1. 1. Who signs the certification on the shipping paper stating that a hazardous material is properly classed, described, packaged, marked and labeled?

   • A. The driver who picks up the load
   • B. The state agency that issued the endorsement
   • C. The shipper who offers the material
   • D. The consignee who receives the load
   Vis svar og forklaring

   Svar: C. The shipper who offers the material

   The shipper classifies the material, chooses the proper shipping name, packages it, marks and labels the packages and signs the certification on the paper. The carrier is responsible for the vehicle, the placards and safe transport, and the driver has to refuse a package that is leaking or a paper that does not match the freight. All three share the job, but the certification is the shipper's word.

2. 2. In the hazardous materials table, which column tells you the hazard class or division of a material?

   • A. Column 1
   • B. Column 3
   • C. Column 5
   • D. Column 8
   Vis svar og forklaring

   Svar: B. Column 3

   Column 1 holds the symbols, Column 2 is the proper shipping name, Column 3 is the hazard class or division, Column 4 is the identification number and Column 5 is the packing group. Reading across a row in that order is how you build a correct shipping description. Names printed in italics in Column 2 are not proper shipping names, so never copy one onto a paper.

3. 3. A four inch diamond attached to a package, rather than to the vehicle, is called:

   • A. A placard
   • B. A marking
   • C. An orange panel
   • D. A label
   Vis svar og forklaring

   Svar: D. A label

   Labels go on packages and are about four inches on a side. Placards go on the vehicle or on a bulk package, are much larger at around ten and three quarter inches, and are what a responder reads from a distance. Markings are a third thing again: the printed words and numbers on the package itself, usually the proper shipping name and the identification number.

4. 4. You step out of the truck at a fuel island. Where do the hazmat shipping papers have to be?

   • A. Folded in your wallet so they stay with you
   • B. In a holder mounted inside the driver's door, or on the driver's seat
   • C. Locked in the trailer with the freight
   • D. Anywhere in the cab, as long as you can find them
   Vis svar og forklaring

   Svar: B. In a holder mounted inside the driver's door, or on the driver's seat

   When you are away from the controls the papers must be in the driver's door holder or lying on the driver's seat, so anyone who opens that door finds them at once. When you are behind the wheel with the belt on, they must be within your immediate reach and either visible to a person stepping into the cab or in that same door holder. They also have to be tabbed or sitting on top of your other paperwork so nobody has to dig.

5. 5. When a load requires placards, how many go on the vehicle and where?

   • A. One, on the rear
   • B. Two, one on each side
   • C. Four, one on each side and one on each end
   • D. Six, three on each side
   Vis svar og forklaring

   Svar: C. Four, one on each side and one on each end

   Placards go on each side and each end, which is four on a single vehicle, so the load can be identified from any direction. They have to be readable, kept clear of other markings that could be confused with them, and fastened so they will not blow off. If the trailer has placard boards, that is where they belong.

6. 6. A crash involving your placarded load sends a bystander to the hospital because of the material. Who must be called, and how soon?

   • A. The National Response Center, as soon as practical and no later than 12 hours
   • B. The shipper only, within 30 days
   • C. Your dispatcher only, at the end of the shift
   • D. Nobody, as long as a written report is mailed later
   Vis svar og forklaring

   Svar: A. The National Response Center, as soon as practical and no later than 12 hours

   Certain incidents trigger an immediate telephone report to the National Response Center at 800-424-8802, including a death, a hospital admission caused by the material, an evacuation lasting an hour or more, or a major road closed for an hour or more. That call does not replace the written report that follows it. Your first job on scene is still to keep people back, warn them of the danger, and hand responders the shipping papers and the emergency response information that goes with them.

7. 7. A placarded vehicle counts as attended when the person in charge is:

   • A. Somewhere on the same property
   • B. Asleep in the sleeper berth of the same truck
   • C. Within a mile and reachable by phone
   • D. Within 100 feet of the vehicle with an unobstructed view of it, awake and out of the sleeper berth
   Vis svar og forklaring

   Svar: D. Within 100 feet of the vehicle with an unobstructed view of it, awake and out of the sleeper berth

   Attending means you can actually see the vehicle and do something about it, which is why the rule is 100 feet, a clear line of sight, awake and out of the bunk. A vehicle carrying Division 1.1, 1.2 or 1.3 explosives must be attended at all times unless it sits in an approved safe haven or on carrier, shipper or consignee property. Other placarded loads must be attended whenever they are parked on a public street, highway or shoulder.

8. 8. How does a placarded vehicle have to handle a railroad grade crossing?

