Placement of the Label

In general, the EPA requires that the label appear on or be securely attached to the immediate container of the pesticide product (162.10(a)(4)). The regulations define securely attached as meaning that a label can be reasonably expected to remain affixed to the container during the foreseeable conditions and period of use. If the product is packaged in an outside wrapper then either the label must be clearly readable through that wrapper, or if not, it must be securely attached to the wrapper or outside container. 

Pesticides in transit in bulk are subject to the labeling, marking, and placarding provisions of 49 CFR 170-189, concerning transportation of hazardous materials. A copy of the accepted EPA label must be attached to the papers that accompany the shipment and must be left with the consignee at the time of delivery. Similarly, pesticides stored in bulk, in the custody of the user, must have a copy of the EPA s approved label attached securely to the container in the immediate vicinity of the discharge valve.

There are a number of requirements in the existing systems that relate to size, appearance, and placement of the labels. For example, the Canadian Workplace Hazardous Materials Information System (WHMIS) system requires a border around the label that distinguishes it from labels of other systems. 

The term isotopomer designates a variant of a molecule with a different net isotopic content. Except for the isotopic difference, the two molecules must otherwise have identical structures. Three isotopomers of phenol provide an example. The ( 3C)phenol drawn as structure [1] represents an isotopomer of phenol containing only But [1] is not an isotopomer of structure [2], which also contains one 3C. Instead [1] and [2], properly speaking, are isotopic isomers, differing only by the placement of the labelled atom.
