[Safety Production Update] Electrical failures occur frequently in a company’s production facilities – is it due to human error or poor management? Recently, an oil and chemical company experienced frequent electrical equipment failures over three consecutive days – was it due to human error or poor management? Next, our reporter Hai Xiaochuan will take you to the interview site to see what the employees at all levels of the company have to say. Umekawa: First, let’s interview the person in charge of production at the company to find out what electrical accidents have occurred there in recent days. Manager Hai, the person in charge of production: First, I’d like to introduce to you several electrical accidents that have occurred at the company recently. Day 1: The bearing of the air compressor motor overheated; when the operator conducted a inspection, the motor bearing was already red, and the thermometer indicated a temperature as high as 190 degrees. Day 2: The motor of the crude oil pump in the catalytic unit suddenly tripped and stopped, and the interlock system came into effect, resulting in a temporary shutdown of the unit. Day 3: The frequency conversion system of the constant bottom pump in the atmospheric and vacuum distillation unit overheated, causing the pump to stop operating; the workshop promptly started a backup unit, resulting in short-term fluctuations in production. Kai Ogawara: So, Manager Kai, what do you think are the causes of those several electrical accidents? Production manager, Manager H: I believe that these accidents occurred due to the extreme heat, as well as inadequate inspection by the operators, who failed to detect that the equipment’s temperature had risen too high in a timely manner; this ultimately led to the electrical equipment tripping as a result of the high temperatures. Kai Xiaochuan: Thank you, Manager Hai, for explaining to us what happened and the reasons behind it. Next, let’s interview the workers who were involved to see how they view these equipment accidents. Worker A: It’s too hot; it’s unbearable to even walk outside. Probably the equipment can’t handle such heat either, that’s why they’re going on strike in protest against the fact that no air conditioning has been installed for them. Operator Xiao B: It’s just bad luck, I guess. It took several accidents happening in a row for everyone to pay attention. Operator C: The electrical department isn’t managed properly; we’re only responsible for operating the equipment, not anything else. Kai Xiaochuan: Thank you to operators A, B, and C for their participation. Finally, let’s interview electrical engineer N to find out what the reasons behind these incidents are. Electrical Engineer N: Over the past half month, the ambient temperature during the day has remained above 37°, which has had a significant impact on the safe operation of electrical equipment. It’s already difficult for people to stay outside in such conditions, let alone the equipment located in the production areas where the temperature is even higher. Therefore, we classify these incidents as accidents resulting from equipment not being able to function properly due to high ambient temperatures. Kai Xiao Chuan: One last question for Engineer N – what preventive measures do you have in place to address incidents where equipment fails to function properly due to high ambient temperatures? Electrical Engineer N: Our precaution is to use electric fans to cool down the important equipment; this not only helps to cool the equipment but also allows the operators to feel cooler while conducting inspections. Kai Xiao Chuan: Thank you, Engineer N, for your detailed explanation. I believe that with the implementation of appropriate preventive measures, such accidents can definitely be prevented from happening again. This on-site interview is now over; thank you to all our viewers for watching. Aside: Fellow sailors, what do you see in this? How effective is this preventive measure? http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg Petrochemical zone – “Creative Ideas for Energy Saving”: The second phase of this activity is in full swing. http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Industry Forum) 2017: “My Technical Upgrades” in the field of coal chemical industry. http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Industry Forum Website) Registration for chemical engineers – “Learning from Others’ Experiences” activity. http://bbs.hcbbs.com/thread-1808158-1-1.html (Source: Haichuan Chemical Industry Forum Website)