   • A. Stop between 15 and 50 feet from the nearest rail, look and listen, then cross without changing gears
   • B. Slow to 15 miles per hour and cross without stopping
   • C. Stop within 5 feet of the nearest rail so you can see down the track
   • D. No stop is needed if the crossing has lights and gates
   Vis svar og forklaring

   Svar: A. Stop between 15 and 50 feet from the nearest rail, look and listen, then cross without changing gears

   The stop has to be close enough to see down the track but far enough back to survive a mistake, which is where the 15 to 50 foot window comes from. Pick your gear before you start across and stay in it, because a missed shift on the rails is how vehicles get stranded. A stop is not required at an exempt or industrial switching crossing, or when an officer or a green traffic signal is moving you through.

9. 9. Before a state can issue or renew a hazmat endorsement, the driver must:

   • A. Hold a CDL for at least five years
   • B. Clear a TSA security threat assessment, including fingerprints, and pass the hazmat knowledge test
   • C. Get written permission from every shipper on the route
   • D. Pass a skills test in a placarded tank vehicle
   Vis svar og forklaring

   Svar: B. Clear a TSA security threat assessment, including fingerprints, and pass the hazmat knowledge test

   A state may not issue or renew the H endorsement until TSA returns a Determination of No Security Threat, and the knowledge test has to be passed again at renewal. The threat assessment runs on a renewal cycle that cannot exceed five years, and it does not simply follow you around: if you move your CDL to a new state, that state honors the time left from the old assessment and then requires a fresh one. A first time hazmat applicant must also complete entry level driver training from a registered provider before taking the knowledge test.

10. 10. Which of these hazard class numbers are matched with the right kind of material?

    Vælg alle, der passer.

    • A. Class 1 is explosives
    • B. Class 4 is radioactive material
    • C. Class 7 is corrosives
    • D. Class 8 is corrosives
    • E. Class 5 is oxidizers and organic peroxides
    • F. Class 6 is miscellaneous hazardous materials
    Vis svar og forklaring

    Svar: A. Class 1 is explosives, D. Class 8 is corrosives, E. Class 5 is oxidizers and organic peroxides

    The nine classes run in order: 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids and materials that ignite on their own or react with water, 5 oxidizers and organic peroxides, 6 poisons and infectious substances, 7 radioactive, 8 corrosives, 9 miscellaneous. Learn them as a numbered list, because the table, the labels, the placards and the segregation rules all key off the same numbers. Class 9 is the catch all for materials that are regulated but do not fit any of the other eight.

11. 11. Which of these require placards no matter how small the amount on board?

    Vælg alle, der passer.

    • A. Division 1.2 explosives
    • B. Class 3 flammable liquids
    • C. Division 2.3 poison gas
    • D. Division 4.3 dangerous when wet
    • E. Class 8 corrosives
    • F. Class 9 miscellaneous hazardous materials
    Vis svar og forklaring

    Svar: A. Division 1.2 explosives, C. Division 2.3 poison gas, D. Division 4.3 dangerous when wet

    The placarding rules split materials into two tables. Table 1 holds the categories treated as most dangerous, including Divisions 1.1, 1.2 and 1.3, poison gas, dangerous when wet, temperature controlled organic peroxide type B, materials poisonous by inhalation and Radioactive Yellow III, and any amount of them calls for placards. Table 2 covers everything else and only triggers placards at 1,001 pounds or more. The Class 9 placard is not required at all for transportation inside the United States, although a bulk package still has to show its identification number.

12. 12. Which of the following are required when you load or unload a placarded vehicle?

    Vælg alle, der passer.

    • A. Nobody may smoke or carry a lighted cigarette within 25 feet of a vehicle carrying explosives, oxidizers, flammable gas, flammable liquid or flammable solids
    • B. The engine must be shut off while Class 1 explosives are loaded or unloaded
    • C. Packages must be braced so they cannot shift, fall or be damaged while the vehicle moves
    • D. A leaking package may be loaded as long as it goes at the rear of the trailer where you can watch it
    • E. A package bearing a POISON label may ride beside cartons of food as long as nothing is stacked on the food
    Vis svar og forklaring

    Svar: A. Nobody may smoke or carry a lighted cigarette within 25 feet of a vehicle carrying explosives, oxidizers, flammable gas, flammable liquid or flammable solids, B. The engine must be shut off while Class 1 explosives are loaded or unloaded, C. Packages must be braced so they cannot shift, fall or be damaged while the vehicle moves

    Ignition sources and hazmat do not mix, which is what the 25 foot smoking rule and the engine off rule for explosives are both about. Securing the load is more than cargo care here, because a package that slides and splits turns a routine trip into a spill. You never accept a leaking package, and poison labeled packages may not travel with food or animal feed unless they are packaged and overpacked exactly the way the segregation rules allow.

