A pinhole in a container is typically identified by light leaking into the container. This phenomenon occurs because a pinhole, being a very small hole, allows light to pass through, indicating that there is a breach in the container's integrity.

Identifying damage through light penetration is a crucial inspection method, as it often signifies that other forms of contamination, such as moisture or pests, might also be able to enter. Detecting these small openings is essential for maintaining the container's ability to protect its cargo from external elements.

Visible rust on the outside or water pooling at the bottom may indicate other types of damage or decay but do not specifically relate to identifying a pinhole. A strong odor from inside the container could suggest spoilage or contamination but would not directly pinpoint the presence of a pinhole. Thus, light leaking into the container serves as a more immediate and reliable indicator of the specific issue at hand.
