Disinfectants Safety

Here’s an update on disinfectant use in schools from our colleagues over at the Cornell Pesticide Management Education Program (PMEP). Thank you to Mary Centrella, PMEP Director and Educator, for putting it together.

As more people become vaccinated and things begin to open again, it is essential that we continue to use disinfectants correctly.Man wearing a mask, goggles, and rubber gloves wiping a table with a white cloth

Before using a disinfectant:

Assess whether it is necessary. Could soap and water be just as effective? Is the surface you are disinfectant high risk (i.e., used frequently by many people)? Be aware that recent information from the CDC shows that the risk of transmission of SARS-CoV-2 (the virus that causes COVID-19) on surfaces is considered low.

AIR QUALITY: Pest Management, when pests are too small to see

A recent EPA nationwide webinar, What Schools Need to Know: Practices and Principles for Healthy IAQ and Reducing the Spread of Viruses, focused on indoor air quality in school settings. Air quality was important before the current pandemic but is now central to the back-to-school issue.  For today’s post we’d like to share some EPA and NYS Department of Environmental Conservation resources. Some highlights: airborne disease is not the only issue. Proper surface cleaning and air filtering must be addressed. Products used to kill virus organisms are not just ‘disinfectants’, but pesticides, so their labeled directions must be followed. School buildings across the country vary widely in age, size, and management budget, making indoor air quality an important subject long before SARS Covid-19.

Indoor Air Quality has never been so important. In addition to its usual IAQ resources, EPA has created a specific Covid-19 webpage.

The Label is the Law. Read the label on very common containers of disinfectant wipes!

The major takeaway from this webinar’s experts? Using a combination of tactics is crucial to success.

  • Social distancing helps because aerosol spread (coughing, sneezing) travels farther than you’d expect. Not only in the air, but particles linger on clothing and items.
  • Masks reduce the exhalation of virus, therefore reducing what’s in the air.
  • Surface cleaning of high-touch areas. Under optimum conditions, SARS CoV-2 virus can last up to three days on plastic surfaces. There are plenty of surfaces in public buildings. These FOMITES (inanimate, contaminated objects capable of transfer microbes to new hosts) are high-touch areas such as desktops, door handles, faucets, and electronic devices. Always consult a trusted list of disinfecting products and read the label. How the product is applied is just as important. Foggers generally do not leave surfaces wet long enough (20 mins is optimum) to kill virus. CLEANING cloths should not be reused from site to site. Use clean, sterile cloths for cleaning so you are not moving microbes from place to place instead of destroying them. NOTE:  while the CDC has a list of effective disinfectants, we recommend that you PLEASE CHOOSE from this list compiled specifically for use in New York State: https://www.dec.ny.gov/docs/materials_minerals_pdf/covid19.pdf
  • Hand washing- often and done with care. Emphasize this after toilet use. (This virus also spreads through feces.)
  • Air movement. This is not just the use of a fan. Fans recycle the same air around the room. Air movement must include dilution of indoor air with outdoor air as much as possible before, during, and after rooms are occupied. The addition of air filters (properly maintained) such as HEPA filters is highly suggested. HEPA means ‘high efficiency particulate air’ filters. Filtration reduces but can not eliminate airborne particulates.

Air quality depends on more than circulation and filtration, but on proper use of disinfectants. Improper use often induces asthma, and causes health problems. Always read the label.

We remind you that care should be taken with cleaning products used in homes and businesses, as well as schools. Fraudulent claims and risky products are out there. Visit the ABCS of School IPM blog post for more information.

Reporting Pesticide Regulations Nationwide

Cover of American Entom summer 2014

The most recent issue of American Entomologist (Volume 60, Number 2) contains an interesting article authored by 11 top professionals concerned with the safety of  pest management practices. One of the authors is our own Lynn Braband who leads  the NYS Integrated Pest Management Program’s SCHOOL IPM group.

The article, Regulating Pesticide Use in United States Schools, is worth a read for its non-political, practical insight into what is going on nationally in schools.

The first law to regulate pesticide use in schools was passed in 1991 in Texas. Since that time, 39 states have enacted legislation and policies to regulate the use of pesticides including changes to how pesticides are applied, record-keeping, pesticide-free zones, pre-notification and posting when pesticides are applied, limitations on active ingredients that can be utilized, and enforcement or penalties for violations.

Numbers of states with legislation in key components of pesticide-use safety in 1998 and 2008, as well as the number of states without such legislated compliance.

Why is this important? School pests are not only annoying but they can also affect children’s health. The number one cause of student  medical absences in schools is asthma brought on by allergic reactions to exposure to cockroaches, rodents and dust mites. Simply increasing pesticide use  is not the answer, because exposure to pesticides is also linked to increased incidence of asthma.

As a parent, pesticide applicator, school safety officer, teacher or staff, or concerned citizen, it is wise to understand the larger picture of pesticide use in schools across the nation as we all work to improve pest management in your school district.

Through interviews with state officials, the article’s authors assessed the effectiveness of regulations, compared them, and inquired after officials’ wish-lists as to how to improve them.

There is no federal law addressing pesticides or Integrated Pest Management in schools, so state provisions vary widely. For example, eleven states restrict or require notification of pesticide applications to reduce drift. Nine states have buffer zones, but they vary from 300 feet to two-and-a-half miles. Quite a difference.  Does your state have these restrictions? You should know, or find out.

The New York State Neighbor Notification Law (2000) applies to all public and non-public K-12 schools (not universities) and requires all parents and staff to be notified in writing at the start of each school year that pesticides may be used periodically, and that the school is required to notify them 48 hrs in advance IF REQUESTED.  Those who request notification are placed on a registry and, unless there is an emergency application, receive notification.  In the future we will devote a blog post to the concept of ’emergency applications’,  just one small part of the larger discussion. Another post will address the incidental changes in attitudes this law created.

A lot of work went into this article and should serve as a basis to improve pesticide safety on school grounds. We appreciate their efforts and this important article.
