Columbia Gas will pay rent to landlords for the period in which the rental property was without heat or hot water, regardless of whether the tenant has been withholding rent. The principle is, the shock wave ahead of combustion wave breaks or pulls down the water bags suspended on the roof, the water mist thus formed will diffuse and seal off the entire roadway section. Around the world, on average, four coal miners die for each million tons of coal recovered. 7.4.4 Monitors on explosion-protected vehicles energised by a battery or diesel engine 87 7.4.5 Monitors on other explosion-protected mobile plant 87 7.4.6 Monitors on a hydro mining panel 88 7.4.7 Use of portable gas monitors 89 7.4.8 Monitoring where methane drainage is in place 89 7.5 Alarms 89 Rescuers and relatives of the miners stood about the mine shaft helpless.
