DOT Federal Mandatory Training Requirements for Packaging related tasks in accordance with 49 CFR
172.704 must be complied with as follows.

The DOT regulates hazardous materials (explosives) for safe transportation over public roads. To ensure
these hazardous materials in their original packages can be safely transported, the DOT requires that
anyone that performs a “function-specific” task associated with erecting a package, packaging product into
a container, closing and sealing a container of hazardous materials, and offing a package of hazardous
materials for shipment be Trained, Tested, and Certified that each one of these people know exactly what is
to be done correctly.

This Function-Specific training must be done within 90 days of employment and every three years after.
Records must be kept inclusive of the preceding three years, for as long as that employee is employed as a
hazmat employee and for 90 days thereafter.

Re-Closure of Specification Boxes
 for Packaged Explosives and Detonators
 TROJAN® Boosters
Explosive products are packaged in UN specification packages (boxes) meeting U.S. Department of
Transportation (DOT) shipping requirements. Whenever a UN specification box is opened, and one or
more units of explosives are removed for any purpose, a void is created, compromising the performance
of the specification box as originally tested.

TROJAN Booster packages opened in the field are required to be closed and sealed for transport over a
public road just as they were closed and sealed from the factory. For telescoping boxes, open the box by
cutting the tape holding the lid to the box bottom only. For boxes with flaps, open the box top only.

Consumers who purchase Dyno Nobel products, use less than full-box quantities, then transport partial
 UN specification boxes of explosives and/or detonators assume the responsibility to meet this DOT re-
 closure requirement, per49 CFR Part178.2 (c).

Federal Mandatory Training Requirements for Packaging:

Re-Closure of Specification Boxes for Packaged Explosives and Detonators
TROJAN® Boosters

To Close Telescoping Boxes: Place the box top onto and over the box bottom. These boxes have tape
sealing the box from the factory. The tape required to seal the box top to the bottom is 3-inch-wide 3M 371
or 3M 355. It should be applied over the original factory tape on the box bottom and extending a minimum of
2 inches up the sides of the box.

To Close Boxes with Flaps: Boxes with flaps require the minor (inner) flaps to be closed first and the
major (outer) flaps to be closed last. These boxes have tape sealing the box from the factory. The tape
required to seal the box is 3-inch-wide 3M 371 or 3M 355. It should be applied over the original factory tape
centered on the major flaps and extending a minimum of 2 inches down the sides of the box.
If units have been removed from the box, it is required that dunnage be used to fill the void created in the
box from the units removed to prevent freedom of movement of the remaining units in the box before the
box is closed and sealed. Appropriate dunnage would be paper, corrugated fiberboard, or anti-static bubble
wrap.

Any inner packaging inside the box (plastic bag) from the factory must remain in the box to maintain the
hazard class and/or packaging requirements of the material.
