1 Product Liability and Safety In design In manufacturing In marketing

2 In Design Plan for safety as a requirement  Fire, explosion,electrocution, contamination,... Design reviews for safety Demonstrate an attitude of concern

3 Design Reviews for Safety It’s not good enough just to make it work Follow established standards  ANSI, NEC, NESC, UL, IEEE, etc.

4 Demonstrate an Attitude of Concern Safety analysis  Preliminary Hazard Analysis, Failure Modes and Effects Analysis, Fault Tree Analysis, etc. Identify high energy systems  Danger! HIGH VOLTAGE Identify critical systems  Failures in what subsystems/components will cause catastrophic failure.

5 Safety Analysis Each system Each subsystem Each board Each component Single-point Multipoint

6 Identify High Energy Systems Guard Isolate Monitor heat Alarm systems Warn when you can’t avoid

7 Identify Critical Systems Controls Power to controls Power to life support Electrical grounding Make redundant Make robust Make fail-safe

8 In Manufacturing Quality assurance Quality control Incoming parts Procedures followed Systems going out  Functional testing  Safety testing

9 In Marketing Warnings as a last resort  Surgeon General’s warning Incorporate human factors engineering  Ergonomics Attorney  Intentional - knowingly and deliberately –Ford Pinto  Negligent - didn’t know, but insufficient safety considerations –no life support backup systems  Reckless - not intentional, but knowingly –Challenger
