- Policy
The proper disposal of waste chemicals at the
Institute is of serious
concern, and every effort should be made to do it safely and
efficiently. The
responsibility for the identification and handling of waste
chemicals
within
the Institute necessarily rests with the individuals who have
created
the
waste.
The disposal of all hazardous chemicals down
the
drain is prohibited by the
MWRA in 360CMR10. This includes heavy metals, salts, or
organic
solvents. Any
hazardous waste must be disposed of through the Environmental
Management
Program (2-3477).
- Storage Area
The Institute has provided a storage area for
waste chemicals; the waste is
accumulated here until there is a sufficient quantity to
justify
transportation
to a disposal area. The Environmental Management Program
maintains this
storage area.
One area at the PSFC has been designated as
hazardous waste accumulation
sites where hazardous waste may be kept up to 90 days: the
yellow
flammables
cabinet near the NW21 Loading Dock. Contact
Catherine Fiore to access this site.
Chemical waste may be kept in the lab where it
is
generated in a designated
and marked "Satellite Accumulation Area". This area must be
properly
labeled, checked and inventoried weekly, and the waste must be
stored
properly. A maximum of 55 gallons of hazardous waste or 1
quart of
acutely hazardous
waste are permitted at each satellite accumulation area. Only
one
container
per waste material is allowed. Containers in the satellite
accumulation
area
must be closed unless waste is being added to the container.
Please
refer to
Appendix L. for additional information on Satellite
Accumulation Areas.
Once a
container is filled, the label must be dated and the
container must be removed from these areas within 3 days.
- Transportation
A pickup of waste chemicals may be arranged by
calling the Environmental
Management Program (Ext. 2-3477) or by filling out an
online form .
Containers generated on the south side of Albany Street (NW21
or NW20)
may be
moved to the 90 day area in NW21. Contact Catherine Fiore
(3-8440) to
arrange
this.
- Guidelines for Waste Reduction
Plan a procedure for waste disposal before you
start on a project. The
waste disposal procedures must be included in the SOP for that
chemical. Label
waste properly. It is up to each department, group, or
experimenter to
identify waste materials properly before disposal; inadvertent
mixing
of
incompatible materials could have serious consequences.
The best way to avoid cumbersome regulatory
requirements, potential exposure
to toxic chemicals, and high waste disposal costs is to
eliminate or
minimize
the use of toxic chemicals whenever possible. Protection of
the
environment
makes the disposal of large quantities of chemical and solid
wastes a
difficult problem. It is in everyone's best interest to keep
quantities
of
waste to a minimum.
The following suggestions may help:
- Order only the amount of material you need
for
your project or experiment
even if you can get twice as much for the same money.
- Use only the amount of material that is
needed
for conclusive results.
- Avoid storingexcess material, particularly
if
it is an extremely toxic
or flammable material, just because you may want it in the
future.
- Before disposing of unwanted, unopened,
uncontaminated chemicals check with
others in your department who may be able to use them.
- On termination of a research project or
completion of a thesis, all unused
chemicals to be kept by the laboratory shall be transferred
to another
project
and the supervisor receiving the chemicals shall inform the
Chemical
Hygiene
Officer (CHO) of the transfer to ensure that the chemical
inventory is
updated.
- If the unused chemicals will not be
transferred
to another project, it
is the responsibility of the person leaving or terminating
the project
to have
the unused chemicals removed for disposal. Make sure all
samples and
products
to be disposed of are properly identified, labeled with the
chemical
name(s)
and containerized. Do not leave them for others to clean up
after you.
For
more information on identifying waste see the subsequent
sections on
Identification, Unknown Waste and Paperwork on page 32-34.
- Types and Procedures
The following materials may be picked up by the
Environmental Management Program (x2-3477) for
removal to a storage area, unless otherwise specified.
Information on
appropriate containers and packaging is available from the
Environmental
Management Program. The MIT EH&S Team (Ext. 2-3477) may
also
be consulted if there is any question concerning the toxicity
or
packaging of
any toxic wastes.
