In this chapter, unless the context or subject matter otherwise requires:
Provided, the department, by regulation, shall exempt from subdivision a those articles, such as chemical sets, which by reason of functional purpose require the inclusion of the hazardous substance involved, and which bear labeling giving adequate directions and warnings for safe use, and are intended for use by children who have attained sufficient maturity and may reasonably be expected to read and heed these directions and warnings.
The term "hazardous substance" applies to any article which is not an economic poison within the meaning of the Federal or North Dakota Insecticide, Fungicide, and Rodenticide Act of 1947, and which is a hazardous substance within the meaning of this subsection by reason of bearing or containing an economic poison.
