Regulatory Compliance Integrated Pest Management Indoor Air Quality

What Is IPM? (definition)An effective and environmentally

sensitive approach to pest management that relies on a combination of common sense practices.

A strategy that focuses on long-term prevention or suppression of pest populations using a combination of tactics that minimize the effect of control activities on human health and the health of other non-target organisms.

Indoor Air Quality How does Indoor Air Quality effect quality

education According to the EPA Tools for Schools

Twenty percent of the U.S. population, nearly 55 millions people, spend their days in elementary and secondary schools. In the mid-1990’s, studies show that 1 in 5 of our nations 110,000 schools reported ventilation- which impacts indoors air quality-as unsatisfactory. Students are at greater risk because of the hours spent in school facilities and because children are especially susceptible to pollutants.

Construction Practice

“ In the construction of buildings, whether for public purposes or as dwellings, care should be taken to provide good ventilation. Neglect of proper ventilation is responsible for much of the drowsiness and dullness that makes teachers work toilsome. Health Reformer, 1871

Indoor Air Quality Facts

Why is IAQ important? Americans spend about 90% of their day indoors, in classrooms, and at

home.Pollution indoors is two to five times- and occasionally more than 100

times higher than outdoor levels.

Fast Facts on Indoor Air Quality in Schools

• Three-quarters of schools reported needing to spend money on repairs,renovations, and modernizations to put the school’s onsite buildings in overall good condition. Source Department of Education National Center for Education Statistics. “Conditions of America’s Public School Facilities” 1999 Report

• The average age of public school buildings is 42 years old. School buildings begin rapid deterioration after 40 years if not properly maintained. Source U.S. DOE 1998 Report.

Why is IAQ important? Asthma

Asthma afflicts about 20 million Americans, including 6.3 millions children. Since 1980, the biggest growth in asthma cases has been in children under five. In 2000 there were nearly 2 million emergency room visits and nearly half a million hospitalizations due to asthma, at a cost of almost 2 billion, and causing 14 million school days missed each year.

Comfort Factors Comfort factors: New ASHAE Standards

62.1 have modified the standard of Humidity with ASHAE Standard 62. The old standard for humidity was 30% to 60%. The new standard drops the lower end for humidity and raises the upper end from 60% to 65%. The upper limit in humidity contains a test point for humidity control, rather than an operation limit. Source Esmagazine.com

Causes of poor IAQ HVAC: The main purpose of an HVAC system are to

maintain good indoor air quality and provide thermal comfort,two key requirements for high performing schools.

Construction Practices: Poor job-site construction can frustrate even the best design by allowing moisture and other contaminates to become potential long term problems

Operations and Maintenance: Effective maintenance and operations procedures are fundamentally important to sustaining the performance of all buildings systems. Student health and productivity can suffer when building systems fail to operate properly.

Additional causes of poor IAQ Reduced ventilation. ASHRAE Standard 62-1989 states that

ventilation for classroom space can be obtained one of two ways. Either the standard of 15 cfm of air per student in the occupied space. Or using ventilation by demand by using the CO2 levels as a set point. The set point is 700 ppm above outside CO2 levels. Normal outside CO2 levels are 400 to 500 ppm. Source ASHRAE Standard 62. Ensuring that adequate air ventilation levels are maintained will go a long way in good IAQ.

Building materials and furnishing Water intrusion –mold growth. Moisture can trigger the growth

of mold that can not only damage the school facility, but can lead to health and performance problems for students and staff. Fix moisture problems and thoroughly dry wet areas within 48 hours to prevent mold growth.

Additional causes cont. Animals/ Vermin/Pests: Control animal allergens. Remove

classrooms animals from the school, if possible. Use Integrated Pest Management practices to prevent cockroach and other pest problems (e.g., store food in tightly sealed containers and place dumpsters away from the buildings. Source EPA “Managing Asthma in the School Environment”.

Pesticides- both inside and outside. Good IPM practices are crucial in ensuring good IAQ.

What can we do?

Build a proper IAQ program using the EPA’s Tools for Schools.

• Tools for Schools uses a variety of checklists and involves all of our stakeholders. This

program builds data using Occupant Checklists, ventilation checklists, and walk

through data forms.• Resources: Forms for Tools for Schools
