Ground Disturbance Level II study guide
Ground Disturbance Level II · Work through your exam, one topic at a time.
Ground Disturbance Level II is a Canadian industry safety credential for workers who plan, supervise, or carry out activities that disturb the ground - excavating, trenching, augering, and similar work - where buried pipelines, cables, and other underground facilities may be present. It is typically sought by equipment operators, locators, utility and pipeline personnel, construction supervisors, and health and safety coordinators who need a deeper working knowledge than an entry-level awareness course provides. The Ground Disturbance Level II study guide has 4 sections and about 1,260 words.
01Ground Disturbance Planning and Hazard Assessment
Every ground disturbance begins with a documented plan. The core concepts are scope definition (what activity, what depth, what footprint), a hazard assessment that covers both buried and surface hazards, and a written safe work procedure that ties controls to identified risks.
333 words, about 2 min02Buried Facility Locating and Notification Requirements
Before disturbing ground, the responsible party must notify the one-call or notification service in the area, typically within a defined advance window. The notification triggers member facility owners to locate and mark their buried facilities.
325 words, about 2 min03Safe Excavation and Ground Disturbance Practices
Safe practice means applying the plan in the field: exposing buried facilities by hand within tolerance zones, using soft-dig or vacuum methods where appropriate, and keeping mechanical equipment at a safe distance. Candidates must understand spoil placement, access and egress, shoring and sloping requirements, and the need to protect locate marks.
301 words, about 2 min04Supervision, Roles, and Regulatory Compliance
The supervisor owns the field execution of the plan: verifying notification and locates, confirming the hazard assessment is current, ensuring workers are trained and competent, and stopping work when conditions change. Candidates must understand the roles of the excavator, the facility owner, the locator, and the regulator, and know that responsibility cannot be delegated away by contract language.