- Organic solvents, Epoxies, and other
Organic Chemicals
- Organic solvents may not be put
down
the drain. The Massachusetts
Water Authority absolutely prohibits the discharge of
organic solvents
to
the sewer system. This applies to all organic solvents
whether
flammable or
nonflammable, miscible or nonmiscible with water. Place
used Organic
solvents
in suitable containers where there is no danger that
vapors or the
liquid will
escape. Containers shall be capped tightly, and
prominently labeled as
to the
types of waste they hold. Putting open containers of
solvent in
laboratory
fume hoods and allowing them to evaporate to dryness is not
an
acceptable method of disposal. Over time, such practices
may result in
the
release of tons of air contaminants into the atmosphere.
This method of
disposal is strictly prohibited at the PSFC.
- Mixtures of organic solventsthat
are
compatible and combined in one
container must be identified with an estimated proportion
in fractions
or
percentages of each solvent in the mixture. Thus, it is
best to avoid
mixing
waste solvents if possible. If guidance on compatible
chemicals is
necessary,
contact the Environmental Management Program.
- Ether that is in cans must be
transferred to glass bottles or plastic
coated bottles and diluted with water before being picked
up.
- Epoxy Resins To dispose of resins
and
hardeners, the resin and
hardener may be mixed in appropriate concentrations
recommended by the
manufacturer, allowed to cure, and be placed in the
ordinary trash
after
hardening. Empty containers of resins and hardeners which
do not
contain compounds on the "Acutely Hazardous Substances"
list in
accordance with
310 CMR 30.00, Commonwealth of Massachusetts Hazardous
Waste
Regulations, may
be placed in the ordinary trash ONLY IF THERE IS LESS
THAN ONE INCH
ACCUMULATION OF RESIN OR HARDENER ON THE BOTTOM OF THE
CONTAINER.
The
labels must be removed before the containers may be placed
in the
trash. Refer
to the SOP to determine whether empty containers may be
disposed of as
ordinary
trash. If further information is needed, contact the
Chemical Hygiene
Officer. If disposal of excess resins or hardeners, cannot
be mixed
because of
insufficient quantities, the containers for these
materials shall be
labeled as
hazardous waste. The specific chemical ingredients or MSDS
shall be
provided
whenever possible.
- Acids and Alkaline Solutions
- Acids and alkaline solutions may
not
be neutralized and put down the
drain. The Mass. Plumbing Code 248 CMR 2.0 along with the
Mas DEP and
MWRA
regulations 360CMR10 prohibit the pouring of any acid or
alkaline
aqueous
solution down the drain except in buildings with
wastewater
neutralization
systems, specifically Buildings 39,68 and 16/56.
Any neutraliztion process that is NOT an
integral part of an experimental
process is considered hazardous waste treatment.
Treatment of hazardous
waste
is not allowed under Federal and State environmental
regulations.
Acids and caustics shall be tightly
capped
and labeled.
- Hydrofluoric acid shall be placed
in
the original plasticized
container or other suitable container with a screw cap.
- Metals
- Arsenic, lead, and heavy metal wastes
should be placed in bottles and
containers, sealed tightly and labeled.
- Alkali metals such as sodium and
potassium shall be placed in a
suitable container, covered with Nujol (mineral oil),
labeled properly,
sealed
so that there is no possibility of their coming in contact
with water.
- Pyrophoric metals such as
magnesium,
niobium, strontium, thorium, and
zirconium, and other pyrophoric chips and fine powders
should be placed
in a
metal container, sealed tightly and labeled.
- Mercury must be removed from lab
apparatus and put into jars or
bottles before sending to the storage area. Broken mercury
thermometers
must
be put into a jar or secondary container. Clean up
materials from a
mercury
spill may be containerized and labeled. Any laboratory or
department
that is
interested in sending mercury to be distilled and to
receive a credit
for the
same, must take the responsibility of having mercury
picked-up by the
proper
disposal vendor.
- Cyanide Compounds
should be placed in
bottles and containers,
sealed tightly and labeled.
- Compressed
Gas cylinders
will not be
picked up by the Environmental Management
Program for removal as hazardous waste. Requisitioners are
responsible
for
asking vendors to supply compressed gases, liquids under gas
and some
solids
either:
- in returnable cylinders, or
- to take back the used "non-returnable"
cylinders. These are also called
"lecture bottles" or "disposable" and require no deposit.
These include
propane torch cylinders.
