The federal regulations concerning hazardous waste are:
The four Hazardous
Chemicals that become hazardous waste when discarded are not necessarily dangerous chemicals. Some are considered a hazardous waste because they persist in the environment and become sources of pollution.
Corrosive chemicals: These are either very strong acids (pH less than 2.0) like hydrochloric acid glacial acetic acid or very strong bases (pH greater than 12.5) like ammonium hydroxide or sodium hydroxide.
Reactive chemicals: These chemicals are unstable and, under certain conditions, may spontaneously and violently react with air or water to generate a toxic, flammable or explosive gas. Examples include sodium cyanide and elemental potassium.
Toxic chemicals (TCLP)
8 Heavy Metals
SilverWhich chemicals are on the TCLP list?
12 Organic Solvents
Examples of TCLP waste includes high performance liquid chromatography waste, parts washers, organic extractions, atomic absorption spectrophotometry waste, gas chromatography injection vials, photo development, etc.
Do not discard photo fixer down the drain!
The chemicals on these four lists have been identified by EPA as being hazardous waste if discarded.
Specifically named chemicals:
These lists specifically identify chemicals. U-List chemicals are hazardous while P-List chemicals are acutely hazardous.
When these chemicals are discarded they become hazardous waste. Reasons for discarding these listed chemicals:
Failure to follow any of the rules can result in fines for your department.
Accurate and complete label information is critical to provide safety, assist with disposal, and prevent inspection noncompliance. Remember, any liquid, solid, or gas present in an unlabeled container is unsafe and is a violation.
Label everything as you work. Further solutions, dilutions, buffers, reagents prepared from original stocks and used for experiments or storage should also be labeled, dated, and identified as work progresses at the bench, in laboratories, or workshop areas.
Place each hazardous waste storage container at or near the point of waste generation.
* to prevent contamination,
* to prevent evaporation,
* and to prevent spills.
* Bottles break and spills occur. To prevent a spill from creating havoc, put the bottle in a tray or pan for secondary containment.
All open containers – each carries a separate fine
Spent fluorescent lamps stored and forgotten in attic - violation
So they won’t become hazardous waste.
For example: If a solvent that has a flashpoint of 100ºF can be substituted by a chemical that has a flashpoint >140º F, the waste will no longer be considered hazardous waste.
There is no need for stocking large quantities. Today small amounts at reasonable prices can be shipped within 24 hours.
These techniques use small amounts of chemicals.
Acids and bases can be safely sink disposed if the pH is between 5 and 9, and if there are no other characteristics that define the product as hazardous waste.
Re-use of the solvent will lead to significant reduction in waste.
Proper Chemical Storage
Any damaged, broken, or non-working equipment, instruments, or furniture that is not worth repairing is considered waste and should be marked as such and discarded or recycled.
Just make sure you submit a DA 110, Disposition of Property Form.
Improper management produces penalties, these are all wrong…
