A few years ago, Pioneer Hi-Bred International, where I was employed. purchased Norand Corporation. Pioneer's sales representatives in the field used Norand hand-held terminals to upload daily sales information and download new price and sales incentive information. Pioneer bought so many of these hand-held-terminals, the economies made the purchase of Norand look interesting. Owning Norand also allowed Pioneer to explore high-technology markets outside agriculture.

But after a few years, the emerging laptop PC technology made the hand-held units obsolete (已废弃的). Pioneer sold Norand at a loss. Pioneer always took a given percent of the annual profits to divide equally among all employees, so our profit-sharing checks were lower than if Pioneer had not purchased Norand. Additionally, my Pioneer stock was lower than it had been before the purchase of Norand. I was not pleased.

The CEO of Pioneer, Tom Urban, made annual formal visits to each of the Pioneer divisions to talk about the state of the business and to listen to employees' concerns. When he walked into the meeting room for his first visit after the sale of Norand, he acknowledged the group, remove his jacket, and neatly folded it across the back of the chair. He loosened his tie, undid his collar and rolled up his sleeves.The next thing he said was the last thing I ever expected to hear a CEO say.

He said, "I made a mistake buying Norand and I am sorry. I am sorry your profit-sharing was lower because of the purchase, and I am sorry your stock was hurt by the purchase. I will continue to take risks, but I am a bit smarter now, and I will work harder for you."

A great man and leader stood before us that day. As I sat listening to him, I knew I could trust him, and that he deserved every bit of loyalty I could give to him and to Pioneer. I also knew I could take risks in my own job.

In the brief moment of silence before the questions started, I recall thinking that follow him into any battle.

A铜业公司是某大型企业的控股子公司。2009年，A铜业公司新建采用艾萨熔炼技术生产铜及硫酸的项目。项目于2009年1月开工建设，9月10日投产运行。项目主要工艺设备有艾萨熔炼炉、电炉、余热锅炉等。艾萨熔炼炉产生的高温烟气进入余热锅炉，经热交换后产生蒸汽，热交换后的烟气经除尘净化系统处理后排出。余热锅炉设计额定蒸汽压力2.5MPa，额定蒸发量35t/h、额定蒸汽温度350℃。
2009年11月24日20时，当班调度甲听到一声巨响，随即在监控系统屏幕上看到余热锅炉有大量蒸汽喷出。甲按照应急救援预案要求立即拉响警报，通知紧急停炉和现场人员撤离，报告公司总经理乙。乙接报后，立即向上级有关部门报告，同时赶往现场指挥救援。21时，经人员清点，仍有5名职工下落不明，乙派2名工人进入现场查看情况，因现场蒸汽太大，2名工人被烫伤。于是紧急外调防护服，救援人员穿上防护服进入余热锅炉房，发现4名职工死亡、1人重伤。
事后查明，事故发生时余热锅炉的运行压力2.3MPa、蒸汽温度310℃，从熔炼炉到余热锅炉的冷却屏波纹金属软管爆裂，大壁高温饱和蒸汽喷出，导致现场人员伤亡。此次事故的直接经济损失为420万元。

根据以上场景，回答下列问题

该起事故的直接原因可能是( )。

A．熔炼炉烟气过高

B．熔炼炉高温烟气压力过高

C．波纹金属软管质量不合格

D．现场职工未佩戴劳动防护用品
