Dear Mr. Ritchie:

This is in response to your letter dated August 7, 1997, requesting clarification of the placarding requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Your questions are paraphrased and answered as follows:

Q1. A truck in interstate commerce is carrying 800 pounds of Chlorine, 2.3, UNlOl7u, a poisonous gas with subsidiary hazard Class 8 (corrosive), in non-bulk cylinders with no other hazardous material on board. What placard(s) are required?

A1. Both POISON GAS and CORROSIVE placards are required, as prescribed by
§ 172.505(a).

Q2. A truck in interstate commerce carries 1,500 pounds of "Chlorine, 2.3, UNI017," a poisonous gas with subsidiary hazard Class 8 (corrosive), in non-bulk cylinders with no other hazardous material on board. What placard(s) are required? Since the load exceeds 454 kg. has the placarding requirement changed because of the subsidiary hazard?

A2. The answer is the same as in A1. The fact that the load exceeds 454 kg does not alter the placarding requirement.

Q3. A truck in interstate commerce carries, in non-bulk packagings, 800 pounds of "Bromine, 8, UN1744, PG I," a poisonous-by-inhalation Hazard Zone A material that is corrosive and has a subsidiary hazard class of Division 6.1 (poisonous material). What placard(s) are required?

A3. Both POISON INHALA nON HAZARD and CORROSIVE placards are required, as
prescribed by § 172.505(a).

I hope this information is helpful. Should you have further questions, please contact us.

Sincerely,
