Dear Mr. Conley:
the applicability of the Hazardous Materials Regulations (HMR; 49
This is in response to your November 28, 2000, letter regarding
parts 171-180) to fuel oil No. 6 with a flash point above
material that has a flash point above 60.5°C (141°F) and below
Under § 173.120 (b) (1), a combustible liquid is defined as a
93°C (200°F) that does not meet the definition of any other
hazard class under the HMR.
Therefore, fuel oil No. 6 with a
flash point greater than 93°C (200°F), that does not meet any
other hazard class defining criteria in Part 173, and is not a
hazardous waste, hazardous substance, or marine pollutant, is not
subject to the HMR.
I hope this satisfies your request.
Sincerely,
Transportation Regulations Specialists
Office of Hazardous Materials Standards

Dear Mr. Mazzullo:
Applicability
00-0350
relative to "fuel oil, (No. 6)." Do the Hazardous Materials Regulations, such
We would appreciate an interpretation of the Hazardous Materials Regulations
s placarding and requirements for shipping papers, apply to a tank truck loa
f fuel oil #6 that has a flash point over 200 degrees Fahrenheit? In othe
words, is a bulk load of fuel oil #6 with a flash point over 200 degrees
Fahrenheit a hazardous material?
We understand that a specification cargo tank would not be required, but
questions have arisen concerning other parts of the regulations-specifically
placarding and shipping papers..
Thank you for an early consideration of this question.
Sincerely,
John L. Conley
Vice President
