How to handle a fire in the coke oven gas collector of a rammed coke oven?

How should one handle a fire breaking out in the cleaning hole of the gas collection pipe during coal charging in a rammed coke oven?
It hasn’t happened in our company either, and I’d like to ask for advice. I’ll give a high score if you reply
Maintain positive pressure and simply cover it with the cleaning lid.
This situation occurs rarely; it is caused by a blockage in the negative-pressure pipeline, as well as an excessively low suction force that does not meet the requirements. The solution is to maintain the pressure in the gas collection duct within the specified range, clean the duct thoroughly and seal it properly, and adjust the pressure so that it remains stable
There is a problem with the empty cover of the airway cleaning system. It’s not suitable; just replace it
Maintain positive pressure in the gas collection pipe, and then use steam to purge the pipe and extinguish the fire.
We haven’t encountered the situation described by the poster in our factory either; raw gas in the gas collection pipe shouldn’t catch fire that easily, right? But since processing is involved, it must be done quickly. Before the fire is extinguished, positive pressure must be maintained, and the gas collection pipe pressure control must be switched to manual mode immediately. Find some rags as soon as possible, wet them and cover it with them; after it’s extinguished, seal the opening with a cover. If coal loading is in progress, it must also be stopped first. If there is a problem with the cleaning hole cover, it needs to be replaced. Using steam should be slower! If it doesn’t go out even for a second, there’s a serious risk!
Summarizing the suggestions from various floors gives a complete picture; it’s great to have so many enthusiastic people.
First, maintain positive pressure in the pipeline and switch from automatic to manual control. Then extinguish the fire, using methods such as steam, wet burlap, or yellow clay. To prevent smoking and flaming at the cleaning holes, the covers of these holes are regularly coated with butter; preventing air leakage is key
