Ex: TNT, dynamite, nitroglycerine. 1.2 Explosives with a severe projection hazard. 1.3 Explosives with a fire, blast or projection hazard but not a mass explosion hazard. 1.4 Minor fire or projection hazard (includes ammunition and most consumer fireworks). 1.5 An insensitive substance with a mass explosion hazard (explosion similar to 1.1)
Dynamite is moderately sensitive to shock. Shock resistance tests are usually carried out with a drop-hammer: about 100 mg of explosive is placed on an anvil, upon which a weight of between 0.5 and 10 kg (1 and 22 lb) is dropped from different heights until detonation is achieved. [ 9 ]
In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
Stocks are surging higher with the S&P 500 nearing 5,000 for the first time.. To explain the rise, we recently asked some top Wall Street strategists to contribute to the latest edition of the ...
As investors shift focus toward cyclical stocks poised to benefit from economic recovery, investing in stocks like L Brands (LB), Mesa Air Group (MESA) & EOG Resources (EOG) seems prudent.
Detonation cord will initiate most commercial high explosives (dynamite, gelignite, sensitised gels, etc.) but will not initiate less sensitive blasting agents like ANFO on its own. 25 to 50 grain/foot (5.3 to 10.6 g/m) detonation cord has approximately the same initiating power as a #8 blasting cap in every 2 to 4 inches (5 to 10 cm) along its ...
Shock sensitivity is a comparative measure of the sensitivity to sudden compression (by impact or blast) of an explosive chemical compound. Determination of the shock sensitivity of a material intended for practical use is one important aspect of safety testing of explosives .
Dynamite is considered a "high explosive", which means it detonates rather than deflagrates. The chief uses of dynamite used to be in construction, mining and demolition. However, newer explosives and techniques have replaced dynamite in many applications. Dynamite is still used, mainly as bottom charge or in underwater blasting.
