Cdl Hazmat Test Questions And Answers

› Contain Shippers package hazardous materials in a way that is meant to completely contain the materials. Vehicles should be placarded to communicate the risk of the cargo.

› Once every three years All drivers must be trained in the security risks of hazardous materials transportation. This training must include how to recognize and respond to possible security threats. Hazardous materials employees must be trained and tested at least once every three years.

› The Transportation Security Administration When applying for an original or renewed HazMat endorsement, you must undergo a federal security threat assessment done by the Transportation Security Administration (TSA).

› Refuse it. It is a driver's responsibility to refuse packages or shipments of hazardous materials if they contain leaks

› The risks associated with the material. A hazardous material will be placed into one of nine classes to explain the type of risks associated with the material.

› Place the label on a tag securely attached to the item. Shippers should place applicable diamond-shaped hazard warning labels on hazardous materials packages. If a label will not fit entirely onto a package, shippers may instead place the label on a tag that is securely attached to the package.

› Poison Gas or Poison Inhalation Hazard If the words "Inhalation Hazard" appear on the shipping paper or package, you must display the "Poison Inhalation Hazard" or "Poison Gas" placards, as appropriate.

› Highlighted in a contrasting color. If a shipping paper describes both hazardous and non-hazardous materials, the hazardous materials must be distinguished in one of three ways. They must be entered first on the shipping paper, highlighted in a contrasting color, or properly marked with an "X" in a column titled "HM."

› The shipper's certification When a shipper packages hazardous materials, they certify that the package has been prepared according to Hazardous Materials Regulations (HMR). Unless a package is clearly unsafe or noncomplying with HMR, you may accept the shipper's certification concerning the proper packaging of a material.

› The shipping paper matches the markings and labels on packages. It is always a good idea to compare package markings and labels to accompanying shipping papers. Always make sure the shipper has displayed the correct basic description on the shipping paper and has provided the proper labels on the packages.

› At least three inches away from any other markings. A placard must be placed at least three inches away from any other markings. The placard should be kept clear of attachments or devices, such as doors and ladders. Placards should always be placed against a background of a contrasting color.

The hazard class of the materials. To determine which placards need to be used, you must know the hazard class of the materials being shipped, the amount of hazardous materials being shipped, and the total weight of all hazardous materials in your vehicle.

› Braced to prevent movement during transportation. Containers of hazardous materials should be braced so they will not fall, slide, or bounce around during transportation.

› A heater. The use of cargo heaters is not always permitted. When transporting materials that are categorized as Class 1 (Explosives), Class 2.1 (Flammable Gases), or Class 3 (Flammable Liquids), the use of heaters in the same space is generally prohibited.

› Roll the containers. If loading by hand, load breakable containers of corrosive liquid one by one. Keep them facing upright. Do not drop or roll the containers.

› Parked within 300 feet of a bridge. Except when parking briefly to perform necessary functions for vehicle operation (such as refueling), never park a vehicle carrying Division 1.1, 1.2, or 1.3 explosives within 300 feet of a bridge, tunnel, or building. Never park such a vehicle within five feet of the traveled portion of the road.

› With reflective triangles. If your vehicle breaks down while you are transporting explosives and you need to use warning signals, use reflective triangles or red electric lights. Never use burning signals, such as flares or fuses, when transporting explosives.

› You must have a written route plan. If transporting Division 1.1, 1.2, or 1.3 explosives, you must follow a written route plan. Whenever placarded, avoid heavily populated areas, crowds, tunnels, narrow streets, and alleys. Be sure to research any restrictions that may apply to the routes you plan to take.

› 25 feet You should not smoke within 25 feet of a placarded cargo tank used to transport materials that are categorized as Class 3 (flammable liquids) or Division 2.1 (gases). Do not smoke or carry a lit cigar, pipe, or cigarette near a vehicle containing flammable or explosive materials.

› The engine should be turned off. If you need to refuel a vehicle carrying hazardous materials, you must first turn off the engine. While refueling, someone must be at the nozzle and controlling the fuel flow at all times.

› Allows oxygen into the trailer. When experiencing a cargo fire, it may be a bad idea to open the doors to the trailer. Doing so allows oxygen to enter the area, potentially causing the fire to flare up and expand.

› Using the shipping papers. If you discover a cargo leak while transporting hazardous materials, use the shipping papers, label, or package location to identify which materials are involved. Do not try to touch or smell the leaking materials to determine what they are because doing so could result in injury or death.

› Park the vehicle. If you discover that a cargo of hazardous materials is leaking from your vehicle, you should park the vehicle as soon as possible. The longer you continue driving, the longer the trail of contamination becomes. While this creates potential danger and harm to others, it also increases clean-up expenses.

› On the top of a stack of shipping papers. Carriers and drivers must be able to quickly identify hazardous materials' shipping papers. Shipping papers for hazardous materials should be on the top of a stack of shipping papers.

› Kept on the driver's seat. Shipping papers for hazardous materials should always be easily accessible. When a driver is not in their vehicle, hazardous materials' shipping papers should be left on the driver's seat.

› The indicated substance should not be transported. The third column of the Hazardous Materials Table lists items' hazard classes and divisions. Drivers should never transport a material that is marked by the word "Forbidden."

