Chemical Safety

Procedures for handling chemical spills(泄露) and leaks.

Chemical spills and leaks can be broken down into two basic types: simple spills, which you can clean up yourself and complicated spills, which require outside assistance.

If your spill meets ANY of the following conditions, it is a COMPLICATED SPILL.

? A person is injured; or

? The identity of the chemical is unknown; or

? Multiple chemicals are involved; or

? The chemical is highly poisonous, flammable (可燃的) or reactive ; or

? The spill/leak occurs in a “public space” such as a corridor; or

? The spill/leak has the potential to spread to other parts of the building such as through the ventilation (通风) system; or

? The clean up procedures are not known or appropriate materials are not readily available; or

? The clean up requires a respirator (呼吸器) (including cartridge respirators) to be worn and no personnel have been trained and fit-tested in accordance(一致) with the campus Respiratory Protection Program; or

? The spill/leak may endanger the environment by reaching waterways or outside ground, or by going down a drain

If none of the above conditions are met, the spill is defined as a simple spill. You may clean up simple spills in accordance with Chapter 6 of the Chemical Safety Guide. For consultative assistance, call Division of Research Safety (DSR) at 333-2755.

Many thousands of Chinese are studying at schools in the United States. And writer Liel Leibovitz says the students are following an example that began in the eighteen seventies.

Mr. Leibovitz and writer Matthew Miller joined forces to tell the story of the students in their book, “Fortunate Sons.” The book says China sent one hundred twenty boys from 1872 to 1875 to America to learn about developments that could help modernize their country.

Mr. Leibovitz got the idea for the book about the boys a few years ago when he was traveling with his wife in China.

Mr. Leibovitz learned that Qing government sent a whole delegation(代表团) of boys to learn the ways of the West. The goal was for them to return to China and help their country.

The book says the boys received their American training in Massachusetts, New York, New Jersey and Connecticut. It must have been a very good education. Mr. Leibovitz says the first prime minister of the Chinese Republic completed this program. And so did the first engineer to build a large-scale railroad without foreign help. The same was true of the fathers of Chinese education, diplomacy and the Navy.

The book-writers had only to open some boxes containing the writings of these men to learn about them. Their notebooks, journals, letters and postcards were in English. Mr. Leibovitz said he was lucky to have so much information from events that took place long ago.

The students returned to China after about nine years. They no longer spoke Mandarin(国语) well enough to answer questions. Police welcomed them home by putting them in jail. The young men were released after about a week. But they were given low-level jobs.

Mr Leibovitz says it took about ten years for them to rise to higher positions. He said their story continues today with large numbers of Chinese studying in the United States.

Around four years ago, I received a call from the principal of our school as to the “Parents View” talk the next morning. He asked me to speak to the group. After the call, my whole body became feverish and panicky. The time from his call to the next morning seemed like years. The whole night, I could not sleep with many ominous apprehensions in mind. One of them was to call the principal with regret and tell him that I could not come. Finally, I gathered some courage. I thought, “If I miss this opportunity, surely the school will never invite me again to any of their programs.”

I reached the school in time. Before my turn came, my whole body was trembling. When my turn came and I started speaking, my heartbeat increased and my mouth went dry. I wasn’t even able to read the written speech properly. I was not aware of where I was standing and what I was reading. That was the day when I realized my biggest weakness, Public Speaking.

After my speech, I met with the principal and explained what happened to me. He told me that this happens to everyone. Even great speaker, faced the same things when they started. He suggested that I come again next time.

Around one month later, I was invited to refer to a topic on Motivation. This time I was feeling comfortable. My speech was not only appreciated by the principal as well as the teachers, because I was able to get my idea across to them. They encouraged and praised my efforts.

After delivering is successfully, I became more confident .l said to myself, “If I can speak in front of such a learned audience, like the principal who educates others, I can now speak in front of others too.”

I started delivering lectures in my plant, on various topics like Self Motivation, Personality Development, Personal Excellence, Spoken English and Presentation Skills. This has become a passion for me. I learned that everything is possible if we have the courage to take the first step.

One day I was walking to the mailbox with my dad,when I saw something drop from a tree.I couldn't what it was,so I kept my eyes on the spot as we came near .It was a baby bird,which had fallen from its nest.It had long,awkward wings and feet,and that fought to stay open .It was , so I sat next to it watching while my dad got the mail.I its nest and mother , what would happen to it.

My dad and we had to it;there was nothing we could do.He said if the bird mother smelled any traces(踪迹) of ,she wouldn't go near the again.

As we began to walk away,a woman .”Did it fall out of a nest ?”she asked.

“Yeah.”I answered.

“It a lot. Not much we can do,”she said .”Try not to think about it when you go to sleep tonight.”

I walked the mailbox the next day.The baby bird lay in the grass.

I realize that “Try not to think about it” is the of many people towards things which to provide them with perfect excuses not bothering . The woman wasn't being ; she was actually quite nice. But when everyone says”there's I can do —just try not to think about it,”Where will we finally ? When billions of people try not to think about it When they go to bed at night, there might be millions of fallen birds lying dead and in the grass the next morning.
