SafetyLessons for the Pipeline Industry
Construction Safety Guidelines
Construction Safety Guidelines• Personnel Protective Equipment• Excavation Safety • Working Under Utility Power Lines • Pressure Testing
Guidelines Under Development• Vehicle Safety
Excavation Safety
Excavation Safety• OSHA Special Emphasis program• WHY? Protect employees from collapse or
harm from the work in progress..
• WHY? To prevent damage or harm to existing underground facilities.
• WHY? There is always something in the ground that you did not foresee.
Excavation Safety (continued)
• Hazard Assessment –• Analyze what you are faced with• See what has changed since the last shift.• Develop a new plan based on changes found or new
(potential) issues
• Roles and Responsibilities-• Who does what?
• One Calls• Protection of public.• Competent person• Protect other facilities• Stop Work Authority.
Excavation Safety (continued)
• Health and Safety of Employees:• One call current and active• Work plan to dig safely and protect employees/public• Stop work authority• Atmospheric monitoring (exiting utilities, methane in the ground..)
• Access/Egress • Spoil piles protected• Protect employees from accumulating water, moving
equipment or materials (installation of pipe), Spoil piles
Excavation Safety (continued)
• Protective Systems for Excavations• Soil classificationAND• Benching, Sloping and/or Trench Boxes are the most
common methods utilized. • Others methods include timber shoring, hydraulic
shoring, or an engineered excavation.

Overhead Utilities Safety
Overhead Utilities Safety• WHY? Protect employees from overhead
utility contact (or fall if contacted)..
• WHY? To prevent damage or harm to existing overhead utilities.
• WHY? Overhead utilities not only pose a potential danger, but can limit workspace and create “worksite congestion” issues.
Overhead Utilities Safety (continued)
• Hazard Assessment –• Analyze what you are faced with…• See what has changed since the last shift (temperature
shifts/load demands allow change in power line height.
• Revise the standard work plan if workspace is limited.• Develop a new plan based on changes found or new
(potential) issues (Example- newly acquired ROW, other construction in the area…)
Overhead Utilities Safety (continued)
• Roles and Responsibilities-• Who does what?
• Protection of public• Protect other facilities• Protects current work from existing conditions• Plans the proper equipment for safe execution of
work (reach of equipment –vs- height of utility)
• Deploys the use of a spotter• Stop Work Authority
• .
OVERHEAD UTILITIES SAFETY
Hazard Mitigation
• THREE LAYERS OF CONTROLS AT ANY GIVEN TIME…?• INGAA recommends the use of a minimum of 3
layers of controls if overhead utility contact is a potential at your worksite. Layers Include:
1. Spotters2. Signage3. Physical Barriers4. Proximity Alarm(s)5. Utility Controls
OVERHEAD UTILITIES SAFETY
Methods of Protection
Spotters:If using a dedicated spotter, this must be his/her only duty. Must be properly trained (knowledge, established communication with operator, established location, ability/knowledge to act…)
Must be properly equipped (Vest, air horn, radio as needed/warranted)
OVERHEAD UTILITIES SAFETY
Methods of Protection
Signage:Must be visible to all of those working (Low/ground level, Medium, and High) to provide a visible warning device to those on the ground, vehicles and equipment.
OVERHEAD UTILITIES SAFETY
Methods of Protection
• Signage (eye level to those on the ground and in equipment).
OVERHEAD UTILITIES SAFETY
Methods of Protection
OVERHEAD UTILITIES SAFETY
Methods of Protection
Physical Barriers:Located between the equipment and the overhead utility. “Goal Post” – must be highly visible and non-conductive. INGAA recommends the installation on Upstream (coming in) and Downstream(going away) sides of the overhead utility when conditions warrant.
OVERHEAD UTILITIES SAFETY
Methods of Protection
• “Goal Posts” serve as an excellent visible boundary
OVERHEAD UTILITIES SAFETY
Methods of Protection
Proximity Alarms:Physical alarm system installed on the specific machinery. If the machine gets too close, it alerts the operator.
OVERHEAD UTILITIES SAFETY
Methods of Protection
• Proximity Alarms
OVERHEAD UTILITIES SAFETY
Methods of Protection
Utility Controls: “Direct Assistance” from utility owner.Includes, blinding, shielding, insulating, de-energizing, bonding, or taking out of service.
OVERHEAD UTILITIES SAFETY
Methods of Protection
• We cannot forget TRAINING.
Pressure Testing
Pressure Testing Safety• Work procedures• Public protection• Employee Protection
Pressure Testing Safety• WHY? Pressure Testing is designed to find
a FAILURE or FAULTY COMPONENT. • WHY? Plan(s) must be in place to ensure
safety in the event of failure.• WHY? To ensure public safety from a
faulty component or pipeline system, protect the environment, and an prevent interruption of service.
Pressure Testing Safety• Develop a plan.
• Pressures• Medium(s)• Buffers, work areas established. • All aspects of plan are to be included….
Never assume
• Stick to the plan (unless safety or conditions, or something changes)
• Communicate the plan.
Pressure Testing Safety
With these Construction Safety Guidelines or others, there is
one essential key component….
Communication.
Are we always this CLEAR?
