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.

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.
How to report a complicated spill 1. Evacuate(撤退) to a safe location, and alert others to evacuate. 2. Dial 9-911 from a campus phone. 3. Tell the operator you are calling to report a chemical spill at the University of Illinois. 4. Have the following information ready. ? Name of chemical ? Quantity spilled ? Location of spill (Full building name and room number) ? Number of people injured or slashed ? If applicable, the occurrence of a fire or explosion ? Your name and phone number 5. Have someone knowledgeable about the chemical spilled meet the fire department at the main entrance to your building. Take a Material Safety Data Sheet (MSDS) of the chemical, if it is readily available. |
