You are the foreman on a 3 entry longwall development panel 2,500 feet from the mains, and 15,000 feet from the portal. Suddenly a cloud of smoke comes up the belt entry. As you warn and assemble the crew the smoke becomes thick. A call from the surface orders the immediate evacuation of the section. The location of the fire is unknown. You lead the miners out the intake air entry only to encounter heavy smoke after a few crosscuts. You direct the miners to don their SCSRs and continue on. One miner cannot keep up and delays the escape of the others. Soon the smoke becomes so thick that visibility is only a few inches. The portal is still over two miles away. You must help your crew escape from the mine before their SCSRs are depleted, but you also do not want to leave the one miner behind.
