(1) A covered entity shall label or ensure that a label satisfying the requirements of this section is already affixed to a covered product with the phrase "WARNING DANGER: Deadly if ingested. If ingested, seek immediate medical attention for intravenous administration of methylene blue. Ingestion of sodium nitrite, even in small quantities, causes severe methemoglobinemia, extreme pain, and imminent death. Keep out of reach of children." This label must be in a size equal to at least two percent of the surface area of the principal display panel, accompanied by a skull and crossbones symbol.

(2) Where the covered product is displayed in advertising or in electronic media, a label notice must accompany the display in no smaller a size than is equivalent to the primary description of the sodium nitrite.

(3) If a covered product is shipped or delivered in packaging that obscures or hides the principal display panel, or is sold in bulk or within the same packaging as another product, the packaging must include a skull and crossbones symbol in a prominent location likely to be seen and read by an ordinary individual under customary conditions of transportation and delivery.

(4) If a federal agency or state department does not approve a product label that otherwise complies with the labeling requirements of this section, the covered entity shall use a label that complies with as many of the requirements of this section as the relevant agency has approved.
