The Punjab State has witnessed quite a large number of explosions caused by
terrorists for more than one and half decades. Consequently, any incident
of an explosion in the state gives the impression of having resulted from t
errorist activity. The authors examined the scene of occurrences and carrie
d out laboratory examinations. The quantitative estimation of the aerosol m

available is within the critical limits of explosive forming mixture, has
substantiated the explosion due to the leakage of LPG. (C) 1999 Elsevier Sc
