Hazardous Materials Overview

Flammable liquids require both "POISON" and hazard class placards when described as such.
Explosives should be loaded with checks for cargo space hazards, including loose floorboards and heat sources.
The transport index of radioactive materials indicates the level of control needed during transportation.

Transporting Compressed Gases

Compressed gas cylinders must be loaded upright, in racks, or in secure boxes to prevent turning.

Radiation and Hotloads

Total transport index for all radioactive material in a single vehicle is limited to a maximum of 50.
Animal or human food must not be transported with poisons.

Safe Parking and Vehicle Regulations

Vehicles carrying hazardous materials cannot park within 300 feet of open flames or crowds.
Drivers must have special training for controlling radioactive materials, updated every two years.

Vehicle Placarding

Hazardous materials vehicles need placards on all four sides.
The appropriate hazardous shipping lists help identify regulated products.

Shipper Responsibilities
