In pressure situations involving inflammable gases it is doubtful whether permission from the relevant safety clearing authorities was taken by the "under construction" company. The company was reportedly "refurbished" after a gap. Were the safety rules flouted? Inexperienced workers, and inefficient higher supervision, could have contributed to the unfortunate incident. But procedures in producing gases are rarely adhered to, and law implementation has been very poor, in most chemical plants. During fire tragedies, workers get trapped inside unable to communicate with people outside.
