A Few Major Projects.

To demonstrate how explosives have helped shape our world, we can look to some well known projects that would not have been possible without the use of explosives.
Three tunnels were constructed by the use of explosives and even today stand out as benchmarks in the history of explosives:

Mount Cenis, a 13-kilometer railway tunnel driven through the Alps between France and Italy (1857-71)

The 6.4 kilometer Hoosac Railway Project

The Sutromine Development Tunnel in Nevada (1864-74).

Alfred Nobel: Life and Career

Born in Stockholm, Alfred Nobel was the fourth son of Immanuel Nobel (1801–1872), an inventor and engineer, and Andriette Ahlsell Nobel (1805–1889). The couple married in 1827 and had eight children. The family was impoverished, and only Alfred and his three brothers survived past childhood. Through his father, Alfred Nobel was a descendant of the Swedish scientist Olaus Rudbeck (1630–1702),and in his turn the boy was interested in engineering, particularly explosives, learning the basic principles from his father at a young age.
Following various business failures, Nobel's father moved to Saint Petersburg in 1837 and grew successful there as a manufacturer of machine tools and explosives. He invented modern plywood and started work on the "torpedo".In 1842, the family joined him in the city. Now prosperous, his parents were able to send Nobel to private tutors and the boy excelled in his studies, particularly in chemistry and languages, achieving fluency in English, French, German, and Russian. For 18 months, during 1841–1842, Nobel went to the only school he ever attended as a child, the Jacobs Apologistic School in Stockholm.

As a young man, Nobel studied with chemist Nikolai Zinin; then, in 1850, went to Paris to further the work; and, at 18, he went to the United States for four years to study chemistry, collaborating for a short period under inventor John Ericsson, who designed the American Civil War ironclad USS Monitor. Nobel filed his first patent, for a gas meter, in 1857.[2][5][1]
The family factory produced armaments for the Crimean War (1853–1856); but, had difficulty switching back to regular domestic production when the fighting ended and they filed for bankruptcy. In 1859, Nobel's father left his factory in the care of the second son, Ludvig Nobel (1831–1888), who greatly improved the business. Nobel and his parents returned to Sweden from Russia and Nobel devoted himself to the study of explosives, and especially to the safe manufacture and use of nitroglycerine (discovered in 1847 by Ascanio Sobrero, one of his fellow students under Théophile-Jules Pelouze at the University of Turin). Nobel invented a detonator in 1863; and, in 1865, he designed the blasting cap.
On 3 September 1864, a shed, used for the preparation of nitroglycerin, exploded at the factory in Heleneborg Stockholm, killing five people, including Nobel's younger brother Emil. Dogged by more minor accidents but unfazed, Nobel went on to build further factories, focusing on improving the stability of the explosives he was developing. Nobel invented dynamite in 1867, a substance easier and safer to handle than the more unstable nitroglycerin. Dynamite was patented in the US and the UK and was used extensively in mining and the building of transport networks internationally. In 1875 Nobel invented gelignite, more stable and powerful than dynamite, and in 1887 patented ballistite, a forerunner of cordite.
Nobel was elected a member of the Royal Swedish Academy of Sciences in 1884, the same institution that would later select laureates for two of the Nobel prizes, and he received an honorary doctorate from Uppsala University in 1893.
Nobel's brothers Ludvig and Robert exploited oilfields along the Caspian Sea and became hugely rich in their own right. Nobel invested in these and amassed great wealth through the development of these new oil regions. During his life Nobel issued 350 patents internationally and by his death had established 90 armaments factories, despite his belief in pacifism.
In 1891, following the death of his mother and his brother Ludvig and the end of a long standing relationship, Nobel moved from Paris to San Remo, Italy. Suffering from angina, Nobel died at home, of a cerebral haemorrhage in 1896. Unbeknownst to his family, friends or colleagues, he had left most of his wealth in trust, in order to fund the awards that would become known as the Nobel Prizes. He is buried in Norra begravningsplatsen in Stockholm.

