Not a direct answer, but there is a standard code for what actions emergency services should take, and the code[1] for this stuff is 3YE, which means "Use foam or dry agent, substance reacts violently/is explosive, BA [breathing apparatus] use is essential, evacuate vicinity, contain spill." So there must be some reason not to let the stuff out.
[1] This is the hazchem code. I think the US uses a different system. A list is here: https://www.ricardo.com/media/radn55jg/dangerous-goods-emerg...
The US uses the Emergency Response Guide or ERG, which similarly lists more or less all hazardous materials and suggests appropriate responses.

Relevant guide is 129, which is on PDF page 189.
---------
SPILL OR LEAK
• ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.
• All equipment used when handling the product must be grounded.
• Do not touch or walk through spilled material. • Stop leak if you can do it without risk. • Prevent entry into waterways, sewers, basements or confined areas.
• A vapor-suppressing foam may be used to reduce vapors.
• Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers.
• Use clean, non-sparking tools to collect absorbed material.
Large Spill
• Dike far ahead of liquid spill for later disposal.
• Water spray may reduce vapor, but may not prevent ignition in closed spaces.
