BUILT UP GAS LIKELY CAUSED MYSTERIOUS R.I. BEACH EXPLOSION
Tags: us_RI, public, follow-up, injury, hydrogen
Question: How does sand, seawater, copper, and goo produce enough hydrogen to create an explosion? What is the normal concentration of hydrogen one might expect to find in a sandy beach? The LEL and HEL for hydrogen are 4.0 and 45.0 %. Then, there is always the need for an ignition source. Interesting problem!
