Which of the following is NOT a size category for metal shoring?

Metal shoring is a critical aspect of damage control, particularly in maritime environments. It is used to provide structural support in situations where integrity may be compromised. The size categories for metal shoring typically refer to the weight and height specifications of the shoring equipment, designed to support different loads and spans.

The categories that are standard in metal shoring are often segmented into defined ranges based on their capabilities. The ranges, typically known in increments, are often laid out to indicate different structural uses and effective support limits. Commonly recognized sizes fall within the ranges such as 0-2, 3-5, and 6-11 feet or inches, depending on the specific application and configuration being used.

The category that is not commonly recognized or used in this context is the range referred to as 12-15. This range does not align with standard practices regarding metal shoring and its classifications, thus indicating that it is not a standard size category used in this context. Understanding these size categories is crucial for effective and safe damage control operations, ensuring the right equipment is utilized for the right situation.
