Schools need to manage mold and moisture: EPA

Potential health effects and safe clean-up practices

Mold exposure can trigger asthma,
allergic reactions and more problems.

As you prepare for spring’s warmer weather, consider taking some time to review your district’s policies and procedures related to mold and moisture control.

Schools should be proactive in their moisture control practices, which are the key to controlling indoor mold growth.

Molds are a major source of indoor allergens and can trigger asthma in sensitive individuals.

Even when spores are dead or unable to grow, mold can cause health effects, such as allergic reactions.

The types and severity of health effects associated with exposure to mold depend, in part, on the type of mold present and the extent of the occupants’ exposure and existing sensitivities or allergies.

Prompt and effective remediation of moisture problems is essential to minimize potential mold exposures and their potential health effects. These negative health effects can lead to increased absenteeism and reduced performance in both staff and students.

How should mold be safely cleaned?

It is essential to clean up mold as well as excess water or moisture, because moisture is the key to mold control.

If the excess water or moisture problem is not fixed, mold will most likely grow again, even if the area is completely cleaned.

Clean hard surfaces with water and detergent and dry them quickly and completely.

Absorbent materials such as ceiling tiles may have to be discarded if the mold cannot be completely removed.

To clean up mold safely and effectively, staff should wear waterproof gloves during clean up and should not touch mold or moldy items with bare hands.

Respiratory protection should also be used in most remediation situations to prevent inhalation exposure to mold.

Spring air cleaning in schools

The transition from winter to spring
can cause poor air quality in schools.

The winter months bring changes in weather conditions and building-occupant behaviors, and therefore changes to how school facilities are operated and maintained.

In addition, spring weather may bring heavy rain and possible flooding to certain parts of the country which can impact the indoor environment in schools.

It is particularly important to put in place proactive indoor air quality (IAQ) management practices to effectively manage the transition from winter to spring conditions.

Follow the tips below to help your school prepare for seasonal IAQ challenges.

Inspect and maintain ventilation systems 
During cooler weather, the heating, ventilation and air conditioning (HVAC) system may be working overtime. Good ventilation system design, operation and maintenance are critical to providing clean and healthy air in schools. Regularly inspect your ventilation system and establish a maintenance plan to provide adequate air ventilation, control odors and reduce the levels of pollutants that cause most IAQ problems inside school buildings. The Ventilation Checklist and Backgrounder offer in-depth guidance to schools for inspecting ventilation systems.

Control moisture levels to prevent mold
In many regions, the change in seasons brings a change in outdoor temperature and humidity and an increase in rain or flooding, which can lead to moisture problems and mold growth. Maintaining the relative humidity in school buildings between 30 and 60 percent will help control mold. In addition, prompt and effective remediation of moisture problems, including drying wet areas within 24 to 48 hours, is essential to prevent mold growth.

Proactively use Integrated Pest Management (IPM)
Wintertime means more time spent indoors by students and staff, and the cooler weather can bring in unwanted pests who are seeking shelter from the cold. Pest populations can be eliminated, prevented or controlled by creating inhospitable environments for pests (removing basic elements that pests need for survival) and by blocking pest access into buildings. Follow the IPM checklist to help identify potential pest problems in schools buildings.

Involve everyone
In addition to the tips above, in order to maintain healthy indoor environments during this time of year and year-round, it is critical to ensure everyone plays a part. Open communication is a key component to securing buy-in from your school community members about the importance of proactive IAQ management and sustaining these plans long-term. The Indoor Air Quality Tools for Schools: Communications Guide is a companion tool to the IAQ Tools for Schools Action Kit that outlines the benefits of implementing an IAQ management program. It also includes case studies.

The IAQ Tools for Schools is designed to help schools maintain a healthy environment in school buildings by identifying, correcting and preventing IAQ problems.

Poor indoor air quality is a serious concern in schools, as it can affect children, teachers and staff equally. Children are susceptible to the airborne chemicals, odors, gases, particles, dust, allergens, bacteria, viruses and molds and poor IAQ has been shown to lower productivity, increase absenteeism, aggravate asthma and respiratory diseases and other health concerns.
For better quality air, schools need to implement the tips above and make sure that indoor air quality is improved. Electrocorp has designed mobile yet sturdy air cleaners for schools that can remove the widest range of airborne contaminants with their activated carbon + HEPA air filter system.

Finland: Schools suffer from indoor air pollution

Classrooms may be making your kids sick

Over the past several years, countless studies have been made on dampness and moisture in buildings throughout Finland. In 2007, researchers chose 630 random houses and apartments that were built between 1950 and 1989 for their study. Of those homes, 51 percent had moisture problems; 33 percent of those had moderate to severe issues, particularly in houses. 

Many respiratory diseases, eye irritations and allergies have been directly linked to the moisture problem across the country.

The National Public Health Institute revealed in 2007 that there was a strong correlation between damp homes and the prevalence of asthma among children. Up to one in five asthma cases could be linked to water damage in the home.

A new study, made by the Trade Union of Education in Finland (OAJ,) has now discovered that moisture issues extend beyond the home. Up to two thirds of the schools and day-cares across the country have indoor air quality issues. Approximately 80 percent of the buildings in Finland, schools and day-cares included, are not sufficiently ventilated.

Water damage in some of the damp schools is so bad that recommendations have been made to tear them down, rather than try to repair them. Though poor indoor air quality in schools have been an issue for over fifteen years now, some people believe the issue is still not being handled properly. Remediation has been slow moving, leading to parents, in one town, taking matters into their own hands.

Tervajoki School in Vähäkyrö, Finland was shut down for a week while parents pulled their kids out of the school and promised to continue striking until changes were made. The school has since been relocated pending repairs or the building of a new school.

What do you think about the parents' strike? Would you do the same if  you thought your kids were at risk? Let us know!

Improving indoor air quality in schools

Apart from the home, kids spend most of their time at school. Considering the astronomical number of children with asthma today (7 million in US), it is extremely important that the quality of the air in schools is up to par.

Removing mold is the most important first step to solving indoor air pollution in schools. Many schools in North America have been shut down recently for precisely that reason. If a school is dealing with elevated moisture, however, ventilation is the first plan of action.

Electrocorp offers air cleaners that can complement remediation and ventilation efforts within schools and universities. Our units use two different types of filters to help remove harmful chemicals, gases and particles from the air: the HEPA filter (for particles) and the activated carbon filter (for chemicals and gases). An optional UV germicidal lamp will also help remove mold, bacteria and viruses, thereby resulting in better air quality for both students and staff.
