Are you making an error?

摘要

MOST OF THE WORK ON HUMAN RELIABILITY has been earned out on the last in the long line of people who had an opportunity to prevent an accident,including aircraft pilots and tram drivers as well as plant operators and maintenance workers.Relatively little has been done on ways of improving the reliability or preventing the errors of those who choose the process,carry out the chemical or mechanical design,accept the design,construct the plant and accept the finished facility.Yet these people are usually able to check their work while it may be too late for the operator who omits opening a valve,or the tram driver who passes a red signal,to do so before disaster strikes.