13. 13. Complete the sentence.

    On a shipping paper the basic description must run as one unbroken sequence with nothing mixed in: _____, then the proper shipping name, then the hazard class or division, then the packing group.

    Muligheder for felt 1: the identification number, the total quantity, the emergency response telephone number, the shipper certification

    Vis svar og forklaring

    Svar: the identification number

    Under the current rules the identification number comes first, so a description reads like UN1203, Gasoline, 3, PG II. Older study guides put the proper shipping name first, which is a good reason to work from a current manual rather than one that has been in the truck for a decade. Quantity, the emergency response phone number and the shipper certification all belong on the paper too, but they sit outside the basic description, not inside it.

14. 14. Complete the sentence.

    Materials in Table 2 of the placarding rules only require placards once the vehicle carries _____ or more aggregate gross weight of them.

    Muligheder for felt 1: 454 pounds, 1,001 pounds, 2,205 pounds, 10,001 pounds

    Vis svar og forklaring

    Svar: 1,001 pounds

    1,001 pounds is 454 kilograms, and it is the combined gross weight of all Table 2 hazmat on board including the packaging, not the weight of one product. When two or more Table 2 categories are aboard you may use a single DANGEROUS placard instead of separate ones, but if 2,205 pounds or more of one category is loaded at one facility, that category gets its own placard. Bulk packages and materials with their own placarding rules sit outside this exception.

15. 15. Complete the sentence.

    A vehicle carrying Division 1.1, 1.2 or 1.3 explosives must not be parked within _____ of a bridge, tunnel, dwelling or a place where people work or gather, except for brief periods when the job leaves no other choice.

    Muligheder for felt 1: 50 feet, 100 feet, 300 feet, half a mile

    Vis svar og forklaring

    Svar: 300 feet

    The 300 foot rule is about blast radius, so it applies to explosives rather than to placarded loads in general. Any hazmat load, explosive or not, must also stay at least 5 feet off the traveled portion of a public street or highway except for brief stops the job requires. Parking explosives on private property takes the knowledge and consent of whoever is in charge of that property, and they have to know what you are carrying.

Hvad hazmat-påtegningen bliver testet i

Hazmat-påtegningen, H'et på dit CDL, er ikke et selvstændigt kørekort. Du lægger den oveni et commercial driver's license, du allerede har eller søger om, og det kræver to ting: en teoriprøve og en sikkerhedsgodkendelse. Godkendelsen er en TSA security threat assessment med fingeraftryk og baggrundstjek, og din delstat kan ikke udstede eller forny påtegningen, før TSA melder tilbage med en Determination of No Security Threat. Siden februar 2022 skal en førstegangsansøger til hazmat også gennemføre entry level driver training hos en udbyder på det føderale Training Provider Registry, før teoriprøven kan tages. Gebyret, antallet af spørgsmål, beståelsesgrænsen og hvor hurtigt du kan gå om fastsættes af din delstat, så de eneste tal, der er værd at stole på, er dem i din egen delstats CDL-manual.

Selve stoffet er føderalt. Det kommer fra reglerne om farligt gods i 49 CFR parts 100 til 185, som er offentlige og gratis at læse. Forvent spørgsmål om, hvad der gør et materiale farligt, og hvem der har ansvaret for hvad, hvordan man læser the hazardous materials table, de ni fareklasser, hvad der skal stå på en shipping paper og hvor det papir skal ligge, hvornår der kræves placards og hvor mange, labels og markeringer på kolli, regler for læsning og adskillelse, opsyn og parkering, køreregler som jernbaneoverskæringer og rute- og tunnelbegrænsninger, hvad du gør ved en hændelse, og den security plan og security awareness training, din arbejdsgiver skal sørge for.

Hazmat-reglerne ændrer sig. Parts 100 til 185 bliver revideret jævnligt, og detaljer, der før stod i hver eneste studievejledning, er siden skrevet om, blandt andet rækkefølgen på grundbeskrivelsen på en shipping paper. Læs den aktuelle CDL-manual, din delstat udgiver, og når et tal virkelig betyder noget, så tjek det mod den gældende regel frem for mod en håndbog, der har kørt rundt i lastbilen i årevis. Hvert tal på denne side blev kontrolleret mod reglerne, da siden blev skrevet, men du er selv ansvarlig for den udgave, der gælder den dag du går til prøve, og den dag du kører.

