What Is Dynamite? Why Decades-Old Stashes Turn into Lethal Hidden Bombs
By Maya Lin-Takahashi
Q1: Can old dynamite explode spontaneously without a spark or flame?
Yes. Severely deteriorated dynamite that has undergone extensive nitroglycerin exudation does not need an open flame or an electrical spark to detonate. Pure liquid or crystalline nitroglycerin can ignite from microscopic friction, mechanical shock, falling debris, sudden heat changes, or even the slight flex of a deteriorating cardboard carton.
Q2: Why do modern demolition crews avoid using dynamite today?
Contemporary controlled demolition contractors and commercial mining operations rely almost entirely on ammonium nitrate emulsions, ANFO (ammonium nitrate/fuel oil), and modern booster charges. These modern explosives are far cheaper to manufacture, do not give workers the severe vasodilation headaches caused by handling nitroglycerin vapors, and will not detonate without heavy, high-velocity boosters, eliminating accidental warehouse explosions.
Q3: What should you do if you discover what appears to be old dynamite on your property?
Do not touch, lift, or attempt to inspect the sticks. Do not attempt to transport them to a local police station or firehouse. Evacuate the immediate structure, keep other individuals away from the area, and call 911 immediately. Inform dispatch that you have discovered suspected commercial explosives so they can notify the regional bomb squad and certified ATF explosive specialists.
