California CDL HazMat Endorsement Test · Build recall with a focused review session.

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

Hazard class 3
Flammable and combustible liquids. Placarded FLAMMABLE or COMBUSTIBLE, with a flash point at or below 60 degrees Celsius for flammable liquids under DOT rules.
HazMat employee training
General awareness, function-specific, safety, and security awareness training, plus DOT drug and alcohol testing, with recurrent training required within three years.
Four communication rules
Shipping papers, package markings, labels, and placards. Together they tell emergency responders and the public what hazard is present and how to respond.
Reportable quantity
The release amount of a hazardous substance that triggers notification under CERCLA. It appears in the hazardous substance list, not the HazMat table.
Basic description order
Proper shipping name, hazard class or division, UN/NA identification number, and packing group. The UN/NA number may precede the name or follow the class.
RQ on shipping paper
The letters RQ precede the proper shipping name when the material is a hazardous substance at or above its reportable quantity.
Emergency response phone
A number monitored at all times while the material is in transportation. It must appear on the shipping paper with the emergency response information.
Shipping paper retention
Carriers keep hazardous materials shipping papers for two years and hazardous waste papers for three years after the material is accepted.
Placard size
Placards are 10.75-inch squares placed on bulk packages and vehicles; labels are 4-inch squares placed on non-bulk packages.
DANGER placard use
May replace multiple placards only when 1,001 pounds or more of two or more hazard categories are loaded and 1,001 pounds aggregate of one category is present.
1,001 pound rule
Placarding is required when the aggregate gross weight of a single hazard class reaches 1,001 pounds; less may not require placards for table 2 materials.
Empty package marking
An empty package that held HazMat must be marked EMPTY and keep its labels and placards if residue remains inside.
Cyanide and acid
These must be segregated. Loading them together can generate deadly hydrogen cyanide gas, so they are never stored in the same space.
Load securement
Every package must be restrained with dunnage, load locks, straps, or tie-downs so it cannot shift, because a shifting load can rupture a container.
Oxidizer segregation
Oxidizers must be kept away from flammable liquids, combustible materials, and organic peroxides because they can intensify fire and accelerate burning.
Food and HazMat
Do not load HazMat in the same space as food, feed, or animals unless the material is packaged and segregated to prevent contamination.
Railroad crossing stop
Stop 15 to 50 feet before the crossing, look both ways, listen, and proceed only when the track is clear. Never stop on the tracks.
HazMat parking distance
Never park within 5 feet of a roadway edge, and keep at least 50 feet from an open flame or other source of ignition.
Explosives parking rule
For Division 1.1 through 1.6 explosives, park at least 300 feet from a bridge, tunnel, or occupied building unless the shipper directs otherwise.
Written route plan
Carriers must provide written routes for explosives and high-hazard radioactive materials; drivers must follow them and get authorization for deviations.
National Response Center
The federal point of contact at 1-800-424-8802 for reporting a hazardous materials release, in addition to calling 911 for local response.
ERG guide number
Found from the UN/NA number, it gives initial isolation distances, protective actions, and fire-fighting guidance for the material involved.
Reportable incident
A release that poses a continuing danger, causes death or injury, or requires evacuation. It must be reported and followed by a written DOT report.
Spill response position
Keep people upwind and uphill, isolate the area, deny entry, and do not attempt cleanup unless trained and equipped with proper protective gear.
Cargo tank endorsement
The N endorsement on a CDL is required to drive a tank vehicle. Drivers must know the tank design, capacity, fittings, and filling limits.
Bulk package threshold
A bulk package exceeds 119 gallons for liquids or 882 pounds for solids; bulk packages require placards and shipping papers.
Bonding and grounding
Connect the tank to the loading source to equalize static charge when loading flammables. No smoking, phones, or sparks nearby.
Maximum filling density
The limit on how full a tank may be, allowing space for liquid expansion. Overfilling can cause the tank to rupture.
Security awareness
Recognizing suspicious behavior, unattended packages, and unauthorized persons near HazMat, then reporting them to the carrier and authorities.
Vehicle lock and keys
Keep the vehicle locked and keys controlled. Never leave a placarded load unattended in an unsecured area where tampering is possible.
PPE selection
Gloves, eye protection, and respiratory protection chosen from the shipping paper and the ERG protective clothing table for the material involved.
Seal verification
Check seals and locks at each stop and compare them with the paperwork. A broken seal may mean tampering and must be reported before moving.
