CLEANING AGENTS AND GREEN ALTERNATIVES
TRADITIONAL CLEANING PRODUCTS
Many indoor air quality complaints arise from inadequate housekeeping that fails to remove dirt and dust. Schools should be cleaned frequently, thoroughly and effectively. However, the industrial strength cleaning products and room deodorizers that some schools use actually add to indoor air pollution. These products can produce odors and emit a variety of chemicals. Conventional cleaning products may contain toxic ingredients that can not only cause rashes, headaches, nausea and dizziness, but can also lead to long-term health problems such as asthma, cancer and lung disease. Many are known to affect the respiratory system, central nervous system, reproduction, development, kidney and liver.
Exposure to traditional cleaning products poses a serious risk to children for a number of reasons. Children’s organ systems are still developing. Cleansers produce aerosols, vapors, fumes or dusts that may be inhaled or come in contact with eye tissue. Residues from chemicals can come into contact with skin and either burn skin tissue or get absorbed through the skin and be carried to body organs. Many of their behaviors expose children to threats from toxic chemicals. They often play on the floor or ground and come in contact with chemical residues. They then either put their hands in their mouth or don’t wash hands before eating and accidentally eat chemicals through hand-to-mouth contact.
Toxic cleaning products used in schools also present a significant threat to custodial staff who handle them directly. One custodian uses an average 194 pounds of chemicals a year, 25% of which are hazardous substances. NIOSH reports that 12% of work related asthma is the result of exposure to cleaning products. Every year 6% of custodians are injured by a chemical exposure and 20% of these injuries are serious burns to the eyes or skin and12% are the result of chemical fumes.
Schools should look for safer alternatives to traditional cleaning chemicals. If conventional products are being used, the following practices will help to protect school occupants:
- Have a Material Safety Data Sheet (MSDS) for any liquid or chemical used
- Provide training for all staff who might be exposed to hazardous products
- Have a hazardous response plan is in place for dealing with chemical spills and accidents
- Be sure that all products are labeled properly and that label instructions on proper usage, dilution and disposal are carefully followed.
- Ventilate work areas
- Do not use hazardous chemicals in mechanical rooms or HVAC plenums.
- Wear protective equipment ( goggles, respirators and aprons)
- Store hazardous products in high locked cabinets and in original containers. A local exhaust system should be permanently installed where hazardous products are stored. To prevent chemical off-gassing, be sure that product lids are tightly secured when not in use.
GREEN ALTERNATIVES - ENVIRONMENTALLY PREFERABLE CLEANING PRODUCTS
According to the CT Department of Administrative Services website, “Environmentally Preferable Products are products or services that have a lesser or reduced effect on human health and the environment when compared with competing products or services that serve the same purpose. ….. By purchasing products with fewer toxic ingredients, we minimize the hazardous impacts of those products during manufacture and reduce the damage caused through accidental spills and when disposed. We also reduce the risk to workers handling the products, and the risks posed to building occupants.” The EPA’s website lists the benefits of Environmentally Preferable Purchasing as 1) Improved ability to meet existing environmental goals, 2) Improved worker safety and health, 3) Reduced liabilities and 4) Reduced health and disposal costs.
Use of safer alternatives and green/environmentally preferable cleaning products (EPP) in schools can help reduce the health risks to students and staff associated with traditional cleaning products Third party certification of institutional cleaners is important to ensure product quality. Common third-party programs are: EPA’s Design for the Environment, Green Seal (GS) in the US and Environmental Choice (EC) in Canada. EPP products should contain no known carcinogens and no or low VOCs. They should be biodegradable, neutral pH , non-flammable, non-reactive, non-irritating to eyes and skin and free of fragrances and dyes. Cleaners should be multi-purpose, not packaged in aerosol/spray cans and have dispensing systems that minimize exposure to concentrated solutions
When deciding which safer alternatives to use, schools should:
- Use plain soap and water as cleaning agents when possible
- Remove dust with a HEPA vacuum or a damp cloth
- Use disinfectants only as required by state law
- Select the safest available materials that can achieve the desired result
- Review all information on product labels and MSDS sheets
- Request information from suppliers about the chemical emissions of the products being considered for purchase.
If products with strong odors or air contaminants must be used, it is best to use them early in the weekends or vacation periods to allow fumes to dissipate before the building is reoccupied. Exhaust fan should be used during application and vapors from cleaning products should be completely eliminated before air handling systems are switched to their unoccupied cycles.
Special Note:
The Connecticut School Indoor Environment Resource Team is now offering a special program on “green” cleaning, entitled Cleaning for Health. The program includes an overview of the reasons for implementing “green” cleaning, the components of a Cleaning for Health program, and technical assistance to make the switch. Contact Kenny Foscue or Joan Simpson at 860-509-7740 to find out more about this program.