Otherwise, you may have to pay $500 or more
to
dispose of one non-returnable
cylinder as hazardous waste. All cylinders must be
ordered
through the
"on campus scientific supply vendor" (x3-4761, 18-B90), not
through
General Purchasing or via SAP.
The following vendors currently supply
returnable cylinders (instead of
"disposable" cylinders) and/or take back used non-returnable
cylinders:
| BOC New England |
Linde/Union Carbide |
PCR |
| Cambridge Isotope Labs |
Matheson |
Scott Specialty Gases |
| CVD/Morton International |
Med-Tech |
Spectra Gas |
| Middlesex Welding Supply |
|
|
A more comprehensive list is provided later.
Please note that Alfa doesn't take
back cylinders, but their supplier
may.
Before you leave MIT, the PSFC may require
you
to clean out your laboratory
space and return your cylinders to the vendors, which will
be easier
and more
economical if you have ordered from one of the above
vendors.
- Unknown Waste Chemicals
Unknown waste cannot be accepted for
disposal.
Disposal contractors cannot accept or ship
unknown waste. It is the
responsibility of the department involved to identify all
chemicals and
this
may require polling laboratory personnel, students and
faculty members
to
ascertain the owner of such unknown waste and its identity.
Ultimately
it may
require the services of an analytical laboratory to analyze
the waste.
It must
be constantly emphasized to personnel and students to
identify and
label all
wastes and project products with a chemical name.
- Sink Disposal
The EHS Office has
developed a list of chemicals and materials that may be
discharged into
the
sinks or floor drains. The list is based on regulatory
requirements,
MIT EHS
policy, specific buildings, operations and activities
knowledge, best
practices
and professional judgment regarding the potential impact of a
chemical
if
discharged down the drain.
The list
is
available as a sticker that could be placed near the
sink. Contact Catherine Fiore (Ext 3-8440) for access
to the list
and a sink sticker if needed.
- Waste Oil
- Polychlorinated Biphenyls (PCB's) -
Capacitors, transformers,
equipment and oil that contain PCB's are the
responsibility of the
department
involved. Information on possible disposal contractors can
be obtained
by
calling the Environmental Management Program. (Ext.
2-3477)
- Small Quantities of vacuum pump
oil and lubricating oils should
be collected in 1 gallon containers or less and may be
picked up by the
Environmental Management Program.
- Bulk Quantities of waste oil are
the responsibility of the
department involved.
|
GUIDELINES
FOR
HANDLING
WASTE OIL IN BULK QUANTITIES
|
| Identification: |
Drums of
waste oil need to be identified
with the department name and the
contents of the drum, e.g., hydraulic oil, vacuum pump
oil, etc. |
| Drum: |
The
drums used to store waste oil should be
in good condition. Avoid storing
oil in drums which may be rusty or which may develop
leaks. |
| Inside
Storage: |
The area
where the drums are to be stored
should be a suitable inside area
that is preferably cool and dry. |
| Outside
Storage: |
An
outside storage area for drums should be
protected from the weather,
i.e., in a shed or enclosed area with a roof or some
protection from
the
weather. |
| Secure
Area: |
The
storage area should be secured or
locked to ensure that the contents of
the drums are as identified and belong to the
department involved. The
department may want to have an individual assigned
responsibilities for
this
area so that persons cannot dump waste oil without
authorization. Oils
of
different types need to be kept separate. |
- Solid Wastes
- Inorganic and organic solids in
their original containers that
are designated as waste because they are contaminated,
old, or of
questionable
purity may be picked up by the Environmental Management
Program.
- Physically Dangerous Waste ,
e.g., sharps such as broken glass,
needles, razors, or similarly sharp items, must not be
sent to the
waste
chemical storage area. All sharps must be packaged
properly for
disposal. Syringes must be packaged intact (don't recap
needle or
separate the needle
from the syringe). All sharps must be placed in a puncture
resistant
container. These containers are available from lab supply
(x3-1881).
When the
container is full, seal the container and attach an MIT
"physically
hazardous
waste" label available from the Biohazard Assessment
Program (x3-1740).
The
container may then be left in the hall or next to the
trash barrel for
the
custodian to pick up, but it may not be placed in the
trash.
