EPA Programs
What Is Our Goal?i.e. the commercial!
EPA/Federal/State Programs should supportSchools in their primaryMission, which is educatingKids!
Environmental (& health &Safety) issues must be viewedIn context with each other
EPA & States & PartnersProvide tools (training, technicalSupport, guidance) to schools

And now….
More Information on Chemicals!

Why Be Concerned About Chemical Management?
Health hazards: immediate & long-term
Safety hazards: stability of shelves, storage methods and incompatibility
Environmental harm: groundwater, discharges to streams/rivers, air pollution
Hidden costs/liabilities: lawsuits, fines, Paperwork/fees, insurance premiums, etc
![Page 6: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/6.jpg)
Types of Chemicals Posing Hazards in Schools
• Extremely flammable
• Corrosive
• Poisonous
• Carcinogenic
• ANYTHING STORED IMPROPERLY
• Reactive: explosive, heat generating, fume/vapor generating
• Unknowns
![Page 7: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/7.jpg)
Examples : Poor Storage Practices
• Water reactives near / under sink• Heavy containers on high shelves• Corrosives on (corroded) metal
shelves• Flammables stored on wood• Alphabetical storage (incompatible?)• Unlabelled/”mystery” contents• Chemicals next to food
![Page 8: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/8.jpg)
Why are there problems with chemical management in
schools?
• Lack of awareness
• Lack of environmental management system
• Lack of “somebody in charge” (add-on duty)
• Discount warehouse store effect
• Spend it or lose it monies
![Page 9: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/9.jpg)
Why are there chemical management problems in
schools? (contd)• Stockpiles from the 1950’s – era of
Sputnik and technology race
• Often little communication across Academic, Administrative, & Facilities departments
• Facilities often not built for handling chemicals (ventilation, storage problems)

What IS it????
![Page 22: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/22.jpg)
You’re Probably Already Convinced That the Situation
Requires Action
• Timeframe– Short term– Longer term
• Actors
• Actions
![Page 23: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/23.jpg)
Short Term Actions• Learn about chemical hazards
today’s presentation is just the first step
• May be requirements at various levels– Federal (e.g. OSHA HazCom, Chem
RTK)– State– Local (e.g. building or fire code)– District
![Page 24: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/24.jpg)
Short Term Actions• Build awareness in
– Administration– Business Officials– Purchasing– Facilities / Maintenance
• Elements to build awareness of – Issue is important– It needs attention– It needs funding
![Page 25: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/25.jpg)
Short Term Actions• Work with professionals to identify
hazards
• Get rid of the Stockpiles– Prescreen– Inventory– Remove chemicals
• Hazardous• Outdated• No longer needed
![Page 26: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/26.jpg)
Short Term Actions
•For inventory remaining–Obtain and Maintain Material Safety Data Sheets•Keep 1 set in lab•Keep 1 set in office
![Page 27: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/27.jpg)
Longer Term Goals
• Develop a chemical management system– Purchase– Storage, including labeling– Use, including labeling– Disposal– Emergency Planning – spills,
explosions, accidents
![Page 28: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/28.jpg)
Longer Term Goals• Use safer chemicals & less too
– Order min quantities, consistent with use
– Try to keep only 1 year’s worth stock
• Prohibit certain chemicals period(hazard potential outweighs educational potential?)
![Page 29: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/29.jpg)
e.g. IDPH “Dirty Dozen”
• Barium chloride• Benzene• Carbon disulfide• Carbon
tetrachloride• Cyanide
compounds• Formaldehyde
• Hydrofluoric acid
• Mercury & compounds
• Picric acid• Potassium metal• Sodium metal• Thermite

Longer Term Goals• Order “safer” alternatives,
packaging, dilutions, kits– Green chemistry– Microscale approaches (e.g.
spot plates instead of test tubes)
• Centralize inventory/purchasing
![Page 32: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/32.jpg)
Longer Term Goals• Develop and maintain chemical
hygiene plan for lab chemicals (at least)
• Chemical Hygiene Plan identifies– Responsibilities
• Administration• Teachers• Students
– Basic rules and procedures • Safety• Handling of hazardous materials• Spill procedures • Waste procedures• Training
![Page 33: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/33.jpg)
Longer Term Goals• Chemical hygiene plans intended
for the protection of EMPLOYEES
• Model plan (IL) at http://www.isbe.net/ils/science/pdf/science_safety.pdf
• Inform school or district chemical hygiene plan
![Page 34: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/34.jpg)
Longer Term Goals• Regularly budget for removals
(Cradle to grave)
• Address chemical issues in context with other environmental concerns
![Page 35: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/35.jpg)
Need To See “The Big Picture”
• Chemical management can affect – Safety– Health – Indoor Air Quality
• Chemical mismanagement can affect– Drinking Water Quality– Stormwater Quality
• Environmental stewardship
![Page 36: No More Methyl Something](https://reader035.vdocuments.site/reader035/viewer/2022062220/5558b6d9d8b42a7e298b4c79/html5/thumbnails/36.jpg)
Need To See “The Big Picture”
• Look At Chemical Management as part of bigger set of EHS Issues (e.g.)– Poor IAQ – Pests /pesticide use– Mold– Deferral of maintenance– Funding
• Environmental Management Systems (EMS) - puts issues in context & addresses continuous improvement

Special Case : Mercury• Schools should get rid of mercury
– Bulk– Equipment
• Any Hg spill greater than 1 fever thermometer is a LARGE spill – get help!
• Any Hg spill greater than 2 TBS must be reported Any time one pound or more of mercury is released to the environment, it is mandatory to call the National Response Center (NRC). The NRC hotline operates 24 hours a day, 7 days a week. Call (800) 424-8802. Note that because mercury is heavy, only two tablespoons of mercury weigh about one pound

In Cleaning Up Small Hg Spills
• Never use– Broom– Vacuum cleaner
• Don’t pour down drain
