What is an Earth covered magazine?
Earth Covered Magazine (ECM) structures are built to store AE. They are not designed to resist the damaging effects from an internal explosion, although they can effectively contain the effects from an explosion of very small AE quantities.
What is the net explosive weight new maximum capacity of an Earth covered magazine?
500,000 pounds
It is a magazine approved for the storage of 500,000 pounds net explosive weight (NEW) at the separation distances listed in AR 385-64.
What is the explosive range of dynamite?
Detonation pressures of explosives range from 10 to over 140 Kilobars (l Kilobar = 14,504 psi).
What is a above ground magazine?
AE storage magazines are classified as either Earth Covered Magazines (ECM) or Aboveground Magazines (AGM). This designation is based on the structural strength and ability of the magazine to withstand blast loadings resulting from an accidental explosion of an adjacent magazine as a Potential Explosion Site (PES).
What is the main risk of old ECMs?
What is the main risk of old ECMs? a. Older ECMs are only covered with earth on the top, adding to the weight which can possibly cause structural collapse 1.
What is the purpose of an inner pack?
Inner Packaging Solutions to protect your products Inner packaging help protect the product from transport and storage damages. The inner packaging surrounds the product and can be designed to protect against many different circumstances.
What is Ddesb stand for?

Can dynamite be traced?
They can be detected in very small amounts and very selectively in the complex composi- tion of extracts from the debris. An individual identification feature for any dynamite can be found in the relative amounts of the nitro- aromatics to each other.
What are the standards for earth covered magazines?
These standards govern the design, construction, and use of all AE storage magazines within the Department of Defense. Earth Covered Magazine (ECM) structures are built to store AE.
How much ammunition can be stored in an undefined ECM?
An Undefined ECM provides the lowest level of blast resistance and requires the greatest siting separation distances. An Undefined ECM may store up to 500,000 pounds NEW of hazard division 1.1, however many of the designs are based upon a lower storage capacity.
How to calculate the distance through the Earth?
1 Calculate Earth radius at each point 2 Calculate geocentric latitude at each point 3 Convert spherical coordinates of each point to cartesian coordinates, that is, from calculated radius, geocentric latitude and longitude to x,y,z. 4 Calculate distance using Euclidean distance formula
How much earth cover do you need for an ECM?
Earth cover over the top, sides, and rear of the ECM. A minimum of 2 feet (24 inches) of earth cover is required over the ECM. Reinforced concrete wingwalls on either side of the headwall.
