Honeywell (289, 183605), Baton Rouge

Causal Factor: Seal or Gasket

LDEQ Accident Number
Accident Date
Point Source(s) Notes Amount of Release

Transfer hose
Cause: An operator who was unloading a chloroform railcar notices a leaking hose. The leak had started between the hours of 3:15 am, when the unloading began, and 6:45 am, when the leak was stopped. The cause of the leak was a gasket failure on the transfer hose.

Followup: No

Notes: Prior to unloading the railcar, the operator checked the hoses and found no leaks. Once the leak was discovered, the chloroform transfer was terminated to stop the leakage from the hose. The facility's emergency response team isolated the leak and cleaned up the area. The waste material was placed in an approved DOT container. The facility stated in its letter that it plans to conduct a detailed analysis of the gasket, the unloading operation, and others.
Chloroform: 1,253.0 pounds

G-22 relief valve
Cause: During operation of the G-22 unit the South Joy compressor was over pressurized causing a relief valve in the inner cooler portion of the machinery to lift. The relief valve failed to reseat properly causing a realase of 3580 lbs of Chlorodifluoromethane (G-22).

Followup: No

Chlorodifluoromethane: 3,580.0 pounds

line off of the HF storage tank
Liquid line off of the HF storage tank
Cause: Liquid line off of the HF storage tank leaked from a flange.

Followup: No

Notes: The line was drained to the HF scrubber for discharge into the plant's effluent treatment system. Pulled the liquid to scrubber and it was overloaded. Once in the process wastewater line the HR reacted with caustic causing G-113 to be released to atmosphere.
Hydrofluoric Acid: 3.8 pounds
Trichlorotrifluoroethane (G-113): 302.0 pounds

tank car loading/unloading area
Cause: Approximately 14578 lbs of Trichlorotrifluoroethane was released due to a gasket failure in the load/transfer hose while filling the tankcar.

Followup: No

Notes: The chemical was released onto the railroad tracks, cross ties, gravel and soil underneath the tank car. The product was initially contained by a large dyke of oil dry. MasterVac had been called to vacuum up the product. Gravel and soil had been dug up to about a foot, new soil had been added, and gravel was being placed back in the track bed. The new cross ties were being laid in place. The soil/gravel had been placed into a rolloff and the cross ties had been placed into another rolloff. The two roll offs were going to Waste Management. The liquid product that was recovered had been placed into a drum. The drum was to be sent for incineration.
1,1-Dichloro-2,2,2-Trifluorethane (G-123): 14,578.0 pounds

gasket on the isocontainer
Cause: Tank farm operations were in the process of loading an isocontainer with R-410a when the gasket between the flange of the internal valve and the isocontainer tank failed. Operations closed both internal and external valve and attempted to tighten the flange nuts, but were unsuccessful in stopping the leak.

Followup: No

Notes: The point of the leak was at the gasket upstream of the internal valve and flange to the isocontainer. Operations immediately began to unload the contents of the isocontainer back to the railcar. The release did not result in any fire or explosions, and there were no injuries as a result of the incident. The release exceeded the reportable quantity of 5000 pounds of R-410a. Corrective actions have been initiated to prevent any reoccurence.
R410a: 8,247.0 pounds
