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

2. NCSX 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
