The man killed in an explosion in a Menlo Park laboratory Friday (Sept. 2) has been identified as 56-year-old Adrian Martin of San Jose, the San Mateo County Coroner's Office said Sunday.
Martin, a scientist at Membrane Technology and Research Inc. at 1360 Willow Road was preparing a pre-gas mixture involving methane, helium and nitrogen when the 4:07 p.m. explosion occurred, according to Menlo Park Fire Chief Harold Schapelhouman.
A female coworker standing near the door of the lab was thrown clear by the explosion and survived with only some damage to her eardrum.
Martin was seriously injured. He was recovered from the lab, but he then suffered cardiac arrest and died at the scene, Schapelhouman said.
Fire officials found a leaking methane cylinder in the lab, although it was not clear if the cylinder was leaking before the explosion or if it was caused by the blast, he said.
More than 20 employees were evacuated from the business, and a hazardous-materials team responded to ensure that the area was safe.
