Hazmat Study Guide
The shipper is responsible for packing, labeling, and preparing the hazardous materials shipping papers for a common carrier.
Never use hooked or other metal tools when handling packages of explosives.
The driver is responsible for finding out what permits or special routes will be needed to haul hazardous materials.
The hazard class of a two-liter bottle of material is “Flammable Liquid”. If the descriptor also says “Poison Inhalation Hazard”, you should placard the vehicle with both the “Poison” and “Hazard” class placard.
When you are hauling hazardous material, you must stop at least 15 feet, but no more than 50 feet from the nearest track.
After you have loaded hazardous material into a cargo tank, you must close all manholes and valves and be sure they are free of leaks before moving the vehicle.
If there is an “RQ” before OR after the item description on the shipping paper, it means the carrier must report a spill of this material.
Class A explosives must not be transported in a combination vehicle if it includes a placarded cargo tank.
The basic description of a hazardous material includes the hazard class, the identification number, and the proper shipping name. The order they must appear on the document is:
Proper shipping name
While transporting Class A or B explosives, the driver must have in their possession the written route plan.
When hauling hazardous materials, you must stop the vehicle and check any dual tires at least once every 2 hours or 100 miles, whichever is less.
An “X” in the “HM” column of the shipping paper entry means that the entry is for a hazardous material.
If a vehicle contains 500 pounds each of explosives A and B, you must use “Explosives A” placards.
You will need to use at least 4 placards for a vehicle carrying hazardous materials.
When you are not behind the wheel while carrying hazardous materials, the shipping papers must be on the driver’s seat or in the door pouch.
If you need to warn of a stopped vehicle which has a tank used for flammable liquids or gases, you may use reflective triangles.
The driver is responsible for checking that the shipper correctly named, labeled, and marked a hazardous materials shipment.
When fueling a placarded vehicle, someone must always be at the nozzle, controlling the fuel flow.
When transporting chlorine in cargo tanks, you must have both an approved gas mask and an emergency kit for controlling leaks in fittings on the domecover plate.
When shippers package hazardous materials, they must certify that the job was done according to the regulations. The only exception is when the shipper is a private carrier carrying their own product.
Before loading or unloading any explosive, check the cargo space for:
a cargo heater that could start
sharp points that might damage the cargo
loose floor boards or plates
The total transport index of all radioactive materials packages in a single vehicle must not exceed 50.
If you are hauling hazardous materials and you find that one of your tires is leaking, you must stop at the nearest place and fix it.
If you are in an accident involving hazardous materials, you should keep all people far away and upwind of the accident.
The intent of the hazardous materials regulations has three parts, to:
To ensure safe drivers and equipment
To contain the material
To communicate the risk
You find an overheated tire during an enroute inspection. If you are hauling hazardous materials, you must remove the tire and place it a safe distance from the vehicle.
Carriers must give each driver who transports Class A or B explosives a copy of FMCSR Part 397.
If the word “Forbidden” appears in the hazard class column of an entry in the hazardous materials table, a common carrier must never transport the material.
You have a vehicle without racks to hold cylinders of compressed gas. You may load such cylinders only if they are loaded upright or braced laying down flat.
Whenever your vehicle is placarded, do not drive near open fire unless you can safely pass the fire without stopping.
When you are behind the wheel of a truck carrying a hazardous material shipment, the shipping papers must be in a pouch on the driver’s door or in clear view within your reach.
The power unit of a placarded vehicle must have a fire extinguisher with a CL rating of 10B:C or more.
To find out if a shipment includes a hazardous material, you should look at the shipping paper.
You may not park a vehicle carrying hazardous materials within 300 feet of an open fire.
You must briefly leave your placarded vehicle (no explosives) on a public roadway. The person who watches your vehicle should be:
Awake and able to move the vehicle if needed
Someone who knows what to do in an emergency
On the vehicle or within 100 feet of the vehicle and have it within clear view
A properly prepared uniform hazardous waste manifest must be signed and carried by anyone transporting a hazardous waste.
A driver who transports route controlled radioactive material must have had special training by the carrier within the last 2 years.
A dated certificate of radioactive materials training must be carried by the driver.
Your vehicle contains explosives, oxidizers, or flammables. No one may smoke within 25 feet of the vehicles.
You are going to be hauling hazardous materials over a route you do not know well. You should check the route and the permits needed for the trip before starting the trip.
Cylinders containing compressed gases may only be loaded onto a vehicle if the cylinders are:
Loaded in an upright or horizontal position
Loaded into racks attached to the vehicle
In boxes that will keep them from turning over
No one may smoke around any vehicle being loaded or unloaded with flammables, oxidizers, or explosives.
You have hazardous material leaking from a container but not spilling from the vehicle. Drive to the closes area where you can get help and call emergency personnel if they are needed.
The transport index of a radioactive material tells the degree of control needed during transportation.
Animals and human foodstuffs should not be loaded in the same vehicle with poisons.
When there is a hazardous materials emergency, you should:
Keep people away
Prevent smoking and keep open flame away
Warn others of the danger
A hazard class name or ID number may not be used to describe a non-hazardous material.
With most hazardous material, you may park within 5 feet of the road briefly. If your work requires it, the materials which are the exception and do not allow parking this close to the road are explosives A and B.
The driver is responsible for safely transporting a hazardous material shipment without delay and keeping the shipping papers in the right place.
There are two lists that drivers, shippers, and carriers use to find out if a material is a regulated product:
List of hazardous substances and reportable quantities
Hazardous materials table
You should stop before crossing a railroad grade if your vehicle is carrying any amount of chlorine.
If hazardous material is spilling from your vehicle, do not move your vehicle any more than safety requires.
A vehicle carrying explosives has crashed with another vehicle. You should not pull them apart until the explosives have been placed at least 200 feet away from the vehicles and occupied buildings.
