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

Evacuate(撤退) to a safe location, and alert others to evacuate.

Dial 9-911 from a campus phone.

Tell the operator you are calling to report a chemical spill at the University of Illinois.

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.

1.Which of the following situation can be classified as a simple spill?

A. Some spilled liquid causes a fire in the building.

B. Researchers working at Chemical Institution of Illinois.

C. Members of Division of Research Safety.

D. Staff members at a chemical manufacturing company.

5.The purpose of the material above is to ____________ .

A. inform people of the dangers of various chemical spills

B. introduce complicated spills and necessary measures in response to them

C. encourage students to join the campus Respiratory Protection Program

D. compare simple spills and complicated spills

1.D

【解析】

试题分析:化学用品是一件很危险的东西——如果泄漏的话。在这种情况下,要首先分清楚是哪一种泄漏,并及时采取对性的措施减少损失和伤害。

1.细节理解题。A项“一些液体泄漏导致火灾”,B项,“黄绿色的气体从储罐里泄漏”, C项“走廊地板上发现不明红色化学药品”都在第三段有列举。而未被列举的是D项。故选D。

2.细节理解题。根据“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.”可知,复杂的化学泄漏需要远离并呼叫外部支援。故选C

3.Take a Material Safety Data Sheet (MSDS) of the chemical, if it is readily available.”可知,MSDS是Material Safety Data Sheet 缩写,意为材料安全数据表,因此是对化学药品的解释说明。故选B

Humans aren’t the only ones getting a buzz from coffee.Caffeine can improve memory among honeybees and lead to better pollination(授粉).According to a recent study published in the journal Science.

The study was conducted by a team of researchers at Newcastle University in the United Kingdom.They found that the nectar(花蜜)of some flowers,such as those from grapefruit and lemon plants,as well as certain coffee flowers,contains low doses of caffeine.To get bees to feed on these flowers,the team trained the insects to associate food with the smell of the flowers.They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine.After 24 hours,the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants.

Professor Geraldine Wright led the researchers.“Remembering floral traits(花部特征)is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,”Wright said in a statement.

Improved memory led to the better pollination.That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate.This also suggests that caffeine plays a role in improving the bees’ability to search for food.

Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals.“The change is similar to that produced by caffeine in neurons(神经元)associated with learning and memory in the rat brain,”Wright said.

Bee populations have declining since 2007.The dramatic drop in the insects’numbers has serious effects for ecosystems and the farming industry.Bees are needed in the reproduction of crops and spreading wild flower species.Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.

1.Which of the following is mentioned in the passage?

A.Caffeine has no effect on the rat brain.

B. Bee population has been increasing.

C.The nectar of lemon plants contains caffeine.

D.Bees dislike nectar from sweetened flowers.

2.After reading the passage,John,who works in the farming industry, will probably feel ____________.

A.annoyed B.angry C.nervous D.excited

A.improved memory—caffeine nectar—better pollination

B.caffeine nectar—improved memory—better pollination

C.improved memory—better pollination—caffeine nectar

D.caffeine nectar—better pollination—improved memory

4.What section of a newspaper may this passage be taken from?
