In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class).

In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
