Never transport damaged packages of explosives.
Do not take a package that shows any dampness
or an oily stain.
Do not transport Division 1.1 or 1.2 explosives in
a triples combination or in vehicle combinations if:
• There is a marked or placarded cargo tank in
the combination.
• The other vehicle in the combination contains
the following:
— initiating explosive
— radioactive materials labeled YELLOW III
— Division 2.3 or 6.1 poisons
— hazardous materials in a portable tank,
Spec 106A or 110A tank
Corrosive materials. If loading by hand, load
breakable containers of corrosive liquid one by
one. Keep them right side up. Do not drop or
roll the containers. Load them onto an even floor
surface. Stack carboys only if the lower tiers can
safely bear the weight of the upper tiers.
Do not load nitric acid above any other product.
Cyanides or cyanide mixtures may not be loaded
or stored with acids.
Load storage batteries so their liquid will not spill.
Keep them right side up. Make sure other cargo
will not fall against or short circuit them.
Never load corrosive liquids on the same transport
vehicle with:
• Division 1.1, 1.2, 1.3, or 1.5 explosives. (Refer
to Division 14 of the California Vehicle Code
for additional requirements.)
• Division 2.3, Zone A or 6.1, PG-I, Zone A,
poisons.
• Division 4.2 materials.
Never load corrosive liquids near or above:
• Division 1.4 explosives
• Division 2.3, Zone B, gases
• Division 4.1 or 4.3 materials
• Division 5.1 or 5.2 materials
- 120 -
Compressed gases, including cryogenic liquids.
If your vehicle does not have racks to hold cylinders,
the cargo space floor must be flat. The cylinders
must be loaded securely to prevent overturning.
They can be:
• Held upright or braced laying down flat.
• In racks attached to the vehicle.
• In boxes that will keep them from turning over.
Poisons. Never transport Division 2.3 (Poisonous
gas) or irritating materials in containers with
interconnections. Never load a package labeled
POISON or POISONOUS GAS in the driver’s
cab or sleeper.
Never load a package labeled POISON, POISON
- INHALATION HAZARD, or POISONOUS
GAS in the same vehicle with foodstuffs, feed, or
any edible material intended for consumption by
humans or animals, except as provided under 49
CFR 177.841(e). Packages with hazard labels or
package markings displaying the text “PG III” may
be loaded on the same vehicle with foodstuffs, feed,
or other edible material if separated as specified
in CFR 177.848(e)(3).
Radioactive materials. Some packages of
radioactive materials bear a number called the
“transport index.” The shipper labels these packages
Radioactive II or Radioactive III and prints the
package’s transport index on the label. Radiation
surrounds each package, passing through all nearby
packages. The transport index tells the degree of
control needed during transportation. The total
transport index of all packages in a single vehicle
must not exceed 50.
If the cargo you are transporting requires placarding,
you must have a HazMat endorsement.
Mixed loads. The rules require some products to be
loaded separately. They cannot be put together in
the same cargo space. Figures 9-5 and 9-6 list some
examples of the incompatibilities. The regulations
(The Segregation and Separation Chart) name other
materials to keep apart.
