PART C - INSPECT LOADED CARGO
You should always ensure that cargo is properly loaded to prevent
damage to cargo, damage to equipment, and injury to personnel. This
part will discuss the procedures and regulations to follow when
loading hazardous cargo.
CARGO COMPATIBILITY RULES OF CFR 49
Many types of hazardous materials are incompatible with one another.
Transporting incompatible hazardous materials together is prohibited
by CFR 49.
Section 174.81 of CFR 49 contains a Segregation and Separation Chart
of Hazardous Materials in railcars. The table shows which hazardous
materials (principally ammunition and explosives) must not be loaded
or stored together and is located in Appendix B of this subcourse.
The table is a matrix listing hazardous materials in horizontal row
and vertical column. The articles listed here must not be loaded or
stored together.
For example, detonating fuzes Class A, with or
without radioactive components (g in the column) must not be loaded
or stored with high explosives or propellent explosives Class A (b in
the row). If a dotted line appears at an intersection of a row and
column, the articles listed may be loaded or stored together.
Exceptions and limitations are indicated by footnotes.
Section 177.848 of CFR 49 contains the Segregation and Separation
Chart of Hazardous Materials for determining compatibility when
shipping by motor vehicle.
The table, which is reproduced in the
extract of CFR 49 (see Appendix B) is read in the same manner as the
table in Section 174.81.
In
general,
hazardous
materials
that
are
not
specified
as
incompatible in these tables may be shipped together.
Hazardous
materials may generally be transported with nonhazardous materials.
There is one major exception to this rule: A carrier may not
transport any package of material bearing a poison label with food
stuffs, feed, or any edible material intended for consumption by
humans or animals.
MOTOR VEHICLE TRANSPORT
The following measures are required in the loading and securing of
hazardous materials when transport is by motor vehicle.
General Handling Requirements
Secure and brace packages to prevent movement in the vehicle.