Alfred Nobel:Father of Explosives

Alfred Bernhard Nobel ([äl'fred bern'härd nōbel'] About this sound listen) (21 October 1833 – 10 December 1896) was a Swedish chemist, engineer, innovator, and armaments manufacturer. He was the inventor of dynamite. Nobel also owned Bofors, which he had redirected from its previous role as primarily an iron and steel producer to a major manufacturer of cannon and other armaments. Nobel held 350 different patents, dynamite being the most famous. He used his fortune to posthumously institute the Nobel Prizes. The synthetic element nobelium was named after him. His name also survives in modern-day companies such as Dynamite Nobel and Akzo Nobel, which are descendants of the companies Nobel himself established.

Department of Transportation (DOT) changes


a. In 1991 the DOT adopted into federal law a different system
for hazard classification of dangerous goods. The new system is
essentially that which is used by United Nations for the transportation
of dangerous goods. The total phase-in period for the new
system is ten years. The 49 CFR (App A, Ref 3) has more detailed
information regarding the different phase-in periods for specific
situations and should be consulted as the authoritative source. The
JHCS will continue to have the old DOT information for the entire
phase-in period of ten years.
b. For new items added to the JHCS after April 1991, there will
be no DOT (old system) information added.
c. For those items added after April 1991, the DOT hazard class
for Class 1 items will be the DoD Hazard Division Compatibility
Group. Any parenthetical values appearing in the DoD hazard class
will not be included in the DOT hazard class. For those items where
the DoD Hazard Division Compatibility Group is other than Class 1
 (i.e., Class 2–9), the DOT class will consist only of the DoD Hazard
Division. No Compatibility Group for Class 2–9 will be included in
the DOT hazard class; whereas, it will be for DoD.
d. For those items entered in the JHCS after April 1991, the DOT
label for Class 1 items will be the word “Explosive” followed by the
DOT hazard class (i.e., 1.2C). For Class 2–9 consult 49 CFR (App
A, Ref 3).
e. For those items entered after April 1991, the DOT container
marking for Class 1 items will consist of the Proper Shipping Name
(as defined by the UN Serial Number), the UN Serial Number, and
the NSN or part number. The NSN or part number may be used
only if it is directly traceable to a DOT assigned registration number
(i.e., “EX” number). All of these data elements are in the JHCS.

Joint hazard classification system-Background


a. The JHCS is a data base containing hazard classification and
safety data for explosive items, ammunition and ammunition related
items (i.e., items containing some Class 1 material) of the DODCs.
The information contained in the JHCS is necessary for safe storage
and transportation. The JHCS was established to promote consistency
among DoD hazard classification actions, to eliminate duplic
a t i o n a n d c o n f l i c t a m o n g c o m p o n e n t h a z a r d c l a s s i f i c a t i o n
assignments, and to provide a single source document of authoritative
and controlled hazard classification data for the entire DoD.
b. The JHCS contains the following data elements for DoD explosive
items, ammunition and ammunition-related items:
(1) DODC code — this code indicates which component is the
proponent of an item’s hazard classification.
(2) Tri-Service coordination code — this code indicates whether
or not Tri-Service coordination has been completed.
(3) Item nomenclature.
(4) Department of Defense identification code (DODIC), Locally
Assigned Ammunition Reporting Code (LARC), or Navy Ammunition
Logistic Code (NALC).
(5) National Stock Number (NSN).
(6) DOD hazard division transportation and storage Compatibility
Group (CG).
(7) United Nations (UN) Serial Number.
( 8 ) D e p a r t m e n t o f T r a n s p o r t a t i o n ( D O T ) h a z a r d c l a s s ( p r e -
1991).
(9) DOT marking (with supplementary expansion ) (pre–1991).
(10) DOT label (pre–1991).
(11) Hazard symbol.
( 1 2 ) H i g h e x p l o s i v e w e i g h t ( H E W ) ( i n u n i t s o f p o u n d s a n d
kilograms).
( 1 3 ) N e t p r o p e l l a n t w e i g h t ( N P W ) ( i n u n i t s o f p o u n d s a n d
kilograms).
(14) Net explosive weight (NEW) — the total of all Class 1
material used for transportation purposes (in units of pounds and
kilograms).
(15) Net explosive weight for Q–D (NEWQD) — that combination
of explosive weight and propellant weight used to determine the
explosive weight used for quantity-distance purposes (in units of
pounds and kilograms).
(16) Part number and/or drawing number.
c. The above data will be sorted in the following sequences for
output purposes:
(1) NSN.
(2) Federal Stock Class (FSC)/ DODIC/National Item Identification
Number (NIIN).
(3) Part number (drawing number)/NSN.
(4) Alphabetical listing by Item Nomenclature.

