explanation and go directly to the answer
Preparing and shipping mixed loads of HAZMAT cargo
is a
complicated issue, yet it is one we are often faced with.
This page will address that issue only in terms of HAZMAT shipped by
OOT. OOT ships explosives in 5 classes: 1.1D, 1.4B,
1.4C, 1.4D, and 1.4S; and other HAZMAT in either Division 4.1
(Flammable Solids) or Division 5.1 (Oxidizers).
For explosives, mixing of loads is generally
determined by the compatibility group letter in the
classification, i.e., the "D" in 1.1D or 1.4D, the
"S" in 1.4S, and so on. The general rule is,
regardless of class/division (the numeric part of the
classification), if the compatibility group letter matches, then
the goods can be shipped together. This means that 1.1D and
1.4D can be shipped together.
There are also certain combinations of
compatibility group letters that can be shipped together.
For example, any combination of compatibility groups C, D, or E is
allowed; however, the combined load must be assigned to
compatibility group E.
Getting complicated? Well it gets even
more so. There are special rules for shipment of detonators
in mixed loads and there is the issue of mixing explosives with
other hazard classes. To sort all this out, the U.S.
Department of Transportation publishes guidelines in the Hazardous
Materials Regulations. There are separate guidelines for
each mode of transportation:
The Answer
Since most shipments of OOT HAZMAT product are
by highway, we've prepared the following chart, which we hope will
help make mixed loading determinations easier. The following
table is based upon the requirements of 49
CFR 177.848, except that it is limited to only those HAZMAT classes OOT offers/ships.

To use the table, locate
the intersection between the two classes in question and review
the answer there. A "Yes" means you can ship the
two together without restriction. A "No" means you
cannot. A number in parentheses after either a
"Yes" or a "No" answer means there are
additional requirements that apply or that an exception that
applies. In the table shown
above, there are only two conditional requirements:

A (1) means that any combination of explosives from compatibility groups C, D, or E is assigned to compatibility group E.

A (2) means that the Special
Detonator Rule applies. Click
here to review that rule.
Some examples

Can
I ship 1.1D cutters with 1.4S power charges?
At the 1.1D/1.4S intersection there appears a "Yes
(2)". The "(2)" means the Special
Detonator Rule applies and since the question is not about
detonators, the answer is, "Yes".

Can
I ship 1.4S charges with 4.1 propellant sticks?
At the 1.4S/4.1 intersection there appears a
"Yes". This means you can ship these two
products together.

Can
I ship 1.1D cutters and charges with 4.1 propellant sticks and
5.1 StimGun™ products? The
answer is, "No". 1.1D products cannot be
transported with 4.1 and/or 5.1 products.

Can
I ship 1.1D perforators with 1.4S bidirectional boosters?
Like in the 1.1D cutter/1.4S power charge example given above,
at the 1.1D/1.4S intersection, there is a "Yes (2).
OOT bidirectional boosters are classed as UN0384 Components,
explosive train, n.o.s. Since OOT bidirectional
boosters are not detonators, the Special
Detonator Rule does not apply and the answer is
"Yes", 1.1D perforators and 1.4S bidirectional
boosters may be transported together without restriction.

Can
I ship electric and/or nonelectric detonators with detonating
cord? Regardless of the class of detonator
(1.1, 1.2, or 1.4) and regardless of the compatibility group
(B, D, or S for detonators), the Special
Detonator Rule applies. If the detonating cord is
classed 1.1D, the answer is "No" unless you can meet
either #1 or #2 under the Special
Detonator Rule. If the detonating cord is classed
1.4D, the answer is yes, if you can meet #1, #2,
or #3
under the Special
Detonator Rule.

Can
I ship electric and/or nonelectric detonators with any 1.1
products? Again, the Special
Detonator Rule applies and, unless you can meet #1
or #2 under that rule,
the answer is "No".

Can
I ship electric and/or nonelectric detonators with any 1.4D
products? (added
5/27/2010) For 1.4D detonating cord, please
see Can I ship electric and/or
nonelectric detonators with detonating cord"
(above). For all other
1.4D products (including, but not limited to, 1.4D
perforators), regardless of the class of detonator
(1.1, 1.2, or 1.4) and regardless of the compatibility group
(B, D, or S for detonators), the answer is "Yes".
Recently, DOT has clarified this issue in a couple of
interpretations issued to Austin Powder Company in 2008 (click
here for copy) and to Titan Specialties in 2010 (click
here for copy).
Special
Detonator Rule
And finally, at long last, the Special
Detonator Rule.
What is a detonator? Owen products
that are detonators are the following:

Electric detonators (UN0030, UN0255,
UN0456)

Nonelectric detonators (UN0455)

Detonating fuzes (UN0106, UN0367, UN0410)
Basically, in 49
CFR 177.835(g), the DOT prohibits transport of detonators on
the same motor vehicle with Class 1.1, 1.2, 1.3, and 1.5
products. Additionally, detonators cannot be transported on
the same motor vehicle with 1.4D detonating cord. There are
some exceptions to this prohibition:
1. Detonators may be
shipped with 1.1, 1.2, 1.3. and 1.5 materials and/or 1.4D
detonating cord if the detonators are packed in an MC201
container (see 49 CFR 178.318).
2. Detonators may
be shipped with 1.1, 1.2, 1.3. and 1.5 materials and/or 1.4D
detonating cord if the detonators are packed in an IME 22
container (See IME SLP22. Contact the IME
for details). Under this rule, other packaging
options may be used, but they must be approved by DOT prior to
use.
3. Detonators may be
shipped with 1.4D detonating cord if they (the detonators and the
cord) are packaged in accordance with 49 CFR 173.62 and the
packages of detonators are separated from the packages of
detonating cord by at least 24 inches (61 cm).
4. Detonators may be shipped with
other detonators. Thus, 1.1B, 1.2B, 1.4B and/or 1.4S
detonators may be shipped together.
