Placarding
Table 1.
Any
quantity of any hazardous material listed in Table 1 requires placarding.
172.504(a)
Placarding
Table 2 lists the remainder of the hazardous material classes that require
placards. However, Table
2 material requires placarding only when the aggregate
gross weight of all Table
2 hazardous materials on the transport vehicle or in the
freight container is
1,001 pounds or more.
Transport
vehicles and freight containers transporting less than 1,001 pounds gross
weight of Table 2 material
MAY be placarded. Placards are not required.
172.504(c)(1)
Table 2,
49 CFR 172.504

Exceptions
and options are provided in sub-sections f and g of 172.504. In
placarding
Table 2, weight is only one of the factors to consider.
172.504(a)
If
a transport vehicle or freight container carries two or more hazard classes
from
Table
2 requiring different placards, the DANGEROUS placard may be used in
place of the hazard class
placards.
172.504(b)
THE
DANGEROUS PLACARD MAY BE
USED
FOR TWO OR MORE TABLE 2
MATERIALS
The
specific Table 2 placard must be used when 1,000 kilograms or more of one
class of hazardous material
is loaded at one loading facility. In this case, the
DANGEROUS
placard may not be used.
Table

More Of One Class
Loaded At One Location
Must Be Placarded For
That Hazard Class
No
Dangerous Placard
on Cargo Tanks
on Cargo Tanks
The
DANGEROUS placard may not be used on a cargo tank, portable tank or tank
car. Instead, the specific
placard for each hazardous material must be applied. In
addition, the DANGEROUS
placard may not be used for placarding Table 1
material.
172.504(a)-(b)
Does not apply to:
Cargo
Tanks 
Portable Tanks
Poison Inhallation Hazard Materials
Air and Water Shipments
No
placard is required for Table 2 material when the gross weight is less than
1,001
pounds.
However,
you must placard Table 2 material when shipped:
-
in portable tanks, cargo tanks or tank cars;
-
by air or water; or
-
in transport vehicles and freight containers carrying material identified
on a
shipping paper as a "Poison-Inhalation
Hazard."
172.504(c)

Cleaned and Purged or Loaded
with Non-Hazardous Materials
Each
cargo tank or portable tank required to be placarded when it contained a
The
placard MUST be removed if the tank is reloaded with a nonregulated material.
The
placard MUST be removed once the tank is cleaned and purged of all
172.514(b)
Each
placard on a motor vehicle or rail car must be readily visible from the direction
it faces. Placards must
be on each side and each end. If coupled to another motor
vehicle or rail car,
visibility is not required from the direction it faces. For example,
this tractor semi-trailer
has the placard affixed to the front of the trailer but the cab
blocks the placard from
view. This is permitted.
172.516(a)
49
CFR 172.516
The
required placard on the front of a motor vehicle may be on the front of a
truck
tractor instead of, or
in addition to, the placard on the attached cargo body.
172.516(b)
If
visibility requirements are met, freight containers or portable tanks may
be
placarded instead of
the motor vehicle. But, if a portable tank or freight container
requiring placarding
is inside a transport vehicle, the van type trailer must be
placarded. By D.O.T.
interpretation loads may be placarded instead of the vehicle
as long as the visibility
requirements are met.
Each
placard must be securely attached and maintained in good condition.
Placards
must be located clear of appurtenances and devices, away from dirt and
water from wheels and
at least three inches from any detracting markings.
Placard
words and/or numbers must be displayed horizontally.
172.516(c)
There
are some special placarding requirements that the shipper, carrier or
warehouse person must
follow. For example:
A
PIH material also needs the poison or poison gas placard.
When
a shipping paper describes a material as a "poison inhalation hazard"
the
poison placard is required.
The placard must be displayed on each side, on the
front, and on the back
of the transport vehicle, portable tank, or freight container.
This
placard is required in addition to any other required placards.
