When things look messy, EPA considers this a "visual clue of possible non-compliance warranting further inquiry."

Look for an area in your laboratory or room that can be designated as your waste storage area.  (More than one designated area is allowed). 

Post the EHRS waste storage area sign that contains a list of reminder procedures to designate the area(s).  (Call the Environmental Health and Radiation Safety (EHRS) Department if you need a sign).

The Griffith Hall and McNeil Science and Technology Center Central Stockrooms have these pre-printed tags available.
[Leave date field on tag blank until just before transfer to the stockrooms.]

Also, hazardous waste must be labeled with the words "hazardous waste." Therefore, use the tags.

No abbreviations or formulas are allowed.
(i.e., unacceptable: waste HCL
              required:  hazardous waste - hydrochloric acid)

No open containers are allowed anywhere (i.e., laboratory, fume hood, storage area).  Do not store waste in open beakers or flasks.  Open funnels must be removed from the bottles unless actively pouring waste. However, the sealable funnels attached to bottles are acceptable, if closed. 

Parafilm is also not an acceptable practice to seal your waste containers. 

The EPA considers an open or improperly labeled waste container a serious violation.

This will allow you to keep the collection tube in place, even if the instrument is not running.

Also, store this waste container in a tub.

If there is not a small hole in the cap, make sure the tubing is removed and then the container sealed with the cap as soon as you are no longer adding waste to the container. (Special caps with holes are available in the Griffith Hall Central Stockroom.)

Use tubs that are available from the stockrooms to keep containers of incompatibles separated. Separate the containers, but also remember to never mix incompatible wastes in one container.
e.g., separate acids from bases, separate oxidizers from flammables

Store your liquid waste containers in leak-proof plastic tubs. This is important to contain leaks or spills, to separate incompatible wastes, and especially when chemicals are stored near a drain or sink. (Tubs are available in the stockrooms.)

Never put corrosives in metal containers or ethers in clear bottles. Also, always try to store waste in plastic containers rather than glass, if compatible.

Never place these in the same container.
Volumes of hazardous waste will increase subjecting the University to increased costs and regulatory requirements. To determine if the chemical is a regulated hazardous waste, contact the EHRS Department or consult EPA regulation 40 CFR 261. You may also visit the EHRS Department's web site for the EPA hazardous waste list by clicking on the link below.

See EPA's Hazardous Waste List.

For example, procedures on how to move chemicals around campus safely. Link to Transportation of Hazardous chemicals. Also, examples of emergency procedures include spills or leaks, injuries or illnesses, fire and accidental chemical exposure.  (The EPA will conduct interviews with faculty, staff and students during their inspections of the University).

We have classroom training and web-based training modules to meet these requirements.  Laboratory Directors, Principal Investigators and Supervisors must make sure that employees and student workers in their laboratories complete required trainings and comply with these hazardous waste policies in their daily operations.

Examples of Questions that EPA/DEP Inspectors May Ask Personnel and Students (You may keep your answers very simple.):

1)  contain it, so it does not go into a drain, if possible.
2)  leave and secure area to prevent anyone from walking through or near it
3)  call Supervisor, and
4)  call EHRS and/or Public Safety.

If you have any questions regarding hazardous waste handling, storage and disposal procedures, please do not hesitate to call the EHRS Department. (X8925, X8843 or X3141)
