You are one of three scoop operators. During the first part of the shift an entry was shot and partly loaded. One of the other scoop operators, Speedy, has complained that he was dizzy and sick to his stomach. Otherwise, the shift has gone on as usual. You reenter the mine after lunch and notice that some smoke is still hanging. You are worried that the ventilation may not be adequate. Soon the two scoop operators, Speedy and Chester, who are at the face, go down. You must decide what to do to help them.
