Have you ever wondered as you drive down the highway about those trains you see rolling along, and what on earth could be in all those cars? You also see lots of graffiti, done by some local “artists” along the way, and can’t help but question all the places that train has been. One thing you need to understand, is that many of those cars are carrying hazardous materials, and in the event of a derailment, or spill, you need to drive away from the area as soon as possible.
Railroad companies are overseen primarily by the Federal Railroad Administration, but also answer to the Department of Transportation, and the National Transportation Safety Board. No person may transport a hazardous material in commerce unless that material is properly classed, described, packaged, marked, labeled, and placarded and is in condition for transportation according to DOT regulations. Railroad Company computers are able to track the trains at all times.
For your information, here are the hazard classes and divisions:
1 – Explosives (1.1 – Explosive with mass explosion hazard; 1.2 – Explosive with projection hazard; 1.3 – Explosive with predominantly fire hazard; 1.4 – Explosive with no significant blast hazard; 1.5 – Very insensitive explosive; blasting agent, and 1.6 – Extremely insensitive detonating substance.)
2. – Gases (2.1 – Flammable gas; 2.2 – Nonflammable, nonpoisonous, (nontoxic), compressed gas; and 2.3 – Poisonous (toxic) gas (by inhalation).
3 – Flammable Liquids
4 – Flammable Solids and Reactive Solids/Liquids (4.1 – Flammable solid; 4.2 – Spontaneously combustible material, and 4.3 – Dangerous when wet marked.)
5 – Oxidizers and Organic Peroxides (5.1 – Oxidizer; 5.2 Organic peroxide.)
6 – Poisonous (Toxic) Materials/Infectious Substances (6.1 – Poisonous (Toxic) material; 6.2 – Infectious substance.
7 – Radioactive Materials
8 – Corrosive Materials
9 – Miscellaneous Hazardous Materials
Worded Classes
Combustible Liquids (regulated in bulk packaging only)
ORM-D (Other Regulated Materials – D) (regulated in air transportation only; not regulated in rail transportation.
Shipping hazardous materials are time-sensitive. Those under a 20-day time limit to arrive are:
1. Ethylene, refrigerated liquid
2. Hydrogen, refrigerated liquid
3. Chloroprene, stabilized
4. Flammable liquid, N.O.S.
5. Hydrogen chloride, refrigerated liquid
6. Vinyl fluoride, stabilized
Those having a 30-day shipping limit are:
Styrene monomer, inhibited
Flammable Liquid, (Recycled styrene)
When transporting hazardous material shipments in a train, a member of the train crew must also have acceptable emergency response information and a document showing the current position of each hazardous material in the train. This documentation provides railroad and emergency response personnel with accurate information for every hazardous material being transported.
Next, we will talk about what type of training railroad crews experience to be prepared for a hazardous material spill caused by a railroad derailment or railroad car leak.
Occasionally, we hear about a train derailment, or the spill of a hazardous material from a train car. Today, we will share typical instructions that are given to railroad personnel in case of such an occurrence. First, the train crew should notify the train dispatcher of such a derailment and the location where the train crew will meet the emergency response personnel.
SAFETY IS OF THE MOST IMPORTANCE. (THIS MEANS SAFETY TO YOU, THE OTHER EMERGENCY RESPONSE PERSONNEL AND THE PUBLIC.) THE FIRE CHIEF IS IN COMMAND – DO NOTHING WITHOUT HIS AUTHORITY.
As earlier mentioned, railroad authorities notify train personnel of such a derailment and the location of their crew. At the time the railroad company notifies the 911 dispatcher of a hazardous spill, the dispatcher must ask the railroad the location of the train conductor, who will have all the shipping papers in his possession.
Know what you are dealing with first; do not get over anxious and go into an area with a derailed car that has hazardous material leaking. Take note of the wind direction and which area should be evacuated first, should an evacuation be necessary. Establish a command center at this point and notify all people involved with this incident of its location. The evacuation should be handled by the local Police Department.
It is the primary job of the railroad personnel to protect the public from fumes, fire or possible explosion that may occur from a hazardous material spill. At some point the fire chief will determine if outside help (county, state, federal) is needed and notify the mayor to start the phone calls for assistance. Containment and blockades will be the responsibility of the public works department.
The spill area belongs to the emergency response personnel under the supervision of the fire chief until the proper hazardous material personnel arrive on the scene to take over. The fire chief still remains in command of the area until such time as he and other specialists consider it safe. Railroad personnel are highly trained and equipped for these situations, and should keep thing under control.
If EMS personnel and ambulances are not immediately needed, they should wait in the immediate area of the command center and at the fire chief’s disposal. Railroad company personnel should be equipped with the proper PPE (personal protective equipment) to ensure compliance with all safety requirements, as well as protection for their safety.
In the event of an accident involving a train, there is no place for onlookers. Keep a safe distance away, or find another route.
