The hazard marking minimum dimensions for Genetically Modified Organisms must be at least:

• A. 50 mm x 50 mm
• B. 4 mm x 4 mm
• C. 100 mm x 100 mm
• D. 500 mm x 500 mm

Answer: (A)

Hazard markings on Genetically Modified Organisms must be large enough to be clearly seen and read during handling, transport, and storage. The minimum size is set to ensure the symbol and any accompanying text remain legible from a reasonable distance and on various package sizes, even when the package is moved, stacked, or exposed to elements. Fifty millimeters by fifty millimeters hits that balance: it’s big enough to read reliably, yet practical for typical packaging.

Smaller marks, like 4 mm by 4 mm, would be unreadable in real-world conditions. Markings that are much larger, such as 100 mm by 100 mm or 500 mm by 500 mm, go beyond what’s needed for a minimum requirement and can be impractical for small packages or clutter packaging surfaces.
