Storage & Transportation::

Storage & Transportation: Of explosives. Presented by: Bushra Nawaz Mining engineering By: Bushra Nawaz

Storage: :

Storage: Proper storage prevents unauthorized access to the explosive material and reduces their deterioration. All explosive materials including blasting agents, detonators, detonating cord, and boosters, blasting caps, electrical and non electrical detonators should be stored in magazine. The magazines should be properly designed and located to comply with all applicable federal state and local laws, rules and regulations. By: Bushra Nawaz

Regulations Governing the Storage of Explosive Materials: :

Regulations Governing the Storage of Explosive Materials: The storage of explosive materials is regulated by: N.C . Department of Labor , U.S. Department of Justice, U.S. Department of Labor and U.S. Department of the Treasury. By: Bushra Nawaz

Classes of Explosive Materials:

Classes of Explosive Materials Explosive materials may be divided into three classes : • High explosives • Low explosives • Blasting agents Familiarity with the classes of explosive materials is essential to an understanding of the type of magazine in which they may be stored. By: Bushra Nawaz

High Explosives:

High Explosives • High explosives are explosive materials that, when unconfined, can be caused to detonate by means of a blasting Example: is dynamite. By: Bushra Nawaz

Low explosives:

Low explosives • Low explosives are explosive materials that, when confined, can be caused to deflagrate. Example Black powder, safety fuses igniters, igniter cords and fuse lighters are examples. By: Bushra Nawaz

Blasting agents :

Blasting agents These are substances that have a mass explosion hazard but are so insensitive that there is very little proba-bility of initiation or of transition from burning to detonation under normal conditions of transport. Example Ammonium nitrate , fuel oil and particular water gels are examples. By: Bushra Nawaz

Types of Magazines:

Types of Magazines There are five types of magazines for the storage of explosive materials: Type 1 magazines: Type 1 magazines are permanent magazines for the storage of high explosives. Other classes of explosive materials may also be stored in Type 1 magazines . It is a permanent structure such as a building, igloo, tunnel By: Bushra Nawaz

Type 2 magazines:

Type 2 magazines Type 2 magazines are mobile or portable indoor and outdoor magazines for the storage of high explosives such as a skid magazine, tractor or semi-trailer. Type 3 magazines Type 3 magazines are portable outdoor magazines for the temporary storage of high explosives while attended (a day box, for example). By: Bushra Nawaz

Storage Within Magazines, Types 1, 2, 3 and 4:

Storage Within Magazines, Types 1, 2, 3 and 4 When explosive materials are stored within Type 1, 2, 3 and 4 magazines, the following rules should be observed: Explosive materials must not be placed directly against interior walls and must be placed so as not to interfere with ventilation. Containers of explosive materials must be stored so that marks are visible. Except with respect to fibreboard or other non-metal containers, containers of explosive materials must not be unpacked or repacked inside a magazine or within 50 feet of a magazine. By: Bushra Nawaz

Storage Within Magazines, Types 1, 2, 3 and 4:

Storage Within Magazines, Types 1, 2, 3 and 4 Tools used to open or close containers of explosive materials must be of a nonsparking material, except that metal slitters may be used for opening fiberboard containers. A wood wedge and a fiber , rubber or wooden mallet must be used for opening or closing wood containers of explosive materials. Metal tools other than nonsparking transfer conveyors must not be stored in any magazine containing high explosives. By: Bushra Nawaz

Precautions:

Precautions Magazines can't be used for storage of metal tools or any commodity other than: Explosives, Blasting agents, Blasting supplies. Black powder must be stored separately from other explosives in a magazine. Explosives that aren't already age/or date marked by the manufacturer, must be marked with the manufacturing date before being stored in the magazine. By: Bushra Nawaz

PowerPoint Presentation:

Explosive material can't be stored where they could interfere with ventilation. Placed less than 2 inches from the interior walls. Magazine floors must be regularly swept and the sweepings properly disposed clean and dry,free of grit, paper, and used packages or rubbish. Identical grades and brands of explosives must be stored together, with the brands and grade marks showing. Smoking, matches, open flames, and spark producing devices aren't permitted,in any magazine,within 50 feet of an outdoor magazine. By: Bushra Nawaz

Storage limits:

Storage limits More than 300,000 pounds of explosive materials or 20,000,000 of detonators can't be stored in the same storage magazine. By: Bushra Nawaz

Transportation::

Transportation: Of explosive. By: Bushra Nawaz

Transportation:

Transportation Transpotation means the moving of explosives from one place to another. OR Moving explosives within a site (such as a factory, mine, quarry, construction site or a re-enactment display area) is exempt from the Regulations. By: Bushra Nawaz

Regulations:

Regulations Transportation of explosives on public highways are Regulated by: United States Department of Transportation The Washington utilities and transportation commission Administered and enforced by the Washington state patrol. By: Bushra Nawaz

Vehicle strength and condition:

Vehicle strength and condition All vehicles used for transporting explosives must: Be strong enough to carry the load without difficulty Be in good mechanical condition Have a tight floor in the cargo compartment(s) Not have any exposed spark producing metal inside the vehicle, which could come in contact with explosives. By: Bushra Nawaz

Open top vehicles:

Open top vehicles 1_Locations of use: While loaded with explosives, open top vehicles must only be used on: The job site or Roads that are closed to public travel 2_Containers . Explosives being transported in open top vehicles or trailers must be transported in: The original U.S. DOT approved shipping container or box, or A day box or portable magazine. By: Bushra Nawaz

PowerPoint Presentation:

3_Securing containers Explosive containers, boxes, day boxes, or portable magazines must be fastened to the bed of the vehicle or trailer. 4_Loading . Packages of explosives can't be loaded above the sides on open top vehicles. By: Bushra Nawaz

PowerPoint Presentation:

5_Tarpaulins (tarps). If an explosives transportation vehicle or trailer doesn't have a fully enclosed cargo area with nonsparking interior, the cargo bed and all explosive cargo must be covered with a flame and moisture proof tarp or other effective protection against moisture and sparks Whenever tarps are used for covering explosives, both the tarp and the explosives container must be fastened to the body of the truck bed with rope, wire. By: Bushra Nawaz

Vehicle Fire Protection:

Vehicle Fire Protection Driver training. The driver must be trained to use the fire extinguishers on the vehicle Equipment specifications. Vehicles used for transporting explosive materials must be equipped with fire extinguishers according to the gross vehicle weight.
