Approximately 80% of all aging and unwanted chemicals were located and picked up.
86% of those had potential to cause serious health effects.
109 actual pick up sites
Average disposal cost per site = $1,843.83
Most expensive = $13,685.00

Steps to Getting It Done:
CHEMIS training through RESA
Locate and identify unwanted
chemicals
Search for funding
Final contract with disposal company
Physical pick up of chemicals

Condition of the Chemicals:

Chemicals were classified...

…from unknown solids...

…and unknown liquids...

Jars of chemicals were found packed in boxes...
![Page 12: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/12.jpg)
…and leaking onto back room shelves.
![Page 13: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/13.jpg)
Some usable chemicals were transferred to new containers.
![Page 14: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/14.jpg)
Waste chemicals were packed for disposal…
![Page 15: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/15.jpg)
…and loaded into transport vehicles.
![Page 16: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/16.jpg)
When notified in advance, some instructors placed the chemicals on lab tables for easy access.
![Page 17: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/17.jpg)
Some had sorted the chemicals into family groups.
![Page 18: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/18.jpg)
Some counties and schools randomly boxed up various chemicals and stacked them in
warehouses.
![Page 19: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/19.jpg)
Gaining access to some of the containers was difficult at times.
![Page 20: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/20.jpg)
Procrastination Does Not Pay:
Poor storage and random packaging
extended chemical location and
identification by one year
Extended time worked per site by up to
two additional days each
![Page 21: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/21.jpg)
Other Nasty Snags…
Archaic chemical names
Improper labeling
Incompatibles packed together
Shortage of supplies
![Page 22: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/22.jpg)
Technical Problems Solved...
…include cleanup of potentially dangerous situations like this one, and frees up space.
![Page 23: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/23.jpg)
What It Cost
The disposal expense for this project is estimated at $225,000 to $250,000
This is disposal cost only
Actual cost cannot be estimated
At least 14 different agencies, companies and associations
All 55 counties participated
Over 200 schools
Thousands of personnel hours
![Page 24: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/24.jpg)
Safe Storage & Handling
![Page 25: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/25.jpg)
Objective
Making your routine storage and handling of lab chemicals as safe as possible.
![Page 26: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/26.jpg)
Today’s Situation:
Aging and unused hazardous chemicals which posed safety hazards have been removed.
Some lab storage areas are still unsafe due to poor storage and handling methods.
![Page 27: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/27.jpg)
How Did We Get Here?
Abundance of Chemicals Over-estimated necessary quantities Better prices for ordering in bulk Manufacturers or other businesses
donated their excess or “exotic” chemicals
No regular stockroom inventory Poor labeling or no labeling
![Page 28: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/28.jpg)
“Frequently used chemicals should be ordered in bulk.”
“Ordering in bulk is the best deal for the money.”
“Accept any donated chemicals…”
“Labs will always do the same experiments and demonstrations…”
“I’ll remember what I put in that jar.”
Common Misconceptions:
![Page 29: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/29.jpg)
Acquisition Recommendations
Order the smallest quantity possible for each chemical No discounts, but final cost is less
Never accept “left-over” or “donated” chemicals There’s no guarantee of its purity If you don’t normally use it, you probably don’t need it
Experiments and instructors can and do change Textbooks, manuals & procedures change A new instructor may not follow your teaching plan
Labels are for everyone’s information

Food jars are designed to hold food. Store hazardous lab chemicals only in containers designed to hold them.
![Page 38: 2001 School Chemical Removal](https://reader035.fdocuments.in/reader035/viewer/2022081418/56812cee550346895d91b62b/html5/thumbnails/38.jpg)

Goals Make yours an “active” project:
Aim for removal of hazardous or excess chemicals
Assure no future accumulation of excess or hazardous chemicals
Assure all personnel are adequately trained in proper safety procedures
