On November 15, 1984, the Agency issued PR Notice 84-5, Label Improvement Program for Fumigants, which prescribed label changes for fumigant products registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The notice required that product labels for 11 fumigants and mixtures be revised in a number of ways, including upgraded precautionary statements, required use of respirators and detector devices, inclusion of reentry threshold levels, safe handling and disposal instructions, and in some cases, restricted use statements. Based on comments received after the notice was issued, and on other developments pertinent to fumigant products, the Agency is making revisions and clarifications to PR Notice 84-5. At the same time, the Agency is extending the deadlines for making the revisions to accommodate these changes.