Summary of CT LAW dealing with green cleaning in schools
*** NOTE: CT law only requires green cleaning products in state-owned schools, it does not apply to schools run by local or regional boards of education. ***
CT GREEN CLEANING LAW FOR STATE-OWNED SCHOOLS
(CT General Statutes Section No. 4b-15a)
- Bans the use of cleaning products that do not meet certain guidelines or environmental standards in state-owned buildings, including state schools (Green Seal Certified products only)
- Requires cleaning products to minimize potential harmful impact on human health and the environment to the maximum extent possible
- Excludes disinfectants, disinfecting cleaners, sanitizers and other antimicrobial products regulated by federal law
GREEN CLEANING IN CT PUBLIC SCHOOLS REQUESTED AND ENCOURAGED
(CT Governor M. Jodi Rell’s Executive Order #14 (April 17, 2006))
Requests and encourages municipalities and school districts to review their purchasing and use of cleaning and/or sanitizing products and urges them to procure and use products having properties that minimize potential harmful impacts to human health and the environment.
QUESTIONS & ANSWERS
Question: What are MSDS sheets?
Answer: Material Safety Data Sheets (MSDSs) are product information sheets produced by the company that manufactures or imports the product. They contain information about the ingredients in the product. MSDSs must contain the following information:
- Date the MSDS was prepared
- Name, address and phone number of the manufacturer or importer
- Hazardous ingredients list, with % of the substance in the mixture or product
- Exposure limits for individual products
- Health effects of exposure and routes of entry into the body
- Safe Handling and storage of the product
- Personal protective equipment and control methods to use to prevent exposure
- Fire and explosion hazards
- Emergency and accidental spill cleanup information
- First aid procedures to use in case of exposure
Under the US Worker Right to Know Law, school districts are required to provide custodians access to the MSDSs of all products they may be exposed to when working. School districts are also required to ensure that all cleaning and maintenance products are properly labeled, that special training for all employees who might be exposed to hazardous products is provided, and that a hazardous response plan is in place for dealing with chemical spills and accidents.
Question: Do green cleaning products cost more than traditional products?
Answer: Environmentally preferable cleaning chemicals are readily available through most manufacturers and distributors and the products themselves are generally not more expensive. There may be some initial costs for employee training and the installation of dispensing systems. There may be costs associated with the disposal of toxic cleaning chemicals currently in use.
Question: Is there more to “green cleaning” than just buying green cleaning chemicals?
Answer: A green clean approach includes both the purchase of environmentally preferable products and the use of best cleaning practices. Custodians need to be trained in the correct procedures for using the new materials. Green cleaning also means using common sense practices to reduce dirt and litter from coming into the building in the first place. For example, sidewalks and parking lots should be kept free of dirt and snow, and walk-off mats and trash cans should be placed at all school entrances.
Question: What problems have you found with cleaning supplies or practices during a school walkthrough inspection?
Answer: We found unlabeled cleaning chemicals and unapproved personal cleaning supplies in many classrooms. We also discovered that floor waxing was being done early Monday morning instead of on Friday night. Strong odors greeted students and staff when they started their week.
Our school was using two separate “green” products for two different purposes. One night custodian decided to mix the two products to get his job done faster. The next morning there was a steady stream of students and staff visiting the nurse’s office with respiratory problems. The custodian claimed the mixture didn’t bother him at all.
Respiratory Hazards and Restroom Deodorant Blocks
Why are deodorant blocks hazardous?
Some restroom and urinal deodorant blocks contain paradichlorobenzene (p-dichlorobenzene, 1,4-
dichlorobenzene, or “para”), a respiratory irritant that can trigger an asthma attack in a person who already
has asthma. Exposure to paradichlorobenzene occurs primarily indoors, from products such as deodorant
blocks and mothballs.1 Para persists in the environment, and the National Toxicology Program reports that
it is reasonably anticipated to be a human carcinogen.2 Many other restroom and urinal deodorizing blocks
that do not contain paradichlorobenzene contain ammonium quaternary compounds (“quats”), disinfectants
that are known to cause asthma when used in cleaners.3
What alternatives exist?
Deodorant blocks that contain surfactants or bacterial cultures can be just as effective as para-based or
quaternary ammonium-based blocks. In addition, autoflush toilets and urinals may eliminate the need for
deodorant blocks in certain situations, while more frequent cleaning of regular toilets and urinals may
reduce the need for them.
Do alternative deodorant blocks cost more?
The para-free deodorizers that Erie County (NY) chose to use in some of its facilities cost approximately
$10 more per dozen, a minimal increase relative to the county’s overall facilities operational budget.
However, the 8-ounce enzyme-based blocks lasted almost three times longer than the para-based product.
Where can I get deodorant blocks that do not contain paradichlorobenzene or ammonium
quaternary compounds?
Many vendors supply alternative products. A few brand-name deodorant blocks that do not contain
paradichlorobenzene or ammonium quaternary compounds are listed below.

Who else is using urinal blocks without paradichlorobenzene or ammonium quaternary
compounds?
Erie County (NY) pilot-tested three alternative urinal blocks in 2001 and found two brands that were
acceptable. The county now has only non-para blocks on contract and estimates that using these
alternative products prevents 1 ton of paradichlorobenzene emissions per year. (For a case study, see
http://www.informinc.org/fserie.pdf.) Other jurisdictions, including San Francisco and the State of New York
Department of Corrections, have also stopped using paradichlorobenzene blocks.
What about the urinal screens that come with the blocks?
Because of the environmental problems associated with polyvinyl chloride (PVC), INFORM recommends
buying urinal screens that are not made from PVC. Screens made of polyethylene and other plastics are
widely available.
