In 1967, in response to widespread public concern aroused by medical reports of asbestos that related deaths, the National Medical Research Council organized a committee of enquiry to investigate the health threats associated with the use of asbestos in the building industry.
After examining evidences provided by medical researchers and building workers and management, the Council published a report which included advices for dealing with asbestos. The report confirmed the findings of similar research in the United States and Canada. Exposure to relatively small quantities of asbestos fibers, they concluded, was directly responsible for the development of cancers, asbestosis and related diseases. Taking into account evidence provided by economists and building industry management, however, the report assumed that despite the availability of other materials, asbestos would continue to play a major role in the British building industry for many years to come because of its availability and low cost.
As a result, the council gave a series of recommendations which were intended to reduce the risks to those who might be exposed to asbestos in working environments. They recommended that, where possible, asbestos free materials should be employed. In cases where asbestos was employed, it was recommended that it should be used in such a way that loose fibres were less likely to enter the air. The report recommended that special care should be taken during work in environments which contain asbestos. Workers should wear protective equipment and take special care to remove dust from the environment and clothing with the use of vacuum cleaner.
The report identified five factors which determine the level of risk involved. The state and type of asbestos is critical to determining the risk factors. In addition, dust formation was found to be limited where the asbestos was used when wet rather than dry.
The choice of tools was also found to affect the quantities of asbestos particles that enter the air. Machine tools produce greater quantities of dust than hand tools and, where possible, the use of the latter was recommended.
A critical factor takes place in risk reduction is the adequate ventilation of the working environment. When work takes place in an enclosed space, more asbestos particles circulate and it was therefore recommended that natural or machine ventilation should be used. By closely following these advices, it was claimed that exposure can be reduced to a reasonably practical minimum.
Exposure to asbestos fibres can cause cancer ______.
A. only when asbestos is used in building industry
B. only when it is used in large quantities
C. even if it is used in small quantities
D. if they are used when wet rather than dry

法律之所以规定免责条款无效的原因有()。A.造成对方人身伤害的,因故意或者重大过失造成对方财产法律之所以规定免责条款无效的原因有()。
A. 造成对方人身伤害的,因故意或者重大过失造成对方财产损失的,行为具有一定的社会危害性和法律的谴责性
B. 一方以欺诈、胁迫的手段订立合同,损害国家利益
C. 恶意串通,损害国家、集体或者第三人利益
D. 造成对方人身伤害的,因故意或者重大过失造成对方财产损失的,这两种行为都可能构成侵权行为责任,如果当事人约定这种侵权行为可以免责就等于以合同的方式剥夺了当事人合同以外的合法权利
E. 不具备合同要件,没有法律约束力的
