Available in almost all new lawn and garden equipment. If the relative humidity near the middle of a room is fairly low (e.g., 30 percent at 70° F), mold or mildew problems in the room are likely to be surface temperature dominated. Poorly functioning ventilation systems that provide inadequate quantities of outside air; Poor acoustics due to loud heating and cooling systems; Chemical off-gassing from pressed wood and other high-emission materials, which may be of greater concern because of rapid occupancy and poor ventilation after construction; Site pollution from nearby parking lots or loading areas. (June 1991)* Prepared by the National Environmental Health Association (NEHA), U.S. Public Health Service and U.S. EPA. Even when people smoke outside, secondhand smoke may enter the school through the ventilation system, windows and doors.

As air moves from supply outlets to return inlets, for example, it is diverted or obstructed by walls and furnishings, and redirected by openings that provide pathways for air movement. When districts specify a portable design, they typically create a term contract that other districts can use to purchase the same (or slightly different) design. Symptoms may mimic influenza and include: At high concentrations CO exposure can be FATAL. To carry out its information dissemination responsibilities, EPA's Indoor Air Division has produced a number of publications which have been distributed to a wide range of audiences and will launch an indoor air quality information clearinghouse in 1992. Air pressure differences created by these forces move airborne pollutants from areas of higher pressure to areas of lower pressure through any available openings in: For example, as long as the opening to an inflated balloon is kept shut, no air will flow. Indoor Air Quality (IAQ) refers to the state of the air within a space. Exposure to inhalable particles can affect both your lungs … Fact Sheet: Mold in Schools. Never mix products, such as household cleaners, unless directed to do so on the label. Studies indicate that students can be exposed to high levels of diesel exhaust when they are inside school buses, near idling school buses and even inside schools (due to exhaust penetration from idling buses).

See EPA's Asthma page. VOCs cause eye, nose and throat irritation, headaches, nausea, and can damage the liver, kidney, and central nervous system. Asthma episodes are most likely to occur the day after outdoor pollution levels are high. Learning About Radon: A Part of Nature. The problem of diesel fuel gelling in cold weather has been resolved by the creation of winter blends of fuel and fuel additives that better withstand colder temperatures. To decrease humidity, open the windows if it is not humid outdoors. Resolve as many problems as possible and note any problems that you intend to fix later. See Section 6. DOHS staff are available to assist in evaluating ductwork. EPA has classified secondhand smoke as a known cause of cancer in humans (Group A carcinogen).

If the excess water or moisture problem is not fixed, mold will most probably grow again, even if the area was completely cleaned. Nonetheless, your efforts may not have noticeably reduced the concentration of the contaminant or improved ventilation rates or efficiency. Building codes have been developed to promote good construction practices and prevent health and safety hazards. Once you identify the likely cause of the IAQ problem, or the solution is readily apparent, refer to Section 6: "Solving IAQ Problems" for potential courses of action. (Maintaining a room at too low a temperature can have the same effect as a set-back thermostat.) Answers commonly asked questions about the effect of combustion appliances e.g., Fight Lead Poisoning with a Healthy Diet. If the Action Kit or its contents are reproduced or modified, EPA would appreciate knowing how it is used.

Some pollutants cause health problems such as sore eyes, burning in the nose and throat, headaches, or fatigue. Other than for lead and asbestos remediation, there are no Federal regulations covering professional services in the general field of indoor air quality, although some disciplines (e.g., engineers, industrial hygienists) whose practitioners work with IAQ problems have licensing and certification requirements. Goals are to meet and maintain air quality standards, limit emissions of hazardous and toxic pollutants, and inform the public about current air conditions. Our mission is to identify and study public health problems related to indoor environments, support the development of solutions to those problems, and ultimately promote healthy indoor environments in California. Pesticides: Uses, Effects and Alternatives to Pesticides in Schools. During an asthma episode, the airways in the lungs narrow, making breathing difficult. Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma and other respiratory complaints. For example, lawn and garden equipment should be maintained regularly according to manufacturer guidelines to prevent problems that decrease efficiency and increase emissions. EPA's Indoor Environments Program offers several IAQ tools and programs designed to protect occupant health, promote comfort and productivity, and enhance the durability of structures. The US Environmental Protection Agency (EPA) Science Advisory Board rated indoor air pollutants, excepting radon, as the third highest of 30 environmental risks, well ahead, of sixth ranked occupational exposures to chemicals. asbestos).
