Procedures for using emergency exits

1. Put the lifesaving channel installation frame into working condition, open the backpack and take out the channel tube, and fix the connecting belt hook on the workbench of the lifting vehicle.
2. Put down the rescue channel, and adjust the length of the channel cylinder with the zipper according to the actual height of use.
3. The rescued person wears a safety belt, hooks the two connecting hooks into the two metal rings on the safety belt, and grasps the handrail on the square frame with both hands.
4. After the rescued person enters the passage, he will descend in the passage, and the descending speed is controlled by the firefighters on the ground. The rescued person puts his hands upward without any manipulation action.
5. When approaching the ground, the firefighters on the ground should appropriately increase the control force and reduce the descending speed so that the rescued person can land on the ground smoothly.
