1. Shippers package in order to ____ hazardous materials.

Contain

Release

Insulate

Shippers package hazardous materials in a way that is meant to completely contain the materials. Vehicles should be placarded to communicate the risk of the cargo.

2. How do you label a package if the hazardous materials label will not fit onto the package?

Place the label on a tag securely attached to the item.

Attach a QR Code to be scanned.

Reduce the size of the HazMat label to fit it completely on the item.

Shippers should place applicable diamond-shaped hazard warning labels on hazardous materials packages. If a label will not fit entirely onto a package, shippers may instead place the label on a tag that is securely attached to the package.

3. In the event of a fire, what should you do before opening trailer doors?

Check to see if the doors are hot.

Throw water on the doors.

Find someone else to open the doors.

If you are experiencing a truck fire, you should not attempt to open trailer doors without first feeling the doors to see if they are hot. If the doors are hot, there may be a cargo fire. In this case, leave the doors closed because opening the doors could worsen the fire by supplying it with more oxygen.

4. A clue that your shipment contains hazardous materials is that:

The shipper is in the business of firework or munition dealing.

The last shipment you picked up was labeled as hazardous.

The packaging looks damaged.

One clue that a shipment may contain hazardous materials is that the shipper is in a line of business that involves such materials. Examples include paint dealers; chemical suppliers; scientific supply houses; pest control businesses; agricultural supply firms; and dealers in explosives, munitions, or fireworks.

5. If a driver is given a leaking package or shipment, they should:

Accept it.

Refuse it.

Leave it on the side of the road.

It is a driver's responsibility to refuse packages or shipments of hazardous materials if they contain leaks.

6. Load hazardous materials:

Near heat sources.

Away from heat sources.

Away from shadows.

Always load hazardous materials away from heat sources. Be aware of regulations on explosive or flammable materials that prohibit them from being loaded in cargo spaces with heaters.
