The OSHA LOTO Plus Expert Advisor - Public Test Version
October 1999

OSHA's LOTO Plus Expert Advisor - Public Test Version is interactive, expert, diagnostic software. It will help you understand and apply OSHA standards that protect workers from the release of Hazardous Energy.

It is NOT a substitute for the standards. This Expert Advisor is a DRAFT, not a final product. You may not rely on the answers provided by this prototype software.

This Advisor provides an introduction to the scope and logic of several regulations, and summary guidance to facilitate compliance. OSHA has tried to provide accurate information in this program, but you should not rely on the guidance provided by the program as being comprehensive. You should read the full text of the OSHA Standards (29 CFR 1910) which this Advisor determines to be applicable to your work. You should seek professional assistance, if needed.

The LOTO Plus Advisor will interview you about the work on or around equipment that can release mechanical and electrical energy and injure workers. Most questions will have follow-up questions. The LOTO Plus Advisor uses your answers to determine whether and how various standards apply to your work. Then, it prepares your report customized according to your request.

This Advisor is an introduction and guide to certain Standards. It is NOT comprehensive. It is NOT a substitute for safety and health professionals.