Moderate Fire Hazard, No Blast Materials


(CLASS 1, DIVISION 4). Items in this division present a fire hazard with no blast hazard and virtually no fragmentation or toxic hazard beyond the fire hazard clearance specified for high-risk materials. However, separate facilities for storage and handling of this division should not be less than 100 feet from other facilities. However, if the facilities are of fire-resistive construction, they may be 50 feet from each other. If devices containing explosives are such that accidental ignition during storage or transport will not cause external damage to the devices, either by fire, smoke, heat, loud noise, or by visible damage to the outer packaging, they are not considered Class 1 items. These devices may be considered inert for storage purposes and marked AMMUNITION NONEXPLOSIVE for transport purposes. Certain articles within the division that contain one ounce or less of explosives have (based on test results) been classified as Class 1, Division 4S. These articles may be considered inert for storage purposes, and they are not subject to explosive transportation regulations. Articles containing larger quantities of explosives, also classified as Class 1, Division 4S, may be considered inert for storage purposes. However, they must be reviewed on an individual basis to determine whether explosive transportation regulations are applicable.

Storage Compatibility Groups


GROUP J - Ammunition in this group contains both explosives and flammable liquids or gels. This ammunition contains flammable liquids or gels other than those that are spontaneously flammable when exposed to water or to the atmosphere. Examples of these items are liquid- or gel-filled incendiary ammunition, fuel air explosive (FAE) devices, flammable-fueled missiles and torpedoes. 
GROUPK- Ammunition in group K contains both explosives and toxic chemical agents. Ammunition in this group contains chemicals specifically designed for incapacitating effects that are more severe than lachrymation. Examples of these items are artillery or mortar ammunition (fused or un-fused), grenades, and rockets or bombs filled with a lethal or incapacitating chemical agent.
GROUP L - Ammunition in-group L is not included in other compatibility groups. Ammunition in this group has characteristics that don't permit storage with other types of ammunition, explosives, or dissimilar ammunition within this group. Examples of these items are water-activated devices, prepackaged hypergolic liquid-fueled rocket engines, certain fuel-air-explosive (FAE) devices, TPA (thickened TEA), and damaged or suspect ammunition of any other group. Types of ammunition having similar hazards can be stored together but cannot be mixed with other groups. 
GROUP S - Ammunition in this group presents no significant hazard. It is designed or packed so all the accidental functioning hazards are confined within the package, unless the package has been degraded by fire. In this case, all blast or projection effects are limited to the extent they will not significantly hinder fire-fighting operations. Examples of these items are thermal batteries, explosive switches or valves, and other ammunition items that are packaged to meet the criteria established for this group. Ammunition and explosives are assigned to compatibility groups. When stored within their assigned group, ammunition and explosives can be stored together without significantly increasing either the probability of an accident or, for a given quantity, the magnitude of the effects of such an accident. The mixing of storage compatibility groups is permitted by NAVSEASYSCOM, as shown below. The mixing of storage compatibility groups other than those shown below must be approved by NAVSEASYSCOM.
