16. What safety considerations should be taken into account when dealing with red coke spill incidents? Answer: Since the coke pusher, the coke stopper, and the coke quencher are located on separate sides of the coke oven, communication between them is possible only through walkie-talkies and interlocking controls among these three vehicles. If the interlocking system is disabled, accidents can easily occur if there is no proper communication or confirmation in place; the coke pusher might push the red coke onto the tracks occupied by the coke stopper and the coke quencher, or even knock over the coke stopper itself. Such accidents are commonly referred to as red coking landing. When dealing with incidents involving red coke on the ground, it is necessary to prevent accidents such as burns from red coke, scalds, injuries caused by vehicles, injuries from steam, electric shocks from electrical circuits, and damage to equipment ； After a red coke spill occurs, the following points should be taken into account: ensure unified command during handling, maintain accurate communication, and prevent injuries caused by improper operations. Immediately inform the coke pusher to stop pushing the coke, move the coke stopper car to a safe location, remove the red coke from it, and then cut off the power supply to the electric track of the coke stopper car to prevent electric shock ； Use fire-fighting water to extinguish the red coke on the ground, then manually transport the coke to the cooling platform. When cleaning the coke, take proper precautions to avoid being burned by the hot coke and to prevent injuries from tools such as shovels ； During accident handling, the power outage and restoration procedures must be strictly followed. If the red coke has landed before the coke pushing operation is completed, it is necessary to promptly clear the red coke from the tracks; once the coke stopper car and the fire extinguishing car are in place, the remaining coke should be pushed away. 17. When dealing with secondary foci, what safety issues should be considered? Answer: A secondary coke jam, also known as a difficult coke pushing situation, occurs when the resistance encountered during coke pushing is too high, exceeding the capacity of the coke pushing motor, and as a result the coke pushing rod cannot move forward. When dealing with such situations, it is necessary to prevent accidents such as burns, scalds, injuries caused by vehicles, injuries from steam, electric shocks from electrical conductors, and carbon monoxide poisoning. Therefore, the following points should be taken into account: unified command should be employed during handling, accurate communication is essential to avoid accidental injuries, and care must be taken to prevent the coke guiding grid from being overturned ； Pay attention to the movement direction of the quench car to prevent it from derailing. When removing coke, prevent burns from red hot coke, as well as scalds; avoid injuries caused by the handles of shovels and the tips of picks; prevent falls from the furnace bed ； When using water to extinguish red coals, prevent steam from causing injury ； During processing, do not drill through the transconductance grid to prevent damage to the vehicle. Observation and handling from the top of the furnace to prevent burns from the furnace heat ； Basement treatment to prevent gas poisoning ； Operate the furnace door etc. to prevent hand injuries and avoid harm caused by coke pushing rods ； Do not touch the electrical wires with iron objects to prevent electric shock.
