Transportation of Hazardous Materials
Guidelines have been developed regarding the transport of
hazardous chemicals such as acids and corrosive liquids, flammable
solids and liquids, toxic chemicals, oxidizers and reactive
chemicals, (including waste containing such chemicals) from
one room to another within a building or from building to
building. The guides require: (1) using a proper container,
(2) utilizing a proper transporting device, or (3) limiting
the size and quantity transported. Other hazardous chemicals,
such as compressed gas cylinders, biohazards, radioactive
materials, carcinogenic compounds, etc., require special precautions.
D.O.T. shipping boxes are available from EH&IS at extension
7233 for safe transporting of hazardous materials.
Glass Bottles
- The transport of large glass bottles (one gallon
or larger) by hand shall be done in a proper carrier.
Acceptable carriers include a plastic acid or bottle
carrier, Styrofoam casing, or appropriate cardboard
box, wooden crate, etc. In general, depending on the
hazard, a single glass bottle of one quart or less may
be carried by hand, except inside an elevator (see 1e.).
- Whenever more than one glass bottle of any size is
being transported, it is necessary that measures be
taken to prevent the glass bottles from contacting each
other. Such devices as cardboard boxes with dividers,
Styrofoam cases with compartments, or the use of vermiculite
filler is appropriate.
- If a cart is employed to transport glass bottles
within a building, precaution must be taken to prevent
the glass bottles from contacting each other and/or
falling off the cart. Glass bottles shall not be placed
loosely on a cart unless the cart is specially designed
to accommodate the bottles, or the bottles are in protective
containers, such as described above. The cart shall
have an adequate lip to prevent packages from slipping
off the cart.
- Anytime glass bottles are to be transported from
building to building, additional precaution must be
taken. The cart used should have larger wheels (4";
minimum), preferable of a pneumatic type. The cart
should have at least a 3" lip and all bottles should
be transported in some type of protective container,
such as described above.
- Transport within elevators always requires an acceptable
carrier as described above.
Plastic Coated Bottles/Metal Cans/Safety Cans
- The hand carrying of these kinds of containers is
permitted since the integrity of the container is far
superior to that of the glass bottle. If any of these
containers are involved in an accident, it is not likely
that the entire contents of the container would be immediately
spilled or splashed about. There also would be little
or no glass fragments.
- Whenever more than two of these containers are being
transported, an additional carrying device, such as
an appropriate cardboard box or a wheeled cart with
a lip should be employed. Follow the precaution given
for the type of cart as outlined above.
Cardboard Cartons, Crates, Boxes Containing Chemicals Bottles
When transporting chemicals in their original shipping packages,
normal transporting methods may be used, such as pushcarts
and dollies. If these containers must be transported on
outdoor paths, the precautions listed above for bottles
shall be followed, unless the packages can be adequately
secured to the cart or the dolly.
Chemical Ordering Do's and Don'ts
- Whenever the chemical is available in a plastic coated
bottle, order it that way.
- Whenever a flammable liquid is available in the MCB
SAF-T-CAN (glass bottles inside metal can), order it
that way.
- Do not order more of one chemical than you will utilize
in normal operations. Overstocking to save money on
large quantities creates many other problems, such as
exceeding the permissible amount of flammable liquids
in a lab, or increasing the possibility of the chemicals
getting old before they are consumed. Old chemicals
may become hazardous due to aging, and disposal is always
costly. If the overstock is not used it will likely
have to be shipped off as waste at extra cost to the
campus.
Biohazard Transport
Transport of biohazards to other labs or facilities requires
suitable enclosed containers. Contact Environmental Health
and Instructional Safety Office for assistance if a biohazard
(or suspected biohazard) is delivered to your area.
Cylinder Transport
Whenever compressed gas cylinders are moved, caps must be
placed over the valves and suitable carts with securing
devices used. Cylinders have to be secured to the bench
or wall of labs at all times using the campus standard two
chain method. Freestanding cylinders, or
cylinders moved without a cart, may become "unguided
missiles" if they fall and the cap is broken.
Transporting of Radioactive Materials
Transportation of all radioactive materials and waste must
be performed under the supervision of the Radiation Safety
Officer.
Transport of Chemical Carcinogens
Personnel utilizing carcinogens or suspect carcinogens should
be aware of the hazards involved in transporting these chemicals.
The risk can be reduced by using sealed containers, such
as plastic bags, which are large enough to contain the material
if spillage or breakage occurs. The sealed bags shall then
be placed in an airtight can, such as a paint can. A warning
label shall identify the substance, its carcinogenicity
(use "Caution -- Cancer Suspect Agent"), and the
quantity, with the researcher's name and department. This
procedure is the NCI recommended practice not only for transport,
but also for storage of such materials. Please refer to
Chemical Hygiene Plan for more information on proper handling
and storage of carcinogens. ("Handling Chemical
Carcinogens - A Safety Guide for the Laboratory
Researcher"; contains additional information and is
available from EH&IS)
Finally, never utilize a private vehicle for transporting
hazardous materials.
Always consult Environmental Health and Instructional Safety
Office if in doubt as to safe procedures.
