Safety Recommendation P-74-051
Details
Synopsis: ON DECEMBER 6, 1973, A PIPELINE RUPTURED IN A RURAL AREA IN KANSAS, AND RELEASED 2,138 BARRELS OF ANHYDROUS AMMONIA, A VOLATILE, TOXIC MATERIAL. TWO PERSONS WHO HAD DRIVEN THROUGH THE AMMONIA VAPORS WERE HOSPITALIZED WITH BURNS TO THE EYES, NOSE, THROAT, AND LUNGS.
Recommendation: THE NTSB RECOMMENDS THAT THE OFFICE OF PIPELINE SAFETY OF THE DEPARTMENT OF TRANSPORTATION: IN ITS CONSIDERATION TO TAKE REGULATORY ACTION CONCERNING THE METHODS OF HANDLING, CONTAINING, AND DISPOSING OF LIQUEFIED PETROLEUM GASES, INCLUDE NH3. NECESSARY INFORMATION SHOULD BE OBTAINED FROM THE OPS STUDY ON HIGHLY VOLATILE, TOXIC AND/OR CORROSIVE LIQUIDS CURRENTLY UNDERWAY. RULEMAKING SHOULD TAKE INTO ACCOUNT SUCH EXTERNAL FACTORS AS WEATHER CONDITIONS, LEAK SITE TOPOGRAPHY, AND POPULATION DENSITY. ATTENTION SHOULD BE GIVEN TO THE LOCAL TEMPERATURE INVERSIONS CAUSED BY THE RAPID EXPANSION OF THE ESCAPING NH3 AND THE POSSIBLE USE OF EXTERNALLY SUPPLIED HEAT AND AIR BLOWERS TO FORCE THE NH3 VAPORS TO RISE AND DISSIPATE.
