Red coke landing plan
Thread Content
Under what circumstances can red coking fall to the ground? What are the plans in place to deal with such situations? Thank you all for your advice!
There are many cases of red coke falling to the ground, such as when the coke quenching vehicle on the coke side is not in the correct position, and the signalman blows the coke pushing signal. Prevention methods can only start with operational steps. Strengthen coordination among various positions while confirming their roles.
I believe that focusing solely on operational aspects is not sufficient; apart from operations, equipment-related issues can also lead to accidents involving red coke falling to the ground. Examples include corrosion and deformation of the coke quenching tracks, the coke quenching vehicle dropping off the track during the quenching process, failure of the main control system that regulates the vehicle’s movement, sudden failures in the reducers or motors responsible for controlling movement, power outages in the electrical systems, or broken or faulty brushes. There are many other possible causes that can be analyzed further. By identifying problems promptly through regular inspections and operations, it is possible to eliminate potential hazards at an early stage, thereby preventing accidents from occurring in the first place
The occurrence of red coke falling to the ground is, of course, due to the coke not being discharged from the coke car or quenching car at the designated location, which results in the red coke falling to the ground
In 80% of cases, the occurrence of red coking is due to careless human handling.
It can be said that in over 80% of cases of red coking, the issue is caused by improper human operation; carelessness is the root cause of such accidents. The main reason is the absence of supervisors to monitor the coking process. Additionally, improper operation by the drivers of the cars used for pushing, stopping, and extinguishing coke, as well as a lack of skill and inadequate emergency response measures, are also key factors
There are many reasons why red coke ends up on the ground, but operational errors can be considered the main cause. Once red coke lands on the ground, it is necessary to quickly mobilize personnel to extinguish it, and then remove it as soon as possible.
Red coke on the ground: It’s ultimately a problem with equipment manufacturing and maintenance! ! ! The four major vehicles of coke ovens are designed and manufactured with due consideration for errors in operation; they are all equipped with operation interlock signals, error-push interlock signals, and more! There is a push-block-extinguish sequence via the fourth slider! Currently, many coking plants are facing problems where the quality of the four major vehicle manufacturing companies is very low, or the skill levels of the maintenance staff at those companies are insufficient, resulting in machine failures and casualties!
After the red coke falls to the ground, it is necessary to extinguish it as quickly as possible and move any vehicles that are above or nearby it away. Plans for dealing with such situations should take into account the availability of fire-fighting equipment, the organization of emergency response teams, etc.; in addition, drills should be conducted to help operators master the appropriate methods for handling such emergencies. To prevent the red coke from falling to the ground: 1) it is essential to ensure that all three vehicles are in the correct position before proceeding with the pushing or receiving of the coke; 2) the use of automated technologies such as interlocking systems and automatic positioning is important; 3) safety training and education for operators should be provided on a regular basis
The main reason for the lack of three-car interlocking is likely equipment maintenance; in the case where there is no such interlocking, it is a matter of the responsibility level of the staff on duty.
