Which stabilizing tool is used to support collapsed structural members during rescue operations?

• A. Pry bars
• B. Bar Screw Jacks
• C. Come-Alongs
• D. Hydraulic Spreaders

Answer: (B)

Stabilizing collapsed structures requires an adjustable, high-load support that can be set precisely and locked in place. Bar screw jacks provide that capability: they deliver strong vertical support and allow fine height adjustment to fit against a collapsed member and cribbing, then be secured to prevent movement. This creates a stable, controllable base so rescuers can work without the risk of further settlement or collapse.

Pry bars are for prying and levering, not for maintaining a supported stance under heavy loads. Come-alongs pull or apply tension but do not offer a stable, bearing-supported position and can slip under load. Hydraulic spreaders are meant to create space by expanding openings, not to hold up or stabilize a load. In rescue operations, the most reliable option for stabilization is bar screw jacks.
