HazMat employee definition

Any person who directly affects hazardous materials transportation safety, including drivers, loaders, and shipping-paper preparers; requires general awareness, function-specific, safety, and security awareness training.

Training frequency requirement

HazMat training must be completed within 90 days of hire and repeated at least every 3 years; the employer must certify and retain training records.

Reportable quantity

The threshold amount of a hazardous substance released into the environment that triggers notification to the National Response Center at 1-800-424-8802.

Shipper responsibility

The shipper classifies the material, selects the proper shipping name, prepares accurate shipping papers, and provides required markings, labels, and placards.

Shipping paper basic description

The proper shipping name, hazard class or division, UN/NA identification number, and packing group, in that order, plus total quantity and number of packages.

Emergency response telephone number

A number monitored at all times during transport that reaches a person with knowledge of the material; prerecorded messages do not satisfy the requirement.

Emergency response information

Information immediately available to the driver covering the nature of the hazard, firefighting and spill response guidance, and first aid measures for the material.

Shipping paper location

Kept within reach of the driver while in the vehicle, in a pouch on the driver's door, or on the driver's seat when out of the vehicle.

Placard placement

Placards are displayed on both sides and both ends of the vehicle; for a trailer, on the front, rear, and both sides.

1,001-pound rule

Placards are required for Table 1 materials when the aggregate gross weight of all such materials in the load is 1,001 pounds or more.

DANGEROUS placard use

A DANGEROUS placard may replace individual placards for two or more Table 2 hazard classes in a load when the regulations allow it.

Label versus placard

Labels are applied by the shipper to packages and indicate the hazard class; placards are displayed on the vehicle and indicate the hazard of the load.

Cyanide and acid segregation

Cyanides and acids must never be loaded together or stored adjacent; contact can generate lethal hydrogen cyanide gas.

Cargo securement requirement

Cargo must be secured so it cannot shift, slide, or fall during transport; securement devices must be rated for the load and inspected before each trip.

Loading inspection

Before loading, check that packages are not leaking, damaged, or improperly labeled; reject or report any package showing evidence of leakage.

Food segregation

Hazardous materials must be loaded away from food, feed, and animal products to prevent contamination, and never in the same compartment as food.

Bulk package definition

A package with capacity greater than 119 gallons for liquids, greater than 882 pounds for solids, or greater than 1,000 pounds water capacity for gases.

Cargo tank outage

The empty space left in a tank to allow for expansion of the lading; the driver must know the required outage for the material being transported.

Portable tank test date

Portable tanks must be inspected and tested at intervals specified by the regulations; a tank with an expired test date may not be filled or transported.

Cargo tank markings

Cargo tanks must display the proper shipping name and UN/NA identification number on both sides and the rear, plus the correct placard.

National Response Center

The federal point of contact at 1-800-424-8802 for reporting releases of hazardous substances in reportable quantities; local responders are reached by calling 911.

Emergency Response Guidebook use

Identify the material by its UN/NA number, then use the guide number to find isolation distance, protective actions, and firefighting guidance.

Isolation distance guidance

Initial guidance from the ERG; for large spills or fire, use the larger distance and evacuate away from the direction the wind is blowing toward.

Leaking package response

Do not move a leaking package unless necessary to prevent further damage; contain the spill with absorbent material if trained and prevent entry into drains or waterways.

Explosive divisions

Explosives are divided into divisions 1.1 through 1.6 based on mass explosion hazard, projection hazard, fire hazard, and sensitivity; division 1.1 has the greatest mass explosion hazard.

Radioactive package labels

Radioactive packages carry White-I, Yellow-II, or Yellow-III labels; the driver must not open radioactive packages and must respect transport index limits.

Poison inhalation hazard

Division 6.1 materials marked POISON INHALATION HAZARD require special handling and must be kept away from food and ventilation intakes.

Corrosive material handling

Class 8 materials can destroy skin and metal; load them so leakage does not contact other cargo, and wear protective equipment when handling.

Security awareness

Recognizing and reporting suspicious activity, unauthorized access, or unusual inquiries about hazardous materials shipments to the carrier and, if warranted, law enforcement.

Load confidentiality

Do not discuss the nature of the load, routes, or schedules with strangers; keep shipping papers and placards secure and out of public view when parked.

Parking a loaded vehicle

Park in secure, well-lit areas, lock the vehicle, and avoid leaving a loaded vehicle unattended; if unattended, use a secure lot or terminal.

Safe driving with HazMat

Maintain a safe following distance, reduce speed in curves and on ramps, and brake smoothly to prevent load shift; hazardous loads have longer stopping distances.
