A contact explosive is a chemical substance that explodes violently when it is exposed to a relatively small amount of energy (e.g. friction, pressure, sound, light). Though different contact explosives have varying amounts of energy sensitivity, they are all much more sensitive relative to other kinds of explosives.
Aftermath of the 2020 Beirut explosion.. The most dangerous chemical accident recorded in history was the 1984 Bhopal gas tragedy in India, in which more than 3,000 people died after highly toxic methyl isocyanate was released at a Union Carbide pesticides factory.

They have accompanied a sharp increase in global antisemitism and Islamophobia, as well as anti-Israeli sentiment and anti-Palestinian sentiment or broader anti-Arab sentiment. [1]
A high explosive violent reaction (HEVR) includes reactions ranging from a fast deflagration of the high explosive (HE), up to and including a detonation of the high explosive. The explosive wave may be subsonic or supersonic.
Photographs and videos showed extensive destruction in and around the warehouse compound, [34] [35] with an enormous crater at the blast site. [15] The buildings of seven more surrounding logistics companies were destroyed, [ 36 ] and large quantities of intermodal container stacks were toppled and thrown by the forces of the explosions.

In simple terms, the 'Barking Dog' reaction is a combustion process, in which a fuel (carbon disulfide, CS 2) reacts with an oxidizing agent (nitrous oxide, N 2 O), producing heat and elemental sulfur. The flame front in the reaction is a zone of very hot, luminous gas, produced by the reactants decomposing. 8 N 2 O + 4 CS 2 → S 8 + 4 CO 2 ...
