DIFFICULTIES IN ESTABLISHING SAFEGUARDS:
Difficulties in establishing Safeguards:
knowledge of the engineering subject
to face hard questions caused by lack of knowledge
sense of security
Nuclear waste disposal problem
in stating probabilities of rare events
understanding of risk based on presentation of facts
assessments based on incorrect/unacceptable assumptions/data
few persons/groups participate in the exercise
the ways by which engineers may try to reduce risks.
the areas of works, engineers should give top priority for product safety.
should believe that accidents are caused by dangerous conditions that can be
corrected. Negligence and operator errors are not the principal causes of
product is made safe, the initial costs need not be high if safety is built
into a product from the beginning. It is the design changes done at a later
date that are costly. Even then life cycle costs can be made lower for the
redesigned or retrofitted product (for safety).
safety is not built into the original design, people can be hurt during testing
should get out of the thinking that warnings about hazards are adequate and
that insurance coverage is cheaper than planning for safety.
takes to make a product safe is to have different perspective on the
design problem with emphasis on safety.
of Improved Safety
door catch introduced on refrigerators
death by asphyxiation of children accidentally trapped inside
catch now permits the door to opened from inside easily
than older types of latches
Handle for Drivers in trains
