One warm May day, two eighteen – year – old students from San Francisco State College decided to cool off with a swim at Bakers’ Beach. The two students were named Robert Kogler and Shirley O’Neill. They headed out to sea for a distance of 50 metres. Robert was in front.

“Suddenly, I heard him scream,” Shirley recalls. “I looked round and saw this great grey thing going up in the air. The water seemed to be alive.”Robert screamed again. “It’s a shark! Get out of here!”

An eye – witness, Army Sergeant Leo P. Day was on guard at the nearby army post. He saw exactly what happened next. “I could see this boy struggling with the shark in the water,” he said. “The sea was red with blood. He was shouting and signalling someone to go back, go back. Then I saw the girl. She was swimming towards him. She completely ignored his warning.”Shirley reached Robert, and tried to take his hand.“When I pulled, all I could see was his arm, handing by a thread,” she said.

So she put her arm about Robert’s back, and started to swim towards the shore. She kept praying “Don't’ let it attack again!” That journey to the shore seemed to last for hours. At last, as they neared the shore, a fisherman threw them a line, and pulled them both the rest of the way.The young man had lost a lot of blood, and died two and a half hours later, From the teeth marks, experts identified the attacker as a Great White Shark.For what Sergeant Day called “the greatest exhibition of bravery I have ever seen,” the President of the US gave Shirley a medal for bravery.

某厂工人在新扩建的库房内安装消防设施,在安装过程中,不慎造成电线短路,引起库内棉堆突然冒烟起火。由于现场工人不会使用灭火器,火势迅速蔓延。辖区消防中队接到报警后迅速出动,然而厂区无消防栓,消防车要到几公里以外取水,加上风大,火势迅速蔓延到楼上各层。当地调度紧急调集多个消防中队增援,经过近12h的奋勇扑救,大火基本扑灭。其后留下一个消防中队继续扑灭余火,其他消防队相继撤离。为彻底消灭火种,火场指挥部先后调来多台挖掘机和推土机进入厂房,并让该场派出几十名工人协助消防人员清理火种。不久,厂房突然发生倒塌,造成大量人员伤亡。
