The term "misbranded parcel, package, or container" means a retail parcel, package, or container of any dangerous caustic or corrosive substance for household use, not bearing a conspicuous, easily legible label or sticker, containing:
The name of the article;
The name and place of business of the manufacturer, packer, seller, or distributor;
The word "POISON," running parallel with the main body of reading matter on said label or sticker, on a clear, plain background of a distinctly contrasting color, in uncondensed gothic capital letters, the letters to be not less than 24 point size, unless there is on said label or sticker no other type so large, in which event the type shall be not smaller than the largest type on the label or sticker, and
Directions for treatment in case of accidental personal injury by the dangerous caustic or corrosive substance. Such directions need not, however, appear on labels or stickers on parcels, packages, or containers at the time of shipment or of delivery for shipment by manufacturers or wholesalers for other than household use.
