PROPERLY SECURED CARGO
Secure all cargo to prevent damage. Secure hazardous cargo not only
to prevent damage to the cargo, but also to prevent damage to
equipment and injury to personnel.
Secure by bracing, blocking,
tying down, and covering.
FM 55-30, Army Motor Transport Units and
Operations, describes techniques used to secure cargo on motor
vehicles.
TM 55-2200-001-12, Application of Blocking, Bracing, and
Tiedown Materials for Rail Transport, describes techniques used to
secure cargo on railcars. CFR 49 includes securing requirements for
hazardous cargo such as detonators, flammable cryogenic liquids, and
flammable gases.
Consult each of these sources to determine the
proper measures for securing a particular hazardous cargo.
The following are
general
criteria
for
determining
if
cargo
is
properly secured.
Block, brace, or lash cargo so that no movement can occur
during transport.
Load boxes and crates so that the stronger sides are parallel
with the direction of vehicle movement.
Load drums, kegs, carboys, and cylinders
so
that
their
openings (bungs, valves, necks) are face up.
Adequately protect materials that are
sensitive to shock,
puncturing, denting, or crushing by
using crates, crib
blocking, or other appropriate methods.
Secure materials that may emit poisonous or flammable gases
while allowing ventilation for the gases.
Protect materials against moisture with closed
containers,
closed vehicles, or tarpaulins as appropriate.
Protect flammable, combustible, and explosive materials from
all sources of heat, flame, and sparks.
Never load cargo higher than the top edge of the sides of the
transporting vehicle.
Load cargo so that the weight is evenly distributed over the
load bed.
