Every day we take routine steps to avoid pain and injury. We use sunscreen to shield ourselves from the harmful rays of the sun, put on warm clothes to prevent frostbite and stop at red lights to avoid accidents. We do these and many other things automatically, without even thinking about them. Often times our actions are a direct result of a bad experience that taught us a harsh lesson. We got severe sunburn, shivered from the cold or were involved in a minor fender bender.
Over the past 100 plus years, safety requirements have sometimes developed in much the same way. UL was started as a direct result of our founder, William Henry Merrill, investigating a rash of fires at the 1893 Columbian Exposition’s Palace of Electricity. Requirements were developed in direct response to undesirable events. More recently, however, a methodology known as Hazard-Based Safety Engineering (HBSE) has evolved that formalizes the risk-reduction process. HBSE principles can be used to better understand product safety and to help guide the design and evaluation of appropriate safeguards through analysis of sources, causes and mechanisms of harm.
This presentation will introduce the basic concepts of HBSE and explain how to achieve more accurate safety assessments. We will explore how to identify and analyze hazards to assess the probability of harmful energy transfer and evaluate protective measures intended to reduce the risk of harm based on the severity and probability of such an event.
Topics that will be covered during this presentation include three block models for pain/injury and safety, energy classes, energy transfer and safeguard characteristics. There will also be discussion on how HBSE theory is put to practical use in the development of safety requirements. Specific examples relating to the protection industry will be presented. Finally, Applied Safety Science and Engineering Techniques (ASSETTM) will be introduced. ASSETTM takes HBSE to the next level by expanding HBSE concepts and integrating other safety science and engineering techniques, including risk management, systems and reliability engineering, functional safety and human factors, to address many different forms of harm, hazards and susceptibilities across a broad range of products and applications.
