Hazardous Materials: Exceptions From Labeling and Placarding Materials Poisonous by Inhalation (PIH)

Summary: In an interim final rule published on September 16, 1999, and amended on September 24, 1999, RSPA provided a limited exception, until October 1, 2001, from requirements to place new POISON INHALATION HAZARD or POISON GAS labels on packages of PIH materials to facilitate international transportation. This final rule responds to two comments received on the interim final rule, extends the provisions of the interim final rule, and provides additional exceptions from requirements to place new POISON INHALATION HAZARD or POISON GAS labels and placards on certain packages and transport vehicles in international transportation.
