1 UNDERGROUND FACILITY LOCATOR COMPETENCY PROFILE

2 UNDERGROUND FACILITY LOCATOR COMPETENCY PROFILE The Underground Facility Locator (UFL) Competency Profile (CP) was developed for the Canadian Association of Pipeline and Utility Locating Contractors (CAPULC). CAPULC will create a Competency Profile Committee (CPC) to review the Competency Profile and to send the CP out for public review and comment. CAPULC members may request to join the CPC by ing competencies@capulc.ca. Version DISCLAIMER The information provided in this Competency Profile is intended for general application only and is not intended for use as a complete reference. Terms used in this Competency Profile may vary between facility owners/operators and jurisdictions. It is not a definitive guide to government regulations nor is it a guide to the practices and wholly appli to every locate circumstance. The appropriate regulations, company-specific work practices and manufacturers equipment instructions must be consulted and applied with due diligence. The Canadian Association of Pipeline and Utility Locating Contractors (CAPULC) and Locate Management assume no responsibility whatsoever, for any injury, loss or damage arising from its use. ACKNOWLEDGEMENTS The competencies were developed by Locate Management for Underground Facility Locators (UFLs) with the assistance from the Canadian Association of Pipeline and Utility Locating Contractors (CAPULC) members, industry, facility owner/operators. Their collective input and dedication to the development of the UFL Competency Profile are greatly appreciated by CAPULC. COPYRIGHT All rights reserved.
