BLAST IN BENGALURU FORENSIC SCIENCE LABORATORY
Context: An explosion took place at the Forensic Science Laboratory in Bengaluru on Friday afternoon and left six people injured.
The explosion occurred at the Chemistry Lab in the FLS building when the personnel were testing a sample of an explosive substance suspected to be Tri Acetone Tri Peroxide (TATP).
- Acetone peroxide(also called APEX) is an organic peroxide and a primary high explosive.
- It is produced by the reaction ofacetone and hydrogen peroxide to yield a mixture of linear monomer and cyclic dimer, trimer, and tetramer
- The trimer is known astriacetone triperoxide (TATP) or tri-cyclic acetone peroxide (TCAP).
- The dimer is known asdiacetone diperoxide (DADP).
- Acetone peroxide takes the form of a white crystalline powder with a distinctivebleach-like odor (when impure) or a fruit-like smell when pure, and can explode powerfully if subjected to heat, friction, static electricity, concentrated sulfuric acid, strong UV radiation or shock.
- Until about 2015 explosives detectors were not set to detect non-nitrogenousexplosives as most explosives used were nitrogen-based.
- Nitrogen-free TATP has been used as the explosive of choice in severalterrorist bomb attacks since 2001.
