools for Schools -- Ventilation Basics
Video
3.Ensure that an adequate amount of outdoor air is being supplied
4.Test for radon
5.Separate students and staff from construction and renovation
areas
6.Reduce use of products that require ventilation during use
7.Reduce relative humidity indoors during hot and humid summers
How much
will it cost to fix IAQ in schools?
The Kit provides practical, hands-on recommendations for schools
which can be applied using in-house staff. Following this guidance
will enable schools to correct existing problems or prevent future
problems from occurring. EPA is aware of the unique environment
in which schools must function, including limited resources and
multiple demands on those resources, therefore the majority of the
activities have been designed to be either no cost or low cost.
Are there
any potentially costly fixes for schools which may be needed to
help ensure good IAQ?
Although the majority of the recommendations in the kit are either
no cost or low cost, due to the limited maintenance budget for school
buildings there are potentially two fixes which could be costly.
The first is a leaky roof, which can cause water damage inside the
building and may lead to microbial contamination (mold, fungi, bacteria).
Secondly, if the ventilation system has been allowed to deteriorate,
there may be significant costs involved in returning the system
to its original design and/or building code intent.
Is the school
I send my child to safe?
Every type of building has the potential for poor IAQ, and based
upon limited anecdotal information we know that there are IAQ problems
in schools. It is impossible to generalize. While some schools may
have minor problems, others may have more significant ones. The
Kit provides the school staff with practical steps they can take
to correct current problems and prevent future problems. Awareness
of the issues and proactive steps to assure good IAQ will go a long
way towards providing a safe and productive learning environment
for children.
What types
of schools has EPA studied?
Investigations of radon and limited measurements of IAQ in schools
have been conducted in buildings for students in grades K through
12. The schools are from a variety of regions across the country
and consist of a wide mixture of architectural styles.
Are there
statistical data available regarding IAQ in schools?
No, not from EPA. However, the GAO report (see the first question)
contains the most significant statistical data available at this
time. A recent Congressional Office of Technology Assistance report,
along with other sources, provides anecdotal information which strongly
indicates that some schools need to pay more attention to IAQ. Deferred
maintenance, which frequently occurs when schools are short of funding,
is often the culprit responsible for poor IAQ.
Will fixing
the radon problem in a school automatically fix any IAQ problems?
No. Although radon problems in schools are often remedied by increasing
the ventilation, this will not necessarily remedy an IAQ problem.
Some indoor pollutant sources are too strong for ventilation increases
to ensure good IAQ. Increasing the ventilation in areas with high
humidity or elevated outdoor air pollutants, may in fact cause a
reduction in IAQ.
Does carpet
cause IAQ problems in schools?
Carpet use in schools provides a decrease in noise, falls, and
injuries. IAQ problems can be encountered with carpet and many other
materials used indoors if the school has any type of water problem,
such as a leaky roof. If carpet remains damp, it can become a primary
site for microbial growth which frequently results in adverse health
effects. Carpet and other furnishings that become significantly
water damaged should be removed and either steam cleaned and thoroughly
dried before reinstallation, or it should be discarded.
Will specialized
training or tools be required to complete the recommended activities
in the Kit?
Nearly all of the activities can be successfully completed without
any specialized training or tools. One of the activities, the measurement
of the amount of outdoor air being supplied to indoors, requires
an airflow measurement device such as a flowhood or pitot tube.
The Kit provides a basic information on the costs and sources of
this equipment, and some cost-saving ideas such as equipment sharing.
