Read the passage and answer the following questions:-

54 miners at the Bhatdih colliery of Nagada were trapped Wednesday night following a blast due to the accumulation of gasses. It was about 8 p.m. when the explosion, caused by the pressure due to the accumulation of methane and carbon monoxide, shook the colliery belonging to the Bharat Coking Coal Limited (BCCL). The intensity was so high that a one-tone trolley in inclination number 17 was thrown out. Four rescue teams have been constituted. But they don't have adequate number of Oxygen masks to enter the deep mine where the incident occurred. Most of the trapped miners are between the ages of 20 and 30. Family members and union leaders have blamed the BCCL management for the incident. This is one of the BCCL's poisonous mines. No safety measures have been adopted by the management. Water sprinkling facilities and gas testing machines should be available in the colliery. But no such arrangements have been made here, said a union member.
