PART 156_LABELING REQUIREMENTS FOR PESTICIDES AND DEVICES--Table of 

Contents

 

           Subpart D_Human Hazard and Precautionary Statements

 

Sec. 156.62  Toxicity Category.



    This section establishes four Toxicity Categories for acute hazards 

of pesticide products, Category I being the highest toxicity category. 

Most human hazard, precautionary statements, and human personal 

protective equipment statements are based upon the Toxicity Category of 

the pesticide product as sold or distributed. In addition, toxicity 

categories may be used for regulatory purposes other than labeling, such 

as classification for restricted use and requirements for child-

resistant packaging. In certain cases, statements based upon the 

Toxicity Category of the product as diluted for use are also permitted. 

A Toxicity Category is assigned for each of five types of acute 

exposure, as specified in the table in this paragraph.
