CORRECTLY LATEST UPDATE 2026
- 811 is the national call before you dig phone number.
- Anyone who plans to dig should call 811 or go to their state 811 center's website before digging to
request that the appropriate location of buried utilities be marked with paint or flags, so that they don't
unintentionally dig into an underground utility line. - What is 811?
- Against building foundation walls
- Around and inside adjacent buildings
- Service line taps and valve boxes
- Street intersections and driveways - What are some of the suggested areas for bar hole tests?
- As a best practice, contact the assigner to determine if there are any pending AOCs submitted for the
work order location, that also need to be addressed.
- If the AOC remediation is a different job type, request the appropriate order for the additional work.
- Document the remediation taken for AOCs in the comments on the order. - If the AOC is not causing
immediate risk to life or property, remediate any AOCs that can be addressed while onsite, in
accordance with your training and qualifications. This includes:
- Corrosion
- Damage by outside forces
- Faulty materials
- Earth movement
- Poor workmanship
, - Other abnormal operating conditions (AOCs) - How can leaks be caused?
- Evacuate the occupants from the affected area in an organized manner
- Make sure occupants and bystanders are moved away from the area
- Establish and monitor the perimeter of the gas leak
- Eliminate ignition sources. Notify electric and telephone companies if services need to be disconnected
to eliminate ignition sources - Depending on the situation, what other actions may you need to take in
an emergency?
- If damage to a facility results in escaping gas, you shall report the damage, notify the Integration
Center (they will make all needed calls), continue to make the area safe.
- Park motorized equipment at a safe distance and upwind of the affected area. - Depending on the
situation, what other actions may you need to take in an emergency? (Continued...)
- If gas is detected in the ground, investigate for secondary damage by re-establishing and monitoring
the perimeter of the leakage area.
- Control escaping gas. If the escaping gas has ignited, allow it to burn until the source can be turned off
unless life or property is in danger.
- If building ventilation is required, call for assistance. - Depending on the situation, what other actions
may you need to take in an emergency? (Continued...)
- Lower Explosive Limit (LEL)
- There is not enough gas to ignite, even if an ignition source is present.
- This gas to air mixture is called "LEAN."
- Upper Explosive Limit (EUL)