- Sharps Waste-- Clean needles and
syringes are considered to be
"Medical Waste" and must be packaged in puncture proof
containers. No
tags are needed, but lab number and PI name must be marked
on the
container. If the lab produces a large volume of needles
and syringes,
a BioSystems
container will be provided and a regular pick-up schedule
will be
arranged. Eric Cook ( Ext. 8-5648) is the contact for the
Biohazards
Assessment Program.
- Sharps Waste-- Cleaned and rinsed
glass bottles, glassware,
broken glass, wires, razor blades, tooth picks, and other
sharps from
non-BL
rated laboratories should be collected in a VWR glass box
or other
sturdy
puncture resistant cardboard or plastic container. Any
chemical labels
must
be defaced. Mark the box "clean broken glass" with the lab
number
and person responsible. When full, tape shut and secure.
Place
containers in
the hall. Custodians will pick them up for disposal. If
there are any
problems or questions, contact Kevin Healy, Recycling
Coordinator at
3-360 or
khealy@mit.edu. NO CHEMICAL, RADIOACTIVE, BIOLOGICAL
or HAZARDOUS
WASTE
RESIDUE IS ALLOWED.
- Sharps Waste-- Chemically
contaminated, must be packaged in
puncture proof containers and must be labeled as Hazardous
Waste with
the
chemical contaminants listed. Containers must be managed
in accordance
with
hazardous waste regulations. Chemically contaminated
sharps waste must
not
be packaged in Biohazard containers.
- Radioactive material
disposal is
handled in accordance with
procedures established by the Radiation Protection Program
(Ext.
3-2l80).
- Large quantities
Large quantities of waste
chemicals
to be removed from a
laboratory may be more than a normal amount for the
Environmental
Management Program to pick up and the department will be
financially
responsible for the disposal. Some
examples are the wastes collected in drum lots from a research
project,
clean-out of a laboratory of old reagents and chemicals which
would be
packed
into drums, and the waste chemicals to be pumped out of a
collection or
storage
tank.
- Identification
Containers of chemicals must have the name of
the chemical in English and
the appropriate hazard classification(s), e.g., flammable,
corrosive,
reactive,
toxic, etc. Chemical formulas or foreign names are not
acceptable. All
containers must be labeled prominently because the safe
transportation
of
chemicals is possible only when everyone who handles the
containers
know the
identity of the contents.
- Red Tags
All containers of waste chemicals must have a
"Red Tag" attached to them. This "Red Tag" identifies the type
of
waste, the associated hazards, and the
laboratory or department that created the waste. The red tags
are
available
from the Environmental Management Program. The CHO also keeps
a supply
of
these tags.
- Storage Prior to Pick-Up
- Waste Containers
Containers for chemicals of
one
gallon or larger size shall
be break-resistant whenever possible.
BREAK-RESISTANT shall mean a
container made of metal, plastic,
plastic-coated glass, or metal overpack of glass.
- Secondary Containment
Waste chemicals
stored in breakable
containers of one gallon or larger
size shall be kept within approved secondary containers.
APPROVED SECONDARY CONTAINER shall
mean a commercially available
bottle carrier made of rubber, metal or plastic with
carrying handle(s)
and
which is large enough to hold the contents of the chemical
container.
Lids or
covers are desirable; but not necessary. Rubber or plastic
should be
used for
acids/alkalies; and metal, rubber, or plastic for organic
solvents.
- Caps and Lids
Containers of waste chemicals must be
covered except when waste is being
placed into the container. Do not leave the containers
uncovered or
with a
funnel in place even if the containers are kept in a fume
hood.
- Packaging
Wastes must be packaged and containerized in
a
manner which will allow them
to be transported without the danger of spillage, explosion,
or
hazardous
vapors escaping. Wastes which have not been properly packaged
and
identified
will not be accepted for disposal.
- Paperwork
Department or laboratory personnel requesting
waste pickup from the Environmental Management
Program must fill out a packing list.
The packing list must include the quantity,
chemical name, solid or liquid,
hazards associated with the waste, reactivity, etc.
Environmental
Management Program personnel
will bring the packing list with them when they pick up waste
chemicals.
Lab records may have to indicate how waste
has
been disposed. It is
recommended that responsible individuals keep "on-hand" a copy
of the
most
recent Chemical Waste Packaging List. The EPA may require this
documentation
in the event of an inspection.
