RI 2280 Storing Carbide With Explosives

On March 14, 1921, an explosion occurred at about 6:15 A.~. on the premises of an iron-mining concern throug:1 which two magazines, one containing upwards of 9,000 pounds ot a high explosive of the dynamite class, and a second, 60 feet distant, containing upwards of 10,000 No. 6 detonators, were completely destroyed, and a ncratertt,? f3et deep by 30 feet in diameter, was excavated in the gro~ at ~he place whare the mag~iine containing the high explosive had been lo~ated. As a rule any eye wit~esses to the circumstances im.~ediataly preceding and d(irectly concurrent with a.c.ci.:lental ex;losions ar.e victims of s11ch explosions, and, therefore, the conclusions reached as to the cauoa. of such explosions must, perf'orce, be based aln:ost completely on circumstantial evidetJ.ce. In this iii.stance, b:ecause both the explosive and detonators were of -orov{:;d: character; because of the time of the day and the state of operations iit the·· time of the e:.q,losion; because the rerroteness of the location of the n:-1agazi::1es 1 0::1 the side of a ravine, easily admittfi of unobserved approach; beca:iise differencas existed, and because no obvious cause was at once apparent, there arose suspicfon that the explosion was not accidental.