› Should not be abbreviated on a shipping paper. Identification numbers, shipping names, and hazard classes must never be abbreviated when listed on a shipping paper. The only exception to this is if the abbreviation is specifically authorized in the hazardous materials regulations.

› The technical name of the hazardous material If the letter "G," for "Generic," is written in Column 1 of a shipping paper, the technical name of the associated hazardous material must also be listed.

› An emergency response telephone number. In general, a shipper is required to list an emergency response telephone number on hazardous materials' shipping papers. There are some exceptions to this rule.

› Any risks of fire or explosion. At a minimum, emergency response information must include the basic descriptions and technical names of the materials being transported; immediate hazards to health; risks of fire or explosion; immediate precautions to be taken in the event of an accident or incident; immediate methods for handling fires; initial methods for handling spills or leaks in the absence of fires; and preliminary first aid measures.

› Within 100 feet of the vehicle. A person attending a parked placarded vehicle must be either awake inside the vehicle or they must be within 100 feet of it. If not inside the vehicle itself, the person must have a clear view of the vehicle. The person attending may not be inside the sleeper berth.

› A ground should be established before opening the filling hole. Before loading or unloading a tank with flammable liquids, you should turn off the engine, unless running the engine is necessary to operate a pump. Ground the tank before opening the filling hole and maintain the ground until after closing the filling hole.

› Remove the explosives from the vehicle before separating the vehicles involved in the collision. If you are driving a vehicle that is transporting Class 1 explosives and it is involved in an accident, you should warn others of the danger, keep bystanders away, and not allow smoking or open fires near the vehicle. Before separating the vehicles involved in the collision, remove all explosives and place them at least 200 feet away from the vehicles and any occupied buildings.

› The driver should not operate the vehicle until it has been cleaned. If you are transporting radioactive material and believe there is a leak or broken package in your cargo, you should tell your dispatcher or supervisor as quickly as possible. Do not touch or inhale the material. Do not use the vehicle until it has been cleaned or checked with a survey meter.

› Within reach. While hazardous materials are being transported, shipping papers should either be kept in a pouch in the driver's side door or in another location where the driver is able to easily reach them while their seat belt is fastened. The papers must be clearly visible to anyone who is entering the cab

› You must stop before crossing the tracks. If transporting any amount of chlorine, a driver must always stop at a railroad crossing 15 to 50 feet from the nearest track, regardless of the presence of a train.

› Send someone else for help. If a cargo of hazardous materials begins to leak, do not move your vehicle any more than safety requires. If you continue to drive, an even larger area will become contaminated. Instead, you should park your vehicle, secure it, stay with the vehicle, and contact the proper emergency personnel. If you do not have access to a phone, you should send someone else to get help.

› Must stay within 25 feet of the tank. The loading and unloading of a tank must be watched by a qualified person. They must be alert; have a clear view of the tank; stay within 25 feet of the tank; know the hazards of the materials involved; know the procedures to follow in an emergency; and be authorized and able to move the tank if necessary

› Radiation will pass through to other packages. Radiation surrounds packages of radioactive materials and passes through to other nearby packages. To address this, the number of radioactive packages that can be loaded together is limited.

› Must stop at railroad crossings before proceeding. A vehicle with tanks that are used to transport hazardous materials must always be stopped before being driven over railroad tracks, even if the tanks are empty.

› Are not permanently attached to a vehicle. Cargo tanks remain on a vehicle at all times, regardless of whether or not they are carrying cargo. Portable tanks are bulk packaging and are not permanently attached to a vehicle.

› In the DOT Emergency Response Guide. Information about hazardous chemicals is found in the Emergency Response Guide (ERG) provided by U.S. Department of Transportation (DOT). The ERG is indexed by the proper shipping names and identification numbers of substances.

› Using a tire pressure gauge. You should examine your tires at the beginning of every trip and after every stop to ensure that they are properly inflated. The only acceptable way to check tire pressure is to use a tire pressure gauge.

› A gas mask A driver transporting chlorine in cargo tanks must have an approved gas mask in the vehicle, as well as an emergency kit for controlling leaks in dome cover plate fittings on the cargo tank.

› On the material's packaging. A material's ID number must appear on its accompanying shipping paper as well as on its packaging. It must also appear on cargo tanks and other bulk packaging.

› Made from non-ferrous materials. Use a floor lining when transporting Division 1.1, 1.2, or 1.3 materials. The floors should be tight and the liner must be made from either non-metallic material or non-ferrous metal. Non-ferrous metals are metals that do not contain iron or iron alloys.

› Radioactive Some radioactive materials are required to be accompanied by a transport index. A transport index is a number that indicates how much control the material will require during transport. The total transport index of all cargo in a single vehicle may not exceed 50.

› Before Unless your engine runs a pump for product transfer, turn it off when loading or unloading a compressed gas tank. If you do use your engine to run a pump, you should turn the engine off after the product transfer but before unhooking the hoses.

› 10 B:C. The power unit of a placarded vehicle must be equipped with a fire extinguisher with an Underwriters Laboratories (UL) rating of 10 B:C or more.

› In a safe haven. When transporting hazardous materials, you may leave your vehicle unattended in a safe haven. A safe haven is a location that has been approved for parking unattended vehicles that are loaded with explosives.
