Sec. 157.22  When required.

    Unless exempted under Sec. 157.24, a pesticide product must be 
distributed and sold in child-resistant packaging complying with Sec. 
157.32 if it meets both of the following criteria:
    (a) Toxicity criterion. Based upon testing with an appropriate test 
species, the product meets any of the following toxicity criteria:
    (1) The pesticide has an acute oral LD50 of 1.5 g/kg or 
less;
    (2) The pesticide has an acute dermal LD50 of 2000 mg/kg 
or less;
    (3) The pesticide has an acute inhalation LC50 of 2 mg/
liter or less;
    (4) The pesticide is corrosive to the eye (causes irreversible 
destruction of ocular tissue) or causes corneal involvement or 
irritation persisting for 21 days or more;
    (5) The pesticide is corrosive to the skin (causes tissue 
destruction into the dermis and/or scarring) or causes severe skin 
irritation (severe erythema or edema) at 72 hours; or
    (6) The pesticide or device has such characteristics that, based 
upon human toxicological data, use history, accident data or such other 
evidence as is available, the Agency determines there is serious hazard 
of accidental injury or illness which child-resistant packaging could 
reduce; and
    (b) Use criterion. The product's labeling either directly recommends 
residential use or reasonably can be interpreted to permit residential 
use.