Sådan bruger du smagsprøven

De her 15 spørgsmål går efter begrundelsen bag reglerne frem for ren udenadslære. De spørger, hvorfor dine shipping papers ligger i lommen i døren, hvorfor rygeforbuddet måles i feet, hvorfor et Table 1-materiale kræver placards uanset vægt, mens et Table 2-materiale ikke gør, og hvad dit første træk er ved et uheld. Hazmat ligner en bunke usammenhængende tal, indtil du ser logikken under den, og når du gør, holder det meste af bunken op med at skulle terpes. Reglen om 300 feet er en sprængradius. Rygereglen om 25 feet er en antændelsesafstand. Lommen i døren er det første sted, en brandmand kigger. En regel, du kan forklare, er en regel, du stadig har den dag, en havnearbejder rækker dig et papir, der ikke passer med det, der bliver læsset på traileren.

Tag den i ét stræk uden en bog åben, og læs så hver eneste forklaring, også dem du svarede rigtigt på. Behandl et forkert svar som et emne frem for et faktum. Missede du spørgsmålet om placards og spørgsmålet om 1.001 pounds, så repeter de to placarding-tabeller side om side, for de er én idé set fra to vinkler. Missede du spørgsmålene om shipping papers, så sæt dig ud i en lastbil og læg papirerne, hvor de hører til, indtil det sidder i rygmarven frem for at være noget, du remser op. De områder, der oftest fælder folk, er grænserne for placards, reglerne om adskillelse og skellet mellem, hvad afsenderen skylder dig, og hvad du skylder afsenderen, så giv dem en ekstra omgang.

Den her smagsprøve dækker kun hazmat, så den er ikke en hel læseplan. Hazmat-teoriprøven er en af flere, du kan få brug for, og general knowledge-prøven kræves til hvert eneste CDL, så kør søsterquizzerne nedenfor og sammenlign, hvor du taber point. Læs også de dele, smagsprøven ikke tester, blandt andet rute- og tunnelbegrænsninger, det dæktjek du skylder ved turens start og hver gang du parkerer, cargo heaters, og den security plan og security awareness training, din arbejdsgiver skal sørge for. Intet på denne side er et rigtigt eksamensspørgsmål, og ingen øveprøve kan love dig en bestået prøve. Det, en smagsprøve kan, er at fortælle dig, hvilket kapitel du skal åbne som det næste.

Sådan bygger StudyPDF fulde øveprøver ud fra dit eget materiale

Femten spørgsmål kan finde dine svage punkter. De kan ikke gøre dig klar alene, og en generisk hazmat-spørgsmålsbank rammer ikke det, din delstats CDL-manual eller dit vognmandsfirmas eget kursusmateriale lægger vægt på. Hazmat flytter sig også. Reglerne bliver revideret jævnligt, og en spørgsmålsbank skrevet for år tilbage kan stille og roligt lære dig noget, der er holdt op med at være rigtigt, og det betyder mere her end på de fleste andre prøver, for et forkert svar om en placard bliver ikke på papiret. Det sikreste at læse i er det aktuelle dokument, du faktisk har fået udleveret, og den sikreste måde at øve på er at blive testet i det dokument frem for i en andens sammendrag af det.

StudyPDF arbejder ud fra dit materiale i stedet. Du uploader hazmat-afsnittet af din delstats CDL-manual, dit firmas hazmat-kursusmateriale eller de sider af 49 CFR, din underviser har givet for, og Bo, studieagenten, bygger fulde øveprøver ud fra præcis de sider. Hvert spørgsmål bygger på det, du har uploadet, og hver forklaring peger tilbage på den side, det kom fra, så når et svar ser forkert ud, kan du tjekke kilden på få sekunder i stedet for at skændes med en sort boks. Du kan lave en ny prøve så tit du vil og holde en enkelt på ét område som placards eller adskillelse, og Bo holder styr på, hvilke emner du bliver ved med at ramme forkert, så næste omgang starter der, hvor du er svagest, i stedet for forrest i bogen.

Du behøver ikke et dokument for at begynde. Har du ikke noget at uploade, så nævn et emne i stedet, for eksempel regler for placards, de ni fareklasser eller hvad der hører til på en shipping paper, så skriver Bo en øveprøve ud fra det. Det er den hurtigere vej ind, hvis du stadig venter på en manual, eller du bare vil se, om formatet passer dig, og du kan lægge dine egne filer til bagefter og have det hele i samme fag. Flashcards, en studieguide og et resumé kommer ud af det samme materiale, hvis du hellere vil læse, før du bliver testet. Gratis at komme i gang.
