EXPLOSIVE

Since the frequency of explosive loads is limited to Division 1.4 (approximately 6-10 loads per year) and the size of such shipments is non-bulk packages loaded in a container or van at one time, it is our estimate that the degree of vulnerability is 50% due to the placarding requirements. However, since the potential impact of the use of fireworks as weapons of mass destruction is low our overall assessment of risk for explosives is scored at 15%.

Non-bulk cylinders of compressed gases are shipped occasionally through our distribution system; therefore the degree of vulnerability is medium at 50%. Since these cylinders may be used as a component of a weapon our assessment of risk for compressed gas in 30%.

The shipments made within our distribution system are primarily paints, flammable PGII and PGIII ranging in size from one gallon cans to 4000 pound portable tanks. Therefore the degree of vulnerability for flammable liquids is deemed to be high at a rate of 50%. Since flammable liquids may be a component of a weapon as well as pose a significant threat itself, our determination for the potential impact of the risk for flammable liquids is 60%.

The few shipments made within our distribution system that involve oxidizers are in non-bulk packages in very limited quantities. Oxidizers are generally used as a catalyst to get a reaction started and therefore could be useful in a weapon of mass destruction. The degree of vulnerability for oxidizers is very high at 75%. Our determination for the potential impact of the risk for oxidizers is 75%.

WARNING: This record contains Sensitive Security Information that is controlled under 49 CFR parts 15 and 1520. No part of this record may be disclosed to persons without a “need to know”, as defined in 49 CFR parts 15 and 1520, except with the written permission of the Administrator of the Transportation Security Administration or the Secretary of Transportation.

The few shipments containing poisons, especially poisons by inhalation hazard, may be considered a weapon of mass destruction in their existing form. Therefore the potential impact of risk for poisons in our system is medium to high 65% regardless of quantity.

The shipments of corrosives are typically shipped in the form of different sizes of batteries in non-bulk packages. The maximum weight is 40,000 pounds per shipment. Due to the potential of high jacking for the chemicals to be used in weapons of mass destruction, the degree of vulnerability for corrosives is high at 80%. Violent reaction can be expected; as a result of the use of corrosives in a mixture therefore causing the potential impact of risk for corrosive in our system is high at 50%.

Several shipments of Class 9 move through our system on a fairly regular basis resulting in a vulnerability of an incident of 50%. However, the risk of a Class 9 being used in a weapon of mass destruction are estimated to be very low, therefore our overall estimate of potential risk for miscellaneous materials is 15%.
