Virginia CDL HazMat flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Hazardous material

A substance or material that DOT determines is capable of posing an unreasonable risk to health, safety, and property when transported in commerce, and that is listed in the Hazardous Materials Table.

Hazard class 3

Flammable and combustible liquids. Class 3 covers liquids with a flash point of not more than 60 degrees C (140 degrees F), such as gasoline, diesel fuel, and acetone.

Packing group

A ranking of hazardous materials by degree of danger: Packing Group I is great danger, Packing Group II is moderate danger, and Packing Group III is minor danger.

HazMat employee

A person who directly affects hazardous materials transportation safety, such as a driver, loader, or packager, or anyone who marks, labels, placards, prepares shipping papers, or tests packaging.

Basic description order

Proper shipping name first, then hazard class or division, then UN or NA identification number, then packing group, for example 'Gasoline, 3, UN1203, PG II'.

Emergency response telephone

A 24-hour number on the shipping paper that is monitored at all times the shipment is in transit and answered by a person who knows the hazards and response information.

Placard size and placement

Placards are 10.75-inch diamonds that show the hazard class and identification number, mounted on the front, rear, and both sides of the vehicle or bulk package.

Placarding threshold

Placards are required for any quantity of a Table 1 material and for 1,001 pounds or more aggregate gross weight of a Table 2 material loaded in one vehicle.

Smoking distance from vehicle

Do not smoke or carry lighted smoking material within 25 feet of a vehicle that contains explosives, oxidizers, or flammable materials during loading, unloading, or transport.

Segregation rule for poisons

Division 6.1 poisonous materials must never be loaded in the same vehicle with food intended for human or animal consumption.

Cyanide and acid separation

Cyanide salts and acids must be kept apart so a leak from one container cannot mix with the other and produce deadly hydrogen cyanide gas.

Securing the load

Packages must be braced, blocked, or tied down so they cannot slide, shift, or fall during transport, without covering required labels, markings, or placards.

Tank endorsement threshold

The N endorsement is required when the vehicle carries liquids or gases in tanks of 119 gallons or more each, with an aggregate capacity of 1,000 gallons or more.

Outage

The empty space left above the liquid in a cargo tank so the product can expand as temperature rises; filling beyond the outage limit causes overflow or tank damage.

Liquid surge

The forward and backward movement of liquid in a partly filled, unbaffled tank, which can push a vehicle past a stop line and increases rollover risk on curves.

Non-bulk package limits

A non-bulk package holds 119 gallons or less of liquid, 882 pounds or less of solid, or has 1,000 pounds or less water capacity when holding a gas.

Railroad crossing stop rule

Any vehicle required to be placarded must come to a complete stop before every railroad crossing, look both ways, and proceed only when the track is clear.

HazMat parking distance

Park off the traveled portion of the road at least 5 feet from the edge, and stay 300 feet from bridges, tunnels, and occupied buildings when carrying explosives or flammables.

Tire check interval

Tires should be checked at least every 2 hours or 100 miles; underinflation and heat build-up are the leading causes of tire fires on hazardous materials loads.

HazMat route selection

Hazmat drivers use routes that avoid congested areas, tunnels, and heavily populated zones, and that follow posted designated hazardous materials routes where they exist.

National Response Center

The federal point of contact, reached at 1-800-424-8802, that must be notified immediately when a hazardous materials release, fire, or serious accident occurs in transportation.

DOT reportable incident

An incident involving a death, an injury requiring hospitalization, property damage over $50,000, an evacuation, closure of a major transport artery, or a release of hazardous material.

Written incident report deadline

DOT Form 5800.1, the written hazardous materials incident report, must be submitted to the agency within 30 days of the incident.

Emergency Response Guidebook

A reference carried with hazmat shipments; look up the material by ID number in the yellow pages or by name in the blue pages, then follow the orange guide page.

Training within 90 days

A new hazmat employee must complete required training within 90 days of employment and may perform hazmat duties only under direct supervision until that training is complete.

Recurrent training interval

Hazmat employees must be retrained at least every 3 years, and the employer must keep a training record documenting the dates and content for each employee.

Security plan triggers

A security plan is required for high-consequence loads such as Division 1.1-1.3, 2.1, 2.3, 3 PG I, 4.2, 4.3, 6.1 PG I, and highway route controlled Class 7.

Security awareness

Training that teaches a hazmat employee to recognize and respond to possible security threats, such as suspicious people, tampering, or unusual questions about the load.

TSA security threat assessment

A fingerprint-based federal background check required before a hazmat endorsement is issued or renewed; a favorable assessment stays valid for 5 years.

TSA disqualifying offenses

Terrorism-related convictions, certain felonies within the past 5 years, and any determination that the applicant poses a threat to transportation security bar the hazmat endorsement.

H endorsement eligibility

The applicant must hold a CDL, be at least 21 for interstate driving, have legal presence in the United States, pass the hazmat knowledge test, and clear the TSA check.

Conviction notice to employer

A CDL driver must notify the employer in writing within 30 days of any conviction for a traffic violation other than a parking violation.
