What materials are included in the protective ensembles for technical rescue incidents?

The correct choice highlights essential components of protective ensembles necessary for technical rescue incidents. Helmets, gloves, and boots are critical for ensuring personal safety and protection from various hazards encountered during rescues.

Helmets protect rescuers from falling debris and head injuries, while gloves offer grip and protection when handling equipment or navigating rough terrain. Boots provide necessary foot support and protection from potential hazards like sharp objects or unstable surfaces. The combination of these items creates a foundational level of personal protective equipment that is crucial for safety and effectiveness in rescue operations.

While the other options present various gear items, they do not collectively encompass the fundamental protective requirements in the same way. For instance, safety glasses and reflective vests are important for visibility and protection in certain scenarios but are not as universally required as the trio of helmet, gloves, and boots for all technical rescue operations. Similarly, items like ropes and pulleys are more about operational equipment rather than personal protective gear.
