SAFETY ENGINEERING
CH. 1: INTRODUCTION
PART 2
1
Manmade disaster: the spherical oil tank collapsed. This disaster can be
avoided by applying-at construction stage- corrosion protection fireproofing
material to steel supports. (Lucky no leak)
WHY DO WE NEED SAFETY
ENGINEERING?
Many of the accidents crossed international
borders and affected millions of people in other
countries where others did not extend beyond
national borders but still affected a great
number of people.
3
WHY DO WE NEED SAFETY
ENGINEERING?
Some of the accidents did not kill
anyone.
4
WHY DO WE NEED SAFETY
ENGINEERING?
We all know how quickly technology
is changing
5
WHY DO WE NEED SAFETY
ENGINEERING?
How do we build products with high
quality, cheaply, quickly, and still
safely?
6
WHY DO WE NEED SAFETY
ENGINEERING?
How do governments protect the
public and regulate industry without
negatively impacting competitiveness
or the national economy?
7
WHY DO WE NEED SAFETY
ENGINEERING?
 An
American
Society
of
Mechanical
Engineers’ national survey found that
 Most design engineers were very aware of the
importance of safety and product liability in
designs but did not know how to use the
system safety tools available.
8
WHY DO WE NEED SAFETY
ENGINEERING?
 In fact, most of the engineers who responded
said that the only safety analyses they used
were
 The application of safety factors in design
 Safety checklists, and
 The use of compliance standards
9
WHY DO WE NEED SAFETY
ENGINEERING?
So how do engineers design, build, and operate
systems safely if they have never really been
prepared for it?
10
WHY DO WE NEED SAFETY
ENGINEERING?
To make matters worse
engineers are now more frequently called to
testify in court about failures in their designs.
11
WHY DO WE NEED SAFETY
ENGINEERING?
How do governments protect the public without
damaging the economy or national
competitiveness?
12
WHY DO WE NEED SAFETY
ENGINEERING?
 What it does need is
Considerable
forethought/planning
Systematic
engineering analysis
Methodical approach
to managing risk
