School Environmental 
Health Plan

School environments are healthier when they are kept clean and well maintained. Unsanitary conditions attract insects and vermin, and irritants and allergens found in dust and dirt can have a negative impact on student health and performance in schools. The chemicals found in some cleaning products can also cause health problems. Using green cleaning products and practices can help to avoid these health effects, improve indoor air quality, reduce the transmission of infectious diseases, and increase the lifespan of facilities. Maintaining the school facility is just as important as routine cleaning to ensure a healthy environment for children and staff. A regular inspection program can identify problems before they impact the school environment and the occupants' health.

The key to mold control is moisture control. Keeping the school environment dry is essential for maintaining a healthy school building, as well as promoting an environment conducive to learning and working. The presence of moisture within building structures stimulates the growth of molds and other biological contaminants, and damp schools provide conditions conducive for mites, roaches, and rodents, which are associated with asthma, allergies, and other respiratory diseases. Moisture and mold can also damage building infrastructure and result in costly mitigation and material replacement. Inspections, preventive maintenance, quick response to water problems, and proper cleanup are critical to prevent mold problems.

Schools need to provide a safe and healthy learning environment for children by preventing exposure to chemicals and environmental contaminants that pose health risks to them and the environment. Children spend a significant portion of their time in school and might be more vulnerable to chemical and environmental contaminant hazards than adults. A variety of hazards may be found in schools, including asbestos, lead, Poly Chlorinated Biphenyls (PCBs), radon, and mercury. Various state and federal regulations exist regarding these pollutants. Schools can regularly inspect for the presence of these hazards, and, where necessary, manage in place or remove the hazards.

Good indoor air quality can help ensure a healthier and higher performance learning environment for students and school staff, and proper maintenance of ventilation and filtration equipment can play a role in maintaining or improving the quality of the indoor air. Adequate ventilation with outdoor air is a key component for good indoor air quality in schools and classrooms, and can contribute to mitigating the effects of radon and vapor intrusion. Furthermore, well-maintained air filtration systems can help capture and remove airborne particles that can be asthma triggers, allergens, infectious or toxic to humans.

Droppings or body parts from cockroaches, rodents, and other pests can trigger asthma attacks and can cause allergic reactions. Some pests also can transmit disease. Pesticides should be used as a last resort to control pests because they contain chemicals that can be toxic to humans and the environment and may pose a risk to human health, especially when people do not follow directions on product labels or if they use products irresponsibly (e.g., using pesticides when they are not needed, using pesticides for other than their intended use, or not following recommended application rates). Young children can be especially vulnerable to pesticides because their internal organs are still developing and their exposure may be greater.

Schools and school districts performing building upgrades should ensure that the upgrades make their facilities more energy-efficient and healthier at the same time. When done properly, many energy efficiency upgrades can improve the quality of a school's indoor environment, protecting—even enhancing—indoor air quality without sacrificing energy performance. If certain energy upgrades are not done correctly, however, they can adversely impact indoor air quality and cause health concerns for children and staff. For example, increased energy efficiency in building construction, in some cases, has resulted in tighter building shells and reduced ventilation rates. In turn, reduced ventilation rates may result in increased levels of indoor pollutants.

Ground level ozone and particle pollution are the two air pollutants that pose the greatest threat to human health in the United States. Excessive idling by school buses, passenger vehicles, and delivery trucks can cause elevated levels of pollutants in and around the school. Reducing idling, retrofitting school buses, tracking the outdoor air quality index, and monitoring outdoor activities are critical elements to minimizing exposure to outdoor pollutants. Another outdoor concern is excessive exposure to UV from the sun, which can be reduced through education, tracking the UV index, and use of sun-screen.
