Pennsylvania CDL HazMat flashcards

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

Hazardous Materials Table

49 CFR 172.101 table listing each HazMat by proper shipping name with hazard class, UN number, packing group, labels, and required packaging. It controls how a material must be described and shipped.

Basic description order

Proper shipping name, hazard class or division, UN/NA identification number, and packing group, in that order, on the shipping paper. The packing group is omitted when none is assigned.

Packing Group I

The highest hazard packing group, indicating greatest danger within a class. It drives stricter packaging, and for Division 6.1 liquids it triggers poison inhalation hazard handling.

Forbidden materials

Materials that may not be offered or transported in commerce under the regulations. A material not listed by name must use a generic or n.o.s. entry with its technical name.

Emergency response telephone

A number on the shipping paper that is monitored at all times during transportation and reaches a person with emergency response information. An answering machine or call-back number does not satisfy the requirement.

Shipping paper accessibility

The driver keeps HazMat shipping papers within reach while at the controls and in a pouch or holder when away from the vehicle. They must be presented on demand to enforcement or responders.

Shipping paper retention

Shippers and carriers retain HazMat shipping papers for 2 years. Shippers of hazardous waste retain them for 3 years.

Emergency response information

Information accompanying the shipping paper describing the hazard nature, fire and explosion risks, immediate precautions, first aid, and handling methods. It may be a separate guide or the ERG.

Placarding threshold

Table 2 materials require placards when the aggregate gross weight in one vehicle reaches 1,001 lb (454 kg). Table 1 materials require placards for any quantity.

Table 1 materials

Materials requiring placards for any quantity, including Division 1.1-1.3 explosives, Division 2.3 toxic gas, Division 4.3 dangerous when wet, Division 6.1 PG I PIH, and Radioactive Yellow-III.

DANGEROUS placard use

A substitute placard for Table 2 materials when the aggregate weight is under 1,001 lb but placarding is still required. It may not be used when Table 1 materials are present.

UN number on placard

Bulk packages, portable tanks, and tank cars must display the UN number on the placard or on an adjacent orange panel. Non-bulk vehicle placards do not require the number.

PIH segregation rule

Division 6.1 PG I poison inhalation hazard materials and Division 2.3 toxic gases must not be loaded in the same vehicle with food, feed, or anything intended for human or animal consumption.

Acid and cyanide rule

Cyanides and acids must never be loaded together because mixing can release deadly hydrogen cyanide gas. Oxidizers are also kept apart from flammable and combustible materials.

Load securement check

Blocking, bracing, and tiedowns must prevent packages from sliding, rolling, or tipping. Check tiedown tension after the first miles and at each stop.

Explosives loading separation

Detonators and initiating devices are separated from explosive charges. Division 1.1 and 1.2 materials are not loaded with incompatible explosives, and the load must not shift.

Bulk package definition

A package holding more than 119 gallons of liquid, more than 882 lb of solid, or more than 1,000 lb of gas, or any cargo tank or portable tank regardless of capacity.

Cargo tank inspection

Cargo tanks must meet their specification with periodic external visual, leak, internal, and pressure tests. Before loading, the driver checks for leaks, cracks, and damaged fittings.

Static bonding and grounding

Tank vehicles loading flammable liquids must be bonded and grounded to prevent static ignition. Dome covers are closed and secured before the vehicle moves.

Residue marking

An empty but unpurged tank keeps its placards and shipping papers marked RESIDUE: Last Contained, so responders know the prior contents and hazard.

Railroad crossing stop

A vehicle carrying a HazMat requiring placards must stop at every railroad crossing, stop the engine, look and listen, and proceed only when safe, whether or not a train is visible.

HazMat parking distance

Do not park a placarded vehicle within 5 feet of the traveled portion of a public street or highway, or within 300 feet of a bridge, tunnel, dwelling, or place of public assembly unless attended.

Unattended placarded vehicle

A placarded vehicle may be left unattended only in a secure location or when the driver is within 100 feet and the vehicle is visible. Otherwise it must be attended.

Smoking distance

Smoking and open flames are prohibited within 25 feet of a placarded vehicle during loading, unloading, or while stopped. No smoking in the cab or near the cargo.

Reportable quantity

A release equal to or greater than the RQ listed in 49 CFR 172.101 Appendix A must be reported immediately to the National Response Center at 1-800-424-8802.

DOT Form 5800.1

The written incident report submitted to DOT within 30 days for a release causing death, hospitalization, evacuation, property damage over $50,000, or a reportable quantity release.

Initial incident actions

Stop, protect yourself, isolate the area, keep people away and upwind, notify responders, and do not attempt cleanup unless trained and equipped. Prevent spills from entering drains.

Water-reactive fire rule

For Division 4.3 dangerous when wet materials, do not use water. Use the extinguishing agent specified in the emergency response information or ERG guide for the material.

Explosives placarding

Any quantity of Division 1.1, 1.2, or 1.3 requires placards. Division 1.4 requires placarding only when the aggregate gross weight reaches 1,001 lb.

Radioactive Yellow-III

A Class 7 label category requiring vehicle placards for any quantity. Radioactive packages are loaded within transport index limits and kept away from food and feed.

Hazardous waste manifest

The Uniform Hazardous Waste Manifest accompanies the shipment and is signed by generator, transporter, and designated facility. The transporter retains a copy for 3 years.

PIH any-quantity placard

Division 6.1 PG I and Division 2.3 materials require placards for any quantity. They are kept away from food, feed, and consumer goods, and the PIH designation is noted for responders.
