II. R&D Worker Training Lloyd Gordon Los Alamos National Laboratory
Project Area 5 Awareness/Focused Training - R&D SCOPE • Provide recommendation for a standardized approach for Electrical Safety Modules on specific topics for workers in the R&D laboratory environment. • Provide recommendation for a standardized approach for training for contractor Electrical Safety Officers.
What is an R&D Worker? • Scientists, engineers, technicians, and others who: • work in an R&D laboratory environment performing research and development, often with custom built, or state-of-the-art equipment. • The degree of electrical work can vary from: • the operation of custom built equipment, largely protected by engineering controls, to • the design, fabrication, and maintenance of custom built R&D equipment, to • working inside of R&D equipment as a part of the research process
Electrical or Non-electrical Worker? • The difference between a facility electrical worker (e.g., electrician) and a facility non-electrical worker (e.g., welder, carpenter, heavy equipment operator) is clear. • An electrician/lineman has a formal licensing process. • An electrician/lineman’s job is electricity. • Experimental R&D workers learn some elements of electrical technologies in their academic education, especially in their specific fields. • There is no specific formal record of this electrical training. • They may know their specific equipment very well. • Working with electricity may only be a small part of their job. • Is the R&D worker a casual electrical worker?
Some Statistics • R&D electrical workers may account for 90% of the DOE complex electrical workers, BUT • R&D workers account for less than 30% of the electrical events in the complex. • R&D electrical incidents tend to be shocks or near shocks (NOT LOTO, arc flash, or penetration/excavation)
Project Area 5 Awareness/Focused Training - R&D • Recommended Approach: • Develop a General Training Module: Basic Electrical Safety for R&D Workers • Most sites have a variation of this. • Develop Targeted Training Modules for specific R&D Worker Groups • Few sites have these, need to be available. • Develop a Targeted Training Module for Electrical Safety Officers • A few sites have this, need to be available. • Identify and recommend other available training sources
1. Core Training for R&D Electrical Workers • All R&D sites have some form of basic training for R&D workers. • There is considerable variation in: • method of delivery (live class, self study, web-based) • length • retraining requirements (none to 3 years) • material (a function of a site’s electrical safety program requirements) • Problem! • No site accepts the electrical safety training from other sites. Some roving scientists have to take basic R&D electrical safety multiple times (example, accelerator scientists working at LANL, SLAC, BNL)
1. Core Training for R&D Electrical Workers - cont. • As electrical safety programs become more consistent across the complex, some components of the core training for R&D electrical workers can be identical • Common elements of training can be available for use by any site: • electrical hazard classification • unlisted electrical equipment approval • PPE for R&D workers • ISM for electrical work • The ONLY unique aspect of R&D electrical safety training at a site are the site’s unique features of their program requirements.
