Ref. No. 08-0123
Dear Mr. Grindal:
This responds to your letter requesting clarification of the requirements for infectious
substances and regulated medical waste (RMW) under the Hazardous Materials Regulations
(HMR; 49 CFR parts 171-180). You ask several questions that I have paraphrased and
answered below:
Q1. Our facility generates sharps contaminated with medical waste. If we were to
chemically disinfect these sharps with a ten percent (10%) bleach solution, would they
be subject to the HMR as Division 6.2 materials?
Al. A material that may or may not have contained a pathogen that has been neutralized or
inactivated such that it no longer poses a risk is not regulated as a Division 6.2
material.
Q2. If an offeror determines a particular medical waste presents greater hazardous
characteristics than a Division 6.2, is it permissible to classify that waste with a
subsidiary risk of Division 6.2?
A2. No. In accordance with $ 173.2a(c)(3), a Division 6.2 material that also meets the
definition of another hazard class or division, other than Class 7, or that also is a
limited quantity Class 7 material, must be classed as Division 6.2.
Q3. Is it permissible to transport a RMW that meets the definition of another hazard class
in the same transport vehicle that also contains a non-medical waste material being
transported to a non-medical waste disposal facility under the exceptions for RMW in
$ 173.134(~)(1) and (c)(2)?
A3. The exception in $ 173.134(~)(1) permits RMW when transported by a private or
contract carrier to be excepted from certain labeling and packaging requirements of
the HMR. For other than waste cultures and stocks, there are no restrictions on the
types of materials that may be transported on the same vehicle as RMW. Thus, you

may transport other non-medical waste materials on the same vehicle as RMW,
provided the shipment does not contain waste cultures and stocks. Additionally, if the
RMW meets the definition of another hazard class, it must be offered for
transportation and transported as required by the HMR.
The exception in $ 173.134(~)(2) permits Category B waste cultures and stocks to be
transported as regulated medical waste when packaged in a rigid non-bulk packaging
conforming to certain general packaging requirements and transported by a private or
contract carrier in a vehicle used exclusively to transport RMW. An exclusive-use
vehicle is one used for the transportation of a single commodity or class of
commodities. Transportation in an exclusive-use vehicle in accordance with the
exception prevents inadvertent contamination of other types of materials, including
non-medical waste materials. Thus, you may not transport non-medical waste
materials on the same vehicle as RMW that contains waste cultures and stocks.
Additionally, if the RMW meets the definition of another hazard class, it must be
offered for transportation and transported as required by the HMR.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
Hattie L. Mitchell

Comments: This e mail is sent with the intent to receive a written interpretation and
guidance concerning the relevent HMR citations. A hospital in the process of patient care
generates a waste that has contacted human bodily tissues and still contains a DOT PGIII
toxic substance (i.e. a hypodermic needle containing Epinephrine HCL). Additionally, an
alcohol wipe with a resovoir of Isopropanol has contacted blood and other bodily tissues.
These wastes were generated in a surgical suite during an operation and both materials
were placed in the same sharps container. With regards to transporting this waste I have
the following questions:
1) Per 173.134 (b)(4): If this waste was chemically disinfected with a 10% bleach solution
prior to sealing the container would it be considered a Division 6.2 material when offered
for transport?
2) Per 173.24a (c)(3): This citation states that an infectious substance must be classed a
division 6.2. Can the 6.2 be a subsidiary hazard class if the shipper determines another
? ? , i" (173.2a)?
hazard class presents a greater danger?
er 173.134 (a) (1) (ii): If this waste is determined to be a Regulated Medical Waste,
6.2, UN3291 can the waste also be classed a division 3 and division 6.1 as subsidiaries
-4) Per 173.12 (b): When the above listed waste is sealed in a sharps container and placed
within a DOT PGII packaging with other compatible materials, can this package be

transported on the same motor vehicle with wastes other than Medical Wastes, specifically
hazardous wastes being transported to a non medical waste disposal facility (173.134 (c))?
Please let me know if you have any questions.
Thank you.
