What does NFPA 1983 specify about auxiliary equipment?

The correct choice emphasizes the importance of product labels on auxiliary equipment as specified by NFPA 1983. These labels serve critical functions, including providing essential information about the equipment's specifications, compliance with safety standards, and proper usage. The presence of comprehensible labels ensures that users can easily identify the equipment's capabilities and limitations, which is vital for safe and effective operations in rescue situations.

Labeling also aids in the accountability of equipment maintenance and inspections, as it often includes details about the manufacturer, model number, and the equipment's testing criteria or standards met. This aligns with the NFPA's objectives to ensure that all equipment used in technical rescues is reliable, safe, and suitable for the intended applications.

While the other options touch on important aspects of equipment management, they do not capture the specific requirements set forth by NFPA 1983 regarding the need for product labels, which directly support safe practices in rescue operations.
