Dear Mr. Dutkiewicz:

This is in response to your September 15, 2000, letter regarding placarding provisions in §§ 172.502 and 172.504(f)(2) of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Your questions are paraphrased and answered as follows:

Q1:      What does the term "permissive placarding" mean as specified in 9 172.502(c)?

Al:        "Permissive placarding" as referenced in § 172.502(c) allows the display of placards for a hazardous material, even when not required, if the placards represent the hazard of the material and otherwise conform to the requirements in Part 172, Subpart F.

Q2:      Section 172.504(f)(2) allows the use of FLAMMABLE placards in place of COMBUSTIBLE placards on a cargo tank or portable tank containing a combustible liquid.  May COMBUSTIBLE placards be displayed on a cargo tank filled with a flammable liquid?

A2:      The answer is no.  A COMBUSTIBLE placard may not be used in place of a FLAMMABLE placard for a cargo tank carrying flammable liquids.

I hope this satisfies your request.

Sincerely,

John A. Gale
