Evacuation Zone Expanded in NJ Toxic Train Derailment

The US Coast Guard has expanded the evacuation zone in Paulsboro NJ (Gloucester County)  following the toxic derailment of a train carrying deadly cancer causing vinyl chloride. Evacuations have been mandatory since last Friday when a movable bridge failed to function and collapsed when a freight train was moving over it.

The National Transportation Safety Administration (NTSB) is co-ordinating an intensive accident investigation. The NTSB reported yesterday that the bridge had problem and that the train engineer contacted a Conrail dispatcher for authorization to cross the bridge even though the bridge signal was red indicating bridge trouble. The NTSB also reported that the bridge was inspected by two Conrail supervisors shortly before the event because of trouble signal being sent by the bridge safety mechanism.

Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic and vinyl products. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system effects (CNS), such as dizziness, drowsiness, and headaches in humans. Chronic (long-term) exposure to vinyl chloride through inhalation and oral exposure in humans has resulted in liver damage. Cancer is a major concern from exposure to vinyl chloride via inhalation, as vinyl chloride exposure has been shown to increase the risk of a rare form of liver cancer in humans. EPA has classified vinyl chloride as a Group A, human carcinogen.

US NTSB Initiates Investigation of NJ Toxic Train Derailment

The US National Transportation Safety Board (NTSB) has now commenced an investigation of the train accident in Paulsboro, New Jersey where a moveable bridge collapsed and the 84 car train, with 4 cars of toxic substance crashed into a creek spilling hazardous vinyl chloride. 
The NTSB is a Federal agency charged with accident investigation. It has begun to collect data, both human and mechanical, to determine the cause of the investigation. A team of investigators has from Washington DC and other areas of the country has now appeared on the scene to commence the investigation. After conclusion of the investigation and analysis as to the its cause, the NTSB will issue
recommendations to prevent further similar accidents.

The same bridge was had collapsed in 2009, when a train pulling coal cars came off its tracks after the railroad bridge over the Mantua Creek collapsed and sent 16 cars into the water. The bridge was “an old structure,” and its original “A” frame dated back to 1873. The train has two locomotives and 83 freight cars.

One tanker containing 25,000 gallons of vinyl chloride. It was breached in the accident. The gas leaked into the air, while the rest turned into a solid and settled into the bottom of the tanker. Elevated levels of vinyl chloride were detected in a 12 block radius and over 500 people were evacuated last night. Approximately 70people have been treated at the local hospital. No fatalities have yet to be reported.

Train Carrying Deadly PVC Crashes In NJ Sickens Workers / Residents

A train carrying deadly Polyvinyl Chloride (PVC) crashed in NJ this morning when a bridge it was traveling on collapsed. The train containing highly toxic cargo crashed while crossing a creek near the Delaware River. 

It has been reported that at least 71 people are being treated for respiratory distress and residents have been ordered to remain indoors. The train remains dangling from the collapsed bridge and and chemicals continue to leak into the creek.

Most vinyl chloride is used to make polyvinyl chloride (PVC) plastic and vinyl products. Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system effects (CNS), such as dizziness, drowsiness, and headaches in humans. Chronic (long-term) exposure to vinyl chloride through inhalation and oral exposure in humans has resulted in liver damage. Cancer is a major concern from exposure to vinyl chloride via inhalation, as vinyl chloride exposure has been shown to increase the risk of a rare form of liver cancer in humans. EPA has classified vinyl chloride as a Group A, human carcinogen.

Acute Effects: Acute exposure of humans to high levels of vinyl chloride via inhalation in humans has resulted in effects on the CNS, such as dizziness, drowsiness, headaches, and giddiness. Vinyl chloride is reported to be slightly irritating to the eyes and respiratory tract in humans. Acute exposure to extremely high levels of vinyl chloride has caused loss of consciousness, lung and kidney irritation, and inhibition of blood clotting in humans and cardiac arrhythmias in animals. Tests involving acute exposure of mice have shown vinyl chloride to have high acute toxicity from inhalation exposure.

Chronic Effects(Noncancer): Liver damage may result in humans from chronic exposure to vinyl chloride, through both inhalation and oral exposure. A small percentage of individuals occupationally exposed to high levels of vinyl chloride in air have developed a set of symptoms termed “vinyl chloride disease,” which is characterized by Raynaud’s phenomenon (fingers blanch and numbness and discomfort are experienced upon exposure to the cold), changes in the bones at the end of the fingers, joint and muscle pain, and scleroderma-like skin changes (thickening of the skin, decreased elasticity, and slight edema). CNS effects (including dizziness, drowsiness, fatigue, headache, visual and/or hearing disturbances, memory loss, and sleep disturbances) as well as peripheral nervous system symptoms (peripheral neuropathy, tingling, numbness, weakness, and pain in fingers) have also been reported in workers exposed to vinyl chloride. Animal studies have reported effects on the liver, kidney, and CNS from chronic exposure to vinyl chloride. EPA has established a Reference Concentration (RfC) of 0.1 milligrams per cubic meter, and a Reference Dose (RfD) of 0.003 milligrams per kilogram per day for vinyl chloride. Please see IRIS for current information.

Reproductive/Developmental Effects: Several case reports suggest that male sexual performance may be affected by vinyl chloride. However, these studies are limited by lack of quantitative exposure information and possible co-occurring exposure to other chemicals. Several epidemiological studies have reported an association between vinyl chloride exposure in pregnant women and an increased incidence of birth defects, while other studies have not reported similar findings. Epidemiological studies have suggested an association between men occupationally exposed to vinyl chloride and miscarriages in their wives’ pregnancies although other studies have not supported these findings. Testicular damage and decreased male fertility have been reported in rats exposed to low levels for up to 12 months. Animal studies have reported decreased fetal weight and birth defects at levels that are also toxic to maternal animals in the offspring of rats exposed to vinyl chloride through inhalation.

Cancer Risk: Inhaled vinyl chloride has been shown to increase the risk of a rare form of liver cancer (angiosarcoma of the liver) in humans. Animal studies have shown that vinyl chloride, via inhalation, increases the incidence of angiosarcoma of the liver and cancer of the liver. Several rat studies show a pronounced early-life susceptibility to the carcinogenic effect of vinyl chloride, i.e., early exposures are associated with higher liver cancer incidence than similar or much longer exposures that occur after maturity. EPA has classified vinyl chloride as a Group A, human carcinogen. EPA uses mathematical models, based on animal studies, to estimate the probability of a person developing cancer from breathing air containing a specified concentration of a chemical.

EPA has calculated an inhalation unit risk estimate of 8.8 × 10-6 (µg/m3)-1 for lifetime exposure to vinyl chloride.
