Ref. No.: 11-0107
Dear Mr. Chammas:
This responds to your May 11,2011 letter requesting clarification of the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) applicable to UN 1746, Bromine Trifluoride,
5.1(6.1)(8), PG I, Poison Inhalation Hazard Zone B. Specifically you ask what placards are
required when shipping less than 1,000 pounds of this material.
Under the HMR, OXIDIZER placards for the primary hazard and POISON INHALATION
HAZARD placards are required for your material, as prescribed by §§ 172.504(e) Table 2,
and 172.505(a) respectively. The 454 kg (1,001 pounds) exception in § 172.504(c) does not
apply to a material that is required to display a subsidiary POISON INHALATION HAZARD
placard in accordance with § 172.505(a). As specified in § 172.505(d), display of the
CORROSIVE placard for the subsidiary hazard is permissible, but not required.
I trust this satisfies your inquiry. Please contact us if we can be of further assistance.
Sincerely,
T. Glenn Foster
Chief, Regulatory Review and Reinvention Branch
Standards and Rulemaking Division

To Whom It May Concern,
I am writing to request clarification of placarding provisions listed in the HMR, 49 CFR. Our question
is as follows:
What placards are required on a vehicle transporting less than 1,000 Ibs of non-bulk packages
containing UN1746, Bromine Trifluoride, 5.1 (6.1){8), PG I, Poison Inhalation Hazard Zone B?
Specifically, is the corrosive placard required?
Thank you,
Michel Chammas
