When approaching a train hazard, one must understand that identification is usually found on the right side, lower right corner or on the rear of the rail car. Tank cars typically transport solids, liquids or gases that may or may not be under pressure. Therefore, it is important to read the shipping documents or contact dispatch before responding. In many European and South American transport vehicles, the hazard number is listed on the top half of an orange panel, while the four digit identification number is listed on the bottom half. The hazard number is listed either with a zero following it to indicate a basic hazard, while a double digit is listed to indicate an intense hazard.

Contact 911 and notify the pipeline operator. Not only is natural gas delivered through pipelines but crude oil, refined gas and hazardous liquids are often transported through pipelines as well. The safety protocols listed for natural gases can be followed for these types of pipeline materials as well. Since most fires are fought with water, it is important to understand that water may be ineffective or more harmful when dealing with certain materials. The guide numbers listed in the orange section, can point firefighters to the correct method for extinguishing the fire. Often times fighting a flammable liquid, fire will need a chemically mixed foam instead of water. The emergency response number listed on the shipping document should be contacted quickly to inform firefighters of the correct method and potential hazards they may encounter. Often times, water is also used to dilute spills reduce vapors. Since some chemicals react poorly to water and could potentially cause explosions, spread fires, or create a more toxic environment, it is necessary to refer to the emergency response and potential hazards sections of the orange, three digit guide section. Vapors must be addressed in a hazardous materials transportation incident and are typically done so by using foams, absorbing or neutralizing agents. Specific materials need to be known so as to not worsen the incident. Once again, the orange section provides technical advice for vapor control. Table
