Abstract: About 8:30 a.m. on November 21, 1996, because of a
propane gas leak, a commercial building in San Juan, Puerto Rico, exploded.
Thirty-three people were killed, and at least 69 were injured. The safety
issues discussed in this report are the adequacy of employee training,
the need for an excavation-damage prevention program, the adequacy of maps
and records of buried facilities, the adequacy of public education on what
to do when the odor of gas is detected, and the adequacy of the oversight
of the San Juan Gas Company, Inc., from Enron Corp., the Puerto Rico Public
Service Commission, and the Office of Pipeline Safety. As a result of its
investigation, the National Transportation Safety Board issued recommendations
to the Secretary of the U.S. Department of Transportation, the Research
and Special Services Administration, the Puerto Rico Public Service Commission,
Enron Corp., and Heath Consultants, Inc.
