Colorado - Chemical Hazards: Prohibitions

Prohibitions Or Restrictions
Policy Type: 

State law requires districts to utilize environmentally-safe chemicals and/or to reduce chemical exposure in schools.


6.7.4 Insect, Rodent Control and Classroom Animals

E. The use of toxic compounds to control rodents, insects, and other pests shall be implemented only after other means have been used for control, such as the elimination of harborages, cleaning food waste, and sealing of ports of entry. All pesticides shall be used in accordance with U.S Environmental Protection Agency (EPA) registered label directions and stored in a safe manner in an area accessible only to authorized personnel. Application of EPA "restricted use pesticides" shall be performed only by a certified pesticide applicator.


6.12.3 Storage Provisions

A. Toxic or hazardous materials shall be stored in safe and appropriate containers, separated by reactive group and stored in a ventilated, locked area or appropriate cabinet. The ventilation requirement of this section may not be required where minimum quantities of such materials are stored for daily use. Toxic or hazardous materials must be stored according to the chemical manufacturer's storage temperature requirements at all times including during school holidays and breaks.

B. All containers of chemicals shall be clearly labeled with the name, original quantity of the material, and the date the material entered the school. Secondary containers and/or prepared solutions intended for storage shall be labeled with chemical name and, if applicable, the formula (including solvent), date of preparation, disposal date, and concentration.

C. Schools shall not purchase or accept donations of prohibited chemicals. These chemicals are prohibited from use and/or storage at the school unless a variance from this regulation is requested in writing by the school and approved by Department. If prohibited chemicals are found in the school, they shall be identified on the container label as "not for use" or "waste" and segregated from the chemical inventory. Unless a variance has been granted by the Department, all schools must dispose of prohibited chemicals. Prohibited chemicals are listed in Appendix A to this regulation.

D. Restricted chemicals shall be removed from the schools if alternatives can be used. If restricted chemicals are present at the school, each chemical shall be identified in the school's chemical inventory and addressed in the chemical hygiene plan as required by in Sections 6.12.1(E) and (F) of these regulations. Containers of restricted chemicals shall be labeled as such. The amount of restricted chemical shall be no more than what can be used in one school year. Restricted chemicals are listed in Appendix B of this regulation.

E. Restricted chemicals (demonstration use only) are a subclass in the restricted chemical lists that are limited to instructor demonstration. Students may not participate in the handling or preparation of restricted chemicals as part of a demonstration. If restricted chemicals (demonstration use only) are present at the school, each chemical shall be addressed in the school's written emergency plan as addressed in sections 6.13(K) and (L) of these regulations. Demonstration only chemicals are listed in Appendix B2 to this regulation.

F. All chemicals, compounds, and hazardous substances shall be inventoried by the school a minimum of once a year. The inventory shall include the name of the compound, the amount, and the year it entered the school. If restricted or prohibited chemicals are present in the school, they shall be designated as such in the chemical inventory. A copy of the inventory shall be kept in the area of use and on file in a location away from the areas where chemicals are stored. The updated inventory shall be provided to the local fire department and local emergency planning committee upon request.
