Energy Isolation
The ultimate goal of energy isolation on the well site is to prevent the unexpected energization or release of stored energy on the well site.
Inspection of effective energy isolation is important to ensure that potential energy sources are labeled and that proper energy isolation methods are being used.
Assess if energy isolation equipment (i.e. locks, restraints, and blocks) are being used, worn, and correctly labeled. Rig equipment should be assessed to determine if the proper energy isolation methods are being used.
Postings, labeling, and warnings should be checked to make sure they are accurate and visible.
For more information see: OSHA's 29 CFR 1910.147, the American Petroleum Institute (API) Recommended Practice 54, and the IADC Health, Safety and Environmental Reference Guide.
