1. NCSX Safety MeetingThe Arc Flash Event at SLAC – How Should We Respond? Wayne Reiersen 20 January 2005

2. The SLAC event is a wakeup call • The Event “On October 11, 2004, at approximately 11:15 am, a subcontractor electrician working at the Stanford Linear Accelerator Center (SLAC) received serious burn injuries requiring hospitalization due to an electrical arc flash that occurred during the installation of a circuit breaker in an energized 480-Volt (V) electrical panel.” • Root Cause “Neither SLAC nor Bay Span fulfilled their responsibilities under OSHA and DOE’s ISM policies and procedures to provide the electricians and the laborer with a workplace free of recognized electrical hazards, such as arc flash.” • NCSX Goal Provide a workplace free of recognized hazards through making ISM an integral part of our work

3. What is ISM? ISM is simple and it works

4. Providing a workplace free of recognized hazards • Balance priorities - NEVER encourage, endorse, or tolerate cost and schedule compromising safety • Think ISM - apply the core functions and guiding principles of ISM to your work, use them as a personal checklist • Work safely • No shortcuts • Not just here but at other facilities and at home • Watch out for one another • Show concern - stop your fellow worker when he or she is doing something where someone might get hurt • Respond positively when others do – no negative repercussions when stop work authority is exercised • Take management responsibilities for safety seriously • Set the tone • Address contractors and visitors, not just lab employees • Know what is going on • Engage in the process – provide feedback early and often

5. Where can we do better?
