The process of decontamination of the excavator had to be done by chemical means. In this process, we had to use chemical agents that caused dechlorination of the compound. Basically, the chemicals acted by breaking down the compound into chlorine and biphenyl. Furthermore, to ensure completed decontamination, we had to ensure that the excavator had been successfully removed from the warm zone so as not to contaminate the excavator again. ...Download file to see next pagesRead More
