Chemical safety in K‑12 schools involves the responsible management of cleaning agents, laboratory chemicals, art supplies, and maintenance materials that may pose health risks if mishandled. Exposure to hazardous substances can cause respiratory irritation, neurological effects, and long‑term environmental contamination, making prevention essential for student health (EPA, 2024). Minnesota’s Department of Health provides guidance on safe storage, ventilation, and staff training to reduce exposure risks (MDH, 2024). At the federal level, the Frank R. Lautenberg Chemical Safety for the 21st Century Act—an amendment to the Toxic Substances Control Act (TSCA)—empowers the EPA to evaluate and restrict chemicals that pose unreasonable risks to human health and the environment. While not written specifically for schools, this Act underpins EPA’s Toolkit for Safe Chemical Management in K‑12 Schools and informs state programs like those of the MPCA, ensuring that school chemical inventories align with national safety standards (EPA, 2024).
A school that excels in chemical safety maintains a transparent, well‑organized, and prevention‑focused chemical management system. All chemicals are inventoried, labeled, and stored in secure, ventilated spaces, with hazardous waste properly classified and managed in accordance with MPCA and county requirements (MPCA, 2024; Dakota County, 2024). Staff receive annual training on safe handling, emergency response, and compliant disposal practices. Cleaning and disinfection routines follow NEA guidance to protect indoor air quality while maintaining sanitation. The school’s chemical management practices reflect both Minnesota Department of Health guidance and EPA standards established under the Lautenberg Chemical Safety Act, ensuring that all materials used on campus meet modern risk‑assessment criteria. The school’s green team collaborates with facilities staff to conduct routine audits, ensuring alignment with MDH and EPA best practices. Students are engaged through science‑based learning and stewardship activities that reinforce safe chemical use and environmental responsibility.
Strong chemical safety practices reduce exposure to toxic substances, improving respiratory health, reducing asthma triggers, and supporting overall student well‑being (NEA, 2024). Operationally, schools benefit from reduced liability, fewer emergency incidents, and improved compliance with EPA, MPCA, and TSCA regulations. Financially, efficient inventory control and proper waste classification reduce disposal costs and prevent fines associated with mismanagement (MPCA, 2024). Transparent communication and visible safety practices also build trust among families, staff, and the broader community, positioning the school as a leader in environmental health and sustainability.
Schools across Minnesota are already taking meaningful steps toward healthier, more sustainable learning futures! As districts document and share their work, their stories offer real examples of what’s possible—showing the strategies schools are using, the partnerships they’re building, and the progress they’re making. This growing collection highlights how schools of all sizes are strengthening their health resources, environmental practices, and planning efforts, offering inspiration and practical guidance for others ready to begin or deepen their own journey.

Select Best Practice Actions (BPAs) to work on and complete.
Review the list of actions that can be taken to shift your district or school toward BPNAME. Start by documenting the practices already being done at the school. Choose the practices that best fit the school's opportunities and other considerations.
Establish the foundation for a safe chemical management system by helping schools identify what chemicals are present, where risks exist, and which regulatory requirements apply. This phase ensures that districts develop clear policies, inventories, and response procedures aligned with EPA, MDH, and MPCA guidance to prevent chemical hazards before they occur.
A.1 Conduct Baseline Assessment
Conduct a full chemical inventory using MDH’s Chemical Safety Checklist: School Environmental Health Chemical Safety - MN Dept. of Health
A.2 Develop a District Chemical Hygiene & Safety Plan
Develop a written Chemical Hygiene Plan aligned with EPA and TSCA requirements. Resource: EPA Toolkit for Safe Chemical Management in K‑12 Schools
A.3 Identify High‑Risk Areas and Evaluate Ventilation
Identify high‑risk areas (science labs, custodial closets, art rooms) and evaluate ventilation and storage conditions to ensure they meet MDH and EPA recommendations.
A.4 Establish a Hazardous Waste Management Policy
Establish a district‑wide hazardous‑waste management policy referencing MPCA’s Hazardous Waste Identification and Management guidance to ensure proper classification, labeling, and disposal.
These actions focus on tracking progress, measuring compliance, and evaluating the effectiveness of chemical safety practices over time. By monitoring training rates, inventory reductions, and proper waste handling, schools can demonstrate continuous improvement, reduce liability, and ensure that chemical management remains aligned with state and federal expectations.
B.1 Track Chemical Use, Storage, and Disposal Digitally
Maintain a digital tracking system for chemical purchasing, storage, and disposal.
Conduct annual chemical safety audits and report findings to district leadership.
Performance Metrics to Consider:
Percentage of staff trained annually in chemical safety and emergency response.
Number of hazardous‑waste containers properly labeled and stored per MPCA standards.
Annual reduction in total chemical inventory volume.
Percentage of chemicals disposed of through county‑approved hazardous‑waste programs.
B.2 Track and Improve Performance
Using the established baseline and performance monitoring practices, track performance improvements over time relative to baseline use. Where possible, identify the relationship between actions and overall impact improvements.
B.3 Complete Performance Planning
Conduct an analysis of current performance and impacts, and set a strategic plan to transition the school over time toward bold goals for ideal performance. Identify the direct and indirect impacts, considering environmental, cost, health, and educational benefits.
B.4 Implement Vision Backcasting
Gather the green team and representatives from staff, students, the community, and resource organizations to imagine how improved chemical safety could help us reach our fully sustainable vision for the district and its schools. Make this scenario engaging with sketches or models. Engage youth.
These actions translate planning into daily practice by guiding staff on safe chemical use, storage, labeling, and disposal. These actions ensure that classrooms, labs, custodial areas, and maintenance spaces operate safely, using EPA‑recommended products, MPCA‑compliant waste procedures, and clear emergency protocols to protect students and staff from exposure.

Document the best practice actions you took in a project story, which also describes the team, partners, and process. See the Project Stories page.
You can submit one story per best practice action, or combine several actions into a single story. For example, a waste reduction project might include multiple best practice actions across different categories, such as a waste audit, a reuse and donation program, and educational resources. If you conceived of these as part of an integrated project, you can document them that way.
The annual review for this best practice includes
Confirming that Best Practice Actions are still active. (Eg, are programs still in operation and working? Are event or time-based actions repeated each year?)
Amending the documentation with any changes
Adding any lessons learned from the prior year to share with others.
To submit the annual review, send in the BP Tracker with the updated calendar year in the update column to reflect which BPAs are still active.
